Background:

Evidence suggests that diagnostic delay from first episode of illness may be many years. Treating illness early in its time course is associated with a better prognosis.

Methods:

Participants (n = 240) were enrolled in the Bipolar Comprehensive Outcomes Study (BCOS). A questionnaire was devised to collect information about participants from their first onset of symptoms of mental illness to when they received a diagnosis of bipolar disorder or schizoaffective disorder. The questionnaire was administered at interview by BCOS researchers when the participant was euthymic.

Results:

Symptoms of mental illness were first experienced at 20.17 ± 10.26 years (mean ± SD; n = 207) and mood swings at 21.19 ± 11.76 years (mean ± SD; n = 191). Symptoms of depression were first experienced at 21.11 ± 9.98 years (mean ± SD; n = 195), a full episode of depression at 23.64 ± 9.76 years (mean ± SD; n = 191), symptoms of mania at 24.24 ± 11.48 years (mean ± SD; n = 202) and a full episode of mania at 26.43 ± 10.41 years (mean ± SD; n = 196). Medical treatment was first sought at 26.26 ± 10.18 years (mean ± SD; n = 207). Participants first received a diagnosis of bipolar disorder or schizoaffective disorder at 31.43 ± 11.34 years (mean ± SD; n = 206). Having had a previous diagnosis other than bipolar disorder or schizoaffective disorder was reported by 116 of 206 participants who answered this question.

Conclusions:

Prior to being diagnosed and treated for bipolar disorder or schizoaffective disorder, participants typically experience a long time course of symptoms, episode and treatments.
