BLOOD PRESSURE: Better control decreases risk of dementia

-- Reduce your risk of dementia by lowering systolic blood pressure
High blood pressure, bad. Low blood pressure, good.
A recent study measuring the effects of lowering high blood pressure on dementia and/or cognitive impairment recorded results so dramatic that the monitoring board felt that it was unethical to continue the control group.
Such a shame, because while the study clearly benefitted the health of participants, its early termination ultimately failed to clinch what looked like a cut and dried conclusion.
With most studies failing to demonstrate a causative link between lowering high blood pressure and risk of cognitive impairment and dementia, scientists used meta-analysis to answer the question.
Researchers in Ireland appraised data from 14 studies comprising almost 100,000 participants and found that older individuals (average age 69) who lowered their blood pressure were slightly less likely to develop dementia or cognitive impairment (7.0% versus 7.5%).
There’s your answer.
