If you’re finding it harder to remember where you put the car keys, the culprit could be a brain protein with a name that’s easy to forget: RbAp48.

A shortage of this protein appears to impair our ability to remember things as we age, researchers report in the current issue of Science Translational Medicine. And boosting levels of RbAP48 in aging brains can reverse memory loss, at least in mice, they say.

The protein was studied in an area of the brain that is generally unaffected by Alzheimer’s disease.
The research “reinforces the emerging idea that Alzheimer’s disease and aging are separate entities,” says Scott Small, a neurologist at Columbia University and one of the study’s authors. It also suggests that, eventually, it should be possible to treat memory loss that’s not related to Alzheimer’s.
