ideomotor apraxia /īdē″əmō″tor/ [Gk, idea + L, motare, to move about; Gk a + prassein, not to do] , the inability to translate an idea into motion, resulting from some interference with the transmission of the appropriate impulses from the brain to the motor centers. There is no loss of the ability to perform an action automatically, such as tying the shoelaces, but the action cannot be performed on request. The condition is often caused by diffuse cortical disease. Also called ideokinetic apraxia, limb kinetic apraxia, transcortical apraxia. See also apraxia.
