title: The association of multiple personality and temporolimbic epilepsy. Intracarotid amobarbital test observations.
abstract: OBJECTIVE
  What is the relationship of "multiple personality disorder" in patients with temporolimbic epilepsy to certain types of hemispheric interaction?
  
  
  METHODS
  Case series.
  
  
  METHODS
  Tertiary care referral center.
  
  
  METHODS
  Two patients with temporolimbic epilepsy considered to be surgical candidates referred for the intracarotid amobarbital sodium procedure (IAP). Each individual had presented with different "personalities" in a characteristic temporal relationship to their seizures.
  
  
  METHODS
  Intracarotid amobarbital sodium procedure, Wada test, and electroencephalogram.
  
  
  METHODS
  Behavioral observations made during the performance of the IAP.
  
  
  RESULTS
  During the IAP, each patient's peri-ictal "personality" changes were precisely replicated. No seizure activity was noted during the IAPs.
  
  
  CONCLUSIONS
  These observations suggest that the association of multiple personality and temporolimbic epilepsy is not dependent on seizure discharges per se, but rather may be related to certain types of hemispheric interaction.
