Abstract

This study investigated changes in the EEG of addicts initially on heroin as they progressed through the induction and maintenance phases of a methadone program. Spectral analysis of bipolar recordings revealed significant consistent differences only in the eyes-closed resting state. Patients under the influence of heroin showed large sharp peaks at 9-10 c/sec, particularly in the parieto-occipital recording. Methadone induction led either to marked reduction of this peak and widening of alpha band activity or to an increase in frequency of the alpha peak to 12 c/sec. After several months of methadone the alpha peak was still absent unless heroin abuse was present, a theta peak was present in three of four patients, and the alpha bandwidth remained broad. Changes in the theta band were more difficult to interpret.
