Claim One:
1. 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; and f) 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.
