Parkinson's Disease is a disorder that affects nerve cells, or neurons,
in a part of the brain that
controls muscle movement. In Parkinson's, neurons that make a chemical
called dopamine, die or do not work properly. Dopamine normally
that help coordinate your movements.
No one knows what damages these cells.
Symptoms of Parkinson's Disease may include trembling of hands,
arms, legs, jaw and face.
• Stiffness of the arms, legs and trunk.
• Slowness of movement.
• Poor balance and coordination.
As symptoms get worse, people with the disease may
have trouble walking, talking or doing simple tasks.
They may also have problems such as depression, sleep problems or
trouble chewing, swallowing or speaking.
Parkinson's usually begins around age 60, but it can
start earlier. It is more common in men than in women.
