Parkinson’s is a progressive disease caused by a decreased level of dopamine produced by nerve cells in the brain, in an area called the substantia nigra. Dopamine levels drop as the disease progresses. Dopamine sends messages in the brain to areas that control movement and coordination. With decreased dopamine, patients have difficulty controlling their limb and overall body movement along with their emotions.
Approximately 1,000,000 adults in the USA have Parkinson’s Disease, while males have a 50% higher risk than females.
