I've been encouraged by friends to try acupuncture, but have no experience with it.
I found this article (from December 2012?) on the Northwest Parkinson's Foundation website:

"New research reveals how acupuncture protects the brain in areas damaged by Parkinson’s disease. Scientists at the World Health Organization Collaborating Center for Traditional Medicine have discovered two acupuncture points that prevent the breakdown of an important brain protecting enzyme, tyrosine hydroxylase. This enzyme helps the body to create L-DOPA, an important dopamine precursor and drug used in the treatment of Parkinson’s disease. It is now known that acupuncture prevents decreases of the L-DOPA creating enzyme in the thalamic portions of the brain thereby improving the motor function that is destroyed by Parkinson’s disease.
Loss of dopamine neurons in the substantia nigra portion of the brain is a key pathology in Parkinson’s disease and tardive dyskinesia. The World Health Organization (WHO) scientists have discovered that acupuncture inhibits decreases of tyrosine hydroxylase in nigrostriatal dopaminergic neurons thereby protecting dopamine neuron levels in the substantia nigra portion of the brain. Depletion of these neurons leads to Parkinson’s disease and acupuncture stimulation of acupoints GB34 and LV3 prevents depletion by sustaining tyrosine hydroxylase levels."
I'm not sure about the reliability of the research. Worth a try? And does it have to be regular (weekly?) sessions to make a difference if it in fact works?
