EFFECTS OF CEREBRAL ELECTRICAL-STIMULATION ON ALCOHOLISM - A PILOT-STUDY

Cerebral electrical stimulation (CES), born from research on electroan esthesia in the seventies, consists of the application of a pulsating current of small intensity (usually less than 1 mA, and below the thre shold of perception) through the skull, e.g., in daily 30-min sessions . Claims of biological effectiveness (neurochemical, hormonal and EEG changes, naloxone-reversible analgesia in rats, etc.) and of clinical effectiveness (anxiety, depression, cognitive functions in alcoholics) have often relied on poorly controlled data. A recent controlled stud y in the treatment of opiate withdrawal has been positive. The present double-blind controlled study compares active CES with sham stimulati on in 64 alcohol-dependent males. Over 4 weeks, both treatment groups improved significantly in most aspects. In the active treatment group additional significant improvement was observed in week-end alcohol co nsumption, and in two psychological measures: depression and stress sy mptoms index, but not in general drinking behavior.
