Keeping a diary is often seen as a teenage hobby—pages decorated with glittery pens. But research shows that that kind of writing can also help older adults reduce their risk of developing dementia.
Journaling and other literacy activities linked to lower dementia risk
Researchers analyzed data from 10,000 Australians aged 70 and older who were followed for nearly a decade. Those who took part more often in literacy-based activities—journaling, writing letters, or using computers—had an 11% lower risk of developing dementia.
Active mental activities like playing board games, cards, or chess and solving crosswords or puzzles were associated with a 9% risk reduction. Artistic activities such as woodworking, metalworking, or painting, along with passive mental activities like reading newspapers or listening to music, were linked to a 7% lower dementia risk. Social outings and conversations showed no measurable effect.
A team of researchers from Melbourne says these results show that adult participation in literacy activities, the creative arts, and both active and passive mental tasks can help lower dementia risk later in life. For older adults, enriching daily routines may be particularly important because lifestyle changes can influence disease development.
The team suggests a varied leisure life may reflect an optimistic personality and provide cognitive benefits. That stimulation promotes the growth of neurons and synapses and supports overall well-being.
Dementia’s prevalence and the search for treatments
The research team added that their findings could help shape geriatric care policies and dementia-prevention strategies for older adults. The WHO estimates about 50 million people worldwide live with dementia, with nearly 10 million new cases each year.
Estimates from a 2021 study suggest the number could exceed 152 million by 2050 as populations age. Experts predict the fastest growth in prevalence will be in Eastern and Northern Africa and the Middle East.
As reported by the Daily Mail, scientists are exploring a potential treatment for dementia. Research shows the protein “Klotho” rejuvenates the brains of older monkeys, and it might have similar effects in humans. Still, creative methods to help prevent dementia are already available and can be beneficial for older adults today.
