Does levodopa aggravate Parkinson's disease?
We studied the possible deleterious effect of levodopa therapy on 185 patients with Parkinson's disease and concluded that the time when levodopa is introduced, the daily dose, and the duration of treatment do not aggravate Parkinson's disease. We also studied 72 parkinsonian patients with levodopa-induced abnormal involuntary movements to see whether early initiation of levodopa therapy affected the time of onset of abnormal involuntary movements. The results suggested that it did not, and that levodopa was started early in these patients because of the severity of their motor disability.
