Abstract
IN Parkinson's disease severe decreases occur in striatal L-dopa decarboxylase, putaminal synaptosomal uptake of dopamine, and dopamine and homovanillic acid concentrations in the nigro-striato-pallidal complex1–4. In addition, L-glutamic decarboxylase (GAD) activity is decreased in the caudate nucleus5. The experiments described here were performed to further evaluate this finding and to determine the effect (if any) of L-dopa therapy.
