People with Capgras Syndrome act as if they are in a parallel universe in which
the people they know are "doubles" or "impostors."
The material in this article is presented in greater detail in my book Sex, Drugs, Einstein, and Elves.
When people with Capgras Syndrome see a friend, spouse, or themselves in a mirror, they believe they are seeing an exact double or an impostor.
Sometimes, people with Capgras Syndrome even believe that inanimate objects -- like a chair, watch, book, or lamp -- have been replaced by exact replicas. If people own a pet, the pet may be seen as an impostor, a strange animal roaming through their lives and homes.
Capgras patients are often so disturbed when they see a doppelganger in the mirror that they remove all mirrors from the home. The syndrome, named for French psychiatrist Jean Marie Joseph Capgras, afflicts thousands of people in the United States.
Some people with Capgras Syndrome have epilepsy or strange-looking temporal lobes in the brain.
The Capgras' patient identifies his or her spouse as being an imposter - identical in every possible way, but an identical replica. The patient will accept living with these imposters but will secretly "know" that they are not the people they claim to be.This reminds me of the movie "Invasion of The Body Snatchers".
