The study looked at (nearly) 400 men who developed Alzheimer's disease. It assessed the time they spent in full-time (education), the type of work they did and the point at which they retired.
The researchers (detected) no link between the onset of dementia and education or occupation. But they found that every extra year at work was (associated) with a six week delay in Alzheimer's. They say this (points) to the value of keeping the brain active by working.
They also acknowledge that the nature of (retirement) is changing, and for some people it may be as intellectually stimulating as working. The Alzheimer's Research Trust, which funded the study, says more people than ever (retire) later in life to avert financial hardship, but there may be a silver lining: lower (dementia) risk. However it says much more research is needed in order to understand how to delay or prevent dementia.
