Cerebral leukoaraiosis is a diagnostic imaging condition characterized by diffuse cerebral ischemia on cranial CT or MRI films, resulting in demyelinating changes in the white matter of the brain. Demyelinating changes are seen mainly in the white matter areas of the brain in the form of punctate, paraventricular, anterior and posterior horn flakes. The onset of the disease is more common in the elderly, such as those with a history of hypertension or diabetes mellitus, who have small vessel disease in the brain. There are also cases of middle-aged onset, which may be related to genetic factors. Cerebral leukoaraiosis is more common in neurology and is called demyelination of the white matter of the brain. The main symptom is a decrease in brain function, such as chronic progressive memory loss, slow reaction, dizziness, drowsiness, and other dementia, and some patients may have a combination of phantom vision, hallucinations, mania, and uncontrollable behavioral activities and other psychiatric symptoms.
