The subjects included all consecutive admissions to an adult, acute-treatment university psychiatric service for 22 months ending May 1976. Twenty-minute scalp-recorded resting EEGs were obtained in all cooperative patients, usually with sleep. The International 10-20 system and unipolar and bipolar montages were used. EEGs were read by an electroencephalographer (R.A.) who was blind to any information that could identify the patient or indicate psychotropic drug status. All records were classified as normal, borderline, or abnormal, according to the criteria of Gibbs and Gibbs (2). Borderline and abnormal records were subsequently combined for anal-

The mean lithium dosage for the combined therapy group was 143 1 mg/day (range =900- 1800 mg/day), with a mean serum lithium level of 0.94 mEq/liter (SD=0.32). The mean haloperidol dosages were 39 mg/ day (range=20-.60 mg/day) for the combined-treatment group and 38 mg/day for the neuroleptic-only group. There was no significant difference in the distribution of EEG abnormalities for the four groups or for the 3 drug treatment groups considered alone (see table 1).
