A study by researchers at Columbia University found that employment stability in midlife is associated with better preservation of memory and other cognitive functions as people age.

According to Alzheimer’s & Dementia, researchers reached this conclusion after analyzing data from more than 2,400 Americans over a 16-year period.
The researchers analyzed participants’ employment histories and assessed their cognitive functions.
They found that men who experienced employment instability scored lower on cognitive tests, showing signs of more pronounced brain aging equivalent to about seven additional years compared with expected levels.
Among women, memory and executive-function tests, which are associated with planning and decision-making, showed lower performance among those who retired early or experienced extended periods out of work. The researchers estimated that these characteristics were associated with about six additional years of brain aging.
By the end of the follow-up period, symptoms of mild cognitive impairment or dementia were reported in about 30% of women and 31% of men.
The researchers believe that continuity of employment, rather than a sense of job security, may be an important factor in maintaining cognitive health.
According to the researchers, regular employment during midlife may help maintain mental alertness and, consequently, be associated with slower age-related cognitive decline.
The scientists emphasized that the study demonstrates an association but does not prove that employment directly affects brain health. Other factors related to employment history and lifestyle may also influence cognitive health.
