The diagnoses are made more general in order to capture the various aspects of communications disorders in a way that emphasizes their childhood onset and differentiate these communications disorders from those associated with other disorders (e.g. autism spectrum disorders). Language disorder – the important characteristics of a language disorder are difficulties in learning and using language, which is caused by problems with vocabulary, with grammar, and with putting sentences together in a proper manner. Problems can both be receptive (understanding language) and expressive (producing language). Speech sound disorder – previously called phonological disorder, for those with problems with pronunciation and articulation of their native language. Childhood-Onset Fluency Disorder (Stuttering) - standard fluency and rhythm of speech is interrupted, often causing the repetition of whole words and syllables. May also include the prolongation of words and syllables; pauses within a word; and/or the avoidance of pronouncing difficult words and replacing them with easier words that the individual is better able to pronounce. This disorder causes many communication problems for the individual and may interfere with social communication and performance in work and/or school settings where communication is essential. Social (pragmatic) communication disorder – this diagnosis described difficulties in the social uses of verbal and nonverbal communication in naturalistic contexts, which affects the development of social relationships and dialogue comprehension. The difference between this diagnosis and autism spectrum disorder is that in the latter there is also a restricted or repetitive pattern of behavior.
