What are the symptoms of Alien Hand Syndrome?
Symptoms of alien hand syndrome may include a feeling that the hand does not belong to its owner (alien hand sign); involuntary movements, such as one hand performing actions contrary to the other hand; a hand that performs activities not directed by the owner (anarchic hand) or levitating hand; and a feeling of having an extra limb (supernumerary hand). Individuals with alien hand syndrome may be groped by their own hand against their will, or they may slap the alien hand with their normal hand. The alien hand may grab things and not let go or even attempt to suffocate the patient.
