Exercise may help ward off Alzheimer’s
Scientists believe the protein PGC-1alpha could open the door to new ways of treating Alzheimer’s.
The protein has metabolic effects that also appear to guard against type 2 diabetes.

Since exercise is known to raise levels of PGC-1alpha, the findings may help explain the link between regular physical activity and reduced Alzheimer’s risk.
They also provide a clue to why people with diabetes are more likely to develop Alzheimer’s.
Magdalena Sastre, from Imperial College London, who led the study, said: “These early results tell us much more about how diabetes and Alzheimer’s are linked, but more importantly, they have given us a potential treatment target. Research is the only way to defeat dementia.”
