Currently, ADHD is subdivided into three diagnostic subtypes, defined by predominance in inattention, hyper-activity, and impulsivity, or as the combined type that includes both inattention and hyperactivity/impulsivity.
Pharmacological treatments for ADHD enhance cate-cholaminergic neurotransmission. This repeated observation, combined with neuroimaging evidence strongly implicate fronto-striatal and fronto-cerebellar circuits in deficits affecting behavioral organization and the ability to predict events and behavioral outcomes; a further deficit in the fronto-amygdalar loop that assigns emotional significance to predicted and detected events is also hypothesized (Swanson et al. 2007). However, no differences in medication response have been reported among the three subtypes.
