Sharjah 24 / AFP:
In the United States, a clinical trial showed that people on intensive antihypertensive therapy had a lower risk of mild cognitive impairment, the first stage of Alzheimer's disease.
However, the history of research on this disease leads to a cautious approach to this study, which published the American newspaper "Gamma", entitled "Sprint Mind".
However, the large number of study participants and the high statistical quality of one of its findings will make it an important tool for finding the desired treatment for this disease that is so difficult today.
This experience is the first, which has concluded a way to prevent memory disorders, or in the home of the elderly.
Christine Yaff, neuroscientist specializing in neurodegenerative diseases, wrote at the University of California in San Francisco in an article published separately in the magazine as a first experiment, which showed an effective strategy against the prevention of cognitive impairment related to age .
The clinical trial involved more than 9,000 adults over 50 years old with hypertension, half of whom received treatment to reduce the level of systolic pressure "the first between the two numbers used to measure blood pressure "to less than 140 millimeters and to set a more ambitious goal. For the second half reduce the level to less than 120 millimeters.
After a follow-up period of 5 years on average, the doctors found no difference between the two groups in terms of measuring the "possible dementia".
On the other hand, the intensive group had lower levels of "mild cognitive impairment" than those in the other group.
According to the Alzheimer's Association, the slight decline in cognitive abilities raises obvious difficulties in choosing the appropriate words or names, as well as difficulties in remembering people's names shortly after meeting them or forgetting information after having them. read.
All people with Alzheimer's disease have gone through this stage, but this disease does not affect all people with cognitive impairment.
The study confirms the idea that "what works for the heart is also beneficial for the brain," according to Maria Carrio, scientific director of the Alzheimer's Association.
However, this study does not conclusively conclude that blood pressure treatment can prevent Alzheimer's disease and many more studies are needed to prove this connection. Maria Carrio announced that the association would fund an extension of this study for a period of two years to assess the condition of patients for a longer period. More advanced stages of life.
