Personality Disorders: Types, Symptoms, and Treatment
Understanding a personality disorder can feel overwhelming—especially when patterns of thinking, feeling, and behavior begin to interfere with daily life, close relationships, and overall mental well-being. These complex mental health conditions often involve long-standing challenges with emotional regulation, self-identity, and interpersonal relationships, and they can affect how a person relates to their own thoughts, emotions, and the world around them.
At Alamo Behavioral Health in San Antonio, we specialize in treatment for personality disorders, offering compassionate, evidence-based care for individuals struggling with a wide range of mental disorders. Whether someone is dealing with borderline personality disorder (BPD), antisocial personality disorder, avoidant personality disorder, or other types of personality disorders, our team of experienced mental health professionals works closely with each client to develop a personalized treatment plan that supports long-term healing and stability.
Many people with personality disorders experience mood swings, impulsive behaviors, low self-esteem, or a distorted self-image, which can lead to difficulties maintaining stable relationships or functioning at work and home. In some cases, these challenges may increase the risk of self-harm or suicide attempts, especially when combined with other mental health conditions such as anxiety, depression, or addiction.
This page will guide you through what personality disorders are, the different types of personality disorders, their causes, symptoms, and the most effective approaches to treating personality disorders. If you or a loved one is struggling, know that help is available—and that with the right support, meaningful change is possible at our mental health facility in San Antonio.
What Are Personality Disorders?
Personality disorders are a group of complex mental health conditions characterized by enduring patterns of thinking, feeling, and behaving that differ significantly from cultural expectations. These patterns—often referred to as maladaptive personality traits—can disrupt a person’s daily life, making it difficult to maintain stable relationships, manage emotional regulation, or navigate work and social environments.
According to the American Psychiatric Association and its Diagnostic and Statistical Manual of Mental Disorders (DSM-5) (often called the statistical manual), personality disorders are long-standing and typically begin in adolescence or early adulthood. They can affect how individuals view themselves (self-identity, self-confidence, or distorted self-image) and how they relate to others in close relationships and broader social relationships.
At Alamo Behavioral Health, we frequently work with people diagnosed with a personality disorder who may also experience other mental health conditions such as anxiety, depression, or substance use disorders. Without the right treatment plan, these conditions can increase the risk of self-harm, impulsive behaviors, or even suicide attempts. However, with compassionate, evidence-based treatment for personality disorders, individuals can build healthier patterns, improve mental well-being, and create more fulfilling lives.
Research from national mental health organizations suggests that approximately 9–15% of adults in the United States meet the criteria for one or more personality disorders, making them more common than many people realize.[1] Early diagnosis and the right therapy help are key to long-term recovery.
What Are the Different Types of Personality Disorders?
Mental health professionals group the types of personality disorders into three main categories, often called personality disorders cluster A, B, and C. Each cluster shares common features, but each condition has its own different symptoms and behavioral patterns.
Cluster A Personality Disorders
Cluster A personality disorders—often called the “odd or eccentric” personality disorders cluster—include paranoid personality disorder, schizoid personality disorder, and schizotypal personality disorder. These mental health conditions involve patterns of social detachment, suspicion, and distorted perceptions, which can make interpersonal and close relationships difficult to maintain. Individuals may appear withdrawn, distrustful, or uncomfortable in social relationships.
The following personality disorders fall into the Cluster A category:
Paranoid Personality Disorder
Paranoid personality disorder is marked by deep distrust and suspicion of others. People with this condition often believe others intend to harm or deceive them, even without clear evidence. This can severely impact interpersonal relationships and create barriers to social relationships.
Common symptoms include:[2]
- Persistent suspicion of others’ motives
- Reluctance to confide in others
- Interpreting harmless remarks as threats
- Holding grudges or perceiving attacks on character
- Difficulty forming close relationships
Schizoid Personality Disorder
Schizoid personality disorder involves a pattern of detachment from social interactions and a limited range of emotional expression. Individuals may appear indifferent to relationships and prefer solitude.
Common symptoms include:[3]
- Lack of desire for social relationships
- Preference for solitary activities
- Limited emotional expression
- Indifference to praise or criticism
- Difficulty experiencing pleasure
Schizotypal Personality Disorder
Schizotypal personality disorder is characterized by unusual thinking patterns, eccentric behavior, and discomfort in close relationships. It may include distorted perceptions or beliefs that differ from reality.
Common symptoms include:[4]
- Odd beliefs or magical thinking
- Unusual speech or behavior
- Social anxiety and discomfort
- Suspicious or paranoid thoughts
- Difficulty forming meaningful connections
Cluster B Personality Disorders
Cluster B personality disorders are known as the “dramatic, emotional, or erratic” personality disorders cluster and include borderline personality disorder (BPD), antisocial personality disorder, histrionic personality disorder, and narcissistic personality disorder. These mental health conditions are often marked by intense mood swings, impulsive behaviors, unstable interpersonal relationships, and challenges with emotional regulation. Individuals may struggle with a distorted self-image, low self-esteem, or a lack of empathy, which can affect both daily life and close relationships.
The following personality disorders are included in the Cluster B category:
Antisocial Personality Disorder
Antisocial personality disorder involves a disregard for the rights of others and social norms. Individuals may engage in harmful or manipulative behaviors without remorse, often showing a lack of empathy.
Common symptoms include:[5]
- Repeated violation of laws or rules
- Deceitful or manipulative behavior
- Impulsive behaviors and risk-taking
- Aggression or verbal abuse
- Lack of guilt or remorse
Borderline Personality Disorder (BPD)
Borderline personality disorder (BPD) is one of the most commonly treated personality disorders and is associated with intense emotional instability, mood swings, and difficulties in relationships.

- Unstable emotions and rapid mood changes
- Fear of abandonment
- Unstable or intense relationships
- Impulsive behaviors (spending, substance use, etc.)
- Self-harm or suicide attempts

Treating personality disorders like BPD often includes dialectical behavior therapy (DBT) and mentalization-based therapy, which focus on improving emotional regulation and reducing harmful behaviors.

- Lack empathy toward others
- Difficulty handling criticism
- Exploitative relationships
Cluster C Personality Disorders
Cluster C personality disorders are known as the “anxious or fearful” personality disorders cluster and include avoidant personality disorder, dependent personality disorder, and obsessive-compulsive personality disorder. These mental health conditions are characterized by persistent anxiety, low self-esteem, and a strong fear of rejection or loss, which can make social and close relationships difficult to maintain. Individuals may rely heavily on others, avoid new situations, or struggle with perfectionism and control.
The following conditions fall into this category:
Avoidant Personality Disorder
Avoidant personality disorder is part of cluster C personality disorders and involves extreme sensitivity to rejection and feelings of inadequacy.
Common symptoms include:[9]
- Social inhibition and avoidance
- Fear of criticism or rejection

- Perfectionism that interferes with tasks
- Rigid adherence to rules
- Excessive focus on details
- Difficulty delegating tasks

What Causes Personality Disorders?
There is no single cause of personality disorders. Instead, they typically develop from a combination of biological, psychological, and environmental factors.
At Alamo Behavioral Health, we help clients understand how these influences shape their experiences and guide them toward effective treatment programs.
Key contributing factors include:
- Genetics and biology: Some individuals may have a genetic predisposition to certain mental disorders or emotional sensitivities.
- Early childhood experiences: Trauma, neglect, or unstable environments during formative years can shape long-term personality traits and coping mechanisms.
- Childhood experiences and attachment: Inconsistent caregiving can impact self-identity, trust, and interpersonal relationships.
- Cultural factors: Social expectations and cultural background may influence how symptoms develop and are expressed.
- Environmental stressors: Ongoing stress, abuse, or exposure to conflict can reinforce disruptive patterns of thinking and behavior.
These combined influences can lead to distorted perceptions, difficulty managing one’s own thoughts, and challenges forming stable relationships later in life.
The good news is that personality disorders can be effectively managed. With the right care plan, support from mental health professionals, and evidence-based approaches like talk therapy, cognitive analytic therapy, and structured interventions such as structured clinical management, individuals can build healthier coping strategies and improve their overall mental well-being.
If you or a loved one is experiencing symptoms, it’s important to seek treatment early. At Alamo Behavioral Health, our team offers compassionate, personalized treatment for personality disorders designed to help individuals in San Antonio regain control, strengthen relationships, and move toward a more balanced life.
How Common Are Personality Disorders?
Personality disorders are more common than many people realize. Research from the American Psychiatric Association and national mental health studies suggests that 9–15% of adults in the United States live with at least one personality disorder.[1] Because many people experience overlapping symptoms or are not formally diagnosed, the true number may be even higher.
Below is a general breakdown of how common each condition is among people diagnosed with personality disorders:[2,3,4,5,6,7,8,9,10,11]
- Paranoid personality disorder: up to 2–4% of the population
- Schizoid personality disorder: 1% of the population or less
- Schizotypal personality disorder: up to 3–4% of the population
- Antisocial personality disorder: up to 1–4% of the population (more common in men)
- Borderline personality disorder (BPD): about 1.5–2% of the general population, but up to 20% in clinical settings
- Histrionic personality disorder: up to 1–2% of the population
- Narcissistic personality disorder: about 0.5–1% of the population
- Avoidant personality disorder: about 2–5% of the population
- Dependent personality disorder: up to 0.5–1% of the population
- Obsessive-compulsive personality disorder: about 2–8% of the population (one of the most common types)
At Alamo Behavioral Health in San Antonio, we understand that behind every statistic is a real person navigating complex mental health conditions. Early diagnosis and the right treatment for personality disorders can make a meaningful difference in long-term outcomes.
How Are Personality Disorders Treated?
Effective treatment for personality disorders typically involves a combination of therapies, support systems, and sometimes psychiatric medicines. Our mental health professionals create individualized treatment plans based on each person’s needs, symptoms, and goals.
Talk Therapy (Psychotherapy)
Talk therapy is the foundation of most treatment programs for personality disorders. Through consistent weekly sessions, individuals work with a therapist to understand their own thoughts, behaviors, and emotional patterns. Therapy focuses on improving emotional regulation, building self-confidence, and strengthening interpersonal relationships.
Dialectical Behavior Therapy (DBT)
Dialectical behavior therapy is especially effective for borderline personality disorder (BPD). This structured approach helps individuals manage mood swings, tolerate distress, and reduce impulsive behavior such as self-harm. DBT also teaches mindfulness and communication skills that support more stable relationships.
Cognitive Analytic Therapy (CAT)
Cognitive analytic therapy helps individuals identify and change long-standing disruptive patterns in thinking and behavior. It explores how past childhood experiences and early childhood experiences influence current relationships and emotional responses, supporting healthier coping strategies.
Mentalization-Based Therapy (MBT)
Mentalization-based therapy focuses on improving a person’s ability to understand their own thoughts and the thoughts of others. This approach is particularly helpful for those who struggle with distorted perceptions or intense emotional reactions in close relationships.
Structured Clinical Management (SCM)
Structured clinical management is a practical, supportive approach often used in community settings. It combines case management, therapy, and support services to help individuals maintain stability, reduce crises, and improve overall mental well-being.
Medications
While there is no single medication that cures personality disorders, psychiatric medicines such as mood stabilizers, antidepressants, or anti-anxiety medications may be used to manage specific symptoms like mood swings, depression, or anxiety—especially when other mental health conditions are present.
At Alamo Behavioral Health in San Antonio, we emphasize a comprehensive care plan that may include multiple therapeutic approaches to ensure each individual receives the right treatment for their needs.

Accurate diagnosis is essential for creating an effective treatment plan.
3. Can someone have more than one personality disorder?
Yes, it is possible for individuals to meet the criteria for more than one personality disorder, or to have a personality disorder alongside other mental health conditions such as anxiety, depression, or substance use disorders. This is sometimes referred to as co-occurring conditions and can influence how personality disorders are treated, often requiring a more comprehensive and individualized care plan.
4. How do personality disorders affect family members and loved ones?
Personality disorders can impact not only the individual but also their family members and support system. Challenges with communication, impulsive behaviors, or unstable emotions may lead to conflict or stress in close relationships. Family education and involvement in support services can play an important role in recovery, helping loved ones better understand the condition and respond in supportive, healthy ways.
5. When should someone seek professional help?
It’s important to seek treatment when patterns of thinking or behavior begin to interfere with work, relationships, or overall quality of life. If symptoms such as low self-esteem, difficulty maintaining stable relationships, or intense emotional distress persist over time, professional support can help. Early intervention can make a meaningful difference in outcomes and help individuals move toward a healthier, more balanced life.
