According to the study’s authors, on-the-job intellectual stimulation appears to reduce levels of specific proteins that inhibit brain cells from establishing new connections, which might help prevent or delay dementia.
“This is a significant study that adds to the body of evidence suggesting that cognitive stimulation is beneficial to long-term brain health,” said Claire Sexton, director of scientific programs and outreach at the Alzheimer’s Association, who examined the findings.
An Intellectually Challenging Job May Be Beneficial In Preventing Dementia
It’s unclear how lifestyle and employment might help reduce dementia risk, but she believes that keeping your brain busy is an important component of keeping it healthy.
A multinational team compared dementia levels in persons who worked in mentally challenging professions to those who worked in less stimulating jobs.
Dementia is an ailment where the mental abilities are challenged with the increasing level of ailment. If one keeps himself busy with various activities that need mental focus it may help keep the mind alert for a long time and hence the effects of dementia may stay restricted.
This survey was conducted with a number of samples by experts of different ages and backgrounds. It helped them to know the effect of one’s activities on his brain and its reaction that can lead to a medical condition of the same.
According to the findings, intellectually engaging work can delay the development of dementia by two years. Lead author Mika Kivimaki, a professor of social epidemiology at University College, believes that mentally stimulating employment can delay the onset of dementia by two years.
His team emphasizes that this research does not prove that working in an intellectually engaging environment prevents dementia; rather, it shows that the two characteristics appear to be connected.
They’re ones that require difficult activities and decision-making, according to the researchers. Low demands and minimal job control characterize non-stimulating occupations.
“While the exact lifestyle recipe for dementia risk reduction is still unknown, there are things we can do now to reduce our risk of cognitive decline as we age,” she said. “A heart-healthy diet, frequent exercise, and remaining mentally engaged are just a few.”
Kivimaki’s team gathered information from approximately 108,000 men and women who participated in seven studies run by the IPD-Work collaboration, which includes 13 European organizations.
They also looked at mental stimulation and proteins in over 2,260 people from one research, as well as proteins and dementia risk in over 13,600 people from two additional investigations.
The researchers started by assessing mental stimulation at work and then tracked the participants for an average of 17 years.
They discovered that persons who worked in cognitively stimulating occupations were less likely to acquire dementia than those who worked in non-stimulating jobs, and this was true for both men and women. The link was stronger for Alzheimer’s disease than for other kinds of dementia, according to the study.
Lower levels of three proteins related to dementia risk were also connected to mental stimulation.
Even after researchers took into consideration dementia risk variables such as sex, education, and lifestyle, the findings persisted. Education has fewer advantages than the other variables. He believes it is essential to understand the biological foundation for these discoveries.
“However, the impact size of job stimulation is not significant and appears to be decreased when educational achievement is further considered,” Dikhtyar said, adding that dementia is not a certain conclusion.
“There are parts of our life that we can change to minimize our chance of developing the disease,” he added. “Continued participation in cognitively stimulating activities, beginning in school and continuing throughout one’s working life, might be one such preventative measure.”
