Apraxia and agraphia in a right-hander.

Summary This paper presents a case of a right-handed man who developed a right hemiplegia, without aphasia, and also demonstrated an agraphia and an apraxia. Analysis of this case suggests that although in this man the right hemisphere was dominant for language, the left hemisphere was dominant for handedness. The lesion in the left hemisphere destroyed the engrams for complex motor activity and was responsible for this patient's apraxia and agraphia.
