LACK OF FOLIC ACID AND PARKINSON'S DISEASE

Gabe Mirkin, M.D.

A study in the Journal of Neurochemistry shows that lack of folic 
acid may cause Parkinson Disease.

 
Mice that were fed MPTP, a chemical that causes Parkinson's disease, 
and were also given folic acid did not develop full blown 
Parkinson's disease. Those given MPTP and fed a diet low in folic 
acid developed severe shaking and lack of muscle control 
characteristic of Parkinson's disease. 

Lack of this vitamin causes homocysteine to accumulate in the 
bloodstream which damages DNA in the substantia nigra, a part of the 
brain rich with dopamine cells. This lowers brain levels of dopamine 
which causes Parkinson's disease. Green leafy vegetables, citrus 
fruits and juices, whole grains and dry beans are good sources of 
the vitamin. Lack of folic acid can also cause heart attacks and a 
type of birth defect in which the spine does not close normally.
