Chapter V
Specific developmental disorders of speech and language - F80
Disorders in which normal patterns of language acquisition are disturbed from the early stages of development. The conditions are not directly attributable to neurological or speech mechanism abnormalities, sensory impairments, mental retardation, or environmental factors. Specific developmental disorders of speech and language are often followed by associated problems, such as difficulties in reading and spelling, abnormalities in interpersonal relationships, and emotional and behavioural disorders.

Specific speech articulation disorder
A specific developmental disorder in which the child's use of speech sounds is below the appropriate level for its mental age, but in which there is a normal level of language skills.
Developmental:
phonological disorder
speech articulation disorder
Dyslalia
Functional speech articulation disorder
Lalling
Excludes:
- speech articulation impairment (due to):
- aphasia NOS ( R47.0 )
- apraxia ( R48.2 )
- hearing loss ( H90-H91 )
- mental retardation ( F70-F79 )
- with language developmental disorder:
- expressive ( F80.1 )
- receptive ( F80.2 )
|
| F80.1 |
Expressive language disorder
A specific developmental disorder in which the child's ability to use expressive spoken language is markedly below the appropriate level for its mental age, but in which language comprehension is within normal limits. There may or may not be abnormalities in articulation.
Developmental dysphasia or aphasia, expressive type
Excludes:
- acquired aphasia with epilepsy [Landau-Kleffner] ( F80.3 )
developmental dysphasia or aphasia, receptive type ( F80.2 )
dysphasia and aphasia NOS ( R47.0 )
elective mutism ( F94.0 )
mental retardation ( F70-F79 )
pervasive developmental disorders ( F84.- )
|
| F80.2 |
Receptive language disorder
A specific developmental disorder in which the child's understanding of language is below the appropriate level for its mental age. In virtually all cases expressive language will also be markedly affected and abnormalities in word-sound production are common.
Congenital auditory imperception
Developmental:
dysphasia or aphasia, receptive type
Wernicke's aphasia
Word deafness
Excludes:
- acquired aphasia with epilepsy [Landau-Kleffner] ( F80.3 )
autism ( F84.0-F84.1 )
dysphasia and aphasia:
- NOS ( R47.0 )
- expressive type ( F80.1 )
elective mutism ( F94.0 )
language delay due to deafness ( H90-H91 )
mental retardation ( F70-F79 )
|
| F80.3 |
Acquired aphasia with epilepsy [Landau-Kleffner]
A disorder in which the child, having previously made normal progress in language development, loses both receptive and expressive language skills but retains general intelligence; the onset of the disorder is accompanied by paroxysmal abnormalities on the EEG, and in the majority of cases also by epileptic seizures. Usually the onset is between the ages of three and seven years, with skills being lost over days or weeks. The temporal association between the onset of seizures and loss of language is variable, with one preceding the other (either way round) by a few months to two years. An inflammatory encephalitic process has been suggested as a possible cause of this disorder. About two-thirds of patients are left with a more or less severe receptive language deficit.
Excludes:
- aphasia (due to):
- NOS ( R47.0 )
- autism ( F84.0-F84.1 )
- disintegrative disorders of childhood ( F84.2-F84.3 )
