A groundbreaking study published in the journal *The Lancet* offers a glimmer of hope in the fight against dementia, a debilitating condition affecting millions worldwide. The study revealed that addressing 14 modifiable risk factors could potentially prevent or delay nearly half of all dementia cases.
The study, conducted by an international team of researchers, builds on previous research published in 2017 and 2020. It identified 12 previously known potentially modifiable risk factors and added two new ones: vision loss and high levels of low-density lipoprotein (LDL) cholesterol, often referred to as “bad” cholesterol.
The research found that collectively addressing these 14 risk factors could lead to a 45% reduction in dementia prevalence globally. The impact could be even more significant in low- and middle-income countries, where dementia prevalence and health disparities are higher.
The report also highlighted the potential benefits of reducing these risk factors on overall health and well-being. It suggested that reducing dementia risks can increase healthy years of life and minimize the duration of poor health associated with dementia.
The study emphasizes the importance of preventive measures throughout the lifespan. It outlines a comprehensive program that includes:
*
Early Life:
Improving general education*
Midlife:
Addressing hearing loss, high LDL cholesterol, depression, traumatic brain injury, physical inactivity, diabetes, smoking, hypertension, obesity, and excessive alcohol consumption.*
Later Life:
Reducing social isolation, air pollution, and vision loss.The report also underscores the importance of supporting people living with dementia and their caregivers through evidence-based approaches and non-pharmacological interventions such as engaging in activities tailored to individual interests and abilities.
While the study offers promising results, it acknowledges that further research is needed to confirm the causal relationship between risk factors and dementia and to develop effective strategies for implementing preventive measures on a global scale. Nevertheless, the study serves as a crucial roadmap for policymakers, clinicians, and individuals to take proactive steps in the fight against this devastating disease.
