###### F80 Specific developmental disorders of speech and language
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

difficulties in reading and spelling, abnormalities
in interpersonal relationships, and emotional and
behavioural disorders.
