PHILADELPHIA: Those who experience a sudden drop in blood pressure upon standing are at increased risk of developing dementia, say researchers.
The condition — known as orthostatic hypotension — increases the risk of dementia, including Alzheimer’s, by 15 percent, according to a 24-year study of more than 6,000 people.
Orthostatic hypotension, which can trigger head rushes or dizzy spells upon standing, is known to cause reduced blood flow to the brain. Previous studies have shown that reduced blood flow in the brain, in the elderly, can contribute over time to brain dysfunction, but previous research hadn’t specifically examined any correlation between orthostatic hypotension and dementia.
