Abstract

The objective of the current study is to identify the impact of methylphenidate (MPH) on autonomic functioning within an emotional context among youth with attention-deficit/hyperactivity disorder (ADHD; Aim 1a), consider for MPH dosage (Aim 1b), and heterogenous response to MPH using existing nosology (Aim 2). Further, the current study assesses autonomic functioning holistically to explain heterogenous behavioral disruptions (Aim 3). The current study utilizes psychophysiological and clinical data collected during a larger medication study. Results indicated that medication improved emotional functioning (indicated via psychophysiological indexes) among youth with ADHD to comparable levels as typically developing youth at the trait and state level. Further, youth with ADHD exhibit heterogenous autonomic functioning, which should be examined further for its utility to advance individualized treatment protocols.
