Scotopic sensitivity in dyslexia and requirements for DHA supplementation

Lancet. 2000 Apr 22;355(9213):1429-30. doi: 10.1016/s0140-6736(00)02145-0.

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.
