Case #1 A 30-year old woman who had been in a car accident 8 years prior had been misidentifying strangers as people she knew. She misidentified a patient as her boyfriend, a nurse as her mother and the social worker as her sister. She was convinced her family was turned into strangers. Her EEG showed a spike and sharp waves in the left temporal lobe and her MRI was normal. She was treated with risperidone and her oxcarbazepine was increased to 900 mg twice a day. Her symptoms were completely resolved in a month. She had no memory of misidentifying people. Case #2 A 58-year old woman previously diaganosed with paranoid schizophrenia called the police stated there was a stranger in her home. When they arrived she said her husband was an imposter pretending to be her husband. They took her to a psychiatric hospital where she accused her doctor as being an imposter. She stated that a woman down the street from where she lived was stealing her things and replacing them with "old stuff." She was treated with Risperidone 2mg/day which improved her paranoid symptoms but not her Fregoli Delusion. When she was released she still believed her husband to be an imposter.
