Abstract

Based on degree of premorbid asociality, hospitalized schizophrenics were divided into process and reactive subgroups which are statistically equated on the variables of intelligence, chronicity, degree of drug-free state at time of EEG, and total amount of sleep EEG recording obtained. The B-mitten EEG pattern is significantly related to reactive schizophrenia for all subjects combined and for males and females considered separately. Among nonschizophrenic patients the relationship of mitten patterns to reactive premorbid history did not occur. There were no differences between reactive and process schizophrenics in terms of abnormal EEGs when mitten patterns were omitted from consideration. Reliability of diagnosis, process-reactive categorization, and interpretation of the mitten pattern was assessed and found to be highly significant.
