Does Modafinil Enhance Cognitive Performance in Young Volunteers Who Are Not Sleep-Deprived?
Abstract : In a double-blind , parallel groups study , 60 healthy student volunteers ( 29 men and 31 women , aged 19 - 22 years ) were r and omly allocated to receive placebo , 100 or 200 mg modafinil . Two hours later , in the early evening , they completed an extensive cognitive battery . The 3 groups did not differ in self-ratings of sleepiness or tiredness before the testing session , and there were no treatment-associated changes in these or in mood ratings during the tests . Modafinil was without effect in several tests of reaction time and attention , but the 200-mg group was faster at simple color naming of dots and performed better than placebo in the Rapid Visual Information Processing test of sustained attention . Modafinil was without effect on spatial working memory , but the 100-mg group performed better in the backward part of the digit span test . Modafinil was without effect on verbal short-term memory ( story recall ) , but 100 mg improved digit span forward , and both doses improved pattern recognition , although this was accompanied by a slowing of response latency in the 200-mg group . There were no significant effects of modafinil compared with placebo in tests of long-term memory , executive function , visuospatial and constructional ability , or category fluency . These results suggest that the benefits of modafinil are not clearly dose-related , and those from 100 mg are limited to the span of immediate verbal recall and short-term visual recognition memory , which is insufficient for it to be considered as a cognitive enhancer in non-sleep-deprived individuals
