Periictal Capgras syndrome after clustered ictal fear: depth-electroencephalogram study.
OBJECTIVE
To describe periictal Capgras syndrome as a result of rapid, successive bouts of ictal fear.


METHODS
This periictal psychotic state was documented by depth EEG recordings.


RESULTS
Episodes of paroxysmal fear, experienced as a vivid sensation of someone being nearby, corresponded with unilateral left limbic ictal discharge.


CONCLUSIONS
Depersonalization, regardless of organic or functional origin, is an important contributor to the genesis of Capgras syndrome.
