Symptoms of recurrence of cerebral infarction mainly include dizziness, nausea, vomiting, accompanied by numbness and weakness of limbs, loss of sensation, unsteady walking, double vision, difficulty in swallowing and speech disorders. Cerebral infarction is easy to recur if preventive measures are not taken after the infarction. If cerebral infarction recurs, nausea, vomiting, dizziness or vertigo and other symptoms will appear, and there will be sudden numbness and weakness of limbs, sensory loss, limitation of limb movement, etc., and when it is serious, it can’t move at all, resulting in hemiplegia in bed. If the speech center is involved, there will be speech disorders, such as slurred speech and complete aphasia. In addition, the patient will also have ataxia, resulting in unsteady walking, double vision when seeing things, swallowing dysfunction and so on. If the above symptoms appear after the cerebral infarction has improved, it is recommended to go to regular hospitals for review and treatment as soon as possible to avoid recurrence of cerebral infarction.
