What Is a Dysarthria?

Dysarthria refers to speech disorders caused by neuropathy, paralysis of muscles associated with speech, weakened contractility, or uncoordinated movement. Stresses changes in breathing, resonance, pronunciation, and rhythm, and pathological changes from the brain to the muscles themselves can cause speech symptoms.

Dysarthria

Dysphonia Introduction

Causes of dysarthria

Dysarthria

This is for children born with hypoxia or brain damage caused by dystocia and other factors, which cause the part of the brain responsible for language to be stunted, resulting in language disorders in children, mainly manifested in the delay in the occurrence and development of spoken language, or has been inactive Sexual language can only passively answer questions with simple words, and it is often accompanied by intellectual defects. This type of language disorder is difficult to treat.

Dysphonia central nervous system disease

According to international case studies, children under 2 years of age suffer from central nervous system diseases, such as encephalitis, febrile convulsions, and viral infections, which cause brain tissue damage, which causes children to lose their original language ability before the illness. This type of language disorder, called aphasia, is also one of the articulation disorders. Generally after the treatment of the primary disease and the application of neuropharmaceuticals, the symptoms of speech impairment can be reduced or returned to normal. Central nervous system disease is not only common in early childhood, it is also not uncommon in adolescence. Hearing disorders are also a type of disease, which also causes speech disorders. Human language development must rely on normal hearing. Application of certain drugs in infants and young children, such as gentamicin and diuretics, can cause pediatric inner ear poisoning and hearing loss, which can lead to pediatric language disorders. Noise greater than human hearing interferes with our hearing system for a long time in our daily life. It can also cause hearing impairment, and speech disorders caused by ototoxic drugs such as children's hearing disorders are best treated by intervention before the age of 3, otherwise it is difficult to cure .

Dysarthria

Such as malformation of the vocal organs. Patients with laryngeal deformities are very rare, mainly due to oral cleft palate, cleft lip and deformities of the tongue, or accidental deformities caused by traffic accidents, which lead to speech disorders. Its characteristic is that it can be pronounced, but the language is very unclear. At present, most children's treatments require correction of the deformity before the age of 3, and then language training. Most children can restore clear language by themselves. However, accidents that occur in adolescents, middle-aged and elderly people, and various types of accidents require psychological intervention and long-term treatment.

Finally, it was caused by disasters such as car accidents and major blows. Such accidents are generally reversible, but there is no shortage of incurable. In recent years , obstacles to seduce (articulation) caused by natural disasters have been increasing day by day, such as the 2008 heavy snow disaster, the Wenchuan earthquake in 2009, and the Qinghai Yushu earthquake in 2010. Or because of the shock, the psychology can't bear the sudden aphasia; or because of a long-term unwillingness to speak, causing dysarthria.

Classification of dysarthria

Spastic dysphonia (central dyskinesia, generally manifested as laborious speech, prolonged sounds, unnatural interruptions, sharp changes in volume and tone, rough sounds, strenuous sounds, distortion of vowels and consonants, and excessive nasal sounds)

Delayed articulation disorder (peripheral articulation disorder, manifested as inappropriate pauses, breath sounds, wrong consonants, and weakened nasal sounds)

Dysphonic dysphonia (cerebellar system disorders, mainly manifested by less distortion of vowels and consonants, the main rhythm is mainly aberrations, sound level, strength, rigidity, tremor, initial pronunciation difficulties, loud sounds, abnormal stress and intonation, Intermittent pronunciation)

Excessive movement articulation disorder (extrapyramidal disorder, involuntary movement of the articulation organs destroys purposeful movements and causes distortion of vowels and consonants, loss of stress, inappropriate pauses, strenuous sounds, sharp and weak pronunciation (Undulations, excessive nasal sounds)

Excessive articulation disorders (extrapyramidal disorders, due to limited range and speed of movement, pronounced as a single volume, a single tone, reduced stress, breathing or aphasia)

mixed dysarthria (multiple disorders of the motor system, which are manifested as a mixture of the above symptoms, multiple or single indeterminate). Its prevalence is widespread.

Dysarthria

Dysphonia due to abnormalities in the morphology of the articulation organs. 65% are mostly congenital, such as cerebral hypoxia and brain injury. When children are born, hypoxia or brain damage due to dystocia and other factors causes the part of the brain responsible for language to be stunted or abnormal, resulting in language disorders in children. It is mainly manifested in the delay in the occurrence and development of spoken language, or has no active language, and can only use simple words to answer questions. At the same time, it is often accompanied by intellectual defects. Such language disorders are difficult to treat. Other disorders occur from trauma or psychological damage to the morphology and muscle function of the articulation organ.

Functional dysphonia is erratic and confused, but the cause is not found, that is, the morphological organ has no morphological abnormalities and motor function is normal for only a moment. It may be related to auditory acceptance of speech, discrimination, cognitive factors, motor factors to obtain articulation skills, and certain factors of language development. Most of them can be completely cured through articulation training. Mainly occurs in young children.
