Dementia prevention focuses on reducing risk factors that contribute to cognitive decline. Maintaining a healthy lifestyle plays a key role, including regular physical activity, a balanced diet (like the Mediterranean or DASH diet), and staying mentally active through learning and social engagement. Managing health conditions such as hypertension, diabetes, and high cholesterol is crucial, as they increase the risk of dementia. Avoiding smoking and excessive alcohol consumption also helps. While there’s no guaranteed way to prevent dementia, research suggests that staying physically, mentally, and socially engaged may delay or reduce the likelihood of developing cognitive impairments.
