Smoking and High Blood Pressure: Silent Threats to Brain HealthThe study revealed that several common health conditions were linked with faster progression of brain damage. Maintaining healthy blood pressure, controlling cholesterol levels and preventing heart disease may therefore represent important steps in protecting cognitive health. Long-term conditions such as hypertension, diabetes and high cholesterol can damage blood vessels, increase inflammation and interfere with the brain’s ability to receive adequate oxygen. While ageing and genetics remain important factors, scientists increasingly believe that lifestyle-related risks can influence how quickly harmful brain changes progress. The research serves as a reminder that the future of brain health is not determined only by biology but also by behaviour.
