Regarding the causes of dysarthria, there are basically the following: 1, difficult birth When the child is born, due to difficult birth and other reasons caused by lack of oxygen or brain damage, making the part of the brain responsible for language is poorly developed, resulting in pediatric language disorders, mainly manifested as delayed speech development, or has been no active language, can only passively answer questions with simple words, and more than accompanied by intellectual deficiencies. This type of language disorder is difficult to treat. 2, the central nervous system diseases by international case studies, children within 2 years of central nervous system diseases, such as encephalitis, fever convulsions, viral infections, etc., resulting in brain tissue damage, so that the child lost the original language ability before the disease. This type of language disorder is called aphasia, which is also one of the dysarthria. Generally, after the treatment of the original disease and the application of neurological drugs, the symptoms of language disorder can be reduced or restored to normal. Central nervous system disorders are not only common in early childhood, but also in adolescence. 3, hearing disorders due to hearing disorders caused by language disorders in the clinic is also common. Human language development must rely on normal hearing. The application of certain drugs during infancy, such as gentamicin and diuretics, can cause inner ear toxicity and hearing loss in children, resulting in pediatric speech disorders. Greater than human hearing noise in our daily life long-term interference with our auditory system can also lead to hearing impairment, and hearing disorders in children such as speech disorders due to ototoxic drugs are best treated with intervention before the age of 3 years at least before speech formation (7 years old) (speech therapy after hearing compensation), otherwise it is difficult to cure. 4.Other diseases Such as articulatory organ malformation caused. Patients with laryngeal malformations are rare, mainly oral cleft palate, cleft lip and tongue malformations or malformations caused by accidents such as traffic accidents that lead to speech disorders. It is characterized by the ability to articulate, but the language is very unclear. Most children can regain clear speech on their own by correcting the deformity before the age of 3, followed by language training. However, it is more likely to occur in adolescents or middle-aged or elderly people, and all kinds of accidents require psychological intervention and long-term treatment. 5, car accidents, major blows and other disasters caused by these accidents are generally reversible, but there is no shortage of incurable. In recent years, the number of disorders caused by natural disasters is increasing, such as the snowstorm in 2008, the Wenchuan earthquake in 2009, and the Yushu earthquake in Qinghai in 2010, which led to a higher incidence of the disease. The dysarthria is also called “hysterical aphasia”, which requires psychological treatment. 80% of these patients can be cured.
