There are many different types of personality disorders. Clinicians and the public tend to recognize some, like Obsessive-Compulsive Personality Disorder or Paranoid Personality Disorder, more widely than others — but even the lesser-known ones deeply affect the people living with them. In every case, people with personality disorders often struggle with everyday tasks, relationships, and responsibilities. Research suggests that about 10% of the U.S. population meets the criteria for at least one personality disorder, making these among the most common psychiatric diagnoses. In fact, studies show that 60% of patients seeking mental health care have a personality disorder, and between 65% and 90% of people in addiction treatment have at least one co-occurring personality disorder.
What Is a Personality Disorder?
A personality disorder is a mental health condition marked by unhealthy patterns of thinking, feeling, and behaving. Because these patterns are often rigid and deeply ingrained, they make it difficult for a person to function in relationships, work, or daily life. People with personality disorders often believe their behavior is normal, even if it differs greatly from what society accepts. As a result, this can lead to misunderstandings and conflicts, especially when they blame others for their challenges. Over time, these dynamics can affect many areas of life, including friendships, jobs, and family relationships.
Types of Personality Disorders
Mental health professionals group personality disorders into three clusters based on shared traits. Some individuals show symptoms from more than one disorder, or even from more than one cluster.
Cluster A: Suspicious and Eccentric Behavior
These disorders involve unusual ways of thinking and interpreting the world. Cluster A includes:
- Paranoid Personality Disorder
- Schizoid Personality Disorder
- Schizotypal Personality Disorder
Cluster B: Emotional and Impulsive Behavior
People in this group often show dramatic, erratic, or overly emotional actions. Cluster B includes:
- Antisocial Personality Disorder
- Borderline Personality Disorder
- Histrionic Personality Disorder
- Narcissistic Personality Disorder
Cluster C: Anxious and Fearful Behavior
These disorders involve intense feelings of fear, anxiety, or insecurity. Cluster C includes:
- Avoidant Personality Disorder
- Dependent Personality Disorder
- Obsessive-Compulsive Personality Disorder
What Causes Personality Disorders?
The exact cause of personality disorders remains unknown. However, most experts agree that a mix of genetics, environment, trauma, and substance abuse can all play a role. Studies suggest these disorders often develop in response to difficult or painful experiences, such as childhood neglect or abuse. Importantly, people aren’t born with personality disorders — these conditions usually develop over time, especially when early symptoms go unaddressed. Without proper care, symptoms can worsen and lead to serious emotional and social struggles, which is part of why it’s also common for individuals with personality disorders to misuse alcohol or drugs as a coping mechanism.
Get Help for Personality Disorders and Addiction
If you or someone you care about is living with a personality disorder, professional help is essential, especially when a substance use issue is also present. The most effective approach treats both conditions simultaneously, an approach known as dual diagnosis treatment. Trying to treat addiction alone, without addressing the underlying mental health issue, often leads to relapse. That’s because many people with personality disorders use substances to manage their emotional pain in the first place. Fortunately, with the right care, people can learn to manage their symptoms and build a healthier, more stable life — therapy, coping skills, and consistent support all make a real difference.
