Definitions for "apraxia"
inability to make purposeful movements, but without paralysis or loss of sensory function.
ay-PRAX-ee-uh Difficulty with volitional (deliberate) movement planning and sequencing, in the absence of actual muscle weakness or incoordination. Limb Apraxia involves arm or leg movements; Oral Apraxia involves oral mechanism (tongue, lips, jaws) movements; Verbal Apraxia (also known as Apraxia of Speech) involves speech sound production and sequencing difficulties.
Loss of the ability to sequence, coordinate, and execute certain purposeful movements and gestures in the absence of motor weakness, paralysis, or sensory impairments. Apraxia is thought to result from damage to the cerebral cortex, such as due to stroke, brain tumors, head injury, or infection. It may also occur as a result of impaired development of the cortex as in certain neurodevelopmental disorders, including Rett syndrome. Apraxia may affect almost any voluntary movements, including those required for proper eye gaze, walking, speaking, or writing.
