12 of The Rarest and Weirdest Diseases Know to Mankind
Alien Hand Syndrome
A very rare and particularly bizarre disease, Alien Hand Syndrome is a neurological disorder that causes the hand to operate independently of the brain and nervous system, or, the hand is thinking for itself.
Your hand will start grabbing for things and doing movements without you even realizing it.
At the moment, there is no cure, but holding an object in that hand is seen as the best therapy.
This strange disease makes the afflicted believe that they've died.
They basically turn into undead people as they continue to walk and talk to others believing that they've passed away.
Some folks take this delusion a step further and believe themselves to be immortal. Treatment for this odd condition requires drugs and hemodialysis.
