Childhood adversities in patients with fibromyalgia: are they related to comorbid lifetime major depression?

Fibromyalgia (FM) is a syndrome of unknown aetiology that is frequently associated with depressive disorders, and childhood adversities (including maltreatment and parental loss) are frequently described in subjects with FM and depression. The aim of this study was to investigate the extent to which the high percentage of childhood adversities reported by patients with FM is related to FM itself or to a comorbid lifetime depressive disorder.
