A patient with difficulty of object recognition: semantic amnesia for manipulable objects.
We studied a patient who had recognition difficulty for manipulable objects. MRI showed a lesion in the left occipito-parietotemporal area. Differential diagnosis of agnosia, aphasia and apraxia is discussed. We believe this "object meaning amnesia" constitutes a distinct subtype of semantic amnesia.
