Neurophysiological Changes in Patients with Discirculatory Encephalopathy Associated with Ischemic Optic Neuropathy

Background. The most common chronic cerebrovascular pathology is dyscirculatory encephalopathy, in which a decrease in blood supply due to damage to brachiocephalic vessels leads to damage to brain substances and analyzers, including visual, with the possible development of severe damage in the form...
