Abstract

A growing body of literature has examined the cognitive effects of immediate-release methylphenidate in children with attention-deficit/hyperactivity disorder (ADHD). However, a clear understanding of the types and magnitude of such effects are difficult to discern from such a large and varied collection of published reports. This review evaluated a total of 40 relevant placebo-controlled studies published since Rapport and Kelly's [1993. Psychostimulant effects on learning and cognitive function. In: Matson, J.L. (Ed.), Handbook of Hyperactivity in Children. Allyn & Bacon, Boston, pp. 97-136] original review of cognitive effects of methylphenidate in children with ADHD. Of these published studies, 63.5% identified some improvement in cognitive function following methylphenidate treatment. Methylphenidate improved performance on saccadic eye movement, planning/cognitive flexibility, attention/vigilance, and inhibitory control tasks in 83.3%, 71.4%, 70.6%, and 69.7% of studies, respectively. A total 58.3% and 50% of studies that evaluated the effect of methylphenidate on tasks of memory and working memory/divided attention, respectively, noted improvement. Variability of findings across studies may be explained by differential effects of methylphenidate on brain function, intra- and inter-individual variability in medication response, methodological limitations, and problems associated with repeated neuropsychological assessment and metric properties of commonly utilised neuropsychological instruments.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
