Study finds probiotic no better than placebo for Parkinson’s anxiety
Researchers tested whether a probiotic supplement could help reduce anxiety in people with Parkinson's disease. The supplement did not work better than a placebo (a fake pill) for anxiety. However, people who took the supplement did show some improvement in thinking and memory tests, though researchers said this result needs more study before drawing conclusions.
WHY IT MATTERSIf probiotics could help with cognitive symptoms in Parkinson's disease, it might offer a simple, accessible option alongside standard treatments—but this trial suggests anxiety relief isn't one of those benefits.
