New research boosts the “use it or lose it” theory about brainpower and staying mentally sharp. People who delay retirement have less risk of developing Alzheimer’s disease or other types of dementia, a study of nearly half a million people in France found.
It’s by far the largest study to look at this, and researchers say the conclusion makes sense. Working tends to keep people physically active, socially connected and mentally challenged — all things known to help prevent mental decline.
“For each additional year of work, the risk of getting dementia is reduced by 3.2 percent,” said Carole Dufouil, a scientist at INSERM, the French government’s health research agency.
Researchers used these records on more than 429,000 workers. They were 74 on average and had been retired for an average of 12 years.
Nearly 3 percent had developed dementia but the risk of this was lower for each year of age at retirement. Someone who retired at 65 had about a 15 percent lower risk of developing dementia compared to someone retiring at 60, after other factors that affect those odds were taken into account, Dufouil said.
To rule out the possibility that mental decline may have led people to retire earlier, researchers did analyses that eliminated people who developed dementia within 5 years of retirement, and within 10 years of it.
