For Adults with ADHD: What Should Your Doctor be Doing for your ADHD?

Recognizing whether your ADHD is being managed appropriately requires an understanding of what constitutes effective treatment. Here are some indicators of proper ADHD treatment:

Recognizing whether your ADHD is being managed appropriately requires an understanding of what constitutes effective treatment. Here are some indicators of proper ADHD treatment:

Comprehensive Evaluation: An appropriate diagnosis of ADHD involves a comprehensive evaluation, including medical history, clinical interviews, and assessment tools. It should also exclude other conditions that may mimic ADHD.

Clear Communication: Your doctor should provide a clear explanation of ADHD, its symptoms, treatment options, potential side effects, and expected outcomes. They should answer your questions patiently and help dispel any misconceptions.

Individualized Treatment Plan: ADHD treatment often involves a combination of medication, psychotherapy, and lifestyle changes. Your doctor should tailor the treatment plan to your specific needs, symptoms, and life circumstances.

Medication Management: If medication is part of your treatment plan, your doctor should monitor its effects and side effects closely, adjusting the dosage as necessary. Remember, the aim is to maximize benefits and minimize side effects.  Much research shows that it is usually best to start treatment with an FDA approved medication.  If your doctor decides otherwise, you should ask why.

Psychotherapy and Coaching: Pills don’t provide skills.  Many adults with ADHD never acquired life skills due to untreated ADHD. Cognitive-behavioral therapy (CBT) is beneficial for managing ADHD. Your doctor might recommend this and refer you to a psychologist, or they might provide some elements of these services themselves.  

Regular Follow-Ups: Regular follow-ups are critical to assess the effectiveness of the treatment plan and to make necessary adjustments. Your doctor should be tracking your progress and adapting your treatment as needed.

Empowering You: A good doctor will support you in managing your ADHD, providing education, resources, and tools that empower you to lead a healthy, fulfilling life.

Focus on Strengths: ADHD can come with strengths, such as creativity, dynamism, and the ability to think outside the box. An effective healthcare provider will help you leverage these strengths.

Involvement of Loved Ones: Depending on your circumstances, involving your loved ones in your treatment process can be beneficial. They can provide additional support and understanding.

Co-ordinating with Other Healthcare Providers: If you have other healthcare providers involved in your care, your doctor should communicate and coordinate with them to ensure consistent and comprehensive care.

Remember, you have the right to seek a second opinion if you feel your ADHD is not being appropriately managed. Trust your instincts and advocate for your health. It may also be helpful to join ADHD support groups (online or offline) to connect with others who share similar experiences. Their insights and recommendations could be beneficial.  Also keep in mind that achieving an optimal outcome for one’s ADHD often requires the doctor to try a few different medications as it is not currently possible to predict which patients do best on which medications.

Meta-analysis reports weak evidence for mindfulness interventions for children and adolescents with ADHD

Meta-analysis Reports Weak Evidence for Mindfulness Interventions for Children and Adolescents with ADHD

Mindfulness involves focusing on the present moment. Mindfulness meditations include choosing a point of focus, such as breathing, and focusing on it continuously. They may also involve focusing single-mindedly on body movements, as in Yoga.

Mindfulness involves focusing on the present moment. Mindfulness meditations include choosing a point of focus, such as breathing, and focusing on it continuously. They may also involve focusing single-mindedly on body movements, as in Yoga. This could be potentially useful because in focusing on the present moment with attention and emotion regulation, it addresses regulatory capacities impaired in ADHD.

Previous studies of efficacy of mindfulness interventions have been inconclusive, limited by low methodological quality. A Taiwanese study team tried to remedy this with a fresh meta-analysis of randomized controlled trials (RCTs).

The team included three types of RCTs: yoga intervention, mindfulness-based psychological intervention, and mediation training. There was a lot of variation in the length of individual sessions and in the total number of hours of intervention.

Five studies used a waiting list control group. Two studies used treatment as usual or standard care as control groups. Only four studies followed best practices of using an active control group, such as a listening task, behavioral therapy, cooperative activities, or an emotional education program.

Twelve studies scored between 4 and 7 points from a possible total of 10 points, suggesting at best moderate methodological quality. More seriously, there was no indication of patient and therapist blinding.

With all these limitations, the one nominally positive result was for improvement in ADHD symptoms. A meta-analysis of seven RCTs with a combined 184 participants found a large reduction in ADHD symptoms post-treatment that did not persist at follow-up a couple months later. But between-study variation (heterogeneity) was extreme, with evidence of publication bias. The authors did not offer a revised estimate of efficacy based on the standard trim-and-fill adjustment.

Two additional meta-analyses, of seven RCTs with 200 participants, and seven RCTs with 215 participants, found no improvement in either externalizing or internalizing behaviors post-treatment. This time there was no sign of publication bias in either case. For externalizing behaviors, there was negligible heterogeneity, and moderate heterogeneity for internalizing behaviors.

A meta-analysis of four RCTs combining 122 participants found a moderate improvement in child mindfulness post-treatment, but it was not statistically significant.

Siblings of Those With ADHD at Higher Risk for ADHD & Other Disorders

Israel-wide population study:siblings of individuals with ADHD have highly elevated risk of ADHD, slightly elevated risk of anxiety and personality disorders, no greater risk for other disorders or low IQ

Israel has a military draft that applies to males and females alike, except orthodox women and orthodox male seminary(yeshiva) students, who are exempt. Upon turning 17 every Israeli undergoes a medical review, including both a physical and psychiatric assessment, in preparation for the draft. The Draft Board Registry maintains comprehensive health information on all unselected Israelis until they turn 21. The registry also tracks all family members of draft registrants, including full siblings.

An Israeli study team used registry records from 1998 through2014 to obtain data for a total of over a million individuals (1,085,388). Because of the exemption for orthodox women, 59% were male.

The team identified 903,690 full siblings in the study population (58% males), including 166,359 male-male sibling pairs, 104,494 female-female sibling pairs, and 197,571 opposite-sex sibling pairs.

Next, the team identified all cases in the study population with a diagnosis of a psychiatric disorder, low IQ (≥2 standard deviations below the population mean), Type-1 diabetes, hernia, or hematological malignancies. It matched each case with ten age- and sex-matched controls selected at random from the study population. Then, for each case and case-matched controls, it identified all siblings.

There were 3,272 cases receiving treatment for ADHD, 2,128 with autistic spectrum disorder, 9,572 with severe/profound intellectual disability, 7,902 with psychotic disorders, 9,704 with mood disorders, 10,606with anxiety disorders, 24,815 with personality disorders, 791 with substance abuse disorders, 31,186 with low IQ, 2,770 with Type-1 diabetes, 30,199 with a hernia, and 931 with hematological malignancies.

Draftees with ADHD were five and a half times more likely to have a sibling with ADHD than controls.

There were no significant associations between ADHD and any of the somatic disorders - Type-1 diabetes, hernia, or hematological malignancies - nor between ADHD and low IQ.

There were also no significant associations between ADHD and autism spectrum disorder, severe/profound intellectual disability, mood disorders, and substance use disorders.

On the other hand, draftees with ADHD were more than 40% more likely to have siblings with anxiety or personality disorders than controls.

Surprisingly, draftees with ADHD were less than half as likely to have siblings with psychotic disorders than controls.

There were some limitations. The psychiatric classification system used by the Israeli military did not permit assessing the risk of bipolar disorder and depression separately. That meant having to use a broader category of mood disorders, including both disorders. In addition, the military diagnostic system does not allow diagnosis of comorbid psychiatric disorders in the same individual, instead of assigning only the most severe diagnosis.

Meta-analysis suggests ADHD contributes significantly to alcohol use disorder in persons with comorbid bipolar disorder

Meta-analysis suggests ADHD contributes significantly to alcohol use disorder in persons with comorbid bipolar disorder

Bipolar disorder is a severe mental illness that afflicts over one in fifty persons worldwide. About a quarter of those with bipolar disorder also has alcohol use disorder (AUD). This in turn complicates the treatment of their bipolar disorder. It exacerbates their symptoms, makes them more likely to be suicidal, and increases the risk of hospitalization.

More than one in five persons with bipolar disorder also have ADHD, which is likewise known to be correlated with AUD. To what extent does ADHD contribute to AUD in persons with comorbid bipolar disorder?

A European study team recently conducted a systematic search of the peer-reviewed medical literature to address that question. The team identified eleven studies with a combined total of 2,734 participants that could be aggregated to perform a meta-analysis.

They found that persons with comorbid ADHD and bipolar disorder were two and a half times more likely to be diagnosed with alcohol use disorder than persons with bipolar disorder but no ADHD.

Between-study heterogeneity was negligible, and there was no sign of publication bias.

The authors concluded, "At least a portion of the high rates of AUD in BD may, thereby, be related to comorbid ADHD. Longitudinal studies are needed to clarify the nature of this relationship."

What We Know About ADHD in Female Populations

A new consensus statement updates what is known about ADHD in girls and women, and offers professional advice

Boys are three times as likely as girls to be diagnosed with ADHD, and anywhere from three to sixteen times more likely to be referred for treatment.

An international team of experts recently published a consensus statement addressing this discrepancy and offering guidance to rectify the imbalance and improve diagnosis and care for girls and women with ADHD. Here are some key conclusions.

ADHD symptoms:

-Experts caution that ADHD behaviors typically express themselves differently in boys than in girls.
-That in turn leads to gender-based biases in teachers and parents. In two studies in which teachers were shown vignettes of individuals with typical ADHD behaviors, switching from female to male names and pronouns led to higher rates of referral for support and treatment.

Comorbidity:

-A major reason for this different expression of ADHD in boys is that they have much higher rates of comorbid externalizing disorders, such as the conduct disorder and oppositional defiant disorder, leading them to break rules and get into fights in school. This no doubt contributes to lower rates of referral for girls.
-On the other hand, females are more likely to have comorbid internalizing disorders, such as emotional problems, anxiety, and depression. These may be interpreted as primary conditions, and the link to ADHD is missed altogether.
-Because ADHD has come to be associated with many externalizing disorders, it is then easy to fail to identify it when it is associated with internalizing disorders such as eating disorders.
-Untreated ADHD in girls can increase the risk of substance use disorders.

Associated vulnerabilities:

Children with ADHD are more likely to be unpopular with their peers and to experience rejection. Whereas boys are more likely to experience that rejection in physical ways, girls are more likely to experience it in social ways and through cyberbullying. That, in turn, contributes to lower self-esteem, which could explain some comorbid internalizing disorders.

Symptoms of hyperactivity/impulsivity, one of the two key components of ADHD, are associated with higher rates of risk-taking behavior:

- Like males with ADHD, females with ADHD have higher injury rates.
-Both males and females with ADHD are more likely to underachieve in school or drop out altogether.
-Overall, adolescents with ADHD become sexually active earlier, have more sexual partners, and are more frequently treated for sexually transmitted diseases than their normally developing peers. That also leads to higher rates of teenage and unplanned pregnancies.
-As with males with ADHD, females with ADHD have higher rates of criminal behavior than normally developing peers. While females with ADHD are still half as likely to be convicted of a crime than males with ADHD, one study showed they nevertheless are eighteen times more likely to be convicted of a crime than normally developing females.

Compensatory or coping behaviors:

- Girls may turn to drink alcohol, smoking cannabis, smoking cigarettes, or vaping nicotine to cope with emotional anguish, social isolation, and rejection.
-Some girls may seek to build social support through high-risk activities such as joining a gang, becoming promiscuous, and engaging in criminal behavior.

Triggers for possible referral

Ages 5-11:

-Bedwetting, nail-biting

Ages 5-16:

-Early sexualized behavior

Ages 5-18:

-Suspensions, expulsions, frequent detentions
-Poor attendance/truancy
-Consistent lateness, poor organization
-Academic difficulties, low academic self-esteem
-Conduct problems, conflicts with parents and peers
-Bullying (usually as victims)
-Regular tobacco and alcohol use
- Obesity and other eating disorders
- Repeated injuries
- Sleep difficulties
- Executive function difficulties
- Extreme emotional meltdowns

Ages 12 and above:

- Relationship problems, anxiety about relationships
- Social rejection, isolation
- Substance abuse, including alcohol
- Risky sexual behavior
- Underage or unwanted pregnancy
- Delinquency or criminal behavior (including shoplifting, vandalism)
- Low self-esteem
- Self-harm, suicidality

Ages 16 and above:

- Dropping out of school
- Losing jobs
- Parenting problems
- Criminality
- Financial difficulties
- Traffic crashes
- Internalizing conditions: depression, anxiety

Ages 18 and above:

- Gambling problems, compulsive shopping
- Personality disorder
- Chronic fatigue syndrome
- Fibromyalgia

The key message is not to disregard females because they do not present with the externalizing behavioral problems, or the disruptive, hard-to-manage boisterous, or loud behaviors typically associated with males with ADHD.

Diagnosis

The authors emphasize that "comprehensive assessment should be completed to accurately capture the symptoms of ADHD across multiple settings, their persistence over time, and associated functional impairments. High rates of comorbidity are typically present. The assessment process is typically tripartite, involving the use of rating scales, a clinical interview, and ideally objective information from informants or school reports."

Rating scales: Ideally rely on those that provide female norms, making them more sensitive to female presentation.

Clinical interviews:

-Be mindful of age-appropriate, common-occurring conditions in females with ADHD, including autistic spectrum disorder, tics, mood disorders, anxiety, eating disorders, fibromyalgia, and chronic fatigue syndrome.
- Be alert to signs of self-harming behaviors(especially cutting), which peak in adolescence and early adulthood.
-Given that heritability of ADHD is high, ranging between 70-80% in both children and adults, be mindful that informants who are family members may also have ADHD (possibly undiagnosed) which may affect their judgment of "typical" behavior. The assessor should obtain specific examples of behavior from the informant and use these to make clinically informed judgments, rather than relying upon the informants' perception of what is typical or atypical.

Treatment

Pharmacological:

- Recommendations for medication do not differ by sex, except that pharmacological treatment is generally not advised during pregnancy or breastfeeding.
- A systematic review and network meta-analysis recommended methylphenidate for children and adolescents and amphetamines for adults, taking into account both efficacy and safety. Larger confidence intervals about the tolerability and efficacy of bupropion, clonidine, and guanine were reported, indicating less conclusive results about the efficacy and tolerability of these oral medications. The use of medication should be followed up over time to verify if medications are effective and well-tolerated, and to manage the effects of related conditions(e.g. anxiety, depression) if they emerge.

Non-pharmacological:

- Cognitive behavioral therapy (CBT) together with psychoeducation (which can be provided to both patients and parent/guardians together or independently) are the best forms of psychological treatment.
- Parents and other guardians of teenage girls need to be shown how to identify deliberate self-harming or risky behavior.
- Adolescent girls may require assistance in addressing risky behavior (sexual risk, substance misuse) and improving self-management. Girls with ADHD are more vulnerable to sexual exploitation and have higher rates of early and unwanted pregnancy.
- Adults are more likely to require interventions to address employment problems, child-rearing, and parenting. Women with ADHD are also more vulnerable to sexual exploitation, including physical and sexual violence.
- Interventions should support attendance and engagement with education to avoid early school-leaving, diminished educational attainment, and associated vulnerabilities. While externalizing conditions have a greater impact on classroom behavior, internalizing conditions affect motivation and thus the ability to benefit from education.

Institutional outreach

- Educational, social care, occupational, and criminal justice system professionals should be trained to improve the detection and referral of ADHD in girls and women.
- Flexible learning systems and support with childcare can help women with ADHD return to education after having a baby.
- Depending on the country of residence, women who disclose their disability to their employer may be entitled to reasonable adjustments to the workplace to accommodate their condition.
- Low to no-cost apps are available to assist persons with ADHD with itineraries, lists, and reminders.
- Career planning should take into account that some occupations may provide a better fit for women with ADHD: "some individuals with ADHD show a preference for more stimulating environments, active, hands-on, or busy and fast-paced jobs."
- Persons with ADHD, both male and female, make up roughly a quarter of the prison population: "Evidence indicates that ADHD treatment is associated with reduced rates of criminality, is tolerated and effective in prison inmates, and improves their quality of life and cognitive function. This has led to speculation that effective identification and treatment of ADHD may help to reduce re-offending."

The authors concluded, "To facilitate identification, it is important to move away from the previously predominating disruptive boy stereotype of ADHD and understand the more subtle and internalized presentation that predominates in girls and women."

Assessing Co-occuring Disorders in Relatives of Those With ADHD

Taiwan Population Study Assesses Comorbidity of Psychiatric Disorders among First-degree Relatives of Those with ADHD

ADHD patients were found to be seven times more likely than controls to have first-degree relatives with ADHD.

Taiwan's National Health Insurance program is a single-payer system that covers 99.6% of the island's 23 million residents. It includes family relationships.

This enabled a Taiwanese study team to examine the comorbidity of psychiatric disorders among close relatives in the entire population over eleven years, beginning at the start of 2001 and concluding at the end of2011.

For greater certainty of diagnosis, only persons twice diagnosed with the same psychiatric disorder were included as index individuals. There were 431,887 index patients, 152,443 of whom were ADHD index patients.

These index patients were then compared with all of their first-degree relatives (FDRs): parents, children, siblings, and twins. This produced 1,017,430 patient-FDR pairs, of which 401,301 were ADHD patient-FDR pairs.

Next, four controls were matched by age, gender, and type relative to each case, resulting in 4,069,720 control pairs.

After adjusting for age, gender, urbanization, and income level, ADHD patients were seven times more likely than controls to have first-degree relatives with ADHD. They were also seven times more likely to have FDRs with major depressive disorder, four times more likely to have FDRs with autism spectrum disorder, twice as likely to have FDRs with bipolar disorder, and 80%more likely to have FDRs with schizophrenia.

Study: Methylphenidate Reduces Traffic Accidents in Persons with ADHD

Nationwide cohort study: methylphenidate reduces traffic accidents in persons with ADHD

Taiwan has a single-payer healthcare system that covers virtually every inhabitant (99.5%). That makes it relatively easy to track healthcare issues using its comprehensive National Health Insurance Research Database.

This database maintains a subset, the Longitudinal Health Insurance Database (LHID), consisting of a million persons, with no significant differences in sex, age, or healthcare use from the parent database.

A Taiwanese research team used the LHID to identify 114,486 individuals diagnosed with ADHD from 1997 to 2013. It then compared their motor vehicle (including motorcycles, which are extremely common in Taiwan) crash patterns with 338,261 normally developing controls from the same database.

Adjusting for sex, age, and psychiatric comorbidities, persons with ADHD were about a fifth (19%)more likely to be in traffic crashes. Breaking it down further by sex, women with ADHD were no more likely to be in crashes, but men with ADHD were about a quarter (24%) more likely than their healthy counterparts.

Since the database also tracks pharmaceutical prescriptions, the team also looked into the effect of methylphenidate (MPH), the medication that is the first-line treatment for ADHD under Taiwanese guidelines, and the only approved stimulant. Atomoxetine, a non-stimulant, is used where MPH is either ineffective or not indicated for any other reason and is only used in 4% of all cases.

Of the 114,486 persons diagnosed with ADHD, 89,826 used MPH, and 24,660 did not.

Compared with persons with ADHD who were not on methylphenidate, those with ADHD who were on MPH for 180 days (roughly half a year) or less had 77% fewer accidents, and those on MPH for over 180 days had 93% fewer accidents. This strong dose-response relationship is suggestive of a causal relationship, with MPH perhaps reducing impulsive behavior, particularly among young men with ADHD.

The team also conducted within-person analyses, comparing times when persons with ADHD were taking MPH with periods when they were not. These showed no effect within 30 days of use, rising to a 65%reduction in crashes within 60 to 90 days of use, which was barely outside the 95% confidence interval (p = .07), very likely because of "the extremely low incidence of transport accidence (i.e. 0.6%)enlarged the confidence interval."

The authors concluded, "All registration medical claim data came from the nationally-representative sample of NHI, minimizing the selection and recall bias. By excluding transport accidents before ADHD diagnosis, we have precluded the reverse association between ADHD and road traffic accidents as much as possible. The advantage of the between-subjects comparison was that we were able to examine the MPH effect in different dose groups. However, confounding by indication cannot be eliminated. For example, those with a severe degree of ADHD symptoms, an exhibition of risky behaviors, or comorbid with other psychiatric illnesses were more likely to be prescribed medication. Hence, we also performed within-subject comparisons to adjust for time-invariant factors."

Transport safety thus offers another compelling reason to treat ADHD symptoms. Methylphenidate in particular seems to be especially effective in reducing traffic fatalities and injuries.

Meta-analyses Suggest Physical Exercise is Effective Tool in Treating ADHD

Two meta-analyses suggest physical exercise is an effective tool in treating ADHD

Two recent meta-analyses, one by an Asian team, and the other by a European team, have reported encouraging results on the efficacy of physical exercise in treating ADHD among children and adolescents.

One, a Hong Kong-based team (Liang et al. 2021) looked at the effect of exercise on executive functioning.

The team identified fifteen studies with a combined total, of 493 participants that met the criteria for inclusion. As the authors noted, "only a few studies successfully blinded participants and therapists, due to the challenges associated with executing double-blind procedures in non-pharmacological studies."

After adjusting for publication bias, the meta-analysis of the fifteen studies found a large improvement in overall executive functioning.

The studies varied in which aspects of executive functioning were addressed. A meta-analysis of a subset of eleven studies encompassing 406 participants found a large improvement in inhibitory control. A meta-analysis of another subset, of eight studies with a total of 311 participants, found a large improvement in cognitive flexibility. Finally, a meta-analysis of a subset of five studies encompassing 198 participants found a small-to-medium improvement in working memory.

Nine studies involved acute (singular) exercise interventions lasting 5 to 30 minutes, while twelve studies involved chronic (regular) exercise interventions ranging from 6 to 12 weeks, with a total duration of 12 to 75 hours. The chronic exercise was more than twice as effective as acute exercise. The former resulted in large improvements in overall executive functioning, the latter in small-to-medium improvements.

No significant differences were found between aerobic exercises (such as running and swimming) and cognitively engaging exercises(such as table tennis and other ball games, and exergaming ... video games that are also a form of exercise, relying on technology that tracks body movements).

The authors concluded that "Chronic sessions of exercise interventions with moderate intensity should be incorporated as a treatment for children with ADHD to promote executive functions."

Meanwhile, a German study team (Seiffer et al. 2021) looked at the effects of regular, moderate-to-vigorous physical activity on ADHD symptoms in children and adolescents.

They found eleven studies meeting their criteria, with a combined total of 448 participants. A meta-analysis of all eleven studies found a small-to-moderate decline in ADHD symptoms. However, the three studies with blinded outcome assessors found a large and statistically highly significant decline in symptoms, whereas the eight studies with blinded outcome evaluators found only a small decline that was not statistically significant.

When compared with active controls using pharmacotherapy in a subgroup of two studies with 146 participants, pharmacotherapy held a small-to-moderate advantage that fell just short of statistical significance, most likely because of the relatively small sample size.

The authors concluded that moderate to vigorous physical activity (MVPA) "could serve as an alternative treatment for ADHD," but that additional randomized controlled trials "are necessary to increase the understanding of the effect regarding frequency, intensity, type of MVPA interventions, and differential effects on age groups."

Genetic Co-Aggregation: The Possible Link Between Autoimmune Disease and ADHD?

Two nationwide population studies on opposite sides of the world confirm links between autoimmune diseases and ADHD, suggest they are from genetic co-aggregation

Both Taiwan and Sweden have universal single-payer health insurance systems that in effect track their entire national populations. With detailed health and other records on millions of individuals, with no significant exclusions, one can essentially eliminate sampling error, and also explore how associations vary by degree of familial/genetic relationship.

A Taiwanese research team used the Taiwan National Health Insurance Research Database to follow 708,517 family triads (father-mother-child) from 2001 through 2011. That's a total of over 2.1 million persons. The database covers over 99% of Taiwan's population.

Noting that previous studies had found links between maternal autoimmune diseases and ADHD in their offspring and that research on associations with paternal autoimmune diseases had been inconclusive, they were particularly interested in exploring the latter.

Children born from 2001 through 2008 were enrolled in the study. The investigators then noted the presence or absence of any autoimmune disease in their parents from 1996 through childbirth.

In Taiwan, expert panels review diagnostic information of severe systemic autoimmune diseases to confirm the diagnosis. Once confirmed, patient co-payments are waived. ADHD diagnoses are by board-certified psychiatrists.

To reduce the effect of confounding variables, adjustments were made for family demographic data (income level and residence), parental ages, parental mental disorders, and sex of children.

The presence of any maternal autoimmune diseases was associated with a 60% greater risk of ADHD in offspring. The risk was especially elevated for inflammatory bowel diseases (2.4 times the risk) and ankylosing spondylitis (twice the risk).

The presence of any paternal autoimmune diseases was also associated with an elevated risk of ADHD in offspring, although only about half as much as for maternal autoimmune diseases, with a 33% greater risk overall. The association was especially pronounced for psoriasis and ankylosing spondylitis, both doubling the risk of ADHD in offspring.

Meanwhile, half a world away, a joint Swedish, Norwegian, and U.S. team used the Swedish national registries to dig further into these associations. They did this by examining data not only from mothers and fathers, but from full siblings, aunts, uncles, and cousins as well, to probe genetic links.

The team used the Swedish registers to identify 5,178,225 individuals born in Sweden between 1960 and 2010 for whom the identity of the biological mother was known, excluding all who died or emigrated before age 10. They then used the registers to identify the aforementioned relatives.

The researchers only included autoimmune diseases with at least two thousand diagnosed individuals in the cohort, to avoid small sample effects.

They adjusted for sex and year of birth, but not "for another covariate that is often adjusted for (e.g. maternal education, family income, parental psychiatric disorder, parental AD [autoimmune disease] as these are likely not true confounders of the association between ADHD and ADD, but may rather represent either mediator between ADHD and AD's, or proxies of ADHD and/or AD risk or alternatively proxies for the associations we aim to measure."

The team found statistically significant associations between ADHD and autoimmune diseases in all categories of relatives. Mothers of children with ADHD were 29% more likely to have an autoimmune disease than those of typically developing children; fathers were 14% more likely to have an autoimmune disease; full siblings 19% more likely; aunts 12% more likely; uncles 7% more likely; and cousins 4% more likely.

Quantitative genetic modeling produced a significant genetic correlation, but no significant environmental correlation. Genetic correlation explained most, if not all, the covariance between ADHD and any autoimmune disease.

The authors concluded, "ADHD was to some degree more strongly associated with maternal than paternal AD's, but by using aunts and uncles in a genetically informative study design, we demonstrate that this difference cannot be readily explained by AD-mediated maternal effects. Quantitative genetic modeling further indicates that the familial co-aggregation of ADHD and ADs is partly due to shared genetic factors. In addition, biological aunts, uncles, and cousins must be assumed to share the little environment with the index individuals, in further support of shared genetic factors underlying the familial co-aggregation. Moreover, both epidemiological and molecular genetics studies have demonstrated positive genetic correlations between ADHD and ADs, in agreement with our findings."

The authors emphasize that these results do not warrant screening for autoimmune diseases among asymptomatic individuals with ADHD.

Pharmacotherapy and ADHD in Adults with Autism Spectrum Disorder

How effective is pharmacotherapy of ADHD in adults with Autism Spectrum Disorder?

Autism spectrum disorder (ASD) is frequently comorbid with ADHD. Among adults with ADHD, as many as half are reported to also have ASD.

A Dutch team set out to answer two questions:


1)    Do adults with ADHD and comorbid ASD experience less effectiveness in pharmacological treatment for ADHD than adults with only ADHD
2)    Do adults with ADHD and comorbid ASD experience different or more severe side effects of pharmacological treatment for ADHD than adults with only ADHD, as measured in side effect scores, blood pressure, heart rate, and weight?

This was a retrospective study, using well-documented medical records, of the effects of drug treatment with methylphenidate (MPH), dexamphetamine (DEX), atomoxetine (ATX), bupropion, or modafinil.

The researchers compared 60 adults with comorbid ASD and ADHD to 226 adults with only ADHD. ADHD symptoms were scored using the Conner's ADHD Rating Scale: Self Report-Short Version (CAA RS: S-S). Side effects of ADHD medication were measured using either a 13-item or 20-item checklist with 4-point scales for item response. Researchers also tracked changes in body weight, blood pressure, and heart rate.

Following treatment, ADHD symptoms among the comorbid group declined by a quarter, and among the ADHD-only group by almost a third. There was no significant difference between men and women. Controlling for age, gender, and ADHD subtype, a comorbid diagnosis of ASD also did not significantly affect ADHD symptom reduction.

Turning to side effects, in the ADHD+ASD group, there were significant increases in decreased appetite and weight loss, and decreases in agitation, anxiety, and sadness/unhappiness. In the ADHD-only group, there were significant increases in decreased appetite, weight loss, and dry mouth, and decreases in sleeping disorder, nervousness, agitation, anxiety, and sadness/unhappiness. Yet there were no significant differences between the two groups. Side effects increased and decreased similarly in both. Likewise, there were no significant differences between the groups in changes in heart rate and blood pressure. The only significant difference in medication dosage was for bupropion, which was higher in the ADHD+ASD group, though without any sign of the difference in side effects.

The authors concluded that this retrospective study "showed pharmacological treatment of adults with diagnoses of ADHD and ASD to be just as successful as the pharmacological treatment of adults with only ADHD," but cautioned that "randomized controlled trial should be conducted to evaluate the effectiveness and possible side effects of pharmacological treatment for ADHD in patients with ASD more reliably."

ADHD and Adulthood Unhappiness

ADHD is Associated with Significantly Higher Probability of Unhappiness in Adults

An international team of researchers sets out to measure the association between ADHD symptoms and self-evaluations of happiness among adults in the general population of the U.K. A nationally representative sample of 7,274 adults was asked to rate their happiness on a three-point scale. They also used the Adult ADHD Self-Report Scale (ASRS) Screener to assess ADHD symptom levels.
Higher ADHD symptom levels were found to be inversely associated with self-assessments of happiness. Adults with the lowest ADHD symptoms (0-9 on theaters) were roughly twice as likely to report being happy as those scoring10-13, five times as happy as those scoring 14-17, and ten times as happy as those with the highest ADHD symptom scores (18-24). These results were highly significant.
That did not mean that most adults with high ADHD symptom scores were unhappy. Even among those with the highest ADHD symptom scores (18-24), a majority (58 percent) reported being either "fairly happy" or "very happy." Butonly11 a percent of that group reported being "very happy," as opposed to 44 percent of those scoring the lowest on ADHD symptoms.
While the association is clear and strong, establishing causation is trickier. As the authors acknowledge, "as the symptoms associated with ADHD are similar to, and sometimes overlap, with those that are commonly observed in individuals with other psychiatric disorders ... a screening instrument to identify ADHD symptoms may have had limited power to distinguish 'pure' ADHD and cases with ADHD symptoms related to other psychiatric disorders." Emotional instability and anxiety disorder each mediated more than a third of the association between ADHD and unhappiness, and depression almost a third. These could have been brought about by ADHD and could also have been produced by other psychiatric disorders.  Because the ASRS is not a diagnostic instrument, the authors concluded that "the results of this study should be considered provisional, until if, and when, they are replicated in those with a clinical diagnosis of ADHD with and without comorbid disorders."

ADHD, High Blood Pressure, and Diabetes

ADHDIs A Risk Factor For Type Two Diabetes And High Blood Pressure, As Well As Other Psychiatric Disorders

All Swedish residents have their health records tracked through unique personal identity numbers. That makes it possible to identify psychiatric and medical disorders with great accuracy across an entire population, in this case encompassing more than five and a half million adults aged 18 to 64. A subgroup of more than 1.6 million persons between the ages of 50 and 64 enabled a separate examination of disorders in older adults.
Slightly over one percent of the entire population (about 61,000) was diagnosed with ADHD at some point as an adult. Individuals with ADHD were nine times as likely to suffer from depression as were adults not diagnosed with ADHD. They were also more than nine times as likely to suffer from anxiety or a substance use disorder, and twenty times as likely to be diagnosed with bipolar disorder.  These findings are very consistent with reports from clinical samples in the USA and Europe.
Adults with ADHD also had elevated levels of metabolic disorders, being almost twice as likely to have high blood pressure, and more than twice as likely to have type 2 diabetes. Persons with ADHD but without psychiatric comorbidities were also almost twice as likely to have high blood pressure, and more than twice as likely to have type2 diabetes.
Similar patterns were found in men and women with ADHD, although comorbid depression, bipolar disorder, and anxiety were moderately more prevalent in females than in males, whereas substance use disorder, type 2 diabetes, and hypertension were more prevalent in males than in females.
ADHD was less than a third as prevalent in the over-50 population as in the general adult population. Nevertheless, individuals in this older group with ADHD were twelve times as likely to suffer from depression, anxiety, or substance use disorders, and more than 23 times as likely to be diagnosed with bipolar disorder as their non-ADHD peers. They were also 63% more likely to have high blood pressure, and 72% more likely to have type 2 diabetes.
The authors noted, "Although the mechanisms underlying these associations are not well understood, we know from both epidemiologic and molecular genetic studies that a shared genetic predisposition might account for the coexistence of two or more psychiatric conditions. In addition, individuals with ADHD may experience increased difficulties as the demands of life increase, which may contribute to the development of depression and anxiety." As for associations with hypertension and type 2 diabetes, these "might reflect health risk behaviors among adult patients with comorbid ADHD in addition to a shared biological substrate. As others have noted, inattention, disinhibition, and disorganization associated with ADHD could make it difficult for patients to adhere to treatment regimens for metabolic disorders." They concluded that "Clinicians should remain vigilant for a wide range of psychiatric and metabolic problems in ADHD affected adults of all ages and both sexes."

Associations between ADHD and autoimmune diseases

Associations between ADHD and autoimmune diseases

A Norwegian team based at the University of Bergen recently performed a population study using the country's detailed national health registries. With records from more than two and a half million Norwegians, the team examined what, if any, associations could be found between ADHD and nine autoimmune diseases: ankylosing spondylitis, Crohn's disease, iridocyclitis, multiple sclerosis, psoriasis, rheumatoid arthritis, systemic lupus erythematosus, type 1 diabetes, and ulcerative colitis.

After adjusting for age and maternal education, the team found no association between ADHD and five of the nine autoimmune disorders: type 1 diabetes, rheumatoid arthritis, iridocyclitis, systemic lupus erythematosus, and multiple sclerosis. In the case of ankylosing spondylitis, it found no association with males with ADHD, but a negative association with females. Females with ADHD were less likely to have ankylosing spondylitis. The adjusted odds ratio (AOR) was 0.56 (95% CI 0.32-0.96).

Positive associations were found for only three autoimmune diseases. The strongest was for psoriasis, with adjusted odds ratios of 1.6(95% CI 1.5-1.7) for females and 1.3 (95% CI 1.2-1.4) for males. When further adjusted for education, smoking, and body mass index (BMI), however, the adjusted odds ratio for females with ADHD dropped to 1.3 (95% CI 1.0-1.6).

The second-strongest association was with Crohn's disease. But here it was only among women. The odds ratio, in this case, was 1.4 (95% CI 1.2-1.8). Males with ADHD were less likely to have Crohn's disease, with an odds ratio of 0.71 (95% CI 0.54-0.92).

Finally, females with ADHD were slightly more likely to have ulcerative colitis, with a barely significant odds ratio of 1.3 (95% CI 1.1-1.5), while no such association was found for males with ADHD, whose odds ratio was a statistically non-significant 0.9.

Given the large sample size of over two and a half million, this is no underpowered study. It found no association between ADHD and the generic category of autoimmune disorders. Furthermore, it is a stretch to argue that there are any clear and clinically meaningful links between ADHD and any of the specific disorders that were analyzed in this study. The small and often opposite effect sizes may simply reflect limitations with the data (presumed autoimmune disorders were identified based on drugs prescribed), or other unidentified confounding factors.

The State of the Art on Identifying and Treating Persons with Comorbid ADHD and Substance Use Disorders

The State of the Art on Identifying and Treating Persons with Comorbid ADHD and Substance Use Disorders

An international group of twelve experts recently published a consensus report examining the state of the evidence and offering recommendations to guide the screening, diagnosis, and treatment of individuals with ADHD-SUD comorbidity.[1]

In a clear sign that we are still in the early stages of understanding this relationship, five of the thirteen recommendations received the lowest recommendation grade (D), eight received the next-lowest (C), and none received the highest (A and B). The lower grades reflected the absence of the highest level of evidence, obtained from meta-analyses or systematic reviews of relevant randomized controlled trials (RCTs).

Nevertheless, with these limitations in mind, the experts agreed on the following points:

Diagnosis

  •  The strongest recommendation, the only one based on a 2+ level of evidence (well-conducted case-control or cohort studies with allowing risk of confounding or bias and a moderate probability that the relationship is causal) is that the "Short Version of the Adult ADHD Self-Report Scale (ASRS-SV) screener is currently the most widely used and investigated screening tool in individuals with ADHD and comorbid SUD, with good sensitivity and specificity across studies."
  • Two other recommendations were graded C: The diagnostic process should include current and past substance abuse, and seek to involve partners and relatives in evaluating symptoms and functional impairments.
  • Four recommendations got the lowest grade, D. The experts suggested starting the diagnostic process as soon as possible and focusing on drug- and alcohol-free periods in the patient's life during history taking. They also recommended that physicians and clinical psychologists should only make diagnoses if they have extensive training in diagnosing ADHD, as well as experience with adults with ADHD and with addiction care, and that they should consider treating adults with sufficiently severe ADHD symptoms.

Treatmen

  •  In general, evidence was stronger in this area, and only one of the six recommendations was graded D. The other five recommendations were graded C, with the highest level of evidence being 2(cohort or case and control studies with undetermined risk of bias), although in three cases it was level 3 (non-analytical studies, such as case reports and case series).
  • The grade D recommendation was to always consider a combination of psychotherapy and pharmacotherapy.

The grade C recommendations included considering adequate medical treatment of both ADHD and SUD; integrating ADHD treatment with SUD treatment as soon as possible;

Everything You Need to Know About ADHD

Everything You Need to Know About ADHD

You've heard all sorts of misinformation about Attention-Deficit/Hyperactivity Disorder(ADHD), whether from friends, the internet, or uninformed press articles:

"ADHD is not real."

"Pharmaceutical companies invented ADHD to make money."

"I'm just a little ADD."

"Natural solutions are the best for ADHD treatment."

ADHD symptoms were first described in the late 1700s, primarily among hyperactive boys. It was described variously over 200 years as "fidgeting," "defects of moral control," "hyperkinetic reaction," "minimal brain damage" and eventually ADD (Attention Deficit Disorder) in the 1980s and ADHD today.

Because the natural tendency toward hyperactivity decreased with age, ADHD was originally thought to be a developmental disorder that disappeared in mid-to-late adolescence. When medicines were developed and used in ADHD treatment for young boys, physicians stopped prescribing them around mid-adolescence, because it was presumed the condition had been remediated. They were wrong. We know now that ADHD persists into adulthood for about two-thirds of ADHD youth.

ADHD was not widely recognized in girls until the mid-1990s when it became clear that girls with ADHD were less disruptive than boys with ADHD and were not being appropriately diagnosed. Girls with ADHD show less of the physical hyperactivity of boys, but suffer from "dreaminess," "lack of focus" and "lack of follow-through."

It was also in the 1990s that ADHD' pervasive comorbidity with depression, anxiety, mood, and autism spectrum disorders was established. At the same time, researchers were beginning to describe deficits in executive functioning and emotional dysregulation that became targets of substantial research in the 21st century.

Even with the 1990s recognition that ADHD is a lifetime disorder, equally present (in different forms) in both men and women, medical schools and continuing medical education courses (required for realizing sure of health professionals) have only begun to teach the most up-to-date evidence-based knowledge to the medical community. There still is much misinformation and a lack of knowledge among primary care professionals and the public.

ADHD Throughout the Lifespan
Most cases of ADHD start in Otero before the child is born. As a fetus, the future ADHD person carries versions of genes that increase the risk for the disorder. At the same time, they are exposed to toxic environments. These genetic and environmental risks change the developing brain, setting the foundation for the future emergence of ADHD.

In preschool, early signs of ADHD are seen in emotional lability, hyperactivity, disinhibited behavior and speech, and language and coordination problems. The full-blown ADHD syndrome typically occurs in early childhood, but can be delayed until adolescence. In some cases, the future ADHD person is temporarily protected from the emergence of ADHD due to factors such as high intelligence or especially supportive family and/or school environments. But, as the challenges of life increase, this social, emotional, and intellectual scaffolding is no longer sufficient to control the emergence of disabling ADHD symptoms.

Throughout childhood and adolescence, the emergence and persistence of the disorder are regulated by additional environmental risk factors such as family chaos, as well as the age-dependent expression of risk genes that exert different effects at different stages of development. During adolescence, most cases of ADHD persist and by the teenage years, many youths with ADHD have onset with a mood, anxiety, or substance use disorder. Indeed, parents and clinicians need to monitor ADHD youth for early signs of these disorders. Prompt treatment can prevent years of distress and disability.

By adulthood, the number of comorbid conditions increases, including obesity, which likely impacts future medical outcomes. Emerging data shows people with ADHD to be at increased risk for hypertension and diabetes. ADHD adults tend to be very inattentive but show fewer symptoms of hyperactivity and impulsivity. They remain at risk for substance abuse, low self-esteem, injuries due to accidents, occupational failure, and social disability, especially if they are not treated for the disorder.

Seven Important Concepts About ADHD


There are approximately 10 million U.S. adults with ADHD, 9 million of whom are undiagnosed. But with diligent research by the medical profession, we have learned seven important concepts about ADHD:
1.    ADHD has been documented worldwide in 5% of the population.
2.    Sixty-seven percent of ADHD children grow into ADHD adults and seniors. ADHD is heritable, runs in families, and is impacted by the physical environment and familial lifestyle.
3.    In youth, rates of ADHD are higher in males than females as males, but these rates even out by adulthood.
4.    ADHD coexists and is often masked by several other disorders: anxiety, depression, spectrum bipolar and autism disorder, substance abuse, alcoholism, obesity, risky behaviors, disorganized lives, working memory deficits, and significant executive dysfunctions that affect personal, social, and work success.
5.    ADHD medications(stimulants and non-stimulants) are the most effective treatments for ADHD symptoms. Psychological support/training designed for ADHD, and lifestyle modifications, are important adjuncts to medicine.
6.    ADHD costs the U.S. economy more than $100 million annually in lost productivity, accidents, hospitalizations with comorbidities, and family and professional support for ADHD patients.
7.    ADHD is diagnosable and safely treatable in trained primary care practices.

How do you know if you or someone you love has ADHD? Evaluate your life against the seven concepts above. Then get screened and diagnosed by a health care professional. The diagnosis of ADHD should be done only by a licensed clinician who has been trained in ADHD. That clinician should have one goal in mind: to plan a safe and effective course of evidence-based treatment.

When diagnosing adults, it is also useful to collect information from a significant other, which can be a parent for young adults or a spouse for older adults. But when such individuals are not available, diagnosing ADHD based on the patient's self-report is valid. Just remember that personal, work, and family lives are improved with treatment. Research and technology related to ADHD improve all the time.

ADHD in Adults is a great resource for anyone interested in learning more about ADHD, with evidence-based information and education for both healthcare professionals and the public. The website also features a new ADHD screener for predicting the presence of ADHD in adults.

Is Pharmacotherapy Effective for ADHD Adults with Autism Spectrum Disorder?

How effective is pharmacotherapy of ADHD in adults with Autism Spectrum Disorder?

The team of researchers found that pharmacological treatment of adults with diagnoses of ADHD and ASD seem to be just as successful as the pharmacological treatment of adults with only ADHD.

Autism spectrum disorder (ASD) is frequently comorbid with ADHD. Among adults with ADHD, as many as half are reported to also have ASD.

A Dutch team set out to answer two questions:

  • Do adults with ADHD and comorbid ASD experience less effectiveness of pharmacological treatment for ADHD than adults with only ADHD?
  • Do adults with ADHD and comorbid ASD experience different or more severe side effects of pharmacological treatment for ADHD than adults with only ADHD, as measured in side-effect scores, blood pressure, heart rate, and weight?

This was a retrospective study, using well-documented medical records, of the effects of drug treatment with methylphenidate (MPH), dexamphetamine (DEX), atomoxetine (ATX), bupropion, or modafinil.

The researchers compared 60 adults with comorbid ASD and ADHD to 226 adults with only ADHD. ADHD symptoms were scored using the Conner's ADHD Rating Scale: Self Report-Short Version (CAARS: S-S). Side effects of ADHD medication were measured using either a 13-item or 20-item checklist with 4-point scales for item response. Researchers also tracked changes in body weight, blood pressure, and heart rate.

Following treatment, ADHD symptoms among the comorbid group declined by a quarter, and among the ADHD-only group by almost a third. There was no significant difference between men and women. Controlling for age, gender, and ADHD subtype, a comorbid diagnosis of ASD also did not significantly affect ADHD symptom reduction.

Turning to side effects, in the ADHD+ASD group, there were significant increases in decreased appetite and weight loss, and decreases in agitation, anxiety, and sadness/unhappiness. In the ADHD-only group, there were significant increases in decreased appetite, weight loss, and dry mouth, and decreases in sleeping disorder, nervousness, agitation, anxiety, and sadness/unhappiness. Yet there were no significant differences between the two groups. Side effects increased and decreased similarly in both. Likewise, there were no significant differences between the groups in changes in heart rate and blood pressure. The only significant difference in medication dosage was for bupropion, which was higher in the ADHD+ASD group, though without any sign of difference in side effects.

The authors concluded that this retrospective study showed pharmacological treatment of adults with diagnoses of ADHD and ASD to be just as successful as the pharmacological treatment of adults with only ADHD, but cautioned that a randomized controlled trial should be conducted to evaluate the effectiveness and possible side effects of pharmacological treatment for ADHD in patients with ASD more reliably.
