Scientists report that raising levels of the life-extending protein klotho can protect against learning and memory deficits in a mouse model of Alzheimer’s disease.

Remarkably, this boost in cognition occurred despite the accumulation of Alzheimer-related toxins in the brain, such as amyloid-beta and tau.

Alzheimer’s patients have brains with significantly more genetic variation than the brains of those without the disease, according to a study led by scientists at The Scripps Research Institute.

The finding may help scientists track down the mechanism that causes nearly all cases of Alzheimer’s, a mechanism that is not well understood.
