Complicated Grief Disorder: Symptoms, Diagnosis, and Treatment
By CRYSTAL BAI •
The short answer: Complicated grief (now called Prolonged Grief Disorder) occurs when intense grief symptoms persist beyond 12 months and significantly impair daily functioning. It affects roughly 10% of bereaved people and responds well to specialized therapy.
What Is Complicated Grief?
Complicated grief — officially termed Prolonged Grief Disorder (PGD) in the DSM-5-TR — is a condition where grief remains intense and impairing long after a loss, rather than gradually integrating. It's distinct from normal grief and from depression or PTSD, though it can co-occur with both.
DSM-5 Diagnostic Criteria
PGD requires:
- The death of someone close occurring at least 12 months ago (6 months for children)
- At least one of: intense yearning/longing for the deceased, or preoccupation with the deceased or circumstances of the death
- At least three of: difficulty accepting the death, emotional numbness, feeling that life is meaningless, bitterness or anger, identity disruption, avoiding reminders, difficulty engaging in life
- These symptoms cause significant impairment in functioning
Risk Factors
- Sudden, traumatic, or violent death
- Death of a child
- Suicide loss
- History of attachment difficulties or prior trauma
- Lack of social support
- Multiple losses in a short period
Treatment: What Works
Complicated Grief Treatment (CGT) — developed at Columbia University — is the gold-standard evidence-based therapy. It combines elements of cognitive behavioral therapy with grief-specific interventions like revisiting the story of the death, working toward restoration goals, and imaginal conversations with the deceased.
Studies show CGT significantly outperforms standard depression treatment for PGD. Antidepressants (particularly escitalopram) can help with co-occurring depression, though they don't treat PGD directly.

Frequently Asked Questions
What is complicated grief disorder?
Complicated grief — clinically called Prolonged Grief Disorder (PGD) — is a condition where intense grief persists beyond 12 months (6 months in children) and significantly impairs daily functioning. It affects roughly 10% of bereaved people.
What are the symptoms of complicated grief?
Key symptoms include intense yearning for the deceased, difficulty accepting the death, emotional numbness, feeling life is meaningless, identity disruption, social withdrawal, and avoiding reminders of the loss — persisting well beyond the normal grief period.
How is complicated grief different from depression?
Depression involves pervasive low mood and often a loss of self-worth. Complicated grief is characterized specifically by intense longing for the deceased and preoccupation with the loss. They can co-occur, but their treatments differ.
What is the treatment for complicated grief?
Complicated Grief Treatment (CGT), developed at Columbia University, is the leading evidence-based approach. It combines cognitive-behavioral techniques with grief-specific interventions and significantly outperforms standard depression therapy for PGD.
When does grief become a disorder?
When grief symptoms remain intense and impairing for more than 12 months after loss (per DSM-5 criteria for Prolonged Grief Disorder), it may warrant clinical diagnosis and specialized treatment. Earlier intervention is appropriate when symptoms severely disrupt functioning.
