Rare neuroimmunologic disorders are complex with potentially lifelong complications that affect many aspects of an individual’s life. These rare autoimmune disorders of the central nervous system include Neuromyelitis Optica Spectrum Disorder (NMOSD), Transverse Myelitis (TM), Optic Neuritis (ON), Acute Disseminated Encephalomyelitis (ADEM), and Anti-NMDA Receptor Encephalitis (NMDAR-Ab). Management of these disorders will require the expertise of multiple disciplines working together to meet the dynamic needs of the person and the family. Rapid advances in the treatment of rare neuroimmunologic disorders require that health professionals have the basic knowledge and skills necessary to provide optimal care. The Consortium of Multiple Sclerosis Centers supports a voluntary certification process that reflects the knowledge of multiple disciplines in the specialized care of rare neuroimmunologic disorders.
Certification is intended to promote quality and consistent care to those living with rare neuroimmunologic disorders by:
- Formally recognizing knowledge across the multiple disciplines that are necessary for rare neuroimmunologic disorders care delivery.
- Establishing a level of knowledge required for Certification in Rare Neuroimmunologic Disorders.
- Providing encouragement for continued personal and professional growth in the care of individuals with rare neuroimmunologic disorders.
- Providing a standard of knowledge requisite for certification, thereby assisting the employer, public, and members of the health professions in the assessment of healthcare professionals involved in the care of people with rare neuroimmunologic disorders.
All licensed health professionals, with a recommended one year of experience in providing services for or interacting with individuals with rare neuroimmunologic disorders, will be eligible to take a certification examination in rare neuroimmunologic disorders. Those who successfully pass the Certification Examination in Rare Neuroimmunologic Disorders are eligible to use the registered designation CRND after their names and will receive certificates from CMSC.
