Abstract

We report a 40-year-old man with known neuro-Behcet's disease who showed Fregoli syndrome after a seizure attack. A patient with Fregoli syndrome strongly believes that the psychological identity of a familiar person remains unchanged while at the same time there is a marked change in physical identity. The anatomical basis of Fregoli syndrome is still unclear; our patient showed right hippocampal vasculitis in MRI and frontal dysfunction in neuropsychological testing.
