Patients with secondary cerebral infarction can present with different clinical symptoms, depending mainly on the size of the infarct focus and the site of infarction. In the case of large hemispheric infarcts, patients can present with hemiplegia or unilateral limb motor weakness and sensory numbness. Partial and quadrant blindness may also occur. In the case of left-sided lesions, patients may have aphasia and dysarthria, including motor, sensory, and mixed aphasia. If the patient has an infarction of the basilar system, he or she may experience dizziness, nausea, vomiting, dysarthria, dysphagia, choking and coughing, balance and ataxia in some patients, and in severe cases, disorders of consciousness, including drowsiness, lethargy and coma. Patients may also experience confusion and delirium, and may have cerebral edema and increased intracranial pressure. In severe cases of increased intracranial pressure, it can cause brain herniation and lead to the patient’s death.
