Nearly Half of Dementia Cases Could Be Prevented or Delayed, Study Finds

A recent study published in the Lancet reveals that nearly half of dementia cases worldwide could be prevented or delayed by addressing 14 modifiable risk factors, The Guardian reported yesterday.

The number of dementia patients is expected to rise to 153 million by 2050, with global costs exceeding $1 trillion annually.

Researchers found that factors such as high cholesterol, untreated vision loss, low education levels, and physical inactivity contribute significantly to dementia risk. The report emphasizes that lifestyle changes, including regular exercise and cognitive activities, can lower risk and potentially delay onset.

Recommendations include improving access to hearing aids, vision screenings, and quality education. Implementing these public health interventions could save the UK £4 billion by reducing dementia rates. Experts stress that while age and genetics are significant risk factors, addressing lifestyle and societal issues presents a substantial opportunity for prevention and improved quality of life for individuals and communities.
