i hope you are right about virus. my idea is pd is a damage! in my brothers case, his job put him inhaling co in dangerous levels over a period of time.i even found info at a hospital library saying head trama,or carbon monoxide could bring on the onslaut of pd. scans show leisions in the brain. damage!..in my brothers case he visited me once a year and when he got here the hell began....terrible total freezes, confusion,on,offs[much more offs] . i would find him lying on the floor naked unable to move , even enough to get a med or move off of something that was hurting him terribly...each visit i worked to get his meds to a minimum and diet corrected...he left doing and felling much better....how about marijuana? we,ve experimented and there is benifits.....can you post this letter to all? Have A Great Day, Bill. ---------------------------------------------------------------------- To sign-off Parkinsn send a message to: mailto:[log in to unmask] In the body of the message put: signoff parkinsn
