What is mean by personality disorder?
Personality disorders are a group of mental illnesses. They involve long-term patterns of thoughts and behaviors that are unhealthy and inflexible.
A group of mental diseases known as personality disorders (PD) are characterized by persisting, maladaptive patterns of behavior, cognition, and inner experience that are displayed in a variety of circumstances and differ from those that are normal in the person's culture. These patterns form early, are rigid, and are linked to severe suffering or incapacity. The meanings differ depending on the source and are still up for debate. The International Classification of Diseases (ICD) sixth chapter and the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) both contain official criteria for diagnosing personality disorders (DSM).
