The underlying pathophysiology of multiple sclerosis is presumed to be
autoimmune in nature. Attempts to find an effective treatment for thi
s common disease of the central nervous system have primarily focused
on immune-mediated therapies, both immunosuppressive and immunomodulat
ory. The wide variety of immunological abnormalities detected in multi
ple sclerosis and its animal model, experimental allergic encephalomye
litis, has prompted the testing of a diverse array of drugs to be used
for treatment. Recent successes in the treatment of relapsing-remitti
ng multiple sclerosis with interferon beta and glatiramer acetate have
renewed interest in and raised expectations for the effective control
of this neurological disorder. Improved methodology in clinical trial
s, the development of surrogate markers and the availability of novel
therapies bode well for more rapid advances.
