New Research in Parkinson's Disease

The Journal of Parkinson's Disease (January issue), published findings of a study done concerning  mood and memory in those suffering from this disease.  Those people with higher blood levels of Vitamin D showed an improved mental and mood performance over those whose blood levels are low.

Neuropsychiatric performance in 286 Parkinson's patients was examined using cognitive function, memory and depression testing.  Those with higher vitamin D levels performed better on the neuropsychiatic, verbal memory and fluency scores.  Additionally, higher vitamin D levels correlated with significantly lower depression scores.

There continues to be disagreements among practitioners as to what amounts of vitamin D supplementation are optimal.  My recommendation is for all of us to try to get 15-20 minutes a day of sunlight exposure on as much of the body as possible.  In the winter months or if that amount of exposure is not possible, I recommend 2,000 to 5,000 IU of D per day...preferably a whole food source and not laboratory-manufactured.  For those with Parkinson's, they may need more, according to their individual performance and requirements.
