GoKawiilAmerican Psychiatric Association plans to add biomarkers to next DSM edition
The American Psychiatric Association has announced it will revise the Diagnostic and Statistical Manual of Mental Disorders, aiming to incorporate biological measures into future diagnostic criteria for the first time. A strategic subcommittee, which included the author, has been working since 2024 to determine how neurobiology and biomarkers—such as blood tests and imaging scans—could supplement or refine existing symptom-based diagnoses. The current DSM-5, published in 2013, has faced criticism for relying solely on behavioral symptoms without objective biological measures.
GoKawiil's interpretation of the reporting above, not reported fact.
For over a century, psychiatric diagnosis has depended almost entirely on clinician observation of symptoms rather than measurable biology, unlike most other medical fields. Introducing biomarkers could improve diagnostic precision, treatment matching and research validity, but the science remains preliminary, meaning any changes will likely be incremental rather than a wholesale biological overhaul.

- A subcommittee has spent since 2024 studying how to add neurobiology to diagnoses
- Biomarkers like blood and imaging tests could eventually supplement symptom-based diagnosis
