Mental disorders are categorized into how many clusters?

Mental disorders are categorized into three clusters according to the Diagnostic and Statistical Manual of Mental Disorders (DSM). These clusters group various personality disorders based on similar characteristics and symptoms.

The three clusters are defined as follows:

1. Cluster A: This cluster includes disorders characterized by odd or eccentric behavior. Examples include paranoid personality disorder, schizoid personality disorder, and schizotypal personality disorder.

2. Cluster B: Disorders in this cluster are marked by dramatic, emotional, or erratic behavior. Common disorders include antisocial personality disorder, borderline personality disorder, histrionic personality disorder, and narcissistic personality disorder.

3. Cluster C: This cluster encompasses disorders that are characterized by anxious or fearful behavior. It includes avoidant personality disorder, dependent personality disorder, and obsessive-compulsive personality disorder.

Understanding the structure of these clusters aids in the diagnosis and treatment of mental health conditions, as it provides clinicians with a framework to differentiate between types of personality disorders and tailor approaches to each individual's needs.
