Detailed explanation-1: -Scientists still do not know what causes the neurons to die. People with Parkinson’s disease also lose the nerve endings that produce norepinephrine, the main chemical messenger of the sympathetic nervous system, which controls many functions of the body, such as heart rate and blood pressure.
Detailed explanation-2: -Parkinson’s disease is caused by a loss of nerve cells in the part of the brain called the substantia nigra. Nerve cells in this part of the brain are responsible for producing a chemical called dopamine.
Detailed explanation-3: -In Parkinson disease, nerve cells in part of the basal ganglia (called the substantia nigra) degenerate. The basal ganglia are collections of nerve cells located deep within the brain.
