The British Journal of Nutrition has reported on a study that was done in Japan. This study has suggested that Vitamin B6 may well turn out to be very important in the future treatment of Parkinson's disease. A deficiency of Vitamin B6 may dramatically increase the chances of developing Parkinson's disease by as much as fifty percent.
"Parkinson’s disease, named after Dr. James Parkinson, the London doctor who initially identified it as a particular condition, occurs when nerve cells are lost in a part of the brain called the substantia nigra."
It is known that there is some relationship between B vitamins and an amino acid called homocysteine. Homocysteine has a profoundly negative effect on brain cells.
Other vitamins were also studied. They were Vitamin B12, folate, and riboflavin. This additional research did not find a correlation to exist between any of these vitamins and the development of Parkinson's disease.
