Large -scale studies on people in China show that lower hypertension reduces the risk of dementia and cognitive impairment.
Many research has been connected High blood pressure and dementia, which is also known as hypertension, is even greater.. Some studies show that the side effects of blood pressure treatment may be low in dementia.
now, Jiang he At the southwestern medical center of Texas University in Dallas, his colleagues directly investigated the effects of medicines that reduce blood pressure on dementia and cognitive impairment.
They studied 33,995 people in China, over 40 years old and high blood pressure. Participants were divided into one of the two random groups with an average age of about 63 years old.
The first group received three anti -blood pressure drugs, including ACE inhibitors, diuretics or calcium channel blockers on average, and ensures that blood pressure is actively maintained. They also coached their lifestyles that could help lower blood pressure, including home blood pressure monitoring, weight loss, alcohol and salt intake.
The other sets treated as a control have gained the same coaching, including a single drug on average, and more common treatment for the region.
48 months later, the participants tested blood pressure and used the standard questionnaire to measure signs of cognitive impairment.
Concerns about high blood pressure begin when a person’s systolic pressure exceeds 130 millimeters of mercury (MMHG) or exceeds the relaxation pressure above 80 mmHg. Blood pressure It is higher than 130/80.
On average, people who received a lot of drugs reduced blood pressure from 157.0/87.9 to 127.6/72.6 mmHg, and the control group decreased from 155.4/87.2 to 147.7/81.0 mmHg.
The researchers also found that 15 %of the drugs were diagnosed with dementia during the study compared to the control group, and 16 %found that they had cognitive impairment.
“The results of this study showed that blood pressure reduction was effective in reducing the risk of dementia in patients with high blood pressure.” “This proven arbitration must be widely adopted and expanded to reduce the global burden of dementia.”
“For many years, many people knew that blood pressure was a risk factor for dementia, which provided very powerful evidence for the clinical benefits of blood pressure reduction drugs. Zachaary Marcum At the University of Washington in Seattle.
Rajsha The treatment of hypertension in Rush University in Chicago is helpful to add evidence that it can help prevent dementia, but it is only one part of the dementia puzzle. This is because various factors affect the brain’s ability as our age goes up.
Shah said, “We need to treat hypertension for various reasons.
Marcum also says people need to think more extensively than blood pressure to avoid dementia. He says there is Other known risk factors This is associated with increasing risk of dementia, including smoking, non -activity, obesity, social isolation and hearing loss.
And at different stages of other lives, other factors are more influential. In order to reduce the risk of dementia, SHAH says, “There must be an overall approach for a lifetime.”
