Abstract

OBJECTIVE: 342 Caucasian subjects with attention deficit/hyperactivity disorder (ADHD) were recruited from pediatric and behavioral health clinics for a genetic study. Concurrent comorbidity was assessed to characterize the clinical profile of this cohort. METHODS: Subjects 6 to 18 years were diagnosed with the Schedule for Affective Disorders & Schizophrenia for School aged Children (K-SADS-P IVR). RESULTS: The most prevalent diagnoses co-occurring with ADHD were Oppositional Defiant Disorder (ODD) (40.6%), Minor Depression/Dysthymia (MDDD) (21.6%), and Generalized Anxiety Disorder (GAD) (15.2%). In Inattentive ADHD (n = 106), 20.8% had MDDD, 20.8% ODD, and 18.6% GAD; in Hyperactive ADHD (n = 31) 41.9% had ODD, 22.2% GAD, and 19.4% MDDD. In Combined ADHD, (n = 203), 50.7% had ODD, 22.7% MDDD and 12.4% GAD. MDDD and GAD were equally prevalent in the ADHD subtypes but, ODD was significantly more common among Combined and Hyperactive ADHD compared to Inattentive ADHD. The data suggested a subsample of Irritable prepubertal children exhibiting a diagnostic triad of ODD, Combined ADHD, and MDDD may account for the over diagnosing of Bipolar Disorder. CONCLUSION: Almost 2/3rd of ADHD children have impairing comorbid diagnoses; Hyperactive ADHD represents less than 10% of an ADHD sample; ODD is primarily associated with Hyperactive and Combined ADHD; and, MDDD may be a significant morbidity for ADHD youths from clinical samples.

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?

  • Boys with ADHD are more likely to exhibit externalizing conditions like oppositional defiant disorder or conduct disorder.

    “Boys are more likely to exhibit externalizing conditions like oppositional defiant disorder or conduct disorder.17,19,20”

    From Clinical Practice Guideline for the Diagnosis, Evaluation, and Treatment of Attention-Deficit/Hyperactivity Disorder in Children and Adolescents (2019) · cites this paper as [17]

    The Results report no significant sex differences in the diagnostic frequency patterns, including oppositional defiant disorder; the only exception was separation anxiety, which was more common in girls. The paper therefore does not support the claim that boys with ADHD are more likely than girls to have these externalizing conditions. (LLM, conf=0.90)

    Checked by a reasoning model — may be wrong.

  • The majority of both boys and girls with ADHD also meet diagnostic criteria for another mental disorder.

    “The majority of both boys and girls with ADHD also meet diagnostic criteria for another mental disorder.17,18”

    From Clinical Practice Guideline for the Diagnosis, Evaluation, and Treatment of Attention-Deficit/Hyperactivity Disorder in Children and Adolescents (2019) · cites this paper as [17]

    The Results report that 36.3% of the ADHD sample had no additional diagnosis, so a majority had at least one. The paper does not report this proportion separately for boys and girls; its statement that most diagnostic frequency patterns did not differ significantly by sex does not establish a majority in each group. The sample was also a selected clinical cohort. (LLM, conf=0.84)

    Experimental — accuracy not yet measured

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.
