1. Psychological Disorders

1.1. syndrome marked by a clinically significant disturbance in an individual’s cognition, emotion regulation, or behavior

1.1.1. Maladaptive behaviors: behaviors that interfere with normal day to day life

1.1.2. Significant disturbance definitions have varied and changed over time

1.2. Medical Model: diseases including psychological disorders have physical causes that can be diagnosed, treated, and in most cases, cured often through treatment in a hospital

1.8.4.1. Helps mental health professionals communicate about their cases

1.8.4.2. Helps patient understand their diagnosis

1.8.4.3. Helps with the course of treatment and exploring causes of various disorders for both research and patient
