Abstract

Multiple sclerosis (MS) is normally considered a chronic inflammatory disease of the central nervous system (CNS), where T-cells breaching the blood brain barrier react against proteins of the axonal myelin sheaths, leading to focal plaques and demyelination in the brain and spinal cord. Many current therapies are immunosuppressive in nature and are designed to target the immune system at an early stage of the disease. But there is no cure and MS may evolve into a neurodegenerative disease, where immunomodulatory treatments appear less effective. Neurodegeneration is influenced by oxidative and endoplasmic reticulum (ER) mediated stress which can be induced independently of immune processes. Since 1970, MS patients have been self-managing their long term symptoms using hyperbaric oxygen and reporting improvement in their symptoms, especially bladder control. In contrast, the majority of clinical trial evidence does not support the views of patients. Therefore does oxygen under pressure affect brain tissue by modulating oxidative or ER stress at the cellular level resulting in CNS tissue repair or deterioration? This chapter reviews our understanding and the role of oxidative and ER stress in the context of employing hyperoxia treatments to treat MS and evaluate its effects on neural cells.
