Bilateral frontal subcortical ischemia is an ischemic cerebrovascular disease. This condition is usually associated with hypertension, diabetes mellitus and hyperlipidemia. It is associated with focal brain tissue necrosis caused by atherosclerosis and occlusion of small blood vessels. Ischemic diseases of the brain are disorders in which the blood supply to brain tissue is insufficient for a variety of reasons, leading to corresponding neurological symptoms. They are relatively common in clinical practice, and generally small ischemic lesions do not easily cause symptoms. The frontal lobe takes on fewer functions compared to other brain functions. The main expression is in emotional personality and mental state, so an ischemic lesion in this area may be asymptomatic if it is small in extent. If extensive, personality and mood changes may occur in severe cases. When a patient develops ischemic cerebrovascular disease, he or she should go to the hospital in time for treatment under the guidance of a doctor.
