Language (1anguage) is formed and developed by human beings in the process of social work and life. It refers to the ability to express one’s thoughts or communicate with others through the use of various means or symbols (gestures, expressions, spoken language, words) and is an acquired, uniquely human and complex mental activity. Speech disorders are various abnormalities in the application or comprehension of spoken language, words, or gestures. The prevalence of symptoms of speech disorders (dysarthria and/or aphasia) due to brain disorders, especially cerebrovascular disease, is quite high. According to data from the 1982 epidemiological survey of cerebrovascular disease in six cities, the annual domestic incidence of cerebrovascular disease was 182 per 100,000 population and the prevalence of attendance was 620 per 100,000 population. Recent data show that cerebrovascular disease has been the leading cause of disease and death in adults. Patients with brain injury can have various manifestations such as speech inability, mispronunciation, stereotyped speech, auditory comprehension disorder, dyslexia, dyscalculia, dyslexia, dyscalculia, naming disorder, etc. The symptoms that occur vary depending on the location of the injury. Speech therapists can, under the guidance of a physician, address the patient’s speech problems —- dysarthria? Which kind of aphasia? etc. to give targeted training for early recovery. The best period of treatment for speech dysfunction can be carried out when the patient is conscious and the vital signs are stable. Try to achieve early detection and early treatment, and the best recovery period is six months.
