An essential component of the NIA mission is the dissemination of information about research and aging-related topics to the general public, health professionals, the media, policymakers, and advocacy organizations. The Institute reaches out to the public through the NIA Web site, two Information Clearinghouses with toll-free numbers, and the NIHSeniorHealth Web site.
The NIA Web site, www.nia.nih.gov , offers information about NIA programs, research findings, grants and training opportunities, and public and professional education materials. The NIA Spanish-language Web site, www.nia.nih.gov/espanol  has information on a wide range of health topics, free publications in Spanish, and links to other health-related, Spanish-language Web sites.
The NIA Information Center, 1-800-222-2225, distributes a variety of public and professional education materials, including Age Pages on more than 40 health topics—from arthritis and diabetes to sleep and skin care. NIA’s evidence-based Exercise Guide provides simple, easy-to-follow exercises to improve endurance, strength, flexibility, and balance.
The Alzheimer’s Disease Education and Referral (ADEAR) Center , 1-800-438-4380, offers information on diagnosis, treatment, patient care, caregiver needs, clinical trials, and research related to Alzheimer’s disease.
www.NIHSeniorHealth.gov  is a collaborative effort with the National Library of Medicine . Based on research on cognition and aging, the site provides information on more than 30 health topics. Information is available in a variety of senior-friendly formats, including large print, open-caption videos, and audio versions.
