Multiple sclerosis (MS) is a chronic, immune-mediated disease of the central nervous system (CNS). It is a complex, multi-factorial disease that includes inflammatory and neurodegenerative processes manifesting both focally in the form of lesions and diffusely in otherwise normal-appearing brain tissue. Recent data shows that ACTH can have beneficial effects on specific neurodegenerative diseases and it may have superior neuroprotective effects. Adding a regimen of ACTH to standard Avonex treatment may provide neuroprotection and promote remyelination.
