By 2050, the number of people living with dementia worldwide is projected to exceed 150 million, posing an unprecedented challenge to global healthcare systems.
According to a paper published in the journal Neurology, reading, writing, and learning foreign languages reduce the risk of developing Alzheimer’s by nearly 40%. This study, conducted by scientists at Rush University Medical Center in Chicago, confirms a direct link between cognitive activity and the slowing of cognitive decline.
The research suggests that a person’s mental resilience in old age is the fruit of the intellectual environment they have been immersed in throughout their lives. An eight-year observation of 1,939 participants showed that access to literature, interest in educational resources from an early age, and foreign language acquisition are of crucial importance.
The study’s results regarding the delay of disease symptoms are particularly impressive:
-
In individuals with the highest levels of intellectual activity, Alzheimer’s symptoms appeared at an average age of 94.
-
This is 6 years later compared to those with a passive lifestyle.
-
In cases of mild cognitive impairment, the difference amounted to 7 years.
While the study does not prove a direct cause-and-effect relationship, post-mortem examinations confirmed that individuals with active mental lives maintained significantly better memory and thinking skills until death.
This discovery highlights once again that dementia is not an inevitable consequence of aging. Scientists are calling on governments to increase investment in educational programs, as fostering an interest in learning from an early age provides millions of people with a chance for dementia prevention in the future.
