(CNN) — How a person will be diagnosed with mental illness could look significantly different in the near future.
The American Psychiatric Association announced Wednesday that it is radically reconceptualizing the main manual that clinicians use to make a mental health diagnosis. The Diagnostic and Statistical Manual of Mental Disorders will get a new name, new voices shaping its content and a new approach that will add more layers to a diagnosis.
The hope is that it will turn what some call “psychiatry’s bible” into more of a guidebook to mental health disorders — one that’s more inclusive, dynamic and educational, so patients will receive more effective treatments.
How the DSM is used
A mental health disorder impacts an individual’s thoughts and behavior and can cause ongoing distress or impair their ability to function. Why someone has a particular mental health disorder can vary, stemming from a complicated mix of brain chemistry, genetics, life experience and a person’s environment.
Unlike with an infection, where doctors can use an objective blood test to pinpoint the bacteria or virus causing the problem, there are few simple tests to determine what kind of mental health disorder someone has.
So, psychiatrists created the Diagnostic and Statistical Manual of Mental Disorders, commonly known as the DSM, to categorize mental health disorders, create diagnostic criteria and provide descriptive text to help professionals make an appropriate diagnosis based on their observations of a patient’s symptoms.
More than half of all people will experience a psychiatric disorder in their lifetime, research shows.
Putting a label on a mental health disorder is essential so that clinicians know how to treat a patient. The DSM is also important for practical reasons, like billing and insurance purposes.
Used by more than just psychiatrists, the DSM is considered the very foundation of how mental health issues are understood. The DSM gives patients, researchers, insurance, lawyers and others a common language to identify particular mental health issues.
The current edition, DSM-5-TR, contains more than 300 distinct mental disorders such as schizophrenia, obsessive compulsive disorder and alcohol use disorder.
While APA updates the manual regularly to reflect the most up-to-date science, the last update was 2022. Over the years, the DSM has come under heavy criticism. Some argue it’s not scientific enough, others argue it’s not specific enough, or even practical.
So, to improve the manual, the APA turned to an unlikely source for inspiration: its critics.
“The critics are loud, so it’s very hard to ignore them,” joked Dr. Maria Oquendo, chair of APA’s Future DSM Strategic Committee.
Oquendo said the APA spoke with several to get a better sense of how the DSM could be improved.
“We don’t have ownership of all the best ideas, and if they’re out there, we want to hear them,” she said.
What’s changing in the DSM
One of the first things APA said it will change is the manual’s name. Going forward, DSM will stand for Diagnostic Science Manual of Mental Disorders.
When the APA first created the DSM in the 1950s, many people were institutionalized, Oquendo said. Public policy makers who funded mental institutions wanted to keep track of the number of people with particular disorders, but in an era of deinstitutionalization, numbers aren’t as important.
To create the DSM, the APA pulls together hundreds of experts from around the world who discuss definitions and treatments. There are also field trials and tests. One of the bigger changes going forward is that the APA will invite people with a lived experience of a particular diagnosis to
