If you want to save your brain, focus on keeping the rest of your body well with exercise and healthy habits rather than popping vitamin pills, new guidelines for preventing dementia advise.
About 50 million people currently have dementia, and Alzheimer’s disease is the most common type. Each year brings 10 million new cases, says the report released Tuesday by the World Health Organization.
Although age is the top risk factor, “dementia is not a natural or inevitable consequence of aging,” it says.
Many health conditions and behaviors affect the odds of developing it, and research suggests that a third of cases are preventable, said Maria Carrillo, chief science officer of the Alzheimer’s Association, which has published similar advice.
