What role for prism adaptation in the rehabilitation of pure neglect dyslexia?

ABSTRACT

Prism adaptation (PA) has been successfully applied in the rehabilitation of spatial neglect, with significant transfer to classic neglect tests and activities of daily living. However, well-controlled studies were unable to replicate these findings, and recent reports suggest that PA may affect selectively visuo-motor symptoms. Here, a patient with pure left neglect dyslexia was tested before, immediately after, and 24 h after PA. Despite a significant adaptation aftereffect adaptation had no effect omissions, substitutions and letter-based errors. PA does not affect pure neglect dyslexia and should therefore be reserved for the rehabilitation of motor-intentional, rather than visual-attentional symptoms.
