deficit/hyperactivity disorder that cause clinic ally significant distress or impairment in so-
cial, occupational, or other important areas of functioning predominate but do not meet the
full criteria for attention-deficit/hyperactivity disorder or any of the disorders in the neuro-
developmental disorders diagnostic class. The unspecified attention-deficit/hyperactivity
disorder category is used in situations in which the clinician chooses not to specify the rea-

neurodevelopmental disorder, and includes presentations in which there is insufficient in-
