Forty—six dyslexic boys, aged 8-13 years, were administered Piracetam or placebo in a double blind, parallel experiment, lasting 8 weeks. Although, overall, there were no significant group effects,the within—subject design revealed improvements in reading speed and accuracy in individuals treated with Piracetam. Also,stratifying the groups by group means revealed that dyslexics with higher reading ages improved significantly compared to the placebo group.
