Headline: Lifestyle Choices and Vascular Health Linked to Accelerated Brain Aging, Study Finds
Subhead: Researchers at the Karolinska Institute find that factors harming vascular health are associated with a ‘older-looking’ brain, while a healthy lifestyle correlates with a ‘younger’ brain.
In a breakthrough study published in the journal Alzheimer’s & Dementia: The Journal of the Alzheimer’s Association, researchers from the Karolinska Institute in Sweden have discovered that certain lifestyle factors and health conditions can influence the aging process of the brain. The study, led by Dr. Anna Marseglia, aimed to understand what could boost the brain’s resistance against age-related deterioration, given the limited effectiveness of current Alzheimer’s medications.
The research team analyzed MRI images of the brains of 739 cognitively healthy 70-year-olds, along with data on their health, lifestyle, and cognitive function. They estimated the ‘brain age’ of each participant using an AI-based algorithm and found that several factors linked to poor vascular health were also associated with a brain that appeared older than its years.
"We found that diabetes, stroke, small vessel disease in the brain, and inflammation were all linked to brains that looked older," explained Dr. Marseglia. "Conversely, a healthy lifestyle, characterized by regular physical exercise, was associated with a brain that appeared younger."
The study highlights the importance of maintaining good vascular health to protect the brain. Factors that negatively impact blood vessels, such as inflammation and elevated blood sugar levels, can accelerate brain aging. By contrast, a healthy lifestyle can help keep the brain in better shape.
Dr. Marseglia concludes, "Our findings underscore the critical role of maintaining healthy blood vessels to support brain health. Simple lifestyle changes, such as engaging in regular physical activity, can contribute to a younger, more vital brain."
The results emphasize the crucial role of a healthy lifestyle and proper management of health conditions in preserving brain health and potentially delaying cognitive decline. As the global population ages, understanding the factors that can influence brain aging could be vital in developing effective strategies to support brain health and prevent age-related cognitive disorders.
