NY Times on Capgras Syndrome

Caprgras Syndrome is a mental condition that causes those afflicted to think that they people they know have been replaced by imposters, a la Invasion of the Bodysnatchers.

My patient, a 37-year-old homemaker, gazed at the man in the red plaid shirt as he sat on the couch in her living room.

"Who are you?" she asked.

There was something familiar about him. He wore her husband's boots, but the shirt made him look like a truck driver.

"Yeah, and who are you?" the man replied with a laugh. "Come here and give me a kiss."

She gave the man a peck on the cheek, but she felt guilty, fearing that her husband would arrive at any moment and admonish her. Not only did the man want a kiss – he also wanted sex!
