The National Institute of Neurological Disorders and Stroke (NINDS), a part of the National Institutes of Health, is the leading U.S. federal government agency supporting research on brain and nervous system disorders. It provides the public with educational materials and information about these disorders.

This not-for-profit organization provides support services and information on holistic, alternative, and conventional medical care options for people with multiple sclerosis (MS). It does not endorse any single health care approach but provides information on all. It publishes a quarterly newsletter.

The Multiple Sclerosis International Federation (MSIF) was established in 1967 as an international body linking the activities of national MS societies around the world. The website has information about multiple sclerosis, how to find support (including maps with lists of MS societies around the world), how to get involved, stories from people with MS, research news, and other resources.

This organization has many resources for people with multiple sclerosis (MS). It provides referrals to neurologists and other health professionals, physical activity programs, and affiliations with 80 MS treatment centers throughout the United States. It operates counseling services at the chapter level and assists in family and social support, independent living, and referrals to long-term care facilities. It compiles current research reports, publishes pamphlets and the Inside MS magazine for consumers, and has a network of over 140 local chapters and related support groups.
