The global prevalence of Parkinson's disease has doubled in the past 25 years. While research into this extremely diverse neurodegenerative disorder is very active, there is much left to be uncovered about the underlying cause of the disease. Recently, Northwestern Medicine investigators have discovered novel genetic factors contributing to the risk of Parkinson's disease, which may lead to potential therapeutic targets. Steven Lubbe, PhD, assistant professor of Neurology at Feinberg, discusses these findings recently published in the journal Brain.
