The chance of recovering speech if the cerebral infarction will not be able to speak depends on the size of the infarcted foci and the location of the infarction. If the area of cerebral infarction is relatively small and only partially involves the speech center, or involves the non-dominant hemisphere, there is a possibility of recovering speech function by actively carrying out correct speech function training in the later stage, but some patients may have certain sequelae. If the area of cerebral infarction is larger and the condition is more serious, involving the language center of the dominant hemisphere, leading to the emergence of language dysfunction, the chances of recovering normal speech are not great. Even if strict language function training is actively carried out at a later stage, it can only improve the situation of not being able to speak, and it is difficult to restore normal language function. Once cerebral infarction occurs, it is recommended to go to regular hospitals as soon as possible for diagnosis and treatment, and to formulate scientific and reasonable treatment plan in time to control the condition as soon as possible and improve the symptoms of patients after cerebral infarction, so as to avoid leaving serious sequelae. If the patient cannot speak after cerebral infarction, family members should actively cooperate with the patient to carry out language rehabilitation exercise under the guidance of professional doctors to promote the improvement of language function.
