The Transverse Myelitis Association (TMA) is a non-profit, self-help organization dedicated to providing mutual support to persons affected by transverse myelitis. Transverse myelitis is an acute spinal cord inflammation involving both sides of the spinal cord. Transverse myelitis is part of a spectrum of neuroimmunologic diseases of the central nervous system. Other disorders in this spectrum include acute disseminated encephalomyelitis (ADEM), optic neuritis and neuromyelitis Optica (Devic's disease). The TMA was established in 1994 as an organization dedicated to advocacy for those who have these rare neuroimmunologic diseases. The TMA facilitates support and networking opportunities among families, supports and conducts workshops involving both professionals and patients for the exchange of information regarding research and treatment strategies. The association also offers appropriate referrals; engages in patient and professional education; and serves as a clearinghouse of information on transverse myelitis, offering a variety of reports and brochures. TMA has members in over 80 countries around the world. A member directory is available to find members to offer information and support to patients.
