if you were stranded on a desert island with a sufferer of "an unusual neurological state," which state would it be?

Kluver-Bucy Syndrome: "Damage to the front of the temporal lobe and the amygdala just below it can result in the strange condition called Kluver-Bucy Syndrome. Classically, the person will try to put anything to hand into their mouths and typically attempt to have sexual intercourse with it. A classic example is of the unfortunate chap arrested whilst attempting to have sex with the pavement. Effectively, it is the 'what' pathway that is damaged with regards to foodstuff and sexual partner. As Ramachandran puts it, 'they are not hypersexual, just indiscriminate.'"

Cotard's Syndrome: "Named after a French psychiatrist Jules Cotard, this syndrome is characterized by the patient believing that he is dead, a walking corpse. This 'delusion' is usually expanded to the degree that the patient might claim that he can smell his own rotting flesh and feel worms crawling through his skin."

Capgras' Syndrome: "Brilliantly described by Ramachandran, Capgras' syndrome is another neurological syndrome that is often mistaken for insanity. The Capgras' patient will typically identify people close to them as being imposters - identical in every possible way, but identical replicas. Classically, the patient will accept living with these imposters but will secretly 'know' that they are not the people they claim to be."
