Expressive language disorder is one of the "specific developmental disorders of speech and language" recognized by the tenth edition of the International Classification of Diseases (ICD-10). As of the eleventh edition (ICD-11, current 1 January 2022), it is considered to be covered by the various categories of developmental language disorder .
Nonetheless, because their comprehension of spoken language is mostly preserved, and because their speech is usually good enough to get their point across, the agrammatic nature of their speech suggests that the disorder chiefly involves the expressive mechanisms of language that turn thoughts into well-formed sentences.
Although disorders such as expressive aphasia, conduction aphasia, and dysarthria involve similar symptoms as apraxia of speech, the disorders must be distinguished in order to correctly treat the patients. [citation needed] While AOS involves the motor planning or processing stage of speech, aphasic disorders can involve other language processes.
Language-processing research informs theories of language. The primary theoretical question is whether linguistic structures follow from the brain structures or vice versa. Externalist models, such as Ferdinand de Saussure's structuralism, argue that language as a social phenomenon is external to the brain. The individual receives the ...
Language disorders can also be categorized as developmental or acquired. A developmental language disorder is present at birth while an acquired language disorder occurs at some point after birth. Acquired language disorders can often be attributed to injuries within the brain due to occurrences such as stroke or Traumatic brain injury.
The individual knows what they want to say, but their brain has difficulty coordinating the muscle movements necessary to say those words. [2] The exact cause of this disorder is usually unknown. [1] Many observations suggest a genetic cause of DVD, as many with the disorder have a family history of communication disorders.
Neuroscience of multilingualism is the study of multilingualism within the field of neurology.These studies include the representation of different language systems in the brain, the effects of multilingualism on the brain's structural plasticity, aphasia in multilingual individuals, and bimodal bilinguals (people who can speak at least one sign language and at least one oral language).
Research questions include what course language information follows through the brain as it is processed, [19] whether or not particular areas specialize in processing particular sorts of information, [20] how different brain regions interact with one another in language processing, [21] and how the locations of brain activation differ when a ...
