CNS Demyelinating Diseases
Demyelinating CNS Diseases — Expert Level Reference
How it begins
From oligodendrocyte and the molecular architecture of the node of Ranvier to plaque, budding and silent progression. Multiple sclerosis, neuromyelitis optica, MOGAD, acute disseminated encephalomyelitis and metabolic-toxic and infectious demyelination, with their biology, immunopathology, detailed diagnostic criteria, neuroimaging, cerebrospinal fluid, biomarkers and the modern therapeutic arsenal...
