Axonal damage is a prominent feature of MS responsible for long-term disability and functional deficits in those afflicted with the disease. In this review we outlined biochemical, clinical, neuropathological, and neuroimaging evidence in support of neurodegeneration as a direct consequence of demyelination or as an independently occurring concurrent event. Future studies should continue to address the molecular changes that occur to both axons and myelin in order to determine the specific sequence of events underlying the disease pathogenesis of MS. Novel therapies addressing the neurodegenerative component of the disease may hold clues for halting its progression and promoting functional recovery in those afflicted with MS.
Oligodendrocytes myelinate numerous axonal segments producing the compact myelin sheath that supports the long-term survival of neurons and their axonal segments (A). Axonal damage underlying MS disease progression may occur as a consequence of long-term ...
