Disruption of residual reading capacity in a pure alexic patient after a mirror-image right-hemispheric lesion

Abstract

A 74-year-old woman became a letter-by-letter reader after the occurrence of a left occipito-temporal hematoma. Seven months later, she suffered a second, mirror-image hematoma in the right hemisphere. After this second lesion, her residual reading capacity deteriorated dramatically in terms of both accuracy and reading latencies for words and isolated letters. Our findings support the hypothesis that the right hemisphere contributes to the residual reading capacities of pure alexic patients.
