Anosognosia sufferers are paralyzed but won't admit it. They tell their doctors and loved ones they have severe arthritis or need to watch their weight if asked to move their incapacitated arm to take a piece of candy. They lie, but they don't know they are lying. The deception is only directed inward. They truly believe the fiction. • A person with Capgras delusion believes their close friends and family have been replaced by impostors. The part of the brain that provides an emotional response when you see someone you know stops functioning properly in those with this dysfunction. They recognize their loved ones, but don't feel the spark. They make up a story to explain their confusion and accept it entirely. • Those with Cotard's syndrome believe they have died. Those with this affliction will assume themselves to be spirits in an afterlife and believe the delusion so strongly they sometimes die of starvation.
