Developmental language transtorno com impairment of mainly pragmatic language is characterised by persistent and marked difficulties com the understanding and uso of language in social contexts, for example making inferences, understanding verbal humour, and resolving ambiguous meaning. These difficulties arise during the developmental period, typically during early childhood, and cause significant limitations in the individual’s ability to communicate. Pragmatic language abilities are markedly below the expected level given the individual’s age and level of intellectual functioning, but the other components of receptive and expressive language are relatively intact. This qualifier should not be used if the pragmatic language impairment is better explained by Transtorno do espectro autista or by impairments in other components of receptive or expressive language.
