Nigral endothelial dysfunction, homocysteine, and Parkinson's disease.
We found increased levels of atherosclerosis-inducing homocysteine in parkinsonian patients with long-term application of levodopa compared with previously untreated parkinsonian patients and controls. We conclude that antiparkinsonian treatment with levodopa promotes occurrence of vascular disease in Parkinson's disease.
