Patients with small ischemic foci in the frontal lobes bilaterally may or may not experience symptoms such as dizziness, impaired limb movement, impaired limb sensation, and emotional and mental changes. The frontal lobe has a complex function; the body’s motor and sensory centers are located in the frontal lobe and are able to regulate the flexibility of limb movement. The frontal lobes are also involved in the body’s mental activity. Small ischemic foci in the frontal lobes bilaterally often indicate cerebral infarction in the frontal lobes. If infarction occurs, there will be dizziness, limb movement disorder, limb sensation disorder, and mental and emotional disorders, for example, some patients will become more indifferent, and may have symptoms such as depression. Patients may also be asymptomatic if the ischemic foci are very small or do not affect functional areas. The main factor of bilateral frontal lobe ischemic foci is cerebral atherosclerosis, and if the patient is accompanied by hypertension, hyperglycemia, hyperlipidemia, smoking, etc., the risk factors should be corrected in time, and the probability of cerebrovascular disease can be reduced. Therefore, small ischemic foci in bilateral frontal lobe should be vigilant, timely consultation and regular medication.
