Definition: 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 beh ...[+++]avioural disorders.

Definition: A type of pervasive developmental disorder that differs from childhood autism either in age of onset or in failing to fulfil all three sets of diagnostic criteria. This subcategory should be used when there is abnormal and impaired development that is present only after age three years, and a lack of sufficient demonstrable abnormalities in one or two of the three areas of psychopathology required for the diagnosis of autism (namely, reciprocal social interactions, communication, and restricted, stereotyped, repetitive behaviour) in spite of characteristic abnormalities in the other area(s). Atypical autism arises most often in profoundly retarded individua ...[+++]ls and in individuals with a severe specific developmental disorder of receptive language. | Atypical childhood psychosis Mental retardation with autistic features

Definition: 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 tempo ...[+++]ral 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.

We have data that indicate that there are delays with respect to language development, cases of FAS/FAE, delays with respect to behaviour, development, visual problems, the brain, and autism.

It may be a matter of delays, language problems or developmental delays, or specific physical problems.

The period from birth to three is critical for children’s brain development, physical and cognitive development, and language acquirement.

This period is critical for cognitive, sensory and motor development, affective and personal development and language acquisition, and also provides the basis for lifelong learning.
