What Is Complicated Grief and When Should You Get Help?
By CRYSTAL BAI •
The short answer: Complicated grief (also called prolonged grief disorder or persistent complex bereavement disorder) is grief that remains intensely disabling for more than 12 months after a loss — or 6 months for children. It affects about 10% of bereaved people. Unlike normal grief, complicated grief doesn't gradually lessen; it stays raw, intrusive, and disabling. Evidence-based treatment (Complicated Grief Treatment, or CGT) significantly helps.
Normal Grief vs. Complicated Grief
Normal grief is painful, but it changes over time. It comes in waves, gradually loosening its grip, allowing the bereaved person to re-engage with life while integrating the loss. Complicated grief does not follow this pattern — it stays acute, consuming, and interferes with basic functioning for an extended period.
| Feature | Normal Grief | Complicated Grief |
|---|---|---|
| Duration of acute phase | Weeks to months, with gradual improvement | Persists at high intensity 12+ months |
| Ability to function | Impaired but recovers | Ongoing severe impairment |
| Intrusive thoughts | Present but decrease over time | Persistent, unwanted, consuming |
| Avoidance | Some avoidance of reminders | Extreme avoidance or inability to accept death occurred |
| Future orientation | Gradually returns | Feels pointless or impossible |
Warning Signs of Complicated Grief
- Intense longing and yearning for the deceased that doesn't diminish
- Difficulty accepting that the death occurred
- Bitterness, anger, or guilt that does not resolve
- Inability to trust others since the loss
- Feeling that life is meaningless or purposeless without the person
- Avoiding reminders of the deceased or, conversely, being unable to stop focusing on them
- Significant impairment in work, relationships, or daily functioning after 12+ months
Who Is at Higher Risk
Risk factors for complicated grief include: sudden or traumatic death, suicide loss, loss of a child, ambivalent or dependent relationship with the deceased, prior mental health history, lack of social support, and multiple concurrent losses.
Effective Treatment
Complicated Grief Treatment (CGT), developed by Columbia University's Center for Prolonged Grief, is the gold-standard evidence-based treatment — a specialized form of therapy that reduces grief symptoms significantly. Prolonged grief disorder was added to the DSM-5-TR in 2022, expanding insurance coverage for treatment. Find a CGT-trained therapist at the Columbia Center for Prolonged Grief website.
Frequently Asked Questions
What is the difference between complicated grief and depression?
They can co-occur, but complicated grief is specifically about the loss — the yearning, preoccupation with the deceased, and difficulty accepting death. Depression involves more global hopelessness and anhedonia. Both can be present simultaneously and both are treatable.
Is prolonged grief disorder the same as complicated grief?
Yes. Prolonged grief disorder (PGD) is the current clinical term in the DSM-5-TR (added 2022). Complicated grief (CG) and persistent complex bereavement disorder (PCBD) were earlier terms for the same condition.
Can I recover from complicated grief without therapy?
Some people recover with strong social support and time. However, research shows that specialized CGT therapy is far more effective than standard supportive counseling or antidepressants alone for complicated grief.
When should I see a doctor about my grief?
If your grief is preventing you from working, maintaining relationships, or caring for yourself — or if it has not meaningfully improved after 12 months — seek an evaluation from a mental health professional or physician.
Can a death doula help with complicated grief?
Death doulas are not grief therapists and cannot treat complicated grief. However, they can provide meaningful support in the period leading up to and immediately following death — and can refer to specialized grief counselors and therapists when needed.
