Preventing Dementia – Is It as Simple as Working Longer?

Once the magic word was plastics. Today, however, the magic advice might lie in a two word phrase:

Keep working.

According to recent research, it turns out that the solution to preventing dementia might well be the very same one proffered to help our underfunded social security system remain solvent.

Yes, it might be time to forget about retiring early. Heck, it might just be time to forget about retiring period.

Mental Activity Is Critical

It has long been suspected that those who remain mentally active later in life may be able to postpone and/or lessen the effects of Alzheimer’s. While that notion has spawned a whole industry devoted to brain fitness, it turns out that simply working later in life might be that ticket to warding off the effects of the debilitating disease.

That fact came as a result of the research of the Institute of Psychiatry at King’s College London. Experts took a look at more than 1,320 dementia patients, approximately 30% of them men.

Those who retired later in life developed Alzheimer’s at a later stage. As a simple association, for each additional year of employment there was about a six week later age of onset of the disease.

Use It or Lose It

There is a growing body of evidence pointing to the concept of cognitive reserve. For example, research shows that a quality education correlates to a reduced risk of dementia.

What is still unknown is whether we can continue to create cognitive reserve later in life or if by remaining mentally active we are able to preserve that brain status for a longer period. But the new philosophy of use it or lose it has moved from the world of physical fitness into the mental health field.

The study reveals that brain fitness may be maintained simply by the stimulation of the work environment.

Still, there were no findings to suggest that working longer would end the risk of Alzheimer’s. And others, like Dr Susanne Sorensen, head of research at the Alzheimer’s Society, noted that the study’s small sample size minimizes the ability to draw firm conclusions.

“There could be a number of reasons why later retirement in men is linked with later onset of dementia,” Sorenson told the BBC. “Men who retire early often do so because of health conditions, such as hypertension or diabetes, which increase your risk of dementia.”

Time to Keep Working?

Sorenson went on to add that working helps keep your body active as well, another key factor to reducing the risk of dementia.

One aspect that was mentioned but received little discussion is that it might well be time to put an end to the notion of working full time until that one magic day when a person draws the retirement line. Currently, for many the process is a precipice that marks the end of the world of work and the start of the retirement years.

It would stand to reason that for a vast array of reasons, financial, societal (social security and medical impact), as well as mental, the shift away from the work world should be more gradual. Instead of calling it quits one day, older workers should be able to reduce both their weekly and their yearly number of hours on the job in a more gradual manner.
