Rapid Visual Information Processing as a Cognitive Endophenotype of Attention Deficit Hyperactivity Disorder

Gau, S. S.-F., Huang, W.-L.·2014·Psychological Medicine

Abstract

BACKGROUND: Deficits in sustained attention and reaction time are core features of attention deficit hyperactivity disorder (ADHD). However, little is known about attention performance in unaffected siblings. Hence, we examined sustained attention and reaction time in youths with ADHD, unaffected siblings and controls to test whether impaired performance in attention tasks can be a potential endophenotype of ADHD. METHOD: We recruited 438 probands with clinical diagnosis of ADHD according to DSM-IV criteria, 180 unaffected siblings, and 173 healthy controls without lifetime ADHD. They were assessed using psychiatric interviews, Conners' Continuous Performance Test, and the tasks involving attention performance of the Cambridge Neuropsychological Test Automated Battery (CANTAB): Rapid Visual Information Processing (RVP), Reaction Time (RTI) and Match to Sample Visual Search (MTS). Multi-level models were used for data analysis. RESULTS: Compared with the controls, probands with ADHD and unaffected siblings had significantly higher total misses, lower probability of hits in the RVP task and probands with ADHD performed worse in the RTI and MTS tasks after controlling for sex, age, co-morbidity, parental educational levels and IQ. The duration of methylphenidate use and IQ but not psychiatric co-morbidity or current use of methylphenidate were associated with deficits in sustained attention in probands with ADHD. CONCLUSIONS: Our findings suggest that attention performance assessed by the RVP task, but not the RTI or MTS tasks, of the CANTAB may be a useful cognitive endophenotype for ADHD genetic studies.

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • In children and adolescents with ADHD, cognitive deficits have mainly been found regarding working memory and processing speed.

    “In children and adolescents with ADHD, cognitive deficits have mainly been found regarding working memory (Kasper et al. 2012; Martinussen et al. 2005) and processing speed (Gau and Huang 2014; Salum et al. 2014; Shanahan et al. 2006).”
  • The worse performance of children and adolescents with ADHD on WMI and PSI is in line with previous research highlighting decreased working memory capacity and limitations in processing speed in ADHD.

    “The worse performance of children and adolescents with ADHD on WMI and PSI is in line with previous research highlighting a decreased working memory capacity in children with ADHD (Kasper et al. 2012; Martinussen et al. 2005) and limitations in processing speed (Gau and Huang 2014; Salum et al. 2014; Shanahan et al. 2006).”
  • Behavioral problems and cognitive deficits of children and adolescents with ADHD may likely manifest themselves in performances primarily associated with working memory and processing speed.

    “As described previously, the behavioral problems and cognitive deficits of children and adolescents with ADHD may likely manifest themselves in performances primarily associated with working memory and processing speed (Gau and Huang 2014; Kasper et al. 2012; Martinussen et al. 2005; Salum et al. 2014; Shanahan et al. 2006).”

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.
