Comorbidity of tic disorders & ADHD: Conceptual and methodological considerations

Banaschewski, Tobias, Neale, Benjamin M., Rothenberger, Aribert, Roessner, Veit·2007·European Child & Adolescent Psychiatry

Abstract

Background The causes and pathophysiological mechanisms of the common comorbidity of tic disorders and Attention-deficit/Hyperactivity disorder (TD + ADHD; about 50% of TD, about 20% of ADHD) still remain unclear. Studies with a 2 x 2 design comparing groups of children with TD, ADHD, TD + ADHD and healthy controls are in need and may disentangle the influences of TD versus ADHD in the case of comorbidity. Unfortunately, conceptual and methodological problems can restrain possible conclusions from these studies.Method A review of the literature on artifactual and non-artifactual models of comorbidity in general and specially for TD + ADHD was conducted.Results The first section describes various possible models of comorbidity and their corresponding hypotheses concerning expected patterns of findings comparing groups of children with TD, ADHD, TD + ADHD and healthy controls. In the second part research results concerning psychopathological, neuropsychological, neurophysiological, structural and functional imaging, as well as genetic characteristics are summarized. In the third section possible conclusions and their limitations due to conceptual and methodological problems possibly contributing to the ambiguous results are discussed. Finally, future research strategies and the need for full causal models are outlined.Conclusion Some components of the etiological pathways of TD + ADHD may well be shared with the 'pure' conditions while others may be unique.

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.
