What Are Common Comorbidities in ADHD?
In this article, Julie Sherman, PhD and Jay Tarnow, MD briefly discuss the latest research findings on ADHD.
ADHD occurs in 3% to 5% of the US population.1 The risk for comorbidity is high, and the presence of comorbid disorders warrants special consideration in the treatment of patients with ADHD. For example, a comorbid diagnosis of ADHD and depression occurs in approximately 20% to 30% of patients, and ADHD and anxiety in more than 25% of patients.1
Comorbidity rates in adults are equal to or higher than those in children, although very few studies have examined these patterns over time in adults. A longitudinal study by
Some researchers propose that comorbid bipolar disorder (BD) and ADHD should form a separate clinical phenotype of BD. A
ADHD is associated with abnormalities in the frontal lobes. It makes sense that any neurological disorder that originates in these regions would increase the risk for ADHD. Zhang and colleagues3 evaluated children with frontal lobe epilepsy for the prevalence of ADHD: 89.4% of the children with an abnormal EEG had coexisting ADHD compared with only 25% of children with normal EEG readings. The authors concluded that frontal lobe epilepsy is strongly linked with the occurrence of ADHD, and this occurrence is even greater for individuals with an abnormal EEG.
It is important to treat all comorbidities. Because individuals with comorbid psychiatric disorders experience greater cognitive, social, and psychological impairments, however, mental health professionals are encouraged to screen for early detection and intervention.
