Risk reduction of cognitive decline and dementia: WHO guidelines, second edition

by World Health Organization

About this book

This World Health Organization guideline examines approaches to reducing the risk of cognitive decline and dementia. The second edition updates the evidence behind recommendations on physical activity, diet, tobacco and alcohol use, and the management of health conditions associated with cognitive health. Its intended readers include health professionals, programme managers, and people developing prevention services.

The publication explains how the evidence was reviewed and how recommendations were developed, with discussion of implementation and research priorities. Expanded material considers sensory impairment, sleep, air pollution, and interventions that combine several approaches. The complete 2026 guideline retains its evidence summaries, references, contributor records, and links to separately published supporting web annexes.
