Abstract

OBJECTIVE: The objective of this research was to explore the effects of risperidone on cognitive processes in children with autism and irritable behavior. METHOD: Thirty-eight children, ages 5-17 years with autism and severe behavioral disturbance, were randomly assigned to risperidone (0.5 to 3.5 mg/day) or placebo for 8 weeks. This sample of 38 was a subset of 101 subjects who participated in the clinical trial; 63 were unable to perform the cognitive tasks. A double-blind placebo-controlled parallel groups design was used. Dependent measures included tests of sustained attention, verbal learning, hand-eye coordination, and spatial memory assessed before, during, and after the 8-week treatment. Changes in performance were compared by repeated measures ANOVA. RESULTS: Twenty-nine boys and 9 girls with autism and severe behavioral disturbance and a mental age >or=18 months completed the cognitive part of the study. No decline in performance occurred with risperidone. Performance on a cancellation task (number of correct detections) and a verbal learning task (word recognition) was better on risperidone than on placebo (without correction for multiplicity). Equivocal improvement also occurred on a spatial memory task. There were no significant differences between treatment conditions on the Purdue Pegboard (hand-eye coordination) task or the Analog Classroom Task (timed math test). CONCLUSION: Risperidone given to children with autism at doses up to 3.5 mg for up to 8 weeks appears to have no detrimental effect on cognitive performance.

  • Randomized controlled trials of risperidone in individuals with ASD found significant reductions in challenging behaviors, such as irritability and hyperactivity.

    “randomized controlled trials of risperidone in individuals with ASD found significant reductions in challenging behaviors, such as irritability and hyperactivity [596-600]”
  • The ASD and ADHD studies that reported cognitive or IQ improvements were conducted in individuals who were intellectually higher functioning than typical male patients with fragile X syndrome.

    “However, these studies were conducted in individuals who were intellectually higher functioning than typical male patients with FXS.”
  • Evidence of cognitive improvement has not yet been unequivocally demonstrated in randomized controlled trials evaluating pharmacological treatments for neurodevelopmental disorders.

    “Evidence of cognitive improvement has not yet been unequivocally demonstrated in RCTs that evaluate pharmacological treatments in NDDs.”
  • In autism spectrum disorder and attention deficit hyperactivity disorder, pharmacological randomized controlled trials and behavioural interventions have reported improvements in cognitive processing measures and IQ after 3 to 12 months of treatment.

    “In ASD and attention deficit hyperactivity disorder, improvement in measures of cognitive processing (verbal learning and cancellation task) and IQ have been reported in pharmacological RCTs after 3–12 months of treatment and behavioural interventions88–91.”

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.
