Prolonged Grief Disorder: What the Diagnosis Means

Prolonged grief disorder is a diagnosis for a small minority of bereaved people whose grief has become persistent, intense and genuinely disabling. It is not a rule about how long you are allowed to miss somebody, and reading it that way is the most common mistake made about it.

It arrived in the DSM-5-TR in 2022, having already been in the ICD-11, and the reaction was immediate and mostly hostile. That reaction deserves taking seriously rather than dismissing, so this article covers both what the diagnosis says and why people objected.

What the criteria actually require

The core of the diagnosis is yearning, not sadness. Someone meeting criteria is preoccupied with the person who died, longing for them in a way that dominates the day, with intrusive thoughts and memories arriving unbidden.

Around that core sit further features: a sense of disbelief, feeling that part of yourself has died, intense emotional pain, difficulty re-engaging with life, emotional numbness, avoiding reminders, and a sense that life is meaningless. [prigerson-2021-pgd]

Two requirements do the real gatekeeping, and both are routinely left out of summaries. A minimum time must have passed since the death. And the symptoms must cause clinically meaningful impairment in ordinary functioning, which means they are getting in the way of work, relationships or self-care rather than simply being present and painful.

Grief that is severe, long, and not stopping you living is not this diagnosis.

The two manuals do not agree

The ICD-11 and DSM-5-TR versions differ in their timing rules, their symptom lists and how the symptoms are counted, and studies applying both sets to the same bereaved people find different rates and partly different groups of people. [pgd-2024-icd-dsm-differences]

One concrete example: difficulty accepting the loss is a criterion in the ICD-11 and not in the DSM-5-TR, despite having appeared in every earlier proposed version.

That disagreement is worth knowing before anyone applies either to you, because it means a diagnosis here is less settled than a phrase like “meets criteria” makes it sound. It is a reasonable thing to ask a clinician about directly.

How common it is, and what that number means

Reported rates among bereaved people run at roughly 5 to 7 percent depending on which criteria are applied. [pgd-2024-icd-dsm-differences]

Read that from the other end. More than nine in ten bereaved people do not meet criteria for this or any other disorder, including people whose grief is intense, disorganising, and still present years later. The existence of the diagnosis says nothing about them.

That difference is not academic. It is the reason the diagnosis was created at all.

Why it exists, and why people objected

The objection is straightforward and worth stating in its strongest form: putting grief in a diagnostic manual risks turning love into a symptom, and it hands a clinical vocabulary to anybody who was already impatient with how long somebody is taking.

The case for it is practical. Before the diagnosis existed, people whose grief had become genuinely disabling were mostly treated for depression, because that was the nearest available label. Grief-targeted treatment and depression treatment are not the same, and the mismatch meant a group of people were reliably given the wrong one. A name creates a route.

Both of those things are true at once. The safeguard against the first is that the criteria are narrow and require impairment, not that the worry was silly.

What this does not change about ordinary grief

Nothing in the criteria supports a timetable, and our guide to the stages of grief covers why the most famous timetable was never evidence in the first place.

Grief comes in waves that get further apart rather than smaller. Anniversaries, songs and smells reopen it years later, and that is not a relapse. Somebody who is functioning and still crying regularly at eighteen months is grieving, not disordered.

The signal that something else is going on is not intensity or duration on their own. It is that life has stopped moving: the same day repeating, no re-engagement with anything, the loss occupying the whole of the day rather than parts of it.

No screener on this site measures grief, and that is deliberate rather than an oversight. Pointing a bereaved person at a depression questionnaire implies bereavement is depression, which is both wrong and the exact confusion this diagnosis exists to correct. The hub lists what we do cover.

When to seek help

See a GP if grief has stopped your life moving for months rather than made it painful, if you cannot work or care for yourself, if you are drinking more to get through evenings, or if you have been avoiding every reminder to the point that your world has shrunk.

Ask for grief-focused therapy by name. Our guide to grief therapy covers what the approaches involve and how they differ from general counselling.

Go urgently if you have thoughts of harming yourself or of joining the person who died. In the UK, Samaritans is free on 116 123 at any hour, and you can text SHOUT to 85258.

How MyFreud can help

The question a clinician will ask is whether anything has shifted over months, and that is exactly what grief makes impossible to judge from inside. MyFreud gives you daily mood tracking that takes seconds, so the answer is a line on a chart rather than a guess made on a bad day.
