Visual Agnosia and Alternating Dominance; Analysis of a Case

Abstract

The case here described is of interest in that it concerns a young man of good intelligence who presented a disorder limited to visual-gnostic functions; this is noteworthy as the majority of the cases described are elderly patients and there are usually other than visual gnostic functions involved. The case has special circumstances of additional significance. The patient had lost the sight of his right eye in infancy and he was a definite right-handed man; the damage involved the right hemisphere; this exceptional coincidence raises interesting problems of hemispheric dominance.
