The World Health Organization (WHO) has announced that as much as 45 percent of dementia risk can be prevented or delayed by addressing modifiable factors such as tobacco use, excessive alcohol consumption, and physical inactivity.
Understanding Dementia's Global Impact
While there is no cure for dementia, up to 45 percent of the risks can be attributed to modifiable risk factors such as tobacco, alcohol use, social isolation, physical inactivity, air pollution and noncommunicable diseases (NCDs), including high blood pressure and diabetes.

- Over 57 million people live with dementia globally.
- Nearly 10 million new diagnoses occur each year.
Dementia ranks as the seventh leading cause of death worldwide, significantly affecting the quality of life for millions. According to the WHO, Alzheimer’s disease constitutes 60 to 70 percent of dementia cases.
Devora Kestel, director of the WHO's NCDs and mental health department, emphasized that these figures represent real individuals and families facing complex challenges.
In response to the growing evidence surrounding dementia risk factors, the WHO has updated its guidelines for health workers and policymakers. These recommendations are designed to promote early awareness and intervention.
Tedros Adhanom Ghebreyesus, the WHO chief, highlighted the importance of translating knowledge about dementia risks into immediate action for countries. The guidelines focus on prevention as the most effective method to combat rising dementia rates.
Key recommendations include:
- Cognitive stimulation and training for adults with mild cognitive impairment.
- Better management of hypertension, diabetes, and high cholesterol.
The WHO also called for stronger integration of services for noncommunicable diseases, mental health, and brain health. Investments in these areas are projected to yield significant economic returns, given that dementia costs the global economy approximately $1.3 trillion annually.
By understanding and addressing risk factors, the WHO believes that individuals can improve their health, maintain independence, and enhance their quality of life.
