Study Finds Almost Half of Dementia Cases Preventable or Delayed

A recent study by The Lancet commission has identified 14 modifiable risk factors that could prevent or delay nearly half of dementia cases worldwide. These risk factors include vision loss, high cholesterol, air pollution, and social isolation.

The study recommends public health interventions such as accessible hearing aids and vision screening, reducing harmful noise exposure, and providing good-quality education to children. Experts are calling for coordinated policies across health, research, and social sectors to address the growing dementia problem.

While the 45% reduction in dementia cases is an optimistic estimate, it highlights the possibility of dementia prevention. Taking care of heart health, through regular screening and a healthy lifestyle, can also protect brain health.

Individuals can also contribute to their brain health by consuming moderate amounts of alcohol, maintaining a healthy diet, and engaging in regular physical exercise. However, political efforts are also needed to ensure access to education and clean air globally.

The study emphasizes that although the number of dementia cases is increasing with an aging population, there are actions that can be taken to reduce the impact of this disease on individuals, families, and society as a whole.
