More Evidence That Education May Protect Against Dementia

TUESDAY, March 8, 2022 (HealthDay News) —

Not everyone who becomes forgetful with age develops dementia. And a new study shows that people with college degrees and advanced language skills are more likely to recover. Mild cognitive impairment (MCI) is an early-stage memory loss marked memory lapses. And problems with thinking that do not interfere with daily life. While people with MCI are more likely to develop dementia than people. Some do not have these early memory lapses, some do improve and return to normal. “While many people assume that if they develop mild cognitive impairment. They will inevitably turn into dementia, we found encouraging evidence that this is not the case.” Said study author Suzanne An assistant professor of public health at the University of Waterloo in Ontario, Canada.

Education and language skills can help predict who will develop dementia and who will not. Study found.

“These factors reflect brain workload, and our work suggests they may be indicators of cognitive reserve.” This said. But just how mental account permits defend against dementia is not previously completely comprehended.

“One possible mechanism is neural compensation. In which the brains of people with higher levels of the cognitive reserve may use alternative brain networks. Be better able to compensate for brain changes that initially led to mild cognitive impairment,” Taya’s explained. Researchers analyzed data from 619 American Catholic nuns aged 75. And older in a long-term study of aging and Alzheimer’s disease. The nuns were subjected to memory and other intelligence tests for up to 12 years or until death.

A total of 472 women were diagnosed with MCI during the study. And about a third (143) regained normal memory levels at least once within an average of 8.5 years of diagnosis. Nearly 84% of these 143 nuns never had dementia. Another third developed dementia, never returning to normal thinking and memory. While 3% remained at the MCI stage, and 36% of the nuns died.

Participants who received a bachelor’s degree were more than twice as likely. To regain their memory compared to those who received primary or secondary education. The study found that nuns who had a master’s degree or more advanced education were more likely. To regain their normal thinking skills after being diagnosed with MCI.

The results also give confidence to people who do not have such high levels of formal education, Taya says.

The study found that language skills, including those reflected in high grades in English classes or strong writing skills, also protect against dementia. Those who scored high in English but not in other subjects were almost twice as likely to improve after MCI than to develop dementia. What’s more, participants with strong writing skills, based on the number of ideas expressed, were four times more likely to improve than to develop dementia, the study found. According to Taya, this effect was even stronger for those whose writing used complex grammatical structure.

“Language is a complex brain function, so it makes sense that strong language skills were also protective, and this effect was even stronger than in the case of education,” Tayas said. In addition to a high level of education and strong language skills, nuns under 90 who do not have certain genetic risk factors associated with Alzheimer’s disease the most common type of dementia, are also more likely to see their memory return.

essence? “Reassuringly, our results show that there are many factors that increase your chances of recovering cognitive function after mild cognitive impairment,” Tayas said.

  • The findings were recently published online in the journal neurology .
  • Dr. Kenneth Langa, a dementia researcher at the University of Michigan at Ann Arbor, called the study “interesting and well done.”
  • Many people with MCI recover on their own, said Langa, who was not involved in the study.
  • “These results are consistent with other studies, but the careful measurement of this study and the long follow-up period provide additional confidence in the results,” he said.
  • These findings should be taken into account when treatment considerationLanga said.
  • “The fact that a significant number of people with MCI will not develop dementia even in the absence of any treatment increases the risk of overdiagnosis and potential overtreatment among people with MCI,” he said.
