Hi c:

Walking corpse syndrome (cotard’s syndrome) is a rare mental disorder in which a person believes that they are dead.

For example, a British man, Graham woke up nine years ago convinced he was no longer alive although he was still breathing. Doctors diagnosed him with cotard’s syndrome, but Graham did not believe them. He insisted that he was dead. 

The unusual condition emerged after Graham, who suffered from severe depression, tried to commit suicide by taking an electrical appliance with him into the bath.

Eight months later he told doctors that his brain had died or was, at best, missing.

He even stopped eating, smoking and drinking because there was no point and he was “dead”. He felt compelled to go to his local cemetery because he thought he would fit in. 

Graham’s brain scans resembled those of a person in vegetative state or under anesthesia. Luckily after months of therapy, he was able to overcome his condition. 

Cotard’s Syndrome is among the most rare diseases in the world and it is thought that it affects just few hundred people at any one time.

It is linked to depression and comes in a variety of forms including some who feel that their limbs are no longer functioning.
