Every year, April 11 is observed as World Parkinson's Day. The day aims to amplify awareness and understanding about Parkinson's disease internationally.

World Parkinson's Day marks the birthday of Dr James Parkinson, the British physician who first described the symptoms of the disease in his groundbreaking essay, 'An Essay on the Shaking Palsy,' published in 1817.

Parkinson disease (PD) is a brain condition that causes problems with movement, mental health, sleep, pain and other health issues. PD gets worse over time. There is no cure, but therapies and medicines can reduce symptoms. Common symptoms include tremors, painful muscle contractions and difficulty speaking.
