The possibility that vegan diets could be therapeutically beneficial in PD, by slowing the loss of surviving dopaminergic neurons, thus retarding progression of the syndrome, may merit examination.

2011 case study in the "International Journal of General Medicine" sought to reduce the negative side effects of the Parkinson's medication L-dopa, allowing patients to use larger, more effective doses. Researchers found that by administering a supplement containing 5-HTP, L-tyrosine and a sulfur amino acid with the L-dopa, side effects like involuntary movement, nausea and psychiatric symptoms do not occur, or are at least manageable because the supplement replaced chemicals that the L-dopa depleted or inhibited. A 2010 case study in the journal "Clinical and Experimental Gastroenterology" found that supplementing with 5-HTP and L-tyrosine helped a Crohn's disease patient experience remission once the proper serotonin levels were achieved. Of course, these examples are only case studies, not treatment plans, so more research is needed before the 5-HTP/L-tyrosine combo becomes a commonplace treatment for any condition........read more http://www.livestrong.com/article/539256-l-tyrosine-5-htp/
