Parkinson’s disease is a brain disorder that causes shaking and other uncontrollable movements, balance and coordination problems, and stiffness. Symptoms usually start out mild and get worse over time. As the disease advances, it can interfere with walking and talking. Parkinson’s also can cause mental and behavioral changes, sleep problems, depression, memory issues, and exhaustion.
What causes it
Parkinson’s is caused by reduced production of dopamine, an important chemical in the brain. This reduction occurs when nerve cells in the brain that produce dopamine become impaired or die. Researchers do not know what causes these cells to die. There is no cure for Parkinson’s, but medication, surgery, and other treatments often can relieve some symptoms.
Parkinson’s usually affects people age 60 or older, though 5-10% of cases start before age 50. Some research suggests that it affects more men than women. Certain forms of Parkinson’s that begin at a younger age may be passed down from parents. Other forms of the disease have been linked to abnormalities in a person’s genes. Nearly 90,000 people are diagnosed with Parkinson’s disease every year in the United States, and that number appears to be growing quickly.
