ABSTRACT
Apraxia is one of classical neuropsychological deficits. The term apraxia was used by Steinthal and Geschwind proposed the following definition in 1975: 'the apraxias are disorders of the execution of learned movements which cannot be accounted for either by weakness in coordination or sensory loss, nor by incomprehension of or inattention to commands'. In adults, apraxia is often apparent after left hemisphere stroke, but it is seen in patients with Alzheimer's disease, Huntington's disease, and it is one of the symptoms of corticobasal degeneration. Dyspraxia is a developmental disorder seen in children and characterised by an impairment of organization and planning of movement. Children who have childhood apraxia of speech (CAS) find it very difficult to make sounds in the right order, which makes it hard for others to understand them. Recently, Murray et al. conducted a review into treatment outcomes for children and they were able to recommend three treatment methods on the basis of single case experimental research.
