The report of MRI
of white matter
hyperintensity and microvascular ischemic means there is decreased blood supply to to a part of white matter of brain... MS means multiple sclerosis
... minor ischemia
will not affect any body function also it may be restored by a sort duration.. it it is a large area then you need to get treated for it...
Hope I have answered your question..
