Dyspraxia is an impairment or immaturity in the way that the brain processes information, which results in messages not being properly or fully transmitted affecting the organisation of movement.
The term dyspraxia comes from the word praxis, which means 'doing' or 'acting'.
Dyspraxia affects the planning of what to do and how to do it. It is associated with problems of perception, language and thought.

Apraxia is a motor speech disorder.
Such children have problems saying sounds, syllables, and words. This is not because of muscle weakness or paralysis but because the brain has problems planning to move the body parts (e.g., lips, jaw, tongue) needed for speech.
The child knows what he or she wants to say, but his/her brain has difficulty coordinating the muscle movements necessary to say those words.
