Crying in patients with cerebral infarction may be a state of delirium caused by the cerebral infarction itself. Patients may experience mood swings, which can lead to crying, or sleep disturbances, or a kind of pseudobulbar palsy caused by the cerebral infarction itself. Patients may also experience choking on water and may cause strong crying and laughing, mostly in large cerebral infarcts, which may be caused by damage to the cortex. Patients may also develop somatic signs and symptoms at the same time, including hemiparesis, hemianopia and hemianesthesia. The main thing is to actively treat the primary disease, intravenous thrombolytic therapy when ultra-early thrombolysis is suitable, and antiplatelet aggregation, neuroprotection and improving blood circulation when thrombolysis is not suitable. If the patient has swallowing dysfunction and it is difficult to recover in the short term, it is suitable to put down the gastric tube and keep the gastric tube for nasal feeding diet, and if necessary, give the drugs to wake up the brain for treatment, such as waking up the brain and compound musk.
