Your Country May Influence Your Dementia Risk More Than You Think, Study Suggests

A new study has challenged long-held beliefs about <a href="https://www.healthandme.com/health/dementia">dementia</a>, suggesting that your location may have a significant impact on whether you may or may not develop neurodegenerative disease.

Researchers from the University of Southern California studied health data from more than 214,000 adults across 21 countries.

They found that while many well-known <a href="https://www.healthandme.com/health/dementia">dementia</a> risk factors are universal, their impact can vary significantly depending on a person's country.

The findings suggest that prevention strategies should be customised to local populations rather than relying on a one-size-fits-all approach.

The researchers discovered that factors like education, obesity, hearing loss, smoking, hypertension, diabetes, depression, and physical inactivity do not contribute equally to <a href="https://www.healthandme.com/health-news/american-pro-football-players-4-times-more-likely-to-die-from-diseases-like-als-dementia-parkinsons-study-article-155022889" data-type="tilCustomLink">dementia </a> risk across the globe.

In some countries, less education emerged proved to be a strong factor, while in others, cardiovascular health or mental health played a larger role. 

"Our findings show that dementia prevention isn't one-size-fits-all," the researchers said, emphasizing that risk profiles differ substantially between countries and should inform future public health policies. 

Despite these regional differences, the study also identified encouraging similarities. Several modifiable risk factors consistently influenced dementia risk across multiple countries, reinforcing the importance of maintaining <a href="https://www.healthandme.com/health-wellness/challenge-your-brain-to-keep-it-young-new-study-says-learning-another-language-can-help-article-154975699" data-type="tilCustomLink">healthy lifestyles</a> while allowing governments to prioritize interventions based on local needs.

"Reducing dementia risk requires not only individual action but also supportive systems and policies that shape people's everyday lives," the WHO says.

The new research strengthens that message by suggesting that a country's healthcare system, education policies, environmental conditions, and socioeconomic circumstances may all influence how dementia develops within its population.

Experts say that these findings could help in designing effective prevention strategies. 

For example, countries where hearing loss has a stronger association with dementia may benefit from expanding hearing screening and access to hearing aids, while others might achieve greater impact by improving cardiovascular care, promoting physical activity, or expanding mental health services. 

Previous research has estimated that nearly 45% of dementia cases could potentially be delayed or prevented by addressing modifiable risk factors, including controlling blood pressure, managing diabetes, staying physically active, treating hearing loss, avoiding smoking, and maintaining social life.

Dementia is an umbrella term used to describe a significant decline in mental function that is serious enough to affect everyday life. 

It commonly impacts memory, thinking, and reasoning skills. Dementia itself is not a single disease, but a collection of symptoms caused by underlying conditions such as <a href="https://www.healthandme.com/health-wellness/normal-ageing-or-alzheimers-doctors-explain-six-key-differences-to-watch-for-article-154962355" data-type="tilCustomLink">Alzheimer’s disease </a> or vascular dementia.

<ul><li>Memory problems</li><li>Confusion</li><li>Difficulty finding words</li><li>Changes in mood or behavior</li><li>Trouble completing familiar tasks </li></ul>

The findings come as dementia continues to pose a growing global health challenge. According to the World Health Organization (WHO), dementia affects more than 55 million people worldwide, with nearly 10 million new cases diagnosed each year. 

WHO also notes that factors like poverty, limited access to education, healthcare inequality, and employment opportunities can significantly shape an individual's dementia risk.
