Brain atrophy in multiple sclerosis: therapeutic, cognitive and clinical impact

ABSTRACT

Multiple sclerosis (MS) was always considered as a white matter inflammatory disease. Today, there is an important body of evidence that supports the hypothesis that gray matter involvement and the neurodegenerative mechanism are at least partially independent from inflammation. Gray matter atrophy develops faster than white matter atrophy, and predominates in the initial stages of the disease. The neurodegenerative mechanism creates permanent damage and correlates with physical and cognitive disability. In this review we describe the current available evidence regarding brain atrophy and its consequence in MS patients.

RESUMEN

La esclerosis múltiple (EM) fue considerada históricamente como una enfermedad inflamatoria de la sustancia blanca. Hoy en día hay mucha evidencia que apoya, además, el compromiso de la sustancia gris y los mecanismos neurodegenerativos, que son al menos parcialmente independientes de la inflamación. La atrofia de la sustancia gris se desarrolla más rápido que la atrofia de la sustancia blanca y predomina en las etapas iniciales de la enfermedad. El mecanismo neurodegenerativo, crea un daño permanente y se correlacionaría con la discapacidad física y cognitiva del paciente. En esta revisión, se describe la evidencia disponible actual con respecto a la atrofia cerebral y su consecuencia en los pacientes con EM.
