Isolated Jaw Tremor in Patients With Parkinson's Disease

Some of the people with isolated jaw tremor did eventually develop clinical Parkinsonian symptoms, a fewer of those actually pathologically had Parkinson's disease. It certainly was not a majority and it was a very small subset within that group. The big disease process that might be missing that never made it to this program are those with dystonia. So if they very clearly and obviously have dystonic features in their lower jaw movements, whether that as an asymmetry or sort of a bruxism type related dystonia, they may never have been included in this analysis.
