The effect of high blood pressure on the brain and its relationship with dementia was discovered for the first time

High blood pressure has become a common disease and it is estimated that 30% of the world’s population suffers from it. Now, for the first time, researchers have found out what parts of the brain this disease damages and have found its possible role in the decline of mental mechanisms and the occurrence of dementia.

A group of researchers from the University of Edinburgh and the Jagiellonian University College of Medicine in Poland, using various methods such as brain MRI, genetic analysis and observational data from more than 30,000 people in the British Biobank study, tried to answer the question of whether hypertension really It causes important changes in the brain or not.

This study showed them that 9 sections From the brain including Putamen (round structures in the subfrontal part of the brain that are responsible for regulating movements and affecting various learning mechanisms), anterior thalamic fibers, anterior radial crest and anterior organs of the internal capsule, which are areas of white matter With the possibility of establishing communication between different parts of the brain, they are affected by high blood pressure.

Although Anterior thalamic fibers They are involved in performing executive functions, including planning simple and complex daily functions, but the other two parts that we mentioned above are involved in decision making and emotion management.

Examining the brain of patients with high blood pressure in order to prevent dementia

“By looking at these specific parts of the brain, we may be able to predict which hypertensive patients will develop memory loss and dementia sooner,” said one of the study’s senior researchers. This mechanism to Careful selection of medications “It will help us to have more serious treatments and prevent cognitive problems in people who are most at risk.”

Of course, researchers have noted that most of the people in the British Biobank study were white and middle-aged, as a result, these results may not be generalizable to all people in the world. The results of this research have been published in the European Heart Journal.
