Better Than Drugs
"Sustained exercise may be able to slow or even reverse the biological changes that cause dementia, according to new research presented at the 2015 Alzheimer's Association International Conference in Washington. Researchers assigned 65 sedentary men and women with memory loss to either regular aerobic exercise or stretching for 45 minutes four times a week over six months. The aerobic exercise not only improved thinking but also reduced levels of toxic tau protein in the brain. No currently approved medication can rival these effects, said lead author Laura Baker of Wake Forest School of Medicine in Winston-Salem, N.C."
