Parkinson's disease, which mostly affects older people but can even occur in younger adults, results from the gradual degeneration of nerve cells in the portion of the midbrain that controls body movements. The first signs are likely to be barely noticeable -- a feeling of weakness or stiffness in one limb, or a fine trembling of one hand when it is at rest. Eventually, the shaking (tremor) worsens and spreads, muscles become stiffer, movements slow down, and balance and coordination deteriorate...
There are many other procedures being researched. One of the most promising involves the transplantation of fetal dopamine neurons (tissue transplant) into the brains of people with Parkinson's disease. The hope is that these cells will be able to re-grow the damaged dopamine-producing nerve cells.
Alternative Treatments for Parkinson's Disease
Alternative therapy may also be used to treat Parkinson's disease. The most touted in recent years has been the effect of Vitamin E on reversing the progression of the disease; although, this effect is still being debated by the scientific community.
Relaxation and guided imagery have also been suggested to help with stress, depression, and anxiety. Medical studies have shown that relaxation and guided imagery may help slow the progression of symptoms as well as quicken healing time after surgeries or injuries.
