Blood pressure linked to dementia

Researchers claim that middle-aged individuals suffering from hypertension are six times more prone to developing memory problems.

According to a study conducted by the Alzheimer's Society, high blood pressure increases the risk of vascular dementia, the second most common memory problem after Alzheimer's, by 600 percent.

Scientists believe that treating high blood pressure in the elderly not only reduces the risk of heart disease, stroke and kidney damage but also lowers the dementia risk.

A similar study published in the Lancet Neurology journal showed that treating blood pressure patients with a diuretic with or without an ACE inhibitor reduces the risk of death due to stroke or other causes.

The study also reported that blood pressure drugs reduce elderly dementia risk by 13%.

Previous studies had reported that a low-salt diet and exercise along with taking appropriate medication and quitting smoking can effectively lower blood pressure.
