Seven days of cerebral infarction is generally not over the danger period, the danger period of cerebral infarction is generally within 14 days of the onset of the disease, during which the patient is prone to cerebral edema, and there is a risk of cerebral herniation. After cerebral infarction, patients will have a period of cerebral edema for about 14 days, in which cerebral edema reaches its peak in about 5 days after the onset of the disease, and at this time, cerebral hernia is very likely to occur, therefore, especially for patients with large cerebral infarction, while actively treating infarcted area to save the ischemic brain tissues, they should be actively carried out dehydration treatment, to prevent aggravation of cerebral edema from further damaging brain tissues and cerebral nerves, resulting in serious after-effects or complications. Usually, two weeks after the onset of cerebral infarction, the patient can enter the recovery period. For patients with stabilized cerebral infarction, rehabilitation therapy and training should be started as soon as possible to restore the patient’s ability to take care of himself in daily life as much as possible.
