Testosterone and Parkinson's Disease

Parkinson’s is a slowly progressing disease that causes changes in the brain leading to low dopamine levels. The decrease causes tremors and loss of balance, stiffness of limbs, and loss of facial expression. Parkinson’s disease affects about 1.2 million people in the United States. In a study conducted by Dr. Pahan, of Rush University, mice with Parkinson’s pathology were given testosterone pellets and the Parkinson’s symptoms reversed. This study was funded by the NIH, and further studies will be forthcoming to see if comparable results can be expected or identified among humans.
