Can We Stop Parkinson's from Spreading? With a drug that already exists!

What if Parkinson's disease doesn't just damage the brain — but actually spreads from one cell to another? Researchers at Johns Hopkins may have found a key gateway that makes that possible. And here's the part that surprised me: the drugs that might block it already exist. In this video I break down what LAG-3 and APLP1 are, how they work together to let toxic alpha-synuclein enter neurons, what happened when researchers blocked that process in mice — and why a class of cancer drugs is now being looked at in a completely new way. This is early research. But it's real progress — and I think every family living with Parkinson's should know about it. Can we stop Parkinson's from spreading? I hope so! I'm Kim. I walked this journey with my mom for over a decade. Now I make these videos to help caregivers and patients understand what's happening in Parkinson's research — without needing a medical degree to follow along. 🔔 Subscribe so you don't miss new videos every week.
