Dementia Paused By Long Working Life?
21 05 2009More Work, Less Dementia?
Research suggests that working as late in life as possible may be effective in avoiding diseases such as Alzheimer’s according to research conducted by the Institute of Psychiatry at King’s College London.
Researchers have studied 1,320 dementia patients, including 382 men, and found that men who continued to work late in life helped keep their brains sharp enough to delay dementia.
Approximately 700,000 people in the UK have dementia. Experts currently believe that by 2051 as many as 1.5 million could suffer from the disease, which costs the country’s economy around £17 billion each year.
Dementia is believed to be caused by a mass loss of brain cells. Experts think that there is only one way to guard against it – build up as many connections between cells as possible by being as mentally active throughout life as possible – Cognitive reserve.
Past evidence shows that a good education can reduce the risk of dementia, and the latest study supports the idea that mental stimulation that continues until late in life reduces the risk of dementia.
It seems that those that opted to retire lat have developed Alzheimer’s at a later stage in life compared to those who left work early. Each additional year of employment is thought to add approximately six weeks before the onset of the disease.
One of the researchers involved says: “The possibility that a person’s cognitive reserve could still be modified later in life adds weight to the ‘use it or lose it’ concept where keeping active later in life has important health benefits, including reducing dementia risk.”
More Work To Confirm Results
Professor Lovestone adds: “The intellectual stimulation that older people gain from the workplace may prevent a decline in mental abilities, thus keeping people above the threshold for dementia for longer.”
But more research is needed to be sure of the results and prevent dementia completely.
The chief of the Alzheimer’s Research Trust which funded the research says: “More people than ever retire later in life to avert financial hardship, but there may be a silver lining – lower dementia risk.”
Though the small sample size of the study makes it difficult to draw firm conclusions from the study.
Dr Sorensen from the Alzheimer’s Society says: “There could be a number of reasons why later retirement in men is linked to later onset of dementia.
“Men who retire early often do so because of health conditions, such as hypertension or diabetes, which increase your risk of dementia.
“It could also be that working helps keep your mind and body active, which we know reduces the risk of dementia.”
A Spokesman for the Department for Work and Pensions said: “Not only can it mean more income, but social networking has increases activity.
“We also find that many of today’s older workers are choosing rejecting the cliff edge between work and retirement in favour of a gradual step down. And employers should help them do this.”
