Mental stimulation at work linked to lower dementia risk, a new study shows. Dementia affects more than 50 million people around the world.
The study investigated the association between cognitively stimulating jobs and a 23% lower risk of dementia than other people. However, previous studies have shown that staying mentally active during leisure time can help prevent dementia.
The findings of the latest study were published in the BMJ.
The researchers also discovered that people who have more mentally stimulating jobs have reduced levels of particular proteins that can increase the risk of dementia.
According to the Centers for Disease Control and Prevention (CDC), dementia include symptoms such as difficulty remembering, thinking, or making decisions.
The World Health Organization (WHO) notes that the condition affects more than 50 million globally and this number will likely be three times as high in 30 years’ time.
According to a 2020 report, the risk factors for dementia includes obesity, hypertension, hearing loss, traumatic brain injury, depression, smoking, physical inactivity, exposure to air pollution, social isolation, and diabetes.
Overall study results conclude that people who had cognitively stimulating jobs was at a 23% lower risk of developing dementia compared with people whose jobs were non-stimulating.
“While the jury is still out on the exact lifestyle “recipe” for dementia risk reduction, there are things we can do today that may decrease our risk of cognitive decline as we age. Eating a heart-healthy diet, exercising regularly, and staying cognitively engaged are just a few,” Dr. Claire Sexton said.
