Bilateral basal ganglia cavernous cerebral infarction is the appearance of some small infarct foci in the basal ganglia area on both sides. Bilateral basal ganglia cavernous cerebral infarction indicates that the infarct foci are localized in the basal ganglia on both sides, and the area is small, with a diameter of 3~15 mm, which is mostly seen in middle-aged and old people, especially in patients with hypertension and diabetes mellitus. The etiology is mainly due to the infarction of the arteries of the deep penetrating branches of the brain. It can lead to hemiparesis, hemiplegia, ataxia, dysarthria and other symptoms. Recurrent lacunar cerebral infarction can lead to cognitive dysfunction. If the above symptoms occur, the patient should go to the hospital in time for active treatment to improve the patient’s prognosis.
