Forty-one patients admitted to an inpatient epilepsy unit for intracta
ble seizures were evaluated for the presence of Axis I and Axis II dia
gnoses and for a history of trauma by use of a structured clinical int
erview. Both the interviewer and the patient were blind to the seizure
diagnosis. Following video and electroencephalographic evaluation, 27
patients were diagnosed with epileptic seizures, and 14 had psychogen
ic seizures. The history of Axis I and Axis II disorders did not disti
nguish the two groups Of patients. A history of trauma was significant
ly more likely in the patients with psychogenic seizures. The experien
ce of trauma appears to be an important factor in the development of p
sychogenic seizures. Sexual trauma alone, however, was not significant
ly associated with psychogenic seizures.
