title: [Neglect dyslexia owing to traumatic fronto-temporal right hemisphere bleeding].
abstract: Apart from unilateral disturbance of the egocentric reference system, as it is traditionally known of neglect, there are also cases with unilateral disturbances of a stimulus-centered or object-centered reference system. In these cases the spatial position of the object, from the observer's perspective, plays only a limited role in the explanation of the problems with object perception. We describe a patient who, following head-brain trauma and a fronto-temporal bleeding, showed, beside traditional neglect, also a stimulus-centered left-sided disorder in word and object perception. Our investigations showed that this disorder (a) is independent of the position of the object in the environmental space, (b) comprises words and objects, and (c) is especially sensitive for changes in the first letters of a word. Conclusively, it yields from this case that at least three different reference systems of object representation should be distinguished in neglect, which can be disturbed independently from each other and may negatively influence the behavioral potential of the patients.
