The neglected side of Parkinson's disease

Parkinson's disease is not an epidemic one but it is more common that most people might think. About 1,000,000 Americans suffer from it with 60,000 new cases appear annually in the United States alone. Usually hits people at the age of 60, it has also the possibility to strike at an early stage of life as with actor Michael J. Fox at 30 and Muhammad Ali at 42. The common symptoms appear to be with shaking, slowness of movement and problems with balance. Neuroscientists found a way to treat such disease as they have found out that this disease was with a dopamine deficiency. However, there are other aspects of the disease that does not respond to this treatment where most physicians are unfamiliar with such nondopaminergic manifestations. These include sleep disorders, dementia, and difficulty of walking. Considering the understanding of past diseases might help with the solution of this Parkinson's disease.
