People who feel dizzy or light-headed when they stand up may have an increased risk of developing dementia years later, according to a new study.
The study has been published in Neurology, the medical journal of the American Academy of Neurology.
The condition, called orthostatic hypotension, occurs when people experience a sudden drop in blood pressure when they stand up.
The study found the link with dementia only in people who have a drop in their systolic blood pressure, not in people with only a drop in their diastolic blood pressure or their blood pressure overall.
