dear yen maybe this could be from being dehydrated. my husband fell and cut his head.he was in hospital 3 days and had series of tests and by elimination docter felt it was because he wasn't drinking cenough water. we started measuring his water and since he now drinks over half a gallon he has not had any more trouble.also i do not have parkinsons but last year when i was light headed i had to spend a day in hospital and they gave me i v solutions to put water in me. maybe it would be worth a try to increase drinking a lot more water. i sometimes have to tell jack to drink more as he forgets. this can't hurt and doesn't cost to try. love connie ----- Original Message ----- From: yen dinh <[log in to unmask]> To: <[log in to unmask]> Sent: Friday, April 28, 2000 9:00 PM Subject: Do you know anything about this symptom of Parkinson's diease?
