Breakthrough Protein Discovery Offers Hope for Parkinson's Cognitive Decline
Researchers at the University of Arizona have found that a drug called PNA5 may help prevent cognitive decline in Parkinson's disease by reducing inflammation in the brain. In studies on mice, PNA5 improved memory and slowed brain cell loss by calming overactive immune cells known as microglia. While promising, further research is needed to confirm the drug's safety and efficacy in humans. This development offers hope for addressing the cognitive symptoms of Parkinson's, which currently lack effective treatments.
