Abstract
This article will present a neurological childhood speech sound disorder kown as Childhood apraxia of speech (CAS) based on the researches of some specific characteristics. Various authors agree that the childhood apraxia of speech is a disorders in which the precision and consistency of movements underlying speech are impaired in the absence of neuromuscular deficits (e.g., abnormal refl exes, abnormal tone). CAS may occur as a result of known neurological impairment, as a consequence of neurobehavioral disorders of known or unknown origin, or it can be an idiopathic neurogenic speech sound disorder. According to these authors, the main problem is planning and/or programming spatiotemporal parameters of movement sequences which can result with errors in speech and prosody. One of the main problems regarding this disorder in research and clinical practice is recognizing the right time for distinguishig this disorder from other speech language disorders. This article will elaborate some speech and language disorders such as articulation and phonological disorders, specific language impairment, dysarthria and oral apraxia.
