Abstract:
A quantitative electroencephalographic technique for testing and assessing individuals for Attention Deficit Hyperactivity Disorder (ADHD), comprising the steps of:a) placing an electrode at a single cranial site of an individual to be tested for ADHD;b) obtaining digitized EEG data in two frequency bands:theta (4-8 Hz) and beta (13-21 Hz);c) obtaining a baseline neurometric index comprising a ratio of the electrophysiological power recorded in the theta band divided by the electrophysiological power recorded in the beta band obtained in step (b);d) thereafter, testing said individual in accordance with steps (b) and (c) under conditions requiring attentive behavior;e) obtaining an overall Attentional Index for said individual which represents the average theta/beta power ratio calculated during said baseline and said attentive behavior tasks; andf) comparing said Attentional Index obtained in step (e) to a normative database of individuals without ADHD to determine presence and severity of said individual's ADHD.
