14 Modifiable Risk Factors Could Delay or Prevent Dementia, Experts Say

Dementia affects millions of people worldwide, with over 55 million cases recorded as of March 2023. The condition leads to a steady decline in memory, thinking, and daily functioning, deeply impacting both patients and their families. With an ageing global population, researchers are now focusing more on prevention and risk reduction.

Dementia is not a single disease but a broad term for disorders causing brain cell death and severe cognitive decline. Symptoms often include short-term memory loss, confusion, mood swings, and difficulties with movement. These changes gradually reduce independence and quality of life.

Recent studies have identified 14 modifiable risk factors linked to dementia. Addressing these—such as managing hypertension, diabetes, and maintaining an active lifestyle—can lower the chances of developing the condition. Experts emphasise that early intervention not only delays dementia but also improves overall health in later years.

As life expectancy rises, dementia cases are projected to grow significantly. This trend places greater pressure on healthcare systems and families. Prevention strategies, including lifestyle adjustments and medical management, are becoming increasingly important to slow the condition's progression.

Tackling risk factors like chronic health conditions and inactivity can help protect brain health as people age. These measures may reduce dementia cases while supporting longer, independent lives. With global numbers expected to climb, early action remains a key priority for individuals and health services.
