April is Parkinson’s Awareness Month.

The causes of Parkinson’s disease are currently unknown. The degenerative disorder of the nervous system is marked by tremors, muscle stiffness and impaired movement.

Recent studies suggest Parkinson’s disease may occur in higher rates among Latinos — but it’s tough to know why that might be, as Latinos are underrepresented in Parkinson’s research.

Joining “Latino Voices” with more are Dr. Mitra Afshari, assistant professor of neurology at Rush University Medical Center; Rosa Peña, vice president of programs and services at the American Parkinson Disease Association; and Dr. Paulina Gonzalez Latapi, an assistant professor of neurology at Northwestern University School of Medicine who leads Northwestern’s Hispanic Movement Disorders Clinic.
