What is white matter ischemia?

Cerebral white matter ischemia, mostly found in brain tissue ischemia-hypoxia disease caused by acquired demyelinating disease of central nervous system. Acquired demyelinating disease of central nervous system is divided into demyelinating disease secondary to other diseases and primary immune mediated inflammatory demyelinating disease. The former includes ischemic and hypoxic diseases delayed leukoencephalopathy after carbon monoxide poisoning (such as subacute combined degeneration), central pontine myelinolysis, diseases caused by viral infection, etc. The latter is a clinically normal demyelination disease of the central nervous system, mainly including idiopathic inflammatory demyelination disease of the central nervous system, which is a group of diseases with demyelination and inflammation of the central nervous system in etiology and autoimmunity, including multiple sclerosis, optic neuromylitis, concentric sclerosis, disseminated encephalomyelitis, etc.
