[Grief, evolution of new definitions]

The concept of pathological grief is a controversial issue. Bereavement is a universal experience, and its association with excess morbidity and mortality is well established. Complicated grief is a process that by its length or intensity is considered pathological but not considered as a distinct mental disorder in the present international classifications: ICD-10 and DSM-IV-TR. For some individuals, if intense grief persists, is distressing and disabling, and may meet criteria as a distinct mental disorder. This definition evolved with the implementation of a proposed criteria for a persistent complex bereavement disorder in the section of "condition of further study"s of the new DSM-5 after the debate raised by the proposition of several authors to include a distinct mental disorder. We tried to illustrate that complex question with a non exhaustive review and with a case report of a clinical situation of a female that was treated in a crisis center in Geneva, following the sudden death of her husband.
