Blood pressure and dementia risk share surprising link, study suggests

Hypertension, oregon precocious humor pressure, is known to person a nonstop interaction connected bosom onslaught and changeable hazard — but a caller survey has revealed its astonishing nexus to encephalon health.

In a large, randomized trial, researchers led by First Hospital of China Medical University discovered that "intensive humor unit control" resulted successful a 15% reduced dementia hazard among participants and a 16% reduced hazard of cognitive impairment.

The survey included 33,995 radical successful agrarian China aged 40 oregon older who had "uncontrolled hypertension."

The participants were divided into 2 groups. One received "usual care," portion the different was assigned to "trained non-physician assemblage healthcare providers" who prescribed "titrated antihypertensive medications."

For the second group, the medications helped them execute a systolic humor unit extremity of <130 mm Hg and a diastolic humor unit extremity of <80 mm Hg, according to the survey findings successful Nature Medicine.

"The superior result of all-cause dementia was importantly little successful the involution radical than successful the accustomed attraction group," the researchers wrote. 

They were besides little apt to acquisition "serious adverse events."

This was 1 of the archetypal large-scale, randomized, controlled effectiveness trials to show a "significant simplification successful all-cause dementia associated with lowering humor pressure," the researchers concluded.

There were immoderate limitations of the study, the nonfiction acknowledged, including the lack of baseline and follow-up cognitive assessments.

"Unlike studies performed successful the United States, this survey employed non-physicians to importantly trim humor unit successful agrarian China done a ‘cluster’ blinding method," Serwer, who was not progressive successful the study, told Fox News Digital.

"While the survey tin beryllium taxable to scrutiny, it raises a pertinent question: How important is modification of cardiovascular hazard factors successful the improvement of dementia?"

The superior medications utilized successful the survey to little humor unit were calcium transmission blockers and angiotensin receptor blockers, Serwer noted.

"These commonly prescribed medications person been independently associated with a reduced hazard of dementia, irrespective of the magnitude of humor unit simplification they achieve," helium said.

"This raises the anticipation that the little rates of dementia observed whitethorn beryllium attributed to different beneficial effects of the medications alternatively than solely to humor unit reduction."

To corroborate the findings, Serwer said it would beryllium beneficial to see baseline cognitive assessments of the patients and to place the prevalence of Alzheimer’s dementia wrong the communities.

"The astir important takeaway from this survey is the profound value of addressing humor pressure, cholesterol, smoking and sedentary lifestyles," the cardiologist said.
