Abstract:

Much interest is shown in reduced scotopic sensitivity in dyslexia and the possible role of docosahexaenoic-acid deficiency as a causative factor. However, we found that significant decreases in scotopic sensitivity are not a general characteristic of dyslexia, which may cast doubt on the value of DHA supplementation.
