Psychological disorders are classified based on their symptoms, patterns, and underlying causes. The Diagnostic and Statistical Manual of Mental Disorders (DSM) is a widely used tool to categorize and diagnose different disorders.

1. Anxiety Disorders: These disorders involve excessive and uncontrollable anxiety and fear. Examples include generalized anxiety disorder, panic disorder, and social anxiety disorder.

2. Dissociative Disorders: These disorders involve disruptions or separations in consciousness, memory, identity, or perception. Examples include dissociative identity disorder (formerly known as multiple personality disorder) and dissociative amnesia.

3. Somatoform Disorders: These disorders involve physical symptoms without any obvious physical cause. Examples include conversion disorder (where psychological stress is converted into physical symptoms) and hypochondriasis (excessive worry about having a serious medical condition).

4. Mood Disorders: These disorders involve disturbances in mood or emotional states. They can be categorized into two main types: depressive disorders (such as major depressive disorder) and bipolar disorders (characterized by episodes of both depression and mania).

5. Schizophrenia: This is a severe mental disorder characterized by disorganized thoughts, hallucinations, delusions, and social withdrawal. It affects perception, thought processes, and emotions.

6. Personality Disorders: These disorders involve enduring patterns of behavior, cognition, and inner experiences that deviate from cultural expectations. Examples include borderline personality disorder and narcissistic personality disorder.

The DSM (now in its fifth edition, DSM-5) provides a comprehensive classification system that helps mental health professionals diagnose and categorize psychological disorders. It outlines specific criteria for each disorder, which aids in accurate assessment and treatment planning. The DSM also assists in research, as it establishes a common language and framework for studying and understanding psychological disorders. It continues to evolve as new research and knowledge in the field emerge.
