alpha activity and slowing of the predominant alpha frequency [15,16]. CNS hyperarousal is indexed by high-frequency beta (19.5–39.8 Hz) activity, which has been used to predict relapse rates among abstinent alcoholics [14,17] and differentiate between abstinent and non-abstinent alcoholics [10]. Taken together, binge drinking and chronic alcoholism may represent two stages of the same phenomenon [18], such that similar CNS hyperarousal may be a biomarker for the binge drinking population.
