Eric and Alan, I strongly support what you say Alan. Behavioral change with Parkinsons drugs unfortunately is not uncommon. Especially at high doses hallucinations and delusional behavior can occur. This is not necessarily related to dementia- which is the general loss of mental faculties similar to senility. In recent years there has been some good success with the use of Clozaril in controlling these effects. I suggest for anyone experiencing hallucinations, major behavioral change or delusions that they taqlk to their neurologist about a referral to a psychiatrist with experience in treating Parkinsons patients. Do not just tollerate physically abusive behavior. The caregiver will burn out and that will almost certainly be a negative for the patient. Like they tell you on an airplane during a depressurization emergency- put on your own mask first, then assist those who can't do it themselves. If the caregiver does not take care of their own needs first- then they endanger not only themselves but those they wish to help. Good luck, Charlie **************************************************************************** ************************************* Charles T.
