Parkinson's disease affects one percent of all those over the age of sixty-five and the condition can affect people much younger. Symptoms of Parkinson's include
tremors and difficulty moving. The disease occurs when production of the neurotransmitter dopamine is reduced. Dopamine is a substance that helps relay messages from the brain to the muscles, thus facilitating movements.
Exposure to certain
toxic chemicals and pesticides may play a role in causing Parkinson's disease.
