Adult attention-deficit hyperactivity disorder and bipolar disorder

Increasing attention is being paid to the concept of attention-deficit hyperactivity disorder (ADHD) in adults, in concord with evidence that suggests a proportion of children with ADHD continue to manifest symptoms into adulthood. Attention-deficit hyperactivity disorder has some symptoms in common with hypomania, and can co-occur with bipolar disorder. The diagnosis and management of ADHD in adults with bipolar disorder can be complicated, owing to challenges resulting from symptom overlap, questions of diagnostic validity and a paucity of empirical evidence to guide treatment. This article addresses comorbid ADHD and bipolar disorder, and provides practical suggestions for diagnosis and management.
