[Current description of multiple sclerosis].
Multiple sclerosis is a multifocal demyelinating disease leading to progressive neurodegeneration caused by an autoimmune response in genetically predisposed individuals. In the last few years, the knowledge and management of this disease has been revolutionized by a series of findings. The present article reviews pathological features of the disease, in which cortical involvement is increasingly implicated, and aspects related to novel pathogenic mechanisms, such as the role of the microbiota in the genesis of multiple sclerosis, as well as recent contributions from the fields of epidemiology and genetics. Also reviewed are the latest diagnostic criteria, which currently allow a much earlier diagnosis, with clear therapeutic implications.
