There are many different underlying causes of vertigo, but it now seems like one of the most serious of these is so brief that many people don’t take it particularly seriously.
It lasts for only a second or two in most cases and people tend to ignore it and pass it off as normal.
It is related to the extreme dizziness that some people feel when they stand up after sitting or lying down.
When you stand up from sitting or lying down, your body needs to increase your blood pressure for a moment to ensure that enough blood reaches your brain against the gravity you have suddenly imposed on it.
But sometimes something goes wrong and extreme dizziness happens.
This condition is called orthostatic hypotension. It happens because their blood pressure drops by at least 20 mmHg systolic points or 10 mmHg diastolic points.
But if the blood vessels in your lower body do not constrict fast enough to increase your blood pressure for that moment, the blood cannot leave your lower body fast enough to go back up to your heart.
This means that there isn’t enough blood available for your heart to pump up to your brain, and your brain starts to cut out until enough blood arrives.
But scientists now suggest that middle-aged people who suffer from this condition may be at higher risk of dementia as they age. This study was published in the journal Circulation.
The scientists analyzed information collected by the Atherosclerosis Risk in Communities population-based study, involving 11,503 participants between 45 and 64 who had no history of coronary artery disease or stroke.
These participants were visited for the first time in 1987 and then observed for the following 20 years.
Researchers measured participant blood pressure when they got up after lying down for 20 minutes.
Scientists discovered that those who met the requirements for orthostatic hypotension were 40% more likely than the others to develop dementia, and had 15% more cognitive decline than the others had.
So what can you do to prevent bad events and deadly consequences of orthostatic hypotension?
Drink enough water to ensure that you have enough blood circulation through your body to maintain a healthy blood pressure. Avoid diuretics like blood pressure medications, excessive caffeine, and alcohol.
Some medications like antidepressants and alpha-1 blockers can also cause it.
