Parkinson’s Disease Symptoms Seen Years Before Diagnosis

Data from a new U.K. study with the most diverse group of patients ever reported show that Parkinson’s disease symptoms — including tremors, cognitive difficulties, epilepsy, and hearing loss — can emerge up to 10 years before a diagnosis. Moreover, ethnicity or socioeconomic status were not found to be associated with Parkinson’s risk.

This study confirms that many of the symptoms and early features of Parkinson’s can occur long before a diagnosis,” Alastair Noyce, PhD, the study’s lead investigator and a researcher at Queen Mary University of London, said in a university press release.

We’re hoping to identify people at high risk of Parkinson’s even before obvious symptoms appear — which means that we could do more than just improve quality of life for patients, and perhaps be in the position to slow down or cure Parkinson’s in the future,” Noyce said.

Importantly, this study also identified hearing loss and seizures as early symptoms of Parkinson’s disease.

The study, “Assessment of Risk Factors and Early Presentations of Parkinson Disease in Primary Care in a Diverse UK Population,” was published in JAMA Neurology.
