Patients with cerebral infarction have hallucinations, which can be treated with small doses of antipsychotic drugs in severe cases, and clinically, oral olanzapine can be administered. At the same time, the cause of the cause should be actively analyzed, and the corresponding treatment should be carried out for the cause. Hallucinations in patients with cerebral infarction can be caused by the cerebral infarction itself or may be caused by hyponatremia caused during the treatment of cerebral infarction. Caused by the cerebral infarction itself, mainly seen in patients with lesions in the frontal and temporal lobes, the cerebral infarction should be actively treated if it is caused by the infarction itself. In patients with ultra-early stage, if the symptoms and signs are severe, intravenous thrombolytic therapy can be given if it is suitable for thrombolysis; if it is not suitable for thrombolysis or if the time window for thrombolytic therapy is exceeded, aspirin antiplatelet aggregation should be given as much as possible, and at the same time, neuroprotection as well as treatment to improve blood circulation should be given. Butalbital can also be given if necessary to improve the signs and symptoms of neurological deficits. Electrolytes should be monitored, and if hyponatremia occurs, it should be corrected promptly, mainly by giving intravenous concentrated salt to prevent coma in case of severe hyponatremia.
