As part of a continuing clinical study of syncope, all patients referred because of an episode of loss of consciousness to the Neurology Clinic of a large military hospital serving a recruit training base were asked to perform a maximal Valsalva or Weber maneuver at the conclusion of a routine EEG examination. The technique employed has been previously described.1 To date 200 males of military age ranging from 17 to 44 years have participated in the project. Of these, 61 (30.5%) succumbed in syncopal episodes, which in 40 subjects were complicated by convulsive movements on 1 or more occasions. A total of 54 convulsive syncopes was studied in the EEG laboratory under conditions permitting methodical observation and appropriate physiological monitoring. An unusual opportunity was thus presented to characterize the salient features of anoxic convulsions in man. Observations made upon these episodes are presented in the hope of shedding some
