Dual Personality Associated With Epilepsy

Arch Neurol. 1986;43(5):471-474. doi:10.1001/archneur.1986.00520050051021

• Two individuals with well-defined seizure problems developed dual personalities. One personality was irritable and hostile, the other placid; in each case, a major seizure preceded the shift from the former to the latter. Each personality was amnesic for the other. The incidence of seizures in patients with multiple personality disorder is higher than expected, and these cases demonstrate a direct relationship.
