Multiple sclerosis (MS) is an immune-mediated disorder of the central nervous system caused by the systemic damage to the insulating covers of nerve cells. This disrupts the communication ability of the nervous system, resulting in signs and symptoms that are symptomatic of mental, physical and psychiatric issues. The underlying mechanism of the disease is generally attributed to the failure of the myelin-producing cells or destruction by the immune system, brought about by genetics or environmental factors. Multiple sclerosis is diagnosed on the basis of existing signs and symptoms, through medical imaging and lab testing. There is no cure of multiple sclerosis but several therapies allow a quality of care to patients. Such therapies strive to prevent new attacks, prevent disability and recuperate from an attack. This book aims to shed light on some of the unexplored aspects of multiple sclerosis and the recent researches in this disease. It strives to provide a fair idea about this condition and to help develop a better understanding of the latest advances in its management and treatment. The extensive content of this book provides the readers with a thorough understanding of the subject.
