Parkinson's disease affects the way you move. It happens when there is a problem
with certain nerve cells in the brain. Normally, these nerve cells make an
important chemical called dopamine. Dopamine sends signals to the part of your
brain that controls movement. It lets your muscles move smoothly and do what you
want them to do. When you have Parkinson's, these nerve ceils break down. Then
you no longer have enough dopamine, and you have trouble moving the way you want
to. 2. No one knows for sure what makes these nerve cells break
down. But scientists are doing a lot of research to look for the answer. They
are studying many possible causes, including aging and poisons in the
environment. Abnormal genes seem to lead to Parkinson's disease in some people.
But so far, there is not enough proof to show that it is always
inherited. 3. Tremor may be the first symptom you notice. It is
one of the most common signs of the disease, although not everyone has it. More
importantly, not everyone with a tremor has Parkinson's disease. Tremor often
starts in just one arm or leg or only on one side of the body. It may be worse
when you are awake but not moving the affected arm or leg. It may get better
when you move the limb or you are asleep. In time, Parkinson's affects muscles
all through your body, so it can lead to problems like trouble swallowing or
constipation. In the later stages of the disease, a person with Parkinson's may
have a fixed or blank expression, trouble speaking, and other problems. Some
people also have a decrease in mental skills (dementia). 4. At
this time, there is no cure for Parkinson's disease. But there are several types
of medicines that can control the symptoms and make the disease easier to live
with. You may not even need treatment if your symptoms are mild. Your doctor may
wait to prescribe medicines until your symptoms start to get in the way of your
daily life. Your doctor will adjust your medicines as your symptoms get worse.
You may need to take several medicines to get the best results.
