Parkinson's Disease: Making a Difference Today
Each year, about 50,000 Americans are diagnosed with Parkinson's disease, joining the estimated 1 million people already living in the United States with this serious and disabling brain disorder. Parkinson's occurs when nerve cells become damaged or destroyed in the substantia nigra, an area of the brain that is important for normal voluntary movement and coordination. People with Parkinson's experience trembling, muscle stiffness, and slowness of movement. They also often experience depression, anxiety, dementia, constipation, urinary difficulties, and sleep disturbances. Symptoms tend to worsen over time.
