Recent data suggest that the mechanisms of demyelination and tissue damage in multiple sclerosis (MS) are heterogenous.
In this review, evidence is discussed, which show that in a subset of multiple sclerosis patients the central nervous system (CNS) lesions show profound similarities to tissue alterations found in acute white matter stroke, thus suggesting that a hypoxia-like metabolic injury is a pathogenetic component in a subset of inflammatory brain lesions.
Both, vascular pathology as well as metabolic
disturbances induced by toxins of activated macrophages and microglia may
be responsible for such lesions in multiple sclerosis.
