[Prolonged grief disorder].

Abstract

Grief is a natural response to the loss of a loved one and its intensity usually lessens over time. Approximately 10% of bereaved persons, however, experience persistent symptoms resulting in the development of a prolonged grief disorder (PGD). A PGD shows a distinct symptom cluster and is considered for inclusion as a diagnosis in the upcoming revision of the International Statistical Classification of Diseases and Related Health Problems (ICD-11). It is distinct from other mental disorders but symptoms overlap, especially with major depression and posttraumatic stress disorder. In addition to diagnostic criteria and differential diagnosis, the following article also describes prevalence rates, comorbidities, risk factors as well as treatment options for PGD.
