According to a recent study published in the Journal of Neurology, Neurosurgery, and Psychiatry, addressing health factors within our control can significantly reduce the risk of dementia, stroke, and late-life depression. The study found that at least 17 lifestyle factors contribute to these conditions, including blood pressure, body mass index, kidney disease, and sleep.
The researchers reviewed 59 meta-analyses of data from multiple studies and identified a common set of risk factors shared by all three conditions. Blood pressure had the biggest impact, with high levels increasing the risk of stroke by over two-fold and dementia by 20%.
Other key influencers include smoking, stress, physical activity, and blood sugar levels. Experts recommend addressing these factors through lifestyle changes such as:
* Lowering high blood pressure by exercising regularly, losing weight, managing stress, and getting enough sleep
* Quitting smoking with the help of helplines, apps, and doctors
* Improving fitness through regular exercise
* Regulating blood sugar levels through a healthy diet and exercise
The study also highlights the importance of social engagement, cognitive activity, and purpose in life. By addressing these factors, individuals can reduce their risk of age-related brain diseases.
Dr. Sanjula Singh, senior study author, noted that “this study shows how powerful lifestyle and behavioral changes are for age-related brain diseases.” The researchers hope to empower people with a hopeful message, encouraging them to work on multiple goals using the same tools.
A new version of the Brain Care Score will be developed, incorporating additional factors such as pain, depressive symptoms, and hearing loss. This score aims to help individuals gauge and manage their risk for dementia or stroke without medical procedures.
