What Are the Causes of Parkinson’s disease?
Parkinson’s disease is chronic and progressive. The question now here is what causes this disease.
The symptoms and not actually the disease itself are cause by a loss of nerve cells (dopaminergic cells) in the substantia nigra, a part of the brain. Dopamine as produced by the dopaminergic cells, is a neurotransmitter that helps transmit the message to the brain and that control body movements while coordinate them to the body parts. Now, the dopamine allows the substantia nigra and corpus striatum to communicate and this conversation does proper movements of the muscle.
If these cells in the brain now are damaged, the production of the dopamine goes down and the messages from the two parts of the brain do not work properly. These symptoms appear when a large portion of these nerve cells are lost. The worst thing here is, as the dopamine levels continue to drop, the signs and symptoms get worse.
