It’s seen as encouraging news for people living with Parkinson’s Disease.

U.S. regulators have approved the first new drug in a decade to treat the chronic neurological disorder that causes tremors and movement difficulties.

It’s called Xadago, for use when a patient’s regular medicines aren’t working well.

The pill was tested in two six-month studies that included about 12-hundred patients taking the standard treatment, levodopa.

According to the Food and Drug Administration, adding Xadago decreased periods with troubling symptoms such as involuntary muscle movement.

Roughly 10-million people worldwide have Parkinson’s.

One of the most prominent is Canadian actor Michael J. Fox.
