The mourning process and its importance in mental illness: a psychoanalytic understanding of psychiatric diagnosis and classification

This article brings together the psychiatric and psychoanalytic views of mental illness to deepen the understanding of mental disorder. The intention is to bring to the fore the importance of loss and mourning in clinical practice. Looking for the loss event that underpins the disorder helps determine therapeutic treatment options and increases the chance of authentic therapeutic engagement and recovery. The article summarises theory about the mourning process and discusses the relationship of loss and pathological mourning to mental illness. Fictitious case vignettes developed from years in psychiatric practice are used to illustrate how this relates to clinical practice and formulation.
