People can be unable to make purposeful skilled movements and to move in response to verbal commands {apraxia, muscle disease}, though they can comprehend words.
types
People can persevere in making distorted movements {ideomotor apraxia}, use previous movements in current movements, and show no difference between left and right limbs or meaningful and meaningless tasks.
People can have impaired motor-element selection and sequencing {ideational apraxia}, caused by problems in brain association areas that input to motor programs.
brain
Disconnecting Wernicke's area from motor centers causes apraxia. Language-hemisphere lesions impair action sequences. Animal brain lesions do not cause apraxia.
comparison
Aphasia and apraxia have no qualitative relation.
