Has incidence of Parkinson's disease increased over past 30 years?

Predicting cognitive deficits in people with Parkinson's disease. Parkinson's disease is commonly thought of as a movement disorder, but after years of living with the disease, approximately 25 percent of patients also experience deficits in cognition that impair function. A newly developed research tool may help predict a patient's risk for developing dementia and could enable clinical trials aimed at finding treatments to prevent the cognitive effects of the disease.
