Cotards Sindrome, Nerological Disorder

Cotards sindrome is a nerological disorder in which people believe they are dead and their body is rotting. They often refuse to eat, and in some cases, request to be taken to the morgue. The core seems to be that the part of their brain is damaged that makes them feel as if they exist. So this is a denial of existence. They think they don't exist. But another aspect of it, an this is where, like, different patients may have slightly different manifestations of it, is that they have no emotions, and they interpret that as being dead.
