People who have a condition which causes them to feel dizzy when they stand may be almost 40 percent more likely to develop dementia compared with those who don’t, according to a study.
The authors of the paper published in the journal Neurology wanted to explore whether what is known as orthostatic hypotension could predict a person’s chances of getting dementia.
Orthostatic hypotension is where a person’s blood pressure drops significantly when they stand up, and has a range of causes. The most common symptom is feeling light headed when standing up.
The study involved 2,131 people aged 73 years old on average. Repeatedly over a period of five years, researchers tested their blood pressure after they stood up, and asked them to complete a cognitive test.
Blood pressure is measured in two ways: Systolic, or the pressure in the arteries when the heart beats and fills up with blood, and the diastolic, or the pressure in the arteries when the heart is resting between beats. The normal range for blood pressure is less than 120 systolic and less than 80 diastolic.
