title: [Studies on the psychopathology of adults with 4-5 c/s EEG rhythm (author's transl)].
abstract: Nineteen subjects (10 males and 9 females, aged between 18 and 61 years) with an occipital 4-5 c/s EEG rhythm were tested using a multidimensional psychological test program. The program consisted of the IST of Amthauer, the Raven Test, the German version of the MMPI ("MMPI Saarbrücken"), the Cattell 16-PF-questionnaire, Brickenkamp's d2-Test, and a test battery for psychomotor impairment. A group of normal persons with a regular alpha EEG, matched according to sex and age, was used to provide test norms for the 4-5 c/s EEG group. No difference in intelligence was found, but statistically significant differences were found in some personality traits in the MMPI and the 16-PF-questionnaire. Taking into consideration that the 4-5 c/s EEG group of the study is a subjective sample not randomly selected, this study showed that the male subjects with a 4-5 c/s rhythm as more sensitive, more tender and gentle, more anxious, and less tolerant of stress when compared with the control group; in terms of sex-specific personality traits, they tend to show more female features. Furthermore, the clinical observations of the psychological test date are discussed, i.e., that the subjects with 4-5 c/s rhythms suffer more frequently from functional somatic complaints (observed in 13 cases: 9 with neurovegetative disturbances, 4 with psychosomatic diseases) and/or show psychopathological features (observed in 12 cases: 8 with abnormal personality traits, 4 with neurotic personality development).
