Alzheimer's disease is less likely to affect people who work beyond the normal retirement age, according to a report in the International Journal of Geriatric Psychiatry.
And much of that may be down to keeping mind and body active for longer, says Dr Susanne Sorensen, head of research at the Alzheimer's Society.
She points out that early retirement is often precipitated by health conditions such as diabetes or high blood pressure, which increase the risk of dementia.
In the next 10 years, she says, one million people will be affected by the condition. She adds: "It could also be that working helps keep your mind and body active, which may reduce risk of dementia.
"The best way to reduce your risk of dementia is to combine keeping physically active with eating a balanced diet and getting your blood pressure and cholesterol checked regularly."
She was commenting on research led by Michelle Lupton, from the Institute of Psychiatry at King's College, London.
