Personality Disorders Among Medically Refractory Epileptic Patients

DSM-III-R personality disorders were assessed in 52 medically refractory epileptic patients. Twenty-one percent of patients met threshold criteria for an Axis II disorder. Dependent and avoidant personality disorders were the most common diagnoses. Epileptic aura was positively correlated with the presence of personality disorders. These results support previous studies that have demonstrated an increased rate of dependency and social isolation in epileptic patients. This increase may be related to disrupted psychosocial functioning as a consequence of having epilepsy, to disrupted neuronal function in central nervous system structures as a consequence of repeated epileptiform discharge or to some combination of the two.
