However, Parkinson's disease is so intricate that scientists are still trying to understand it.
Parkinson’s disease is a neurodegenerative disease that involves the brain and nerve cells. Cells in a certain part of the brain stop working properly and are lost over time. These nerve cells manufacture a vital chemical called dopamine, which the brain uses dopamine to send messages to control movement. Everything, from everyday things walking, talking, writing and even smiling. Eventually the time comes when the brain cannot keep the body moving properly. This is when the symptoms start to set in. At first, there are minute details and tells of the symptoms, like handwriting becoming smaller, but then symptoms continue and more recognizable symptoms, like slowness, stiffness, and tremors. Scientists do not understand why cells that produce dopamine seem to be under attack by Parkinson’s. As of right now, there is no cure, but it is being worked on.
