What Is Parkinson’s Disease? Symptoms, Causes, Medications &Treatment

Parkinson’s disease or disorder is a degenerative disorder of the central nervous system. In the United States, an estimated 60,000 new cases of Parkinson’s disease (PD) are diagnosed each year. The incidence of PD is higher in men than in women and increases with age. It is estimated that one million people in the United States live with PD.

The average age of onset in this case is 60 years, although 5–10% of cases are diagnosed before the age of 50, and some very rare cases have been diagnosed in children. The prevalence of PD doubles every 5 to 10 years above the age 55.

There are several possible causes of PD, but the underlying cause is unknown in most cases. A small percentage of cases (<5%) are caused by genetic mutations, and environmental factors may play a role in other cases. It can significantly reduce quality of life and lead to disability. There is no cure, but there are treatments that can help relieve symptoms and improve quality of life.
