Personality Disorders in Teens and Young Adults
Personality disorders are a group of mental health conditions characterized by long-standing patterns of behavior, thoughts, and emotions that deviate from cultural norms and cause significant impairment in functioning.
What is a personality disorder?
A personality disorder is marked by behavioral patterns that make it difficult to understand or interact with people or situations. Personality disorders can make it difficult for people to regulate their emotions and, as a result, maintain healthy relationships.

How common are personality disorders?
According to the American Psychiatric Association, approximately 9% of adults in the U.S. have at least one personality disorder. That's close to the same number of people who have diabetes; in other words, personality disorders are fairly common.
Types of personality disorders
There are many different types of personality disorders that can impact teens and young adults. Here are some common disorders.
- Avoidant personality disorder: Extreme sensitivity or shyness, with fear of being criticized or rejected.
- Dependent personality disorder: An unhealthy focus on another individual with a fear of being abandoned.
- Emotionally unstable personality disorder (EUPD): A severe fluctuation between emotions — one of the most common types of personality disorders.
- Borderline personality disorder: This includes many characteristics of other personality disorders, including fear of abandonment and intense feelings of emotions. Many people with borderline personality disorder may have multiple suicide attempts in their past.
- Impulsive personality disorder: Tendency to enter high-risk situations in an attempt to find short-term thrills.
- Narcissistic personality disorder: Characterized by a lack of empathy for others along with an oversized sense of self-importance.
- Paranoid personality disorder: Prone to distancing from others because of constant suspicions.
- Schizoid/Schizotypal personality disorder: Extreme social anxiety and detachment, often paired with eccentric behaviors.
- Obsessive compulsive personality disorder (OCPD): An ongoing pattern of inflexible behaviors, usually surrounding orderliness or control in some way.
- Histrionic personality disorder: Using excessive emotion to remain the center of attention.
- Antisocial personality disorder (ASPD): A tendency to avoid social customs and repeatedly exploit or infringe on the rights of others.
What are symptoms of personality disorders?
While there are many different types of individual personality disorders, they can be broken down into three categories.
Cluster A personality disorders
Personality disorders involving odd thinking or behavior are considered part of Cluster A. It may be difficult for individuals to comfortably socialize with others. Paranoid, schizoid, and schizotypal personality disorders are examples of Cluster A.
Cluster B personality disorders
Cluster B personality disorders tend to involve unpredictable behaviors and over dramatic emotions. Examples include antisocial, borderline, histrionic, and narcissistic personality disorders.
Cluster C personality disorders
The personality disorders included in Cluster C revolve around fear and anxiety. Both thoughts and behavior can apply. Common Cluster C personality disorders include avoidant dependent, and obsessive-compulsive personality disorder.
What are common causes of personality disorders?
There are a number of causes that can lead to the development of personality disorders in teens and young adults. Genetics can play a large role, with some disorders being linked to a gene malfunction (particularly obsessive compulsive disorder). Childhood trauma is also a common cause of developing personality disorders. Abuse (both physical and verbal) and sexual trauma can lead to a range of anxiety-related disorders.

How are personality disorders diagnosed?
It can be difficult for an individual to self-diagnose a personality disorder, which makes it so important for parents and other close relatives to identify symptoms. Healthcare providers can also help point towards a diagnosis, although most clinicians won't diagnose a personality disorder in someone under 18 years old.
Even among mental health professionals, the details of a personality disorder can be difficult to uncover. Many patients exhibit similar symptoms of anxiety and depression, which can skew an accurate diagnosis.
What types of treatment exist for personality disorders?
A personalized treatment plan is created based on the individuals and their diagnoses. Treatment options include:
- Psychotherapy
- Dialectical behavior therapy
- Cognitive behavioral therapy
What is the prognosis for personality disorders?
It is important to diagnose and treat individuals with personality disorders in order to improve their outcomes in life. Without help, they may experience a greater chance of unemployment, divorce, abuse, substance abuse, and homelessness.
