[Review] Prolonged grief disorder

Prolonged grief disorder is a mental health disorder recently included in diagnostic manuals worldwide. This Review presents published research evidence in strong support for the current conceptualisation of prolonged grief disorder: a diagnosable mental health condition with core symptoms of yearning, preoccupation, or both, which is associated with symptoms of emotional pain, identity disturbances, loss of meaning and purpose, and functional impairment. The public and academic discourse surrounding prolonged grief disorder has catalysed researchers to produce methodologically rigorous research evidence in support of this much-needed diagnosis.
