ABSTRACT

In the study of developmental language disorders, term referring to speech production disorders in children, such as syllable reduction, mispronunciation, or substitution of individual sounds (partial dyslalia) or of many sounds (multiple dyslalia) up to the point of unintelligibility (universal dyslalia). A particular kind of dyslalia is known as paralalia. Dyslalia is distinguished from dysglossia, a condition which results from structural defects, and from dysarthria, a condition due to acquired neural impairments. The term ‘dyslalia’ is not currently used in North America. ( also articulation disorder, phonological disorder)

Term covering a number of reading disorders with different causes. As with language disorder, acquired dyslexia, often referred to as alexia, and developmental dyslexia are distinguished.
