Hypertension and heart disease contribute to dementia risk

High blood pressure and heart disease are linked to nearly half of all dementia cases, according to new research. The study suggests that modifiable risk factors, such as hypertension and hyperlipidemia, contribute significantly to dementia development, with changes beginning years before symptoms appear. Addressing these factors early in life may help prevent dementia, highlighting the importance of lifestyle choices and medical management for long-term brain health.
