Fast versus slow onset of depressive episodes: A clinical criterion for subtyping patients with major depression
Published online by Cambridge University Press: 15 April 2020
Abstract
The speed of onset of depressive episodes is a clinical aspect of affective disorders that has not been sufficiently investigated. Thus, we aimed to explore whether patients with fast onset of the full-blown depressive symptomatology (≤ 7 days) differ from those with slow onset (> 7 days) with regard to demographic and clinical aspects.
Data were obtained within an observational study conducted in outpatients with major depression who were treated with duloxetine (30–120 mg/day). Onset of depression (without any preceding critical life event) was fast in 416 (less than one week) and slower in 2220 patients.
Compared to patients with slow onset, those with fast onset of depression had more suicide attempts in the previous 12 months (2.7% versus 1.3%, P = 0.046) and less somatic comorbidity (61.7% versus 74.1%, P < 0.0001). In addition, they were slightly younger at onset of depression (mean ± SD 40.2 ± 14.6 versus 42.8 ± 14.2 years, P < 0.001) and used analgesics at baseline significantly less frequently (22.8% versus 33.4%, P < 0.0001).
The speed of onset of depression has to be regarded as a relevant clinical characteristic in patients with unipolar depression.
