A case of ideational apraxia with impairment of object use and preservation of object pantomime.

A case of tool use disturbance without impairment of motor skills and of conceptual knowledge of how tool must be used is reported. The patient could not manipulate objects isolatedly or in succession but could pantomime their use on command and on imitation. This finding suggests that manipulation of objects may dissociate from pantomime without objects. We interpret this syndrome as a results of mismatch of tool and tool use.
