High blood pressure is well known to be linked to an increased risk of heart disease or stroke. It does, however, increase the risk of vascular dementia, which is the second most common form of dementia.
When a stroke blocks an artery in the brain, vascular dementia is common. Strokes, though, aren’t the only source of this disease. When blood vessels are weakened, vascular dementia may develop. This decreases brain blood flow, depriving the brain of essential oxygen and nutrients.
Researchers looked at the medical history of over four million individuals in a recent study. What they discovered is disturbing…
Between the ages of 30 and 50, higher blood pressure was linked to a 62 percent increased risk of vascular dementia!
“High blood pressure has long been known to increase the risk of stroke and heart disease. Professor Kazem Rahimi, the study’s lead scientist, says, “Our analysis has found that elevated blood pressure is often associated with a substantially higher risk of vascular dementia.”
Here are some of the study’s highlights:
- The George Institute’s study unit looked at the medical history of over 4 million individuals.
- About 11,000 of those individuals developed vascular dementia over a seven-year year
- Between the ages of 30 and 50, patients with hypertension have a 62% increased chance of vascular dementia.
- High blood pressure patients aged 51 to 70 have a 26% higher risk.
- Also after adjusting for the presence of stroke, high blood pressure remained a risk factor.
“Our results show that reducing blood pressure, either by exercise, diet, or blood pressure lowering medications, may minimize the likelihood of vascular dementia,” Professor Rahimi concludes.
