New Drug May Prevent Cognitive Decline in Parkinson's Disease

A decline in motor skills is a hallmark of Parkinson's disease, regularly taking the form of slowness, rigidity, and tremors. Yet the condition commonly affects other neurological functions as well, impacting mood and causing a decline in cognition. A drug that blocks a key receptor linked with blood pressure has shown promise in recovering memory in models of vascular dementia, inspiring researchers from the University of Arizona to test the treatment on mice with Parkinson's-like symptoms.
