Can a longevity protein protect Parkinson's patients from memory loss?

A protein that naturally extends lifespan might protect Parkinson's patients' thinking and memory, pointing to new treatments.

A protein called klotho, known to extend lifespan and boost brain function, appears to protect people with Parkinson's disease from cognitive decline—at least in genetic studies and mouse models. Researchers found that higher klotho levels …
