Daily brain training may prevent Alzheimer’s

Although previous research findings have suggested that engaging in mentally demanding activities – such as reading, writing and playing games – may help stave off the disease, the latest study identifies the relevant biological target.

The study, led by researchers at the University of California, shows the discovery could guide future research into effective prevention strategies.

"Rather than simply providing resistance to Alzheimer's, brain-stimulating activities may affect a primary pathological process in the disease," said principal investigator Dr William Jagust of UC Berkeley's Helen Wills Neuroscience Institute.

"This suggests that cognitive therapies could have significant disease-modifying treatment benefits if applied early enough, before symptoms appear," he said in a statement.

In the first study of its kind, researchers used brain scans to examine the amount of beta amyloid deposits in the brains of
