Understanding Personality Disorders

Learn more about personality disorders

Each person on the planet has a unique personality that represents an accumulation of genetic and cultural influences, experiences, and traits that shape his or her outward identity and inner life. But when an individual suffers from a personality disorder, he or she will exhibit thoughts and behaviors that deviate significantly from cultural expectations, resulting in a damaging loss of healthy functioning. More than just a set of idiosyncrasies or quirks, these atypical thoughts and behaviors so severely contradict societal norms that they will negatively impact the affected individual in serious ways, and will continue to do so for long periods of time.

For the purposes of diagnosis, the American Psychological Association (APA) has divided the ten personality disorders into three main groups called clusters, which are based on descriptive similarities. While it must be remembered that there are documented limitations of this organizational method, these clusters serve to help clinicians categorize their patients’ symptoms, and include the following:

  • Cluster A: paranoid, schizoid, and schizotypal personality disorders (Individuals with these disorders often appear odd or eccentric.)
  • Cluster B: antisocial, borderline, histrionic, and narcissistic personality disorders (Individuals with these disorders often appear dramatic, emotional, or erratic.)
  • Cluster C: avoidant, dependent, and obsessive-compulsive personality disorders (These individuals often appear anxious or fearful.)

Personality disorders can limit your ability to care for yourself and others; to engage in professional, academic, and social environments; and to forge and maintain personal relationships. But while these detriments can be severe, if you are suffering from a personality disorder, there is still hope for living a balanced life. With professional treatment, you can learn to manage your symptoms.

Statistics

Statistics for personality disorders

According to the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), personality disorders, while less common than other mental illnesses, affect over 9% of the adult U.S. population. While there is limited reliable data on the overall prevalence of these conditions, the APA reports the following statistics:

  • Cluster A represents about 1.5% of all diagnosed personality disorders
  • Cluster B represents about 6.0% of all diagnosed personality disorders
  • Cluster C represents about 9.1% of all diagnosed personality disorders, suggesting a high frequency of co-occurring personality disorders from different clusters
  • Certain personality disorders (e.g., antisocial personality disorder) are diagnosed more frequently in males
  • Other personality disorders (e.g., borderline, histrionic, and dependent personality disorders) are diagnosed more frequently in females

Causes & Risk Factors

Causes and risk factors for personality disorders

Personality disorders are complex diseases that result from a combination of environmental and genetic influences. While more data must be collected and reviewed to better understand the root causes of personality disorders, researchers have identified some reliable factors that, when present, may heighten your risk for developing this type of mental illness.

  • Having a first-degree relative with a personality disorder or other serious mental illness
  • Exposure to chronic conflict and stress
  • Personal history of substance abuse/addiction
  • Being the victim of abuse
  • Suffering from childhood neglect
  • Poor attachment to primary caregivers during early development
