Defining abnormality is a complex task because behavior is heavily influenced by cultural norms and social contexts. What is considered standard in one society may be viewed as abnormal in another. To provide a standardized framework, clinicians typically rely on the or the International Classification of Diseases (ICD-11) . These manuals categorize disorders based on specific symptoms and criteria, ensuring consistency in diagnosis. Key Perspectives and Models

Understanding the origins of mental illness requires looking through several theoretical lenses:

Focuses on genetics, neurotransmitter imbalances (like serotonin or dopamine), and brain structure. Treatments often include medication or medical procedures.

This view posits that disorders are the result of learned maladaptive behaviors and distorted thinking patterns. Therapy focuses on unlearning these behaviors and restructuring thoughts.

The ultimate goal of abnormal psychology is not just to label behavior, but to understand the "why" behind it to improve lives. As our understanding of the brain and society evolves, the field continues to shift away from stigmatization and toward a more integrated, "biopsychosocial" approach to mental health.
