The World Health Organization (WHO) has published an updated edition of its guidance on reducing the risk of cognitive decline and dementia, encouraging people to adopt healthy lifestyle habits that support brain health throughout life.
The recommendations are intended to help governments, healthcare providers, and individuals understand evidence-based approaches that may lower the risk of developing dementia. While dementia cannot always be prevented, the WHO says certain lifestyle choices may help reduce the likelihood of cognitive decline in some people.
Healthy Lifestyle Habits Remain Central
According to the updated guidance, maintaining a healthy lifestyle plays an important role in supporting brain health. The WHO recommends:
- Eating a balanced diet rich in fruits, vegetables, whole grains, and healthy fats.
- Engaging in regular physical activity appropriate for age and health status.
- Avoiding tobacco use and limiting harmful alcohol consumption.
- Managing conditions such as high blood pressure, diabetes, and high cholesterol with the help of healthcare professionals.
- Staying socially active and participating in mentally stimulating activities.
The organization notes that these habits also contribute to overall physical health and may reduce the risk of other chronic diseases.
Understanding Dementia
Dementia is a group of conditions that affect memory, thinking, behavior, and the ability to perform everyday activities. Alzheimer’s disease is the most common form of dementia, although there are several other types.
The WHO estimates that millions of people worldwide are living with dementia, and the number is expected to increase as populations age.
Health experts stress that early diagnosis and appropriate support can help improve quality of life for people living with the condition and their caregivers.
Prevention Is Not Guaranteed
The WHO emphasizes that following healthy lifestyle recommendations does not guarantee that a person will avoid dementia. However, evidence suggests that addressing modifiable risk factors may reduce the likelihood of developing the condition in some individuals.
Experts also encourage people experiencing memory problems or changes in thinking to seek medical evaluation rather than self-diagnose.
Looking Ahead
The updated guidance is expected to inform public health policies and community health programs aimed at promoting healthy aging and reducing the global burden of dementia.
Researchers continue to study additional factors that may influence brain health and improve prevention and treatment strategies.
