Brain volume and cardiovascular risk are predictors of the rate of age-related cognitive decline
Biomarkers of aging and cognitive decline - short neuroscience news

Two studies of a 20-year long research project have given more insight into how our brain ages, and which factors influence this. Participants were from the population-based Women’s Healthy Ageing Project, and were thus all women. In the first study, brain MRI scans taken at the age of 60 could predict memory decline at the age of 70. This result is in line with earlier observed links between brain shrinkage and cognitive decline. The second study found that high cardiovascular risk in midlife to late life indicates a higher likelihood of vascular brain damaged aged over 60. High cardiovascular risk involved high cholesterol, low “good” cholesterol (HDL), high blood pressure, smoking and diabetes. Researchers say that women should watch their cholesterol and blood pressure to avoid cognitive decline during aging as much as possible.
