What Is the Difference Between Language and Speech Disorders?

Speech and language disorders. In medical clinics, the former refers to pathological phenomena that affect the basic verbal communication process through audiovisual channels, and the latter refers to pathological phenomena that affect higher-level processes such as the meaning of sentences or understanding of the meaning of others' speech.

The most common cause of "slow speech development" is hearing loss, which is mostly caused by recurrent ear infections or "wet ears." Speech retardation may be a physical abnormality, such as "cerebral palsy," or it may be genetic. Children may have difficulty controlling the different body parts required for speech. If a child rarely talks or associates with his parents, he will speak later than other children. Children from bilingual families, left-handed, or both hands may also speak later.

In medical clinics, pathological phenomena that affect the basic verbal communication process through audiovisual channels are speech disorders; while pathological phenomena that affect higher-level processes such as sentence making or understanding of other people's speech meanings are language barriers. Speech disorders refer to organic lesions of sight, hearing, pronunciation, writing organs, and developmental speech disorders such as stuttering and inability to produce certain consonants, and so on. Language disorders are common in the developmental period, such as children's delay in learning, and in the period of general language maturity, they still fail to reach the normal speech level. They are also found in some mental disorders. For example, speech and speech are obstructed when aphasia is caused by brain damage. Language ability is an important part of intellectual performance, so language disorders are seen in situations such as mental retardation or mental retardation, delirium, dementia, etc. At this time, the diagnosis of language disorders is not given separately.

Speech and language disorders have always been an important research topic in neurology. In 1836, M. Dax first noticed that the left hemisphere plays a particularly important role in speech. In 1861, P. Broca proposed that the motor speech was "located" in the back of the third frontal gyrus in the left hemisphere from the autopsy case data, and then C. Wernicke put the left third of the upper temporal gyrus with the speech sound The feelings. Their discovery at that time prompted a wave of research into the anatomical location of the various speech centers in the brain. However, because speech is a complex cognitive activity, it did not have reliable physiology, anatomical research techniques, and a lack of mature psychological concepts of speech behavior. Therefore, the study of anatomical positioning is essentially just a general speech phenomenon. Directly linked to a local brain tissue, the results cannot explain the complex multimodal clinical phenomenon. At the same time, British neurologist JH Jackson proposed that aphasia should be regarded as a dysregulation of the brain's behavioral structure at the highest level. He believes that it should be explored from the perspective of genetics, that is, the function of the structure, which has led to future research. profound impact. From the middle of the 19th century to the present, the research on speech and language barriers has not only gone from a static study of the anatomical location of the speech center to a deep study of functional dynamicsthe neurodynamics of speech. Since the 1960s, the emergence of a new branch of science, neurolinguistics, is a sign of the in-depth development of research on speech and language disorders. It uses linguistic, psychological, and neurological theories and methods to carry out research on the speech mechanism of the brain. .
