Prolonged Grief Symptoms Predict Social and Emotional Loneliness and Depression Symptoms.

A minority of bereaved individuals develops severe, persistent, and disabling grief, termed "prolonged grief." The International Classification of Diseases, eleventh edition (ICD-11) and the Diagnostic and Statistical Manual of Mental Disorders, fifth edition, text revision (DSM-5-TR) include such grief reactions as prolonged grief disorder (PGD). Loneliness is often experienced by bereaved persons and can have severe health consequences.
