[Developmental Speech and Language Disorders According to ICD-11].

Area of Science:

• Neurodevelopmental Disorders
• Speech and Language Pathology
• Clinical Linguistics

Background:

• The International Classification of Diseases, 10th Revision (ICD-10) faced criticism for its broad classification of speech and language disorders.
• Professionals, including linguists and speech-language therapists, found ICD-10 lacking in specificity for individual language impairments.
• Medical professionals noted the absence of organically caused speech and language problems in the ICD-10 criteria.

Purpose of the Study:

• To present the classification of speech and language disorders according to ICD-11 in comparison to ICD-10.
• To introduce a novel classification approach for speech and language disorders based on ICD-11.
• To foster an interdisciplinary classification system and establish a common terminology for all professions involved.

Main Methods:

• Comparison of ICD-11 classification with ICD-10 criteria for neurodevelopmental disorders.
• Analysis of the differentiation between primary and secondary neurodevelopmental disorders in ICD-11.
• Discussion of alternative classification systems, including DSM-5, CATALISE-2, and Auditory Processing Disorder.

Main Results:

• ICD-11 introduces a more nuanced classification of speech and language disorders within neurodevelopmental disorders.
• The proposed approach supplements ICD-11 by specifying impaired speech or language areas based on thorough assessment.
• The differentiation between primary and secondary neurodevelopmental disorders is a key improvement in ICD-11.

Conclusions:

• The ICD-11 classification offers a more detailed framework for speech and language disorders than ICD-10.
• The proposed supplementary specification aims to enhance diagnostic precision and clinical utility.
• Establishing a common interdisciplinary terminology is expected to improve clinical care and research comparability.
