Cavitary infarction may fall down when it occurs. Cavitary infarction is known as lacunar cerebral infarction, and patients may have mild headache, dizziness, numbness and weakness of limbs, crooked mouth, etc. Some of the patients who have weakness of limbs may fall down, and some of the patients may not have any obvious symptom, and only be accidentally found when they do the checkup. Cavernous cerebral infarction is a kind of cerebral infarction that occurs in the terminal artery of the deep penetrating branch of the brain, and the scope of infarction is usually small, and some of the patients may not have any obvious clinical symptoms, and they are only found by accident when they are being examined, so they usually do not fall down. Some patients with lacunar cerebral infarction may present with mild hemiparesis, hemiplegia, oblique mouth, salivation, dysphonia, dysphagia and other symptoms at the onset of the disease, and patients with mild hemiparesis may present with a fall. If cavernous cerebral infarction is diagnosed, more serious symptoms may occur due to the possibility of recurrent cerebral infarction, so please consult a doctor in time and follow the doctor’s instructions for treatment.
