Dementia: 10-year risk estimates may inform prevention

A large study provides 10-year absolute estimates for dementia risk. The scientists hope that by identifying people at high risk, specialists might be able to put in place early strategies for prevention.
According to the World Health Organization (WHO), every 3 seconds a new case of dementia is diagnosed. It is characterized by cognitive impairment, such as having trouble recalling memories, solving problems, and reasoning logically. Some of the main dementia risk factors include aging, stroke, and high blood pressure.
Recent studies have also found that biological sex and a particular variation in the APOE gene — the e4 allele — both affect a person's overall risk.
