Reply to comment by U_Care in Lowering blood pressure may prevent dementia. The study provides the highest grade of available evidence to show that blood pressure lowering treatment over several years reduces the risk of dementia, and we did not see any evidence of harm by Wagamaga
Exercise is important, there is no denying that, however, the effect on blood pressure is usually not clinically enough. Even in the study you cited the mean drop in systolic/diastolic was -4.8/-3.19, which is small. The study in this post uses a criteria of -10/-5 to barely squeak out statistically significant results and demonstrate a negative correlation with dementia. Furthermore, according to the CDC about half of those with uncontrolled hypertension are at 140/90. Exercise is often inadequate to control hypertension and medications are necessary limit morbidity.
