Apraxias are deficits of higher motor behavior that are not primarily caused by sensorimotor dysfunction, or communication problems, or dementia. A patient with apraxia does not know what to do, because the plan of action is disrupted, or in other cases, the patient knows what to do but not how to do it. A variety of forms of apraxia originate from lesions of different levels and structures of the motor system, reflecting its complexity. The multifarious types of apraxia differentially affect the activities of daily living and hence show marked differences in the prognosis of recovery and the need of treatment. Therefore, objective diagnosis and appropriate treatment of the different types of apraxia are of foremost clinical importance. In this paper, we reviewed the current literature on the assessment and treatment of apraxia.
