Cavernous infarction means lacunar cerebral infarction. Mild lacunar cerebral infarction may cause symptoms such as dizziness, increased salivation, blackness before the eyes, slurred speech, limb weakness, and numbness. Cavernous cerebral infarction usually refers to ischemic and hypoxic changes in the innervated area due to blockage and narrowing of the blood vessels that penetrate the tiny arteries in the brain. Patients with mild lacunar cerebral infarction may suffer from cerebral ischemia, central facial paralysis, mild hemiparesis of limbs, and many other manifestations, such as dizziness, blackness in front of the eyes, increased drooling, slurred speech, inflexibility in turning the tongue, and weakness and numbness of the limbs. Early symptoms of lacunar cerebral infarction are relatively mild, but still need to be closely watched, because it is easy to progress to large cerebral infarction or multiple recurrences, once this change is found, it is necessary to go to the hospital for standardized diagnosis and treatment in a timely manner. Patients with lacunar cerebral infarction should go to the hospital in time, and after clarifying the cause of the disease, they should be handled and treated accordingly under the guidance of doctors.
