Unidirectional dyslexia in a polyglot

J Neurol Neurosurg Psychiatry. 1999 Apr;66(4):517-9. doi: 10.1136/jnnp.66.4.517.

Abstract

Alexia is usually seen after ischaemic insults to the dominant parietal lobe. A patient is described with a particular alexia to reading Hebrew (right to left), whereas no alexia was noted when reading in English. This deficit evolved after a hypertensive right occipitoparietal intracerebral haemorrhage, and resolved gradually over the ensuing year as the haematoma was resorbed. The deficit suggests the existence of a separate, language associated, neuronal network within the right hemisphere important to different language reading modes.
