Dementia Risk Declines in Younger Generations | Study
- A recent study indicates that younger individuals are experiencing a lower risk of developing dementia at any given age compared to older generations.
- The World Health Organization reported that in 2021,57 million people globally were living with dementia,with women being disproportionately affected.
- Australian researchers analyzed data from over 62,000 individuals aged 70 and older from the U.S., England, and Europe.
Younger generations are facing a reduced risk of developing dementia, a notable finding from a new study. The research reveals a positive trend: individuals today are less likely to experience dementia at the same age as previous generations,offering hope and highlighting progress in understanding this complex condition. This decline is particularly noticeable among women, with potential links to increased access to education and healthcare. Scientists are actively examining the factors behind this positive change, including improved health practices and treatments for related conditions. while the overall burden of dementia remains a concern due to aging populations,this research provides encouraging news.

Younger Generations Face Lower Dementia risk, Study Shows
A recent study indicates that younger individuals are experiencing a lower risk of developing dementia at any given age compared to older generations. This positive trend is especially apparent among women.
The World Health Organization reported that in 2021,57 million people globally were living with dementia,with women being disproportionately affected. while age is a notable risk factor, experts emphasize that dementia is not an unavoidable part of aging.
Australian researchers analyzed data from over 62,000 individuals aged 70 and older from the U.S., England, and Europe. The study,published in Jama Network Open,assessed participants’ cognitive abilities and daily activities to determine their likelihood of having dementia.
The findings revealed that while the prevalence of dementia increases with age across all generations, younger generations are less likely to develop the condition at the same age as their predecessors.
Dr. Sabrina Lenzen, a study co-author from the University of Queensland, noted the encouraging trend. “Younger generations are less likely to develop dementia at the same age as their parents or grandparents,” Lenzen said. She cautioned, however, that “the overall burden of dementia will still grow as populations age, and significant inequalities remain – especially by gender, education and geography.”
For example, in the U.S., 25.1% of those born between 1890 and 1913 had dementia between ages 81 and 85. In comparison,only 15.5% of those born between 1939 and 1943 developed the condition at the same age.
The researchers suggest that increased access to education for women in the mid-20th century may contribute to the more pronounced decline in dementia risk among women, particularly in Europe and England.
Tara Spires-Jones, director of the Center for revelation Brain Sciences at the University of Edinburgh, called the study well-conducted. “The number of people living with dementia is still increasing due to our ageing population, but this study adds to the good news that more recent generations have a decreased risk compared to past generations,” Spires-Jones said.
Spires-Jones also pointed to factors such as compulsory education, smoking bans, and improved medical treatments for heart disease, diabetes, and hearing loss as potential contributors to the decline.
David Thomas, head of policy and public affairs at Alzheimer’s Research UK, said evidence suggests nearly half of dementia cases could be prevented or delayed by addressing 14 key risk factors – from smoking to air quality.
What’s next
Experts emphasize the need for continued research to understand the factors driving this decline in dementia risk and to develop strategies for further prevention and treatment.
