Neuroepidemiology of transverse myelitis and its etiologies in Latin America: A systematic review and meta-analysis.

Background And Objectives: Transverse myelitis (TM) is a rare neuro-inflammatory condition of the spinal cord that can cause chronic and debilitating symptoms reducing quality of life. TM is understudied in developing regions worldwide, particularly in Latin America and the Caribbean (LAC), where the prevalence of TM is unknown. Etiologies of TM are variable, but certain infectious, autoimmune or nutritional abnormalities may be more common in LAC with differing estimated prevalences of these etiologies.
