Yesterday, the board of trustees of the American Psychiatric Association (APA) approved a set of updates, revisions and changes to the reference manual used to diagnose mental disorders. The revision of the manual, called the Diagnostic and Statistical Manual of Mental Disorders and abbreviated as the DSM, is the first significant update in nearly two decades.

Disorders that will be in the new DSM-5 — but only in Section 3, a category of disorders needing further research — include: Attenuated psychosis syndrome, Internet use gaming disorder, Non-suicidal self-injury, and Suicidal behavioral disorder. Section 3 disorders generally won’t be reimbursed by insurance companies for treatment, since they are still undergoing research and revision to their criteria.

So here’s a list of the major updates…

Overall Changes to the DSM

According to the American Psychiatric Association’s statement, there are two major changes to the overall DSM — the dumping of the multiaxial system, and rearranging the chapter order of disorders. Most clinicians only paid attention to Axis I and II, so it’s no surprise the Axis system was never a big hit. The current chapter order has always been a bit of a mystery to most clinicians, so it’s good to know there’s some thought going into the new order of chapters.

Chapter order:

DSM-5’s 20 chapters will be restructured based on disorders’ apparent relatedness to one another, as reflected by similarities in disorders’ underlying vulnerabilities and symptom characteristics.

The changes will align DSM-5 with the World Health Organization’s (WHO) International Classification of Diseases, eleventh edition (ICD-11) and are expected to facilitate improved communication and common use of diagnoses across disorders within chapters.

Removal of multiaxial system:

DSM-5 will move to a nonaxial documentation of diagnosis, combining the former Axes I, II, and III, with separate notations for psychosocial and contextual factors (formerly Axis IV) and disability (formerly Axis V).

Specific Disorders

Autistic disorders will undergo a reshuffling and renaming:

“[Autism] criteria will incorporate several diagnoses from DSM-IV including autistic disorder, Asperger’s disorder, childhood disintegrative disorder and pervasive developmental disorder (not otherwise specified) into the diagnosis of autism spectrum disorder for DSM-5 to help more accurately and consistently diagnose children with autism,” according to an APA statement Saturday.

The rest of this update comes from the APA’s news release on the changes:

Binge eating disorder will be moved from DSM-IV’s Appendix B: Criteria Sets and Axes Provided for Further Study to DSM-5 Section 2. The change is intended to better represent the symptoms and behaviors of people with this condition.

This means binge eating disorder is now a real, recognized mental disorder.

Disruptive mood dysregulation disorder will be included in DSM-5 to diagnose children who exhibit persistent irritability and frequent episodes of behavior outbursts three or more times a week for more than a year.

The diagnosis is intended to address concerns about potential over-diagnosis and overtreatment of bipolar disorder in children. Will children now stop being diagnosed with bipolar disorder, which has been a recurring concern among many clinicians and researchers? We will see.

Excoriation (skin-picking) disorder is new to DSM-5 and will be included in the Obsessive-Compulsive and Related Disorders chapter.

Hoarding disorder is new to DSM-5.

Its addition to DSM is supported by extensive scientific research on this disorder. This disorder will help characterize people with persistent difficulty discarding or parting with possessions, regardless of their actual value. The behavior usually has harmful effects — emotional, physical, social, financial and even legal — for a hoarder and family members.

Pedophilic disorder criteria will remain unchanged from DSM-IV, but the disorder name will be revised from pedophilia to pedophilic disorder.

Personality disorders:

DSM-5 will maintain the categorical model and criteria for the 10 personality disorders included in DSM-IV and will include the new trait-specific methodology in a separate area of Section 3 to encourage further study how this could be used to diagnose personality disorders in clinical practice.

Posttraumatic stress disorder (PTSD) will be included in a new chapter in DSM-5 on Trauma- and Stressor-Related Disorders.

DSM-5 pays more attention to the behavioral symptoms that accompany PTSD and proposes four distinct diagnostic clusters instead of three. PTSD will also be more developmentally sensitive for children and adolescents.

Removal of bereavement exclusion:

The exclusion criterion in DSM-IV applied to people experiencing depressive symptoms lasting less than two months following the death of a loved one has been removed and replaced by several notes within the text delineating the differences between grief and depression. This reflects the recognition that bereavement is a severe psychosocial stressor that can precipitate a major depressive episode beginning soon after the loss of a loved one.

Specific learning disorder broadens the DSM-IV criteria to represent distinct disorders which interfere with the acquisition and use of one or more of the following academic skills: oral language, reading, written language, or mathematics.

Substance use disorder will combine the DSM-IV categories of substance abuse and

substance dependence. In this one overarching disorder, the criteria have not only been combined, but strengthened. Previous substance abuse criteria required only one symptom while the DSM-5’s mild substance use disorder requires two to three symptoms.

The APA board of trustees also outright rejected some new disorder ideas. The following disorders won’t appear anywhere in the new DSM-5:

Anxious depression

Hypersexual disorder

Parental alienation syndrome

Sensory processing disorder

Although clinicians are “treating” these concerns, the board of trustees felt like there wasn’t even enough research to consider putting them in Section 3 of the new DSM (disorders needing further research).

So there you have it. What do you think about these final decisions for the DSM-5?
