Childhood apraxia of speech

Disease definition

A rare neurologic disease characterized by impaired ability to execute complex coordinated movements underlying the production of speech, leading to highly unintelligible speech in the absence of muscular or sensory deficits. Initial presentation may be a severe expressive speech delay.
