Background:
Multiple sclerosis is a chronic inflammatory demyelinating disease of the central nervous system. With a prevalence of 0.1-0.15% in Germany multiple sclerosis is the most common cause of severe disability in young adults.
Pathogenesis:
Epidemiological and family studies demonstrate the role of environmental and genetic factors in the pathogenesis of multiple sclerosis. Based on those observations and findings in experimental animal models, it is believed that multiple sclerosis is caused by an autoimmune process. However, target antigens and mechanisms leading to tissue destruction are largely unknown.
Therapy:
Since the efficacy of current immunomodulatory and immunosuppressive therapies (beta-interferons, glatiramer acetate, mitoxantrone) is limited, it is necessary to develop new strategies for the treatment of multiple sclerosis. To reach this goal, a much better understanding of disease pathogenesis is necessary which takes into account the clinical, paraclincial and histopathological heterogeneity of the disease.
Conclusion:
Only further intensive research activity on basic mechanisms of disease pathogenesis and a consequent development of resulting therapeutic strategies--from animal models to phase III studies--will result in significant improvement of the long-term course of multiple sclerosis.
