Part-Time Work Linked to Lower Dementia Risk in Older Adults, Study Suggests
Research indicates that remaining employed part-time into one's mid-seventies may reduce the likelihood of developing dementia by a significant margin.
Pensioners who continue to work part-time appear to have a 38 percent lower risk of developing dementia compared to those who retire completely, according to new research. Scientists suggest this may be due to sustained cognitive stimulation and social interaction.
The study, which tracked nearly 14,000 individuals, found that part-time employment until the mid-seventies was associated with a reduced risk of dementia. This protective effect was observed when compared to individuals who remained in full-time employment after retirement age or ceased working entirely in their fifties or sixties.
Dementia, an incurable condition affecting nearly one million people in the UK, is projected to impact 1.4 million by 2040. Previous studies have suggested that retiring completely can increase dementia risk by removing the daily engagement and cognitive challenges that can help ward off the condition.
Researchers from Washington University in St. Louis hypothesized that maintaining part-time work could mitigate this risk. Their findings, published in the online medical journal medRxiv, indicate that part-time work may offer a balance, providing cognitive stimulation and social interaction while also allowing for adequate rest and health-promoting activities. The study concluded that part-time employment is less detrimental to brain health than either full-time work or complete retirement.
