ADHD in adults: A study of clinical characteristics, impairment and comorbidity

Torgersen, Terje, Gjervan, Bjørn, Rasmussen, Kirsten·2006·Nordic Journal of Psychiatry

Abstract

In this study, we explored the clinical characteristics, impairment and comorbidity in a sample of 45 adult patients with attention-deficit/hyperactivity disorder (ADHD). The collection of data is based on a naturalistic, retrospective approach using medical records documenting a comprehensive assessment of the patients. The sample was severely impaired in terms of academic achievement, employment and criminality, and had very high levels of comorbidity, especially alcohol and drug abuse, antisocial personality disorder and depression. Despite a high degree of contact with child psychiatric services in childhood, very few were diagnosed with ADHD, and many had a long period of psychiatric treatment as adults before the ADHD diagnosis was made. ADHD is in this sample of adults associated with severe impairment and comorbidity, and the connection between impairment and lack of proper diagnosis and treatment is discussed.

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.
