Middle-aged people who feel dizzy when standing may have an increased risk of dementia.
A new study has found that middle-aged people who feel dizzy when standing up may be more likely to develop dementia as they get older. A team of researchers at John Hopkins Bloomberg School of Public Health looked at data from nearly 12,000 people in their mid-fifties over a 25-year period. When meeting with the participants in person, they had them lie down for 20 minutes and then stand up very quickly. Nearly five percent of the participants were found to have orthostatic hypotension (which is that feeling of dizziness when you stand).
At the end of the study period, they found that those with orthostatic hypotension had double the risk of ischemic stroke (which affects parts of the brain) compared to those who didn't experience dizziness or lightheadedness when standing. These findings suggest that measuring hypotension may be a good marker of both stroke and dementia but more research is needed to really determine the full scope of this connection.
