Dementia risk and early warning signs linked to metabolic health

New guidelines from the World Health Organization indicate that up to 45% of dementia risk is linked to modifiable factors, including hypertension, diabetes, physical inactivity, smoking, alcohol consumption, social isolation, and air pollution. Experts emphasize that metabolic health is crucial for brain function, as the brain relies on proper circulation and energy supply.

Early signs of cognitive decline can appear years or even decades before a formal diagnosis. Key early symptoms include difficulty remembering recent conversations, anomia (struggling to find familiar words), challenges with multi-step executive tasks like managing a budget, and noticeable changes in personality or mood. Early detection is considered vital for improving long-term health outcomes and quality of life for those affected.
