People whose scores on a dementia risk test indicated a less brain-healthy lifestyle, including smoking, high blood pressure and a poor diet, may also have the following: lower scores on thinking skills tests, more changes on brain scans and a higher risk of cognitive impairment. That’s according to a new study published in the August 25, 2021, online issue of Neurology. The study also found that in men, the test scores were associated with poor memory function and markers of brain shrinkage.
