The chances of recovering from a stroke without speech depend on the severity of the lesion and whether the patient was treated properly in the early stages and whether he or she underwent active rehabilitation in the later stages. If the patient is treated with intravenous thrombolysis within 4.5 hours of onset, most of the patients’ symptoms can be significantly improved if the blood vessel is reopened, and the chances of recovery of speech dysfunction are higher at this time. If the patient exceeds the 4.5-hour thrombolysis time window, he can only be given conventional treatment for cerebral infarction at this time. At this time, the brain tissues in the center of the infarct are already necrotic and can only rely on the surrounding ischemic, but the loss of function is likely to be salvaged, to compensate for its function, and the goal of treatment is also mainly to save the function of these brain tissues. Then in about 3-6 months, after a certain period of rehabilitation, the chances of patients being able to speak again are about 30%-50, and some patients will remain aphasic for a long time and cannot speak.
