Classification of Developmental Language Disorders

Overview

Summary:
The more varied and inconsistent is the terminology that we use to refer to developmental language disorders. Children with unexplained difficulties in language acquisition have been variously referred to as having developmental aphasia, developmental dysphasia, delayed language, developmental language disorder, and, most recently, specific language impairment. The term that is usually preferred in contemporary research is SLI (specific language impairment). Some studies have focused on children with severe comprehension problems, asking how far their difficulties are auditory of linguistic. Others have concentrated on looking for a link between defective speech production and abnormal speech perception. However the identification of speech sounds appears to be a problem for all these groups. At the heart of SLI there is an impairment of auditory perception. In recent years developmental language disorders have ordered between CAPD – central auditory processing disorder. Central auditory deficits (impairment for the acquisition of auditory symbols) coexist with difficulties in children with specific language impairment. In our phoniatric department we use traditional classification sec. prof. Novak (developmental dysphasia and dysarthria and combination of both disorders).

Key words:
developmental language disorders, central auditory processing.
