DSM-5-TR, published in 2022, is a text revision of DSM-5 rather than a wholly new edition. Most core diagnostic frameworks remain intact, but DSM-5-TR adds several diagnostic entities and codes, clarifies or refines criteria and specifiers for more than 70 disorders, modernizes terminology, and substantially updates the supporting evidence text. pmc.ncbi.nlm.nih

Overview

DSM-5 was published in 2013. DSM-5-TR was developed to incorporate evidence and clinical developments from the intervening years, while preserving the overall structure of DSM-5. Its revisions are especially relevant for students because examination questions may test what has changed, what has merely been clarified, and what remains diagnostically the same. pmc.ncbi.nlm.nih

The key changes fall into four main categories:

1. New diagnoses and clinical codes

2. Revisions to diagnostic criteria and specifiers

3. Updated, less stigmatizing terminology

4. Expanded evidence on culture, sex and gender, suicide, prevalence, risk, prognosis, and comorbidity

New Diagnoses and Codes

Prolonged Grief Disorder

The most important new diagnosis is prolonged grief disorder, placed in the chapter on trauma- and stressor-related disorders. In DSM-5, persistent complex bereavement disorder appeared only in Section III as a condition for further study. DSM-5-TR establishes prolonged grief disorder as an official diagnosis.pmc.ncbi.nlm.nih+1

The diagnosis requires the death of someone close at least:

• 12 months earlier for adults

• 6 months earlier for children and adolescents

The individual must have clinically significant, persistent yearning or longing for the deceased and/or preoccupation with the deceased, along with additional grief-related symptoms. The response must cause clinically significant distress or functional impairment and exceed expected social, cultural, or religious norms for the person’s context.

Common associated symptoms include:

• Identity disruption, such as feeling that part of oneself has died

• Disbelief about the death

• Avoidance of reminders of the death

• Intense emotional pain, including anger, bitterness, or sorrow

• Difficulty re-engaging in relationships, work, interests, or future planning

• Emotional numbness

• A sense that life is meaningless

• Intense loneliness

A high-yield distinction is that prolonged grief disorder centers on the loss and the deceased person. In major depressive disorder, depressed mood and anhedonia are more generalized and are not necessarily focused on bereavement. Both diagnoses may be assigned when full criteria for both are met. psychiatry.org

Other Diagnostic Additions

DSM-5-TR also added:

These additions improve the ability to document clinically meaningful presentations that may not fit neatly into the original DSM-5 categories.pmc.ncbi.nlm.nih+1

Criteria and Specifier Revisions

Although most DSM-5 diagnostic criteria remain unchanged, DSM-5-TR includes refinements to criteria sets or specifier definitions for more than 70 disorders. Many revisions correct ambiguity, inconsistency, or outdated wording rather than changing the fundamental diagnosis.pmc.ncbi.nlm.nih+1

Autism Spectrum Disorder

DSM-5-TR clarifies Criterion A for autism spectrum disorder. DSM-5 wording could be interpreted as requiring either one or all three social-communication deficits. DSM-5-TR makes the intended threshold explicit: all three social-communication and social-interaction deficits must be present. The restricted and repetitive behaviour threshold remains at least two of four features. pmc.ncbi.nlm.nih

Manic Episode Severity

DSM-5-TR revises severity specifiers for manic episodes. The previous “mild” specifier was inconsistent with the definition of mania, which requires marked impairment, hospitalization, or psychotic features. DSM-5-TR instead uses:

• Mild: Only the minimum symptom criteria are met

• Moderate: A substantial increase in activity or impaired judgment is present

• Severe: Almost continuous supervision is required

This revision improves internal consistency between the definition of a manic episode and the way severity is described. pmc.ncbi.nlm.nih

Adjustment Disorder Course

DSM-5-TR restores course specifiers that were unintentionally omitted from DSM-5:

• Acute: Symptoms persist for less than 6 months

• Persistent: Symptoms persist for 6 months or longer after the stressor or its consequences have ended

This is particularly relevant when distinguishing an ongoing stress response from a more persistent clinical presentation. pmc.ncbi.nlm.nih

Delirium Criterion A

DSM-5-TR updates the wording of delirium Criterion A. Rather than describing reduced awareness as “reduced orientation to the environment,” the revision states that delirium involves a disturbance in attention accompanied by reduced awareness of the environment. This avoids confusion because disorientation is already listed as a possible additional cognitive disturbance. pmc.ncbi.nlm.nih

Neurocognitive Disorder Coding

DSM-5-TR makes important updates to neurocognitive disorder terminology, coding, and specifiers. Instead of relying primarily on the broad terms “with behavioural disturbance” or “without behavioural disturbance,” it provides more specific descriptors such as:

• With agitation

• With anxiety

• With mood symptoms

• With psychotic disturbance

• With other behavioural or psychological disturbance

• Without accompanying behavioural or psychological disturbance

Severity is also more directly incorporated into coding for major neurocognitive disorders. These changes support more clinically precise documentation of behavioural and psychological symptoms associated with dementia and other neurocognitive conditions.psychiatry.org

Terminology and Equity Updates

DSM-5-TR updates terminology to reflect contemporary, person-centred, and less stigmatizing language. These changes generally do not alter the underlying diagnosis, but they matter for professional communication, documentation, and exam questions. pmc.ncbi.nlm.nih

DSM-5-TR also includes broader review of cultural, ethnoracial, sex- and gender-related considerations. The revision process incorporated review by sex and gender, culture, and suicide cross-cutting groups, as well as an Ethnoracial Equity and Inclusion Work Group. pmc.ncbi.nlm.nih

Updated Descriptive Text

One of the most extensive changes in DSM-5-TR is the revision of the explanatory text that accompanies diagnoses. More than 200 experts contributed to a multi-year review of the literature published since DSM-5. pmc.ncbi.nlm.nih

The most heavily updated sections include:

• Prevalence

• Development and course

• Risk and prognostic factors

• Culture-related diagnostic issues

• Sex- and gender-related diagnostic issues

• Association with suicidal thoughts and behaviours

• Comorbidity

For students, this means the central diagnostic criteria may look familiar, but the context used to interpret those criteria is more current. DSM-5-TR places greater emphasis on how symptoms, risk, help-seeking, diagnosis, and clinical outcomes can be shaped by developmental stage, culture, social context, discrimination, racism, sex, and gender. pmc.ncbi.nlm.nih

What Students Should Remember

The following points are especially useful for examinations and clinical learning:

• DSM-5-TR is a text revision, not DSM-6; most major diagnostic categories and core criteria from DSM-5 remain in place. pmc.ncbi.nlm.nih

• Prolonged grief disorder is the most prominent new formal diagnosis. It requires persistent, impairing grief beyond 12 months in adults or 6 months in children and adolescents.pmc.ncbi.nlm.nih+1

• Persistent complex bereavement disorder was a DSM-5 Section III condition for further study; prolonged grief disorder is now an official DSM-5-TR diagnosis. journals.lww

• Autism spectrum disorder Criterion A now clearly requires all three social-communication deficit domains. pmc.ncbi.nlm.nih

• Manic episode severity specifiers and adjustment disorder course specifiers were revised or clarified. pmc.ncbi.nlm.nih

• DSM-5-TR adds stand-alone codes for suicidal behaviour and nonsuicidal self-injury, allowing documentation independent of a psychiatric diagnosis. pmc.ncbi.nlm.nih

• Neurocognitive disorder coding and behavioural/psychological symptom specifiers became more detailed. psychiatry.org

• Terminology changes aim to improve precision, reduce stigma, and support gender-affirming, person-centred care.

Clinical Example

A 40-year-old patient presents 14 months after the death of a spouse. The patient reports daily intense longing for the spouse, avoids places associated with the spouse, feels that life has no meaning, has withdrawn from friends, and cannot return to work. The symptoms are causing significant functional impairment and are inconsistent with expected cultural grieving practices.

Under DSM-5, a clinician might have considered persistent complex bereavement disorder as a condition for further study or considered other diagnoses based on the presentation. Under DSM-5-TR, the clinician can evaluate whether the patient meets formal criteria for prolonged grief disorder, while also assessing for co-occurring major depressive disorder, posttraumatic stress disorder, substance use, and suicide risk.

DSM-5-TR should be used as a clinical classification guide informed by professional judgment, a thorough assessment, the patient’s lived context, and consideration of medical, neurological, substance-related, and psychosocial contributors.
