[Therapy of Language Disorders in Childhood: A Guideline is long overdue].

In speech and language therapy of developmental language disorders, it is still largely unclear how evidence from individual therapeutic expertise integrates into clinical-practical procedure. Therefore, development of a therapy guideline addressing language disorders in childhood, especially for kindergarten- and preschool children, is long overdue for two reasons and poses a particular challenge: (1) Language disorders that are not associated with a comorbidity are given varying terms; (2) all language disorders are an interface between medical, psychological, educational, linguistic and language therapeutic disciplines. The German Society for Phoniatrics and Pedaudiology has registered now an evidence-based (S3) national "Interdisciplinary Guideline for the Therapy of Language Disorders in Childhood" (in the Association of the Scientific Medical Societies AWMF; register no. 049-015). That should close the gap between language-therapeutic practice and research, and thus to provide the best evidence-based therapy recommendation respectively therapy decision in a specific therapy case.
