Neural Correlates of Sluggish Cognitive Tempo: Biological Evidence of a Distinct Clinical Entity?

Attention-deficit/hyperactivity disorder (ADHD) is a heterogeneous disorder encompassing a wide array of clinical presentations, levels of impairment, etiologies, and neurobiological correlates. Despite this well-known heterogeneity, most research into the pathophysiology of ADHD has relied upon comparisons of typically developing youth relative to those with the disorder (or perhaps further stratifying by DSM-defined ADHD subtypes). Though informative, this approach assumes a level of pathophysiological homogeneity that belies the large and growing body of literature underscoring diverse neurobiological and neuropsychological profiles subsumed under the umbrella of this complex syndrome.
