Earlier, much smaller U.S. studies conducted in the mid-1980's had suggested roughly 60,000 people are diagnosed with Parkinson's disease each year.
The estimated economic cost is $52 billion annually in the United States alone, according to a report of the study published in npj Parkinson's Disease.
Fox Foundation for Parkinson's Research obtain increased funding for research and access to care.
A separate study by Beck's team recently put the number of U.S. patients living with Parkinson's disease at nearly 1 million, whereas earlier estimates had been closer to 650,000, he said.
"Because the U.S. population is aging, a lot of people are going to be entering the health system with Parkinson's disease," Beck said, "and there are only about 700 neurologists in the country who specialize in movement disorders."
