Switching off just one protein could reverse brain ageing and prevent Alzheimer’s, study finds

A protein linked to the brain’s decline may be key to reversing memory loss and preventing diseases like Alzheimer’s, a new study says.

A growing body of research shows ageing is particularly harsh on the brain’s hippocampus, which is responsible for learning and memory. And ageing is the dominant risk factor for neurodegenerative disorders like Parkinson’s and Alzheimer’s.
