Loss of deep dyslexic reading ability from a second left-hemispheric lesion.
It has been hypothesized that the residual reading ability in people with deep dyslexia (an acquired dyslexia in which the subjects make semantic paralexias, eg, child read as boy) utilizes right hemispheric structures. A patient who was deep dyslexic following an initial left hemispheric stroke was studied. Following a new left hemispheric stroke, he lost his residual reading ability. In this patient, deep dyslexic reading abilities were dependent on left hemispheric structures.
