Any sudden drop in blood pressure in middle-aged people, which makes them deaf, dizzy or dizzy when getting up, could be a sign of an increased risk of dementia or dementia. stroke later, say the researchers. The results suggest that people who have experienced a drop in blood pressure – known as orthostatic hypotension – have a 54% higher risk of developing dementia.
They have also been found to be twice as likely to develop ischemic stroke, which occurs when a blood vessel carrying blood to the brain is blocked by a blood clot.
"Orthostatic hypotension has been linked to heart disease, fainting and falls, so we wanted to conduct a large study to determine if this form of hypotension was also related to brain problems, in especially dementia, "said Andreea Rawlings, of Johns Hopkins University of Maryland.
For the study, published in the journal Neurology, the team badyzed data from 11,709 people of an average age of 54 years, which were followed for 25 years on average.
Participants were asked to lie down for 20 minutes then to get up from a gentle movement and
A total of 999 of 11,156 without orthostatic hypotension, or 9%, developed dementia, compared with 69 of 552 persons with orthostatic hypotension, or 12.5%.
, a total of 15.2%, or 84% of 552 people, with hypotension orthostatic had ischemic stroke, compared to 6.8%, or 758 of 11,157 people without orthostatic hypotension.
"The measurement of orthostatic hypotension in middle-aged people could be a new way of identifying people who need to be closely monitored for dementia or stroke" says Rawlings.
