Deep ischemic foci in the white matter of the brain are mainly considered to be caused by atherosclerosis or occlusion of small arteries in the deep perforating branches of the brain, and the causes include degenerative lesions, lacunar cerebral infarction, and subcortical arteriosclerotic encephalopathy.
1. Degenerative lesions: as people age, atherosclerosis of small blood vessels can occur, and ischemia and hypoxia of brain tissues are manifested as deep ischemic foci in the white matter of the brain, with most of the patients having no obvious symptoms.
2. Cavernous cerebral infarction: this disease is mainly on the basis of long-term hypertension, deep penetrating limb arteries undergo vitellogenic changes, and eventually the blood vessels are occluded, the brain tissue is ischemic and hypoxic, forming deep ischemic foci in the cerebral white matter.
3. Subcortical arteriosclerotic encephalopathy: the causes include diabetes mellitus, hypertension, hyperhomocysteinemia and so on. Memory loss and cognitive impairment may occur at the onset of the disease.
Deep cerebral ischemic foci are recommended to consult the neurology department of the hospital, under the guidance of professional doctors to clarify the cause of the disease and the severity of the disease and give targeted treatment.
