In contrast to the research on orthostatic hypotension, lowering blood pressure in people without the condition may defend against the development of dementia. This new research was announced at the Alzheimer’s Association International Conference. A group of 9300 people with high blood pressure were split not two groups: group one was asked to take two medications to lower blood pressure, whereas group two was asked to take three, with the intent of lowering their pressure reading below 140 and 120 respectively. They found the group who aimed for the lower blood pressure had a reduced risk of mild cognitive impairment by 19 percent. Mild cognitive impairment tends to precede a dementia diagnosis and thus may be more important to protect against. The study does not test specific drugs, instead, the medications were determined on an individual basis by each participants doctor. More research needs to be done as these results are considered preliminary.
