Dementia risk may be cut by lowering blood pressure: study


A brand new study of greater than 28,000 folks supplies proof that lowering blood stress later in life can cut back the risk of dementia, researchers say.

The study from the Australia-based George Institute for Global Health checked out people from 20 nations with a median age of 69 and a historical past of excessive blood stress.

“We found there was a significant effect of treatment in lowering the odds of dementia associated with a sustained reduction in blood pressure in this older population,” Dr. Ruth Peters, affiliate professor on the University of New South Wales and program lead for dementia on the George Institute, stated in a information launch, noting that any preventative measures for dementia are a welcome step ahead.

According to the discharge, dementia impacts an estimated 50 million folks worldwide, a quantity projected to triple by 2050 on account of getting old populations. The Alzheimer Society of Canada estimates that almost 956,000 folks in Canada will be residing with dementia in 2030.

“Given population ageing and the substantial costs of caring for people with dementia, even a small reduction could have a considerable global impact,” Peters stated. “Our study suggests that using readily available treatments to lower blood pressure is currently one of our ‘best bets’ to tackle this insidious disease.”

Dementia is a deteriorating illness that quickly decays the recollection and psychological state of the particular person with it.

To look at the connection between blood stress and dementia, researchers analyzed 5 double-blind placebo-controlled randomized trials that used completely different blood pressure-lowering remedies and adopted sufferers till the event of dementia.

According to the report, many research beforehand regarded on the well being advantages of decrease blood stress however not the way it impacts the risk of dementia. Researchers hope the outcomes will equip public well being establishments with the instruments to scale back dementia throughout communities.

However, the analysis nonetheless leaves some unanswered questions.

“What we still don’t know is whether additional blood pressure lowering in people who already have it well-controlled or starting treatment earlier in life would reduce the long-term risk of dementia,” Peters stated.


This discovery is essential to Canada since a separate report by CanAge, a nationwide seniors’ advocacy group, famous the nation will face an inflow of dementia sufferers giant sufficient to overwhelm its health-care system between now and 2050.

According to the report, the risk of dementia doubles at age 85 to 25 p.c and with greater than seven million Canadians over the age of 65 as we speak, the interval to organize is diminishing quickly.

Part of the issue lies with the variety of health-care professionals skilled to diagnose dementia early in older adults. In 2016 solely two out of 5 medical doctors felt they had been ready to handle neighborhood dementia care.

Canada launched a nationwide dementia technique in 2019, certainly one of solely 39 United Nations member states to take action.
