兒童期言語失用症

维基百科,自由的百科全书

兒童期言語失用症,也被称为發展性言語失用症,是指当儿童在發語音、音节和文字時出現困難。此種困難並非肇因於肌肉無力或麻痺,而是大脑在計畫說話所需的身體部位(例如,嘴唇、下巴、舌頭)時,出現困難。儿童知道他们想说什麼,但是他们的大脑在協調說話所需的肌肉动作時,出現問題造成此种疾病的確切原因是未知的部分觀察指出,基因遗传為導致兒童期言語失用症的原因,因为许多患者都具有溝通障礙的家族病史。兒童期言語失用症无法被治愈,但是透過适当且密集的介入,患有此种運動言語障礙的人,可以獲得显着的進步。

特徵

"Childhood apraxia of speech (CAS) is a neurological childhood (pediatric) speech sound disorder in which the precision and consistency of movements underlying speech are impaired in the absence of neuromuscular deficits (e.g., abnormal reflexes, abnormal tone). CAS may occur as a result of known neurological impairment, in association with complex neurobehavioral disorders of known or unknown origin, or as an idiopathic neurogenic speech sound disorder. The core impairment in planning and/or programming spatiotemporal parameters of movement sequences results in errors in speech sound production and prosody." American Speech-Language-Hearing Association (ASHA) Ad Hoc Committee on Apraxia of Speech in Children (2007)[1]

「兒童期言語失用症是種小兒神經性的言語-語音障礙,是指在沒有神經肌肉缺損(例如異常的反射、異常的張力)的前提下,其說話時基本動作的精準度及一致性受到損傷。已知的神經性疾病、已知或未知的複雜神經行為障礙,或是原發性的神經性言語-語音障礙,皆可能導致兒童期言語失用症。其核心損傷主要出現在計畫動作序列之時間與空間向度上,導致在發音時,語音和語韻的錯誤。」美國聽語學會(2007)
