Irritability appears to be a potent independent predictor of increased risk for suicidality in children and adolescents with ADHD. While there is ample evidence that ADHD is associated with increased suicidality, a recent study involving 1,516 youths aged 6-17 years attending an outpatient ADHD clinic demonstrated that this increased risk is mediated by depression and irritability in roughly equal measures. Moreover, upon controlling for those two factors in a multivariate analysis, ADHD symptoms, per se, had no direct effect on risk of suicidality as defined by suidical ideation, attempts, or self-harm.

The clinical take-home message is that assessing irritability, as well as depression, may bolster an estimate of suicidality and help in managing suicidal risk in ADHD. The study included separate parent- and teacher-structured reports of the youths ADHD symptoms, suicidality, depression, irritability, and anxiety. Parents reported suicidality in 12.1% of the pediatric patients, significantly higher than the 3.8% rate reported by teachers.

In multivariate analyses, parent-reported depression accounted for 39.1% of the association between ADHD symptoms and suicidality, while irritability symptoms mediated 36.8% of the total effect. In the teachers’ reports, depression and irritability symptoms accounted for 45.3% and 38.4% of the association. Anxiety symptoms mediated 19% of the relationship between ADHD and suicidality by parental report but had no significant impact on the association according to teacher report in the recently published study.

Researchers noted that, in the DSM-5, irritability cuts across diagnostic categories. It is not only a core dimension of ADHD, but of the other externalizing disorders – conduct disorder and oppositional defiant disorder – as well, and also of neurodevelopmental, internalizing, and stress-related disorders.

Most suicidal youths are attempting to cope with mental disorders. The most prevalent of these are major depressive disorder and dysthymia, followed by externalizing disorders. And among the externalizing disorders, conduct disorder stands out in terms of the magnitude of associated suicidality risk.

In addition to depression, irritability symptoms, and conduct problems, other risk factors that should be part of a suicidality assessment in children and adolescents with ADHD include substance use, anxiety, poor family support, and bullying and/or being bullied.
