HealthGeekss | Sept 11,2019
High blood pressure may accelerate cognitive decline among adults or older e people, but treatment can slow down the decline.
Researchers of Columbia University said that both high blood pressure and cognitive decline are the two main symptoms of aging.
High Blood Pressure Influences Brain’s Capacity
According to the guidelines of American Heart Association issued in 2017, there are approximately 70 million people only in America and 1 billion people are affecting with high blood pressure worldwide.
While researchers are finding the link between high blood pressure and cognitive decline to examine how much high blood pressure affects brain’s blood vessels, which in turn affect memory, thinking and language skills.
For the Study, researchers analyzed the data of 11000 participants from 2011 to 2015 collected from China Health and Retirement Longitudinal Study( CHARLS) to study how treatment of high blood pressure may affect cognitive decline.
High blood pressure was defined as having a systolic pressure of 140 mmHg or higher and diastolic pressure of 90 mmHg or higher and taking anti-hypertensive medicine.
Researchers also asked participants about the treatment of high blood pressure, education level and also asked either they are living in urban or rural environment.
They also tested their cognition to evaluate the mental condition.
Cognition Rate Declined in 4 Years
During the four years follow-up period cognition rate declined. Participants showed a rapid cognition rate decline as compared to them who went under high blood pressure treatment or don’t have any kind of high blood pressure.
The rate of cognition decline was same for high blood pressure people who were treated and who were not affected with high blood pressure.
In the Conclusion,Shumin Rui, Author of the study stressed that there is need of more research to screed high blood pressure and some people are not aware they have high blood pressure which can be treated.
Additionally, We need to better understand how can we overcome the severity of cognitive decline, consequence of high blood pressure.
