Brain age gap may influence the relationship between cognitive impairment risk factors

The difference between the brain's predicted age and actual chronological age, called a brain age gap, may influence the relationship between cognitive impairment risk factors, like high blood pressure and diabetes, and a person's cognitive performance, also known as thinking and memory skills, according to a study published June 18, 2025, in Neurology, the medical journal of the American Academy of Neurology.
