What Is Complicated Grief and How Is It Treated?

Grief hurts. Deeply, persistently, sometimes in ways that make daily life difficult for months. That's normal — loss of someone central to your life is one of the most significant experiences a person can go through. But for roughly 7–10% of bereaved people, grief follows a different course: it doesn't soften over time, it remains at acute-loss intensity, and it begins to cut off the possibility of a meaningful life. That's complicated grief.

What Complicated Grief Is

Complicated grief — formally recognized in the DSM-5 (2022) as Prolonged Grief Disorder — is a distinct condition from major depression, PTSD, or normal grief, though it can co-occur with both. It is characterized by:

Persistent, intense longing for the deceased that does not diminish over time
Difficulty accepting the reality of the death
Intense emotional pain (bitterness, anger, guilt, numbness) that persists beyond 12 months
Difficulty re-engaging with life — relationships, work, personal goals, future plans
A sense that life is meaningless or empty without the deceased
Feeling that part of oneself died with the person
Avoidance of reminders (or excessive rumination on reminders) of the death

How Common Is It?

Complicated grief affects roughly 7–10% of bereaved adults overall. Rates are higher after:

Sudden or traumatic deaths (accidents, violence)
Deaths by suicide
Loss of a child at any age
Loss of a spouse, particularly in longer marriages
Deaths involving prolonged caregiving followed by a care-ending loss
Losses where the bereaved had a highly dependent relationship with the deceased
Situations where the bereaved lacks social support

Complicated Grief vs. Depression

Complicated grief and depression are distinct conditions that require different treatments — though they can co-occur. Key differences:

Depression is a pervasive mood disturbance across all areas; complicated grief is specifically organized around the loss
In complicated grief, positive emotions can occur in contexts unrelated to the loss; in major depression, positive affect is generally suppressed across contexts
Antidepressants alone are less effective for complicated grief than for depression; complicated grief responds best to specialized grief-focused psychotherapy

A skilled clinician can assess which condition (or both) is present and recommend appropriate treatment.

Treatment

The most evidence-based treatment for complicated grief is Complicated Grief Treatment (CGT), developed by Dr. Katherine Shear at Columbia University. It is a structured, manualized therapy typically delivered in 16 sessions, combining:

Information about normal vs. complicated grief and the treatment process
Motivational interviewing to identify and work toward life goals outside grief
Revisiting — a structured imaginal technique in which the person tells the story of the death in a way that gradually reduces avoidance and supports processing
Situational exposure to avoided reminders
Building positive experiences and connections in current life

Clinical trials show CGT significantly outperforms standard interpersonal therapy for prolonged grief disorder. Other evidence-based approaches include grief-focused CBT and EMDR protocols specifically designed for grief.

Finding Help

If you or someone you love may be experiencing complicated grief:

Look for a mental health professional with specific training in grief therapy — not just a general therapist, but someone who specializes in loss and bereavement
The Center for Complicated Grief at Columbia University maintains a directory of trained CGT therapists
The American Foundation for Suicide Survivors and other loss-specific organizations often maintain therapist referrals for specific types of loss
Ask your primary care physician for a referral to a grief specialist

Complicated grief is a recognized, treatable condition. It is not a personal failure, a sign of weakness, or proof that you loved someone too much. It's a psychological wound that responds well to the right treatment.

Frequently Asked Questions

How is complicated grief different from normal grief?

Normal grief, while profoundly painful, gradually evolves over time. Waves of acute pain become less frequent and less intense; the grieving person begins to re-engage with life; they can eventually experience positive emotions alongside sadness. Complicated grief (also called prolonged grief disorder or PGD, and recently recognized as a formal diagnostic category in the DSM-5) is characterized by grief that remains intensely acute beyond 12 months after the loss (6 months for children), does not follow the typical trajectory of gradual integration, and significantly impairs functioning. The person may be unable to accept the death, experience persistent yearning that doesn't diminish, feel that life has no meaning without the deceased, and find it impossible to engage in activities or relationships. It affects roughly 7–10% of bereaved adults, with higher rates after traumatic, sudden, or suicide losses.

What are the symptoms of complicated grief?

Core symptoms of prolonged grief disorder include: intense longing and yearning for the deceased that does not diminish over time; difficulty accepting the death; feeling that part of oneself has died; emotional numbness or bitterness; difficulty engaging in ongoing life (relationships, work, personal goals); feeling that the future is meaningless; intrusive thoughts or images related to the death; avoiding reminders of the person, or conversely, excessive focus on reminders. To meet diagnostic criteria, symptoms must persist beyond 12 months (6 months for children), occur daily or near-daily, cause significant distress or impairment, and not be better explained by another mental health condition. Not everyone who grieves intensely at 12 months has complicated grief — cultural context, support systems, and the nature of the loss all matter.

Can complicated grief be treated?

Yes — prolonged grief disorder responds well to specific treatments. Complicated Grief Treatment (CGT), developed by Dr. Katherine Shear at Columbia University, is the most evidence-based intervention: a structured 16-session therapy that combines elements of cognitive-behavioral therapy, motivational interviewing, and imaginal revisiting of the loss. Studies show CGT significantly outperforms standard interpersonal therapy for this condition. Other effective approaches include Grief-Focused Cognitive Behavioral Therapy and certain EMDR protocols. Antidepressants alone are less effective for complicated grief than for standard depression, though they may be helpful as an adjunct. If you suspect prolonged grief disorder, a mental health professional with specific training in grief — not just general therapy — is important.
