Reading Performance as a Function of Treatment With Lisdexamfetamine Dimesylate in Elementary School Children Diagnosed With ADHD
Abstract
Background: Medication treatment studies of ADHD have typically not assessed effects on reading performance, although reading difficulties frequently co-occur in children with ADHD. The current study characterizes the effects of lisdexamfetamine dimesylate (LDX; Vyvanse ® , Shire US Inc.), at peak efficacy, on reading performance in children with ADHD. Method: Children (ages 6-12; N = 26) with ADHD enrolled in a modified laboratory school study with an open-label, dose-optimization phase of LDX (30-70 mg/d). The Gray Oral Reading Test-4 (GORT-4) with measures of rate, accuracy, and comprehension was administered at baseline and 3-4 hr postdose, following 4 to 5 weeks of optimal dose titration. Results: Treatment reduced ADHD symptoms. Reading rate was improved, especially among children with higher verbal fluid reasoning without additional symptoms of neurodevelopmental delay. No differences were observed for reading accuracy or comprehension. Conclusion: Endophenotypical profiles may predict drug effects in specific skill areas, such as reading rate.

In Wigal et al open-label dose-optimization study of 26 children with ADHD, lisdexamfetamine 30-70 mg produced improvements in rate, accuracy, and comprehension measures on the Gray Oral Reading Test-4 after 4-5 weeks of treatment.
“Wigal et al34 demonstrated improvements in rate, accuracy, and comprehension measures on the Gray Oral Reading Test-4 performed at baseline and after 4–5 weeks of treatment in a “modified laboratory school” setting.”

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.
