A clinical study conducted in the United States has shown that people who have been intensively treated for hypertension less often develop mild cognitive impairment, which develops during the first stage of Alzheimer's disease.
The history of fighting Alzheimer's is full of hope and disappointment, so the results of the Sprint Mind study, published Monday in the Journal of the American Medical Association (JAM), should be treated with caution.
But the number of participants in the study and the good statistical quality of their results lend relevance to the research that first discovered a way to prevent problems with memory or concentration in the elderly.
“This is the first study that demonstrates an effective strategy for preventing age-related cognitive impairment,” said Christine Jaffe, a specialist in neurodegenerative diseases at the University of California, San Francisco.
The study involved more than 9,000 adults over 50 with hypertension. Half received treatment to reduce systolic pressure to less than 140 mm Hg. St., And the other half – to the level of less than 120 mm Hg. Art., More ambitious goal.
After a rough observation for five years, the doctors did not observe any difference between the two groups regarding "probable dementia."
However, the group with intensive treatment had significantly less "mild cognitive impairment."
Mild cognitive impairment is a stage that includes, in the opinion of the Alzheimer's Association, obvious difficulties in finding the right word or name, difficulty remembering the names of people who were recently found, or forgetting something immediately after reading.
All people with Alzheimer's disease have passed this stage, but not all people with mild cognitive impairment develop Alzheimer's disease.
Since the study is not conclusive that the treatment of hypertension will prevent Alzheimer's disease, the association will fund the extension of a two-year study to continue patient evaluation. (NA)
