The study, published in the Journal of the American Academy of Neurology, involved 11,709 people with a mean age of 54 who were followed for an average of 25 years.
Participants met up to five times with researchers during the course of the study. None had a history of heart disease or stroke at the beginning of the study.
"Orthostatic hypotension has been linked to heart disease, fainting and falls, so we wanted to do a large study to see if this form of low blood pressure is also related to problems in the brain, especially dementia," said Andreea Rawlings from the Johns Hopkins Bloomberg School of Public Health in the US.

The researchers found that those who had orthostatic hypotension at baseline had a 54 percent higher risk of developing dementia than those who did not have orthostatic hypotension at the beginning of the study.
A total of 999 of the 11,156 without orthostatic hypotension, or nine percent, developed dementia, compared with 69 of the 552 people with orthostatic hypotension or 12.5 percent.
In addition, those with orthostatic hypotension had twice the risk of ischemic stroke. A total of 15.2 percent or 84 out of 552 subjects with orthostatic hypotension had ischemic stroke, compared with 6.8 percent or 758 out of 11,157 people without orthostatic hypotension.
There was no association with bleeding.

"Further studies are needed to clarify what these compounds might cause and to investigate possible prevention strategies," she said.
