It is not good for a patient to sleep all the time after suffering from a brain infarction, which means that the patient’s condition is relatively serious and the patient is in a drowsy or coma state, which may be caused by a large brain infarction or a brain infarction in a special area. In this case, it may be caused by a large cerebral infarction or a special site of cerebral infarction. The special site of cerebral infarction is mainly found in the hypothalamus, because the damage to the hypothalamus will affect the patient’s sleep and wakefulness disorder, which can lead to deep sleep or coma in severe cases, so timely treatment is necessary. In addition to active medication for cerebral infarction, improving cerebral blood circulation, patients should pay attention to prevent various complications during sleep or coma, such as upper gastrointestinal bleeding or intrapulmonary infection, urinary tract infection and other comorbidities.
