Alzheimer‘s causes may remain largely unknown, and clinical trials for an effective drug have so far been fruitless, but new international scientific research shows that high education reduces the risk of developing the disease by 11%.
Researchers from Sweden, Germany and the UK, led by Associate Professor Suzana Larson of the University of Stockholm’s Karolinska Medical Institute, who published the British Medical Journal “British Medical Journal”, analyzed data for approximately 17,000 Alzheimer patients and 37,200 healthy.
“Our findings provide the strongest evidence today that the higher educational level is associated with a lower risk for Alzheimer‘s disease. Consequently, improving the educational level can significantly reduce the number of people experiencing this catastrophic condition, “Larson said.
Scientists believe that higher education leads to thoughts and other cognitive functions that are more complex, with the result that man creates a “cognitive reserve” that helps prevent dementia in the elderly.
The brain has created more connections between its neurons, so when it is attacked by Alzheimer, it has alternative neural networks that can use it in place of the brain cells that are rotten. A similar ‘cognitive reserve’, apart from education, seems to create the greatest intelligence.
Alzheimer’s disease is the most common cause of dementia and the number of patients is constantly increasing internationally as the proportion of the elderly in the world population is growing more and more. People who are socially isolated, smoke, do not exercise, and generally have poor physical health, are more at risk from Alzheimer‘s.
