The two major subtypes of this condition are ideomotor (see APRAXIA,IDEOMOTOR) and ideational apraxia,which refers to loss of the ability to mentally formulate the processes involved with performing an action. For example,dressing apraxia may result from an inability to mentally formulate the act of placing clothes on the body. Apraxias are generally associated with lesions of the dominant PARIETAL LOBE and supramarginal gyrus.
