While romantic relationships can bring contentment and stability to adults with psychological disorders, conflict in such relationships adds incremental risk for developing depressive, anxiety, and substance use disorders. Moreover, persons with ADHD are more prone to such conflict than those without ADHD.
ADHD symptoms are negatively associated with satisfaction in dating relationships. One study found that female college students, blind to ADHD status, were less interested in male students with ADHD-Inattentive presentation than peers without ADHD. Another study found that college students who self-reported significant inattentive and hyperactive-impulsive symptoms also reported lower romantic relationship satisfaction than students not reporting such symptoms. A third study likewise found an inverse association between college student-reported inattentive symptoms and romantic relationship satisfaction, although it found no such association for self-reported hyperactive/impulsive symptoms.
This in turn has behavioral implications. One study found that college students with clinically elevated symptoms of inattention, hyperactivity/impulsivity, or both, reported higher levels of hostile conflict behavior with their partners than students without clinically elevated symptoms. Another study placed young couples through conflict resolutions. Couples in which one partner had ADHD demonstrated more negative and less positive conflict resolution behavior, and reported lower relational satisfaction, than couples in which neither partner had an ADHD diagnosis.
Worse yet, ADHD is a risk factor for dating violence. Two studies found that young adult males diagnosed with ADHD as children self-reported engaging in more frequent verbal and physical intimate partner violence than did their normally developing peers. Two more studies reported that men and women diagnosed with ADHD as children were at greater risk of becoming victims of such violence.
Adults with ADHD are also more likely to engage in risky sexual behavior. On average, they initiate sexual intercourse between one and two years earlier. They tend to have more partners and to make less frequent use of contraception than non-ADHD peers. As a result, adults with ADHD are also more likely to have unplanned pregnancies and to acquire sexually transmitted diseases.
Given these findings, it is hardly surprising that adults with ADHD report lower marital satisfaction than their normally developing peers. One study reported that 24 out of every 25 spouses of adults with ADHD felt their partner's symptoms interfered with their functioning in one or more domains, including general household organization/time management, child-rearing, and communication. Most studies have found that extramarital affairs, separation, and divorce are more frequent among couples in which one partner has ADHD.
ADHD is known to be highly heritable. That introduces further challenges. One study found that parents of children with ADHD are twice as likely to divorce by the time their child is eight years older than parents of children without ADHD. Another study found that disruptive child behavior is linked to parents arguing among themselves. This pattern was especially pronounced with parents who themselves had elevated ADHD symptoms. However, another study found that when both parents had ADHD symptoms, they were less likely to argue than when only one parent had such symptoms, or when neither did.
The authors note that there have been few longitudinal studies of the relationship to the behavior of adults with ADHD and that these are badly needed. This would help to understand how alcohol consumption relates to the development of relationship problems, for example.
Second, they point out that little is known about which subpopulations in the large population of adults with ADHD may be especially at risk for romantic relationship problems. Gender and history of maltreatment do not appear to be significant influences, but there is some evidence that alcohol and drug abuse may be a factor, as well as underachievement in adolescence. Moreover, the literature to date has focused on heterosexual Caucasian couples. There is a need for research with larger, more heterogeneous, population samples, and in particular with racial/ethnic minorities and LGBTQ+ adults.
Third, they suggest a need for further research on mediators between ADHD and romantic relationship problems. There are reasons to suspect a key role for emotion dysregulation and deficits in inhibitory controls. But studies to date have relied on self-reporting, which introduces respondent bias. Future studies should obtain ratings of ADHD and relationship functioning from other informants. There is also a need for studies focusing not just on younger adults, but also on older ones. Another critical need is for clinical trials testing the effectiveness of different interventions aiming to improve romantic relationship functioning.
The authors conclude, "Given that success in romantic relationships is considered by many to be a major developmental task and that ADHD persists for many affected individuals into adulthood, research on romantic adjustment of affected adults is surprisingly limited. The majority of existent published research points, however, to a robust association between ADHD and negative outcomes such as lower satisfaction in relationships, maladaptive conflict resolution styles, higher rates of relational dissolution, and behavioral issues such as unsafe sex and IPV."

Prevalence of cannabis use among pregnant women is on the rise with the spread of legalization. The most frequently reported reasons for use are to relieve stress or anxiety, nausea or vomiting, pain, and for recreation.
Given that the primary psychoactive ingredient of cannabis, ∆9-tetrahydrocannabinol (THC) is a small fat-soluble molecule that can easily cross the placenta, an Israeli-U.S. research team conducted a systematic search of the peer-reviewed medical literature for studies exploring possible neuropsychiatric effects on offspring.
They included not only studies evaluating likelihood of ADHD, but also autism spectrum disorder, anxiety, depression, and psychotic symptoms. For each of these, adjustment was made for known confounding variables.
With that adjustment, meta-analysis of six studies with a total of over half a million (503,661) participants reported a 13% increase in the odds of ADHD in offspring of mothers using cannabis during pregnancy compared with offspring of mothers not using cannabis while pregnant.
That is generally considered a small effect size increase in risk. But there are multiple reasons to question even this minimal finding:
Meta-analysis of two studies with a total of 741 individuals reported a 20% increase in offspring use of cannabis among mothers who used cannabis during pregnancy, but once again this was subject to methodological shortcomings:
Some studies have suggested a link between cannabis and psychotic symptoms. But meta-analysis of four studies combining over nineteen thousand persons found no significant association between maternal cannabis use during pregnancy and offspring psychotic symptoms.
Many studies have pointed to commonalities in the etiology of ADHD and autism spectrum disorder (ASD). Yet meta-analysis of five studies encompassing over half a million participants found absolutely no association between maternal prenatal cannabis use and ASD.
The remaining meta-analyses also reported no association with depression or anxiety.
With the caution that absence of evidence is not the same as evidence of absence, it is by no means clear from what is presently known that prenatal cannabis exposure has any significant neuropsychiatric effects on offspring. And if further research finds any effects, they are likely to be minor.
Dasotraline is a serotonin-norepinephrine-dopamine reuptake inhibitor (SNDRI) that had been under development by Sunovion for treating ADHD and binge eating disorder.
An Indian research team conducted a systematic search of the peer-reviewed medical literature to perform meta-analyses of the quantitative outcomes of clinical trials.
Meta-analysis of five double-blinded randomized clinical trials (RCTs) with a combined total of 1,498 participants reported a small-to-medium effect size reduction in ADHD symptoms in patients given dasotraline as opposed to those given placebo.
There were, however, strong indications of publication bias. Using the trim-and-fill procedure to correct for that bias yielded a small effect size reduction in ADHD symptoms in patients given dasotraline compared with those given placebo.
Insomnia were more than four times more frequent among patients given dasotraline than among those given placebo. There was no evidence of the frequency of insomnia being dose-dependent.
Similarly, patients given dasotraline were more than four times more likely to report decreased appetite than those receiving placebo. In this case, however, the effect was clearly dose-dependent, rising from 3x for 2mg to 4x for 4mg to 5x for 6mg and almost 8x for 8mg.
The authors concluded, “dasotraline can reduce the core symptoms of ADHD, that is, hyperactivity/impulsivity and inattentiveness, leading to an overall improvement of ADHD compared to placebo. Dasotraline can also improve clinician-determined patients’ global functioning compared to the placebo. The most common adverse drug reactions related to dasotraline were insomnia and decreased appetite. However, to fill the knowledge gap, multicentric randomized active-controlled clinical trials are warranted in this domain for a successful translation into clinical practice.”
Weighing these less than impressive initial results against the cost of further RCTs, Sunovion withdrew its application for approval by the Food and Drug Administration, stating, “while Sunovion considers dasotraline to be a promising, novel treatment for binge eating disorder and ADHD, we believe that further clinical studies would be needed to support a regulatory approval for dasotraline in these indications.”
Children and adolescents with ADHD are known to have difficulties in relating to family members, peers, and teachers. Over the long run this can contribute to anxiety or even delinquency.
Several cognitive functions that allow individuals to process social information and interact with others contribute to shaping everyday social interactions. These include:
A European research team performed a systematic search of the peer-reviewed medical literature to conduct meta-analyses of ToM, Empathy, Facial and Non-Facial Emotion Recognition in children and adolescents with ADHD when compared to typical development. As a comparison measure, they also included Everyday Social Skills (using self, parent, teacher, or clinician questionnaires/interviews of social skills) as an outcome.
The search yielded 142 case-control studies (including dissertations) with a total of 16,283 participants.
Meta-analysis of 82 studies with a combined total of 10,770 participants found a very large effect size impairment in everyday social skills among children and adolescents with ADHD when compared with typically developing peers. Adjusting for covariates only strengthened the finding. There was no sign of publication bias.
This was mirrored in three out of five measures of social cognition:
The team concluded, “Our findings show that children and adolescents with ADHD have deficits in ToM, Facial Emotion Recognition, and Everyday Social Skills, three domains that warrant clinical attention.”
