Hi Nancy Spires, Alien limb as a symptom of CBGD can not be mistaken for what you are describing. Usually an arm moves as if it has a mind of it's own. The person has absolutely no control over it. Is not like "freezing". It is not a psychosis. It is not an autoimmune problem. My husband had CBGD. His mind was clear and good to the very end. If you want me to describe what it is to have CBGD, let me know. Best wishes, Audrey in Pa. ----- Original Message ----- From: Nancy Spires <[log in to unmask]> To: <[log in to unmask]> Sent: Wednesday, June 21, 2000 9:52 PM Subject: Re: Reply to alien limb > is this necessarily a psychosis in someone w/pd? i thought it was an > autoimmune problem. i feel sometimes that my limbs don't move > automatically--i need to tell them how to move step-by-step ("manually"). n > spires
