How are mental disorders classified in the DSM-5?

The classification of mental disorders in the DSM-5 is fundamentally organized by diagnostic criteria, symptoms, and severity. Each disorder is detailed with specific criteria that must be met for a diagnosis, allowing clinicians to make consistent and reliable assessments. Additionally, symptoms outline the behavioral and psychological signs associated with a disorder, providing a clear framework for recognition. Severity measures are included to help differentiate between the impact of the disorder on the individual's functioning, which is essential for planning treatment and understanding prognosis. This systematic approach enables mental health professionals to utilize a standardized method for diagnosing and discussing mental health issues within the field.
