Abstract

Background There are obstacles to early identification of bipolar disorder. Identifying and treating illness early in its time course may be associated with a better prognosis.Methods A questionnaire was administered at interview, when the participant was euthymic, to participants (n=240) enrolled in the Bipolar Comprehensive Outcomes Study (BCOS). Information was collected about the sequential timeline of specific symptoms of mental illness up to when they first received a diagnosis of Bipolar Disorder or Schizoaffective Disorder.Results Any symptoms of mental illness were first experienced at 17.5 years (median; Inter Quartile Range (IQR) 13.8-24.3; n=216) and mood swings at 18.0 years (IQR 14-25; n=197). Symptoms of depression were experienced at 18.0 years (IQR 14-25; n=197), a full episode of depression at 21.2 years (IQR 17-28.5; n=200), symptoms of mania at 21.0 years (IQR 16.8-29.5; n=212) and a full episode of mania at 24.1 years (IQR 19-30.5; n=205). Medical treatment was sought at 24.0 years (IQR 19-31.5; n=217). Participants received a diagnosis of Bipolar Disorder or Schizoaffective Disorder at 30.0 years (IQR 23-37.3; n=215). Having had a previous diagnosis other than Bipolar Disorder or Schizoaffective Disorder was reported by 120 of 216 participants who answered this question, most commonly unipolar depression (26.6%). Diagnostic delay was greater in individuals with early onset disorder.Conclusions Participants typically experience a long sequential course of symptoms, episodes, treatments and diagnosis. The polarity of onset is most commonly depressive, and subthreshold symptoms tend to precede threshold symptoms of both polarities.Limitations Data were collected retrospectively.

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.
