Unearthing Parkinson's causes

The link between dopamine and Parkinson's disease
Dopamine is a neurotransmitter that facilitates the brain's communications within itself and with other body organs. In some people, dopamine production slows down considerably because the cells which produce it begin dying. The real reasons for the death of cells in the group called substantia nigra (which is responsible for dopamine production) is not known. That's another way of saying that we do not have a full picture of how and why Parkinson's disease develops in the first place.

Recent information about Parkinson's disease
It is generally known that Parkinson's disease tends to affect older people more than younger ones. However, age is not the only factor involved; genetics may play a role too, along with other factors. This is true even though approximately 90% of Parkinson's cases diagnosed are in those above age 60. And the risk tends to increase with age, except for one surprising statistic.
