mental illness classification systems

Mental illness classification systems organize and categorize mental health conditions based on shared features, symptoms, and behaviors. These systems, such as the Diagnostic and Statistical Manual of Mental Disorders (DSM) and the International Classification of Diseases (ICD), help clinicians diagnose, study, and treat mental health issues consistently. They provide standardized criteria to identify specific disorders like depression or anxiety, ensuring clear communication among health professionals worldwide. While they guide diagnosis, these systems also acknowledge that mental health conditions can vary widely between individuals and may evolve over time.
