Autonomic dysfunctions in multiple sclerosis: Challenges of clinical practice (Review).

Multiple sclerosis, demyelinating, inflammatory, degenerative, and chronic disease, raises many challenges in terms of disease management. The autonomic nervous system is affected by neuroinflammation but also contributes to its maintenance and the evolution of the disease. Multiple sclerosis interfering with parasympathetic or sympathetic modulation may influence the immune response. Less attention is paid to autonomic dysfunctions, although they produce a serious impact on the quality of life. In addition to motor disabilities, patients also have non-motor dysfunctions. Regardless of its clinical forms, patients with multiple sclerosis may have autonomous disturbances such as bladder, sexual, cardiovascular, thermoregulatory, gastrointestinal dysfunction and fatigue. These must be identified based on medical history, clinical symptoms, and specific paraclinical tests. In addition to the multitude of immunomodulatory therapeutic agents that influence the progression of the disease, the therapy of autonomic dysfunctions remains difficult to address. However, their identification and treatment lead to increased quality of patient management and avoid complications of this disease.
