- Study finds that mental stimulation could delay the onset of dementia symptoms.
A new study has reportedly indicated that people with mentally stimulating occupations are at a lower risk of developing dementia in their later years as opposed to those who are in a non-stimulating job.
According to reports, scientists assessed more than 100,000 candidates in studies across the U.S., UK, and Europe, where they studied the links between job-based factors and mortality, disability, and chronic illness.
While cognitive stimulation is believed to postpone or avert the onset of dementia, until now studies were based on comparatively smaller sample sizes and short-term interventions extending inconsistent results.
Citing sources, cognitive stimulation at work was measured at the start of the trials and the participants were tracked for a period of 17 years to monitor any sort of development of dementia.
Professor Mika Kivimaki, lead author from the Institute of Epidemiology and Healthcare, University of London stated that the findings of the research support the long-standing hypothesis that effective mental stimulation during adulthood can help postpone the onset of dementia.
Prof. Kivimaki also highlighted that dementia levels among people aged 80 who experienced high levels of mental stimulation was noticed at age 78.3 in those who witnessed low mental stimulation. This indicated an average delay in the onset of the disease by about one and half years, however, there could be variation in the effect between people.
Kivimaki further mentioned in the main analysis that the data comprises of a wide range of occupations, but cognitive stimulation was carried out using self-reports instead of occupations.
Seemingly, under a supplementary analysis, a job-exposure matrix measurement was adopted for cognitive stimulation based on 87 different public-sector jobs.
Occupations with high cognitive stimulation included senior government officials, CEOs, directors, and production and operations managers.
On the other hand, jobs with low cognitive stimulation encompassed cashiers, fishery and related laborers, and mobile-plant operators.
For the record, factors like sex, age, education, lifestyle, and known dementia risk factors in adulthood and children were also taken into consideration.
