Bob and list, Bob Fink kindly reminds me of an inadvertent omission in my post on Parkinsonism. There is a condition called tardive dyskinesia which can occur in patients on long-term neuroleptic treatment usually for schizophrenia. This condition resembles dyskinesia many of us get with Sinemet. It can be at times irreversible even after the precipitating meds have been withdrawn. It is a risk with neuroleptics but is not related specifically to PD symptoms. It is thought to be the result of receptor supersensitivity. Thanks Bob for that addition. Charlie "Robert A.
