There are several diagnostic criteria that must be met prior to the diagnosis of a particular mental health illness. Adult attention-deficit / hyperactivity disorder (ADHD) remains a clinically challenging entity to diagnose due to similar presentations in other disease states. The major criteria for ADHD diagnosis include: symptoms (inattention, easy distractibility, forgetfulness, impulsivity) that are rooted in childhood, functional impairment due to these symptoms in two of three domains (home, school, and/or work and social settings), and a causal relationship between ADHD and the symptoms.
ADHD is frequently diagnosed simultaneously with other co-morbid conditions including: dysthymia, depression, bipolar, anxiety and substance abuse disorders. Awareness of these diagnostic criteria is important for primary care physicians in order to provide the appropriate referrals for treatment.Reference: Katzman MA, Bilkey TS, Chokka PR, Fallu A, Klassen LJ.
