There are various manifestations of cerebral infarction exacerbation, for example, patients may suddenly experience increased sensory and motor deficits in the affected limb, increased speech dysfunction, increased hemianopia, and so on. In the case of infarction of the vertebrobasilar system, patients may experience increased symptoms and signs such as dizziness, nausea, vomiting, balance disorders, ataxia or dysphagia, choking and coughing. If the patient is a large cerebral infarct with a history of impaired consciousness, he or she may also experience an increased degree of consciousness, such as originally being drowsy, which can become coma, mainly due to cerebral edema, or due to progressive infarction with gradual expansion of the infarct focus. If the patient is due to cerebral edema, it usually starts to appear on the second day of onset, peaks on 4-5 days, and generally subsides on the seventh day. The exacerbation period usually begins on day 4-5 of onset and is mainly treated with dehydration and lowering of cranial pressure. If the patient has a progressive stroke, the primary cause of the cerebral infarction is treated primarily. In addition, symptom exacerbation may also be due to complications and is often exacerbated if the patient has a combination of electrolyte disturbances, pulmonary infections, urinary tract infections, and upper gastrointestinal tract ulcers.
