What Is Complicated Grief (Prolonged Grief Disorder) and How Is It Treated?

By CRYSTAL BAI

What Is Complicated Grief (Prolonged Grief Disorder) and How Is It Treated?

The short answer: Complicated grief — now clinically called Prolonged Grief Disorder (PGD) — is an intense, prolonged form of grief that significantly impairs daily functioning for more than 12 months after a loss. It affects approximately 7–10% of bereaved adults and is treatable with specialized therapy.

What Is Prolonged Grief Disorder?

In 2022, Prolonged Grief Disorder was formally added to the DSM-5-TR (the diagnostic manual used by mental health professionals). It is characterized by:

  • Intense longing or yearning for the deceased that persists beyond 12 months
  • Difficulty accepting the death
  • Feeling that life is meaningless without the person
  • Emotional numbness or bitterness
  • Difficulty engaging in activities or relationships
  • A sense of disbelief or emotional shock that doesn't diminish over time

How Is Complicated Grief Different From Normal Grief?

PrevalenceUniversal human experience~7–10% of bereaved adults

Who Is at Higher Risk?

Risk factors for Prolonged Grief Disorder include:

  • Sudden, traumatic, or violent death (accident, suicide, homicide)
  • Loss of a child
  • Loss of a spouse or life partner
  • History of depression, anxiety, or previous losses
  • Lack of social support
  • Highly dependent relationship with the deceased
  • Feeling responsible for or unable to prevent the death

How Is Prolonged Grief Disorder Treated?

Standard grief support and general psychotherapy have limited effectiveness for PGD. The evidence-based treatment is:

  • Complicated Grief Treatment (CGT): A structured 16-session protocol developed at Columbia University that combines elements of cognitive-behavioral therapy with grief-specific techniques including exposure to loss reminders and imaginal conversations with the deceased
  • Prolonged Grief Disorder Therapy (PGDT): A similar structured approach
  • Medication: Antidepressants (particularly escitalopram) may help symptoms but do not address the grief process alone
