Prolonged Grief

What is Grief (prolonged)?

Grief is a natural emotional response to loss, most often the death of a loved one, but also the end of a relationship, loss of a job, or a serious change in health. Prolonged grief disorder (PGD)—sometimes called complicated or persistent grief—describes a pattern of intense, disabling sorrow that lasts longer than typical cultural or individual expectations (usually > 12 months) and interferes with daily functioning.

According to the World Health Organization (WHO) and the American Psychiatric Association (APA), PGD is now recognized as a distinct mental‑health diagnosis in the ICD‑11 and DSM‑5‑TR. The hallmark features include persistent yearning or preoccupation with the deceased, intense emotional pain, and difficulty re‑engaging with life, despite the passage of time.

Common Causes

While any significant loss can trigger grief, certain circumstances raise the risk of the grief becoming prolonged:

• Unexpected or violent death (e.g., accident, homicide, suicide)
• Multiple simultaneous losses (e.g., death of several family members)
Pre‑existing mental‑health conditions
• Depression or anxiety disorders
• Post‑traumatic stress disorder (PTSD)
• Attachment‑related personality traits (e.g., insecure attachment)
• Limited social support or isolation
• History of unresolved grief from earlier losses
• Cultural or religious beliefs that discourage open expression of sorrow
• Chronic medical illness in the bereaved person (e.g., cancer, neurodegenerative disease) that limits coping resources

Associated Symptoms

People with prolonged grief often experience a cluster of emotional, cognitive, physical, and behavioural symptoms that persist for months or years:

• Emotional: Persistent yearning or longing for the deceased, feelings of emptiness, bitterness, guilt, or shame.
• Cognitive: Intrusive thoughts about the loss, difficulty concentrating, indecisiveness, and persistent “what‑if” scenarios.
• Physical: Fatigue, sleep disturbances (insomnia or hypersomnia), appetite changes, headaches, or unexplained aches.
• Behavioural: Withdrawal from friends/family, loss of interest in previously enjoyed activities, neglect of personal responsibilities, or avoidance of reminders of the deceased.
• Functional: Impaired work or school performance, inability to maintain relationships, or decline in self‑care.

When to See a Doctor

Grief is normal, but you should seek professional help if any of the following occur:

• Intense sorrow or yearning that persists beyond 12 months (or longer than “usual” for your culture).
• Symptoms cause significant distress or impair work, school, or family life.
• Feelings of hopelessness, worthlessness, or recurrent thoughts of self‑harm.
• Physical health deteriorates (e.g., rapid weight loss, chronic pain, uncontrolled chronic disease) because of neglect.
• Substance use increases as a way to “numb” the pain.
• Recurrent intrusive memories that seem more like trauma flashbacks than ordinary remembrance.

Early evaluation by a mental‑health professional can prevent the grief from solidifying into a chronic disorder.

Diagnosis

There is no laboratory test for prolonged grief, but clinicians use structured clinical interviews and validated questionnaires to confirm the diagnosis.

Clinical interview

• Detailed loss history (type of loss, circumstances, time since loss).
• Assessment of symptom frequency, intensity, and functional impact.
• Screening for comorbid conditions (depression, anxiety, PTSD, substance‑use disorders).

Standardized tools

• Prolonged Grief Disorder-13 (PG‑13) – 13‑item scale aligned with DSM‑5‑TR criteria.
• Inventory of Complicated Grief (ICG) – 19 items, widely used in research and clinics.
• Patient Health Questionnaire‑9 (PHQ‑9) – to rule out major depressive disorder.
• Brief anxiety screens (e.g., GAD‑7) when anxiety is suspected.

Physicians may also order basic blood work (CBC, thyroid panel, vitamin B12) to exclude medical conditions that mimic depressive or fatigue‑related symptoms.

Treatment Options

Effective management combines psychotherapy, medication (when indicated), and self‑care strategies.

Psychotherapy

• Complicated Grief Therapy (CGT) – a structured, 16‑session protocol that blends grief‑focused exposure, meaning‑making, and restorative activities. CGT has demonstrated superior outcomes compared with standard depression treatment (Shear et al., 2020).
• Cognitive‑Behavioural Therapy (CBT) – targets maladaptive thoughts (e.g., guilt, self‑blame) and encourages behavioural activation.
• Acceptance and Commitment Therapy (ACT) – helps individuals accept painful emotions while committing to values‑driven actions.
• Group grief support – peer‑led or therapist‑facilitated groups provide validation and reduce isolation.

Medication

Medication is not a first‑line treatment for PGD alone, but it may be useful when comorbid depression or anxiety is present.

• Selective serotonin reuptake inhibitors (SSRIs) such as sertraline or escitalopram.
• Serotonin‑norepinephrine reuptake inhibitors (SNRIs) for mixed anxiety‑depression.
• Short‑term use of sleep‑aid medication (e.g., trazodone) if insomnia severely interferes with daily functioning.

Medication should always be prescribed and monitored by a qualified clinician.

Home‑Based & Lifestyle Strategies

• Ritualize remembrance – Create a memorial, write letters, or maintain a photo album to give the loss a structured place in life.
• Regular physical activity – Walking, yoga, or swimming can improve mood and reduce somatic tension.
• Sleep hygiene – Consistent bedtime routine, limited caffeine, and screen‑free wind‑down.
• Balanced nutrition – Meals rich in omega‑3 fatty acids, whole grains, and fresh produce support brain health.
• Mind‑body practices – Mindfulness meditation, deep‑breathing exercises, or progressive muscle relaxation.
• Social connection – Schedule regular check‑ins with trusted friends or family; consider a “grief buddy.”
• Limit avoidance – Gently re‑expose yourself to reminders (photos, places) rather than forever avoiding them.

Prevention Tips

While loss itself cannot be avoided, certain actions can reduce the likelihood that grief becomes prolonged:

• Early support – Reach out for professional or community help within the first weeks after a loss.
• Maintain routine – Preserve daily structure (meals, sleep, work) to anchor a sense of normalcy.
• Express emotions – Journaling, art, or talking with a confidant allows feelings to be processed rather than suppressed.
• Build a support network – Cultivate relationships before loss occurs; strong networks buffer against prolonged grief.
• Educate yourself – Knowing typical grief trajectories can help you recognise when symptoms are deviating.
• Address prior unresolved grief – Therapy for earlier losses can prevent “grief stacking.”
• Limit substance use – Alcohol or drugs may temporarily dull pain but often exacerbate depressive symptoms.
• Professional screening – Primary‑care providers can use brief tools (ICG‑short form) during routine visits after a major loss.

Emergency Warning Signs

Key Take‑aways

Prolonged grief disorder is a treatable condition that sits at the intersection of normal bereavement and clinical mental illness. Recognising its signs—persistent yearning, functional impairment, and emotional pain lasting more than a year—allows timely intervention. Evidence‑based therapies, particularly Complicated Grief Therapy, offer substantial relief, while medications address co‑occurring depression or anxiety. Combining professional help with supportive self‑care, social connection, and structured remembrance can restore quality of life and help individuals re‑engage meaningfully with the world.
