Parkinson's Disease
|
Parkinson’s is a neurodegenerative disease. Movement is normally controlled by dopamine, a chemical that carries signals between the nerves in the brain. When cells that normally produce dopamine die, the symptoms of Parkinson’s appear.
The most common symptoms are:
-
Tremor
-
Slowness and stiffness
-
Impaired balance
-
Rigidity of the muscles |
