According to the National Library of Medicine
Parkinson’s disease (PD) is a type of movement disorder. It happens when nerve cells in the brain don’t produce enough of a brain chemical called dopamine. Sometimes it is genetic, but most cases do not seem to run in families. Exposure to chemicals in the environment might play a role.
Symptoms begin gradually, often on one side of the body. Later they affect both sides. They include
- Trembling of hands, arms, legs, jaw and face
- Stiffness of the arms, legs and trunk
- Slowness of movement
- Poor balance and coordination
- As many as one million Americans live with Parkinson’s disease, which is more than the combined number of people diagnosed with multiple sclerosis, muscular dystrophy and Lou Gehrig’s disease.
- Approximately 60,000 Americans are diagnosed with Parkinson’s disease each year, and this number does not reflect the thousands of cases that go undetected.
- An estimated seven to 10 million people worldwide are living with Parkinson’s disease.
- Incidence of Parkinson’s increases with age, but an estimated four percent of people with PD are diagnosed before the age of 50.
- Men are one and a half times more likely to have Parkinson’s than women.
