Recent brain imaging studies on 70-year-olds reveal a strong connection between blood vessel health and brain aging. Factors such as inflammation and high glucose levels are associated with an older-looking brain, while healthy lifestyles are linked to a younger, healthier brain.

Researchers from Karolinska Institutet, Sweden, highlighted that as global populations age, the prevalence of dementia is expected to rise. However, the study suggests that managing risk factors can influence the rate at which the brain ages, offering hope for improved cognitive health.
