Word length and error types in Japanese left-sided neglect dyslexia.

Seven patients who showed left-sided neglect in reading single words were examined. Neglect errors typically involved omission of initial letters in our patients. Two patients with enough errors had a tendency that longer words were more susceptible to errors than short words. Most of the patients were less affected than the patients in the previous reports. Japanese people read strings of letters written not only from left to right but also from right to left. The seven patients continued to misread the letters on the left end when asked to read words from right to left. The two patients showed a significant deficit in reading words from left to right compared to reading from right to left.
