RIGHT THALAMIC INJURY, IMPAIRED VISUOSPATIAL PERCEPTION, AND ALEXIA NEUROLOGY Henderson, V. W., Alexander, M. P., Naeser, M. A. 1982; 32 (3): 235-240

Abstract

In pure alexia, acquired inability to read contrasts with normal speech and handwriting. Rare cases of right hemisphere lesions causing this syndrome are usually attributed to right hemisphere dominance for language. After infarction of the right occipital lobe and thalamus, a fully right-handed man became alexia, but language and spontaneous and dictated writing were intact. Left hemispatial neglect and constructional disturbances were marked, and we suggest that pure alexia was mimicked by the impairment in visuospatial perception. Injury of the nondominant hemisphere and thalamus together may have been important in causing these deficits.
