WHO: Up to 45% of Dementia Cases Could Be Prevented or Delayed
The World Health Organization reports that nearly half of all dementia cases may be preventable through modifiable risk factors, as over 57 million people live with the condition globally.

Dementia could be significantly reduced in prevalence, with up to 45% of cases preventable or delayable through targeted public health interventions, the World Health Organization (WHO) has reported. The finding underscores growing evidence that modifiable risk factors play a substantial role in the development of dementia, a condition now recognized as the seventh leading cause of death worldwide.
According to WHO, more than 57 million people globally are currently living with dementia, with nearly 10 million new cases diagnosed annually. The condition is a major cause of disability and dependency among older populations, placing increasing strain on health systems and caregivers. Despite its growing impact, the report highlights that a substantial proportion of risk is linked to lifestyle and environmental factors that can be addressed through prevention strategies.
These risk factors include midlife hearing loss, low educational attainment, smoking, hypertension, obesity, physical inactivity, social isolation, and excessive alcohol use. Early intervention in these areas, particularly during midlife, may significantly reduce the likelihood of developing dementia later in life. The WHO emphasizes that public health policies focusing on these modifiable risks could alter the trajectory of dementia incidence globally.
"Up to 45% of dementia risk can be prevented or delayed," stated the WHO report, as cited by Channels Television and Premium Times. With dementia cases projected to rise in the coming decades, especially in low- and middle-income countries, the organization calls for integrated prevention strategies within national health frameworks.
The report aligns with broader global health efforts to shift focus from treatment to prevention in noncommunicable diseases. By addressing key determinants early, health systems may reduce the future burden of dementia, improve quality of life for aging populations, and promote healthier cognitive aging worldwide.
