Parkinson's disease is characterized by gradual degeneration of neurons in a section of the brain. In normal conditions, these neurons release a chemical substance known as dopamine which is important for the brain.
Dopamine is a neurotransmitter which facilitates communication amongst different parts of the brain that is responsible for smooth muscle activity and proper nerve operation.
