Is Parkinson’s fatal?

Parkinson's disease is not fatal per se, but it can reduce life expectancy. The disease tends to progress more quickly in older patients, and may lead to severe incapacity within 10 - 20 years. Older patients also tend to have more cognitive symptoms and decline in function than younger people living with PD. Treatment advances are increasingly effective in alleviating symptoms and have had an impact in increasing life expectancy.
