Suspected lacunar cerebral infarction in the basal ganglia region on both sides is a type of cerebral infarction, which is a small blood vessel lesion with deep penetrating branches in the cerebral blood vessels, usually within 15 millimeters, with mild symptoms, and most of them are seen in patients with high blood pressure and diabetes mellitus. It is caused by the interruption of blood flow due to the blockage of small blood vessels in the brain, and the brain tissues with corresponding blood supply become dysfunctional due to ischemia, such as neurological dysfunction in the hands and feet of the partial side, unclear speech, and in serious cases, it is life-threatening. Some patients may have no obvious symptoms, which can only be detected by head CT or head MRI. If the infarction occurs in a small blood vessel, it can be seen on imaging, and the diameter of its lesion is usually within 15 mm, which is called lacunar cerebral infarction. The specific etiology is related to hypertension, atherosclerosis, diabetes mellitus, as well as cardiogenic embolus dislodgement, hyperlipidemia, chronic smoking, and alcohol consumption. For the treatment of suspected lacunar cerebral infarction in the basal ganglia region on both sides, it is recommended that the patient consults with a medical professional as soon as possible in the hospital to control the underlying disease and prevent recurrence of cerebral infarction.
