What Are the Different Types of Personality Disorders?
There are ten recognized personality disorders, grouped into three clusters. This page explains what each one involves, how they differ, and where the boundaries between them sit — the reference guide, in plain language.
Personality disorders influence how a person feels, thinks, and behaves in ways that can strain relationships, daily life, and quality of life. Understanding the different types promotes empathy, helps people recognize what they are dealing with, and points toward the right kind of help.
This page is the reference guide to the ten types. If you are looking for how these conditions are treated, see our page on personality disorder treatment.
The Role of Personality
Everyone has a distinct personality. People with personality disorders show extreme, unyielding patterns of thought, emotion, and behavior that differ markedly from cultural expectations. These patterns typically surface during adolescence or early adulthood and tend to persist without treatment.
Traits such as impulsiveness, anxiety, heightened sensitivity, diminished self-worth, or emotional volatility may raise the risk. Early experiences including trauma or neglect can foster coping strategies that later become entrenched.
Not every strong personality trait indicates a disorder. The clinical threshold is reached when traits become rigid, magnified, or distorted enough to seriously hinder a person's ability to maintain relationships, adapt to challenges, and hold a stable sense of self.
What Causes Personality Disorders?
The exact origins remain unclear, but a combination of factors is believed to contribute:
- Genetic factors — heritable temperament appears to raise susceptibility, though the specific genes and their interaction with environment are not yet identified
- Environmental factors — trauma, neglect, erratic parenting, lack of validation, unstable family dynamics, and early attachment disruption can all contribute
- Psychological factors — how a person views themselves and others, entrenched self-beliefs, and difficulty regulating emotion can produce coping patterns that harden over time
The Three Clusters
The DSM-5 groups personality disorders into three clusters, each sharing patterns of behavior, thought, and emotion.
Cluster A — Odd or eccentric
Paranoid, schizoid, and schizotypal. Marked by social detachment, suspicion, or unusual thinking. Often mistaken for shyness or introversion.
Cluster B — Dramatic or erratic
Antisocial, borderline, histrionic, and narcissistic. Marked by emotional intensity, unstable relationships, and impulsivity. The most commonly discussed cluster.
Cluster C — Anxious or fearful
Avoidant, dependent, and obsessive-compulsive personality disorder. Marked by anxiety, fear of rejection, and rigid control. Frequently confused with anxiety disorders.
A note on overlap
Clusters are a descriptive convenience, not rigid categories. Many people meet criteria for more than one disorder, often within the same cluster, and features frequently blur at the edges.
The Ten Personality Disorders
Where we have a dedicated page, follow the link for a fuller explanation.
Pervasive mistrust and suspicion, with a tendency to interpret others' motives as malicious without sufficient basis. People with PPD may hold grudges, read hidden meanings into ordinary remarks, and doubt the loyalty of friends and partners. Distinct from paranoid delusions in psychotic disorders, which are fixed false beliefs rather than a pattern of interpretation.
Genuine disinterest in social connection and a limited range of emotional expression. People with schizoid PD typically prefer solitary activities, take little pleasure in close relationships including family, and appear indifferent to praise or criticism. Often confused with avoidant personality disorder — the difference is that avoidant individuals want connection and fear rejection, while schizoid individuals do not want it.
Unusual thought patterns, odd perceptual experiences, eccentric behavior, and marked social discomfort. May include magical thinking, unusual beliefs, or the sense that events carry special personal meaning. Sits on a spectrum with schizophrenia but without sustained psychosis.
Disregard for the rights of others, a pattern of deceit and manipulation, impulsivity, and limited remorse. This is the clinical diagnosis underlying the informal terms sociopath and psychopath, neither of which is a DSM-5 diagnosis. Requires evidence of conduct disorder before age 15.
Intense emotional swings, profound fear of abandonment, unstable self-image, impulsive behavior, and relationships that alternate between idealization and devaluation. Self-harm and suicidal behavior are common. Among the most treatable of the personality disorders — DBT was developed specifically for it, and long-term outcomes are considerably better than most people expect.
Persistent attention-seeking, exaggerated emotional expression, and discomfort when not the center of attention. Emotions may shift rapidly and appear shallow to observers, and relationships are often considered more intimate than they actually are.
Grandiosity, a strong sense of entitlement, need for admiration, and limited empathy. Presents in covert as well as overt forms, and in a severe variant sometimes called malignant narcissism. Not sure where you land? See our narcissism self-assessment.
Pervasive social inhibition, feelings of inadequacy, and hypersensitivity to criticism or rejection. People with avoidant PD want relationships but avoid them because the risk of humiliation feels intolerable. Overlaps considerably with social anxiety disorder, and the two frequently co-occur.
Excessive need to be cared for, leading to submissive and clinging behavior and fear of separation. Difficulty making everyday decisions without reassurance, and significant discomfort or helplessness when alone. Distinct from narcissistic dependence, which is instrumental rather than fearful.
Preoccupation with orderliness, perfectionism, and control, at the expense of flexibility and efficiency. Distinct from obsessive-compulsive disorder (OCD): OCD involves unwanted intrusive thoughts and compulsions the person recognizes as excessive, while OCPD involves traits the person generally sees as correct and reasonable.
OCPD and OCD are frequently confused, including by people who have one of them. The practical difference is insight: someone with OCD is usually distressed by their compulsions and wants them to stop, while someone with OCPD generally believes their standards are right and that others are the problem. That difference changes what treatment looks like.
Signs That May Point to a Personality Disorder
Symptoms vary widely by disorder, but several indicators can suggest one may be present:
- A self-view that shifts significantly depending on circumstances or company
- Repeated difficulty in relationships across different people and settings
- Emotional responses that feel disproportionate to the situation
- Impulsive or risky actions that follow a recognizable pattern
- An unstable sense of identity, values, or direction
- Persistent difficulty regulating emotion once activated
The distinguishing feature is pervasiveness. Everyone shows some of these occasionally. A personality disorder is diagnosed when the pattern is consistent across contexts, inflexible, long-standing, and causing genuine impairment or distress.

Take the Self-AssessmentHow Personality Disorders Are Diagnosed
Diagnosis requires a comprehensive clinical assessment, not a questionnaire. A clinician reviews history, symptom patterns, and how those patterns affect work, relationships, and daily functioning. Collateral information from family or partners is often useful, because self-report has limits — some personality disorders reduce insight into one's own behavior.
Diagnosis is generally avoided before age 18, since personality is still consolidating in adolescence and many traits resolve on their own. It also requires ruling out other explanations: mood disorders, PTSD, substance use, and neurodevelopmental conditions can all produce overlapping presentations.
Are Personality Disorders Treatable?
Yes — more treatable than commonly believed, though outcomes vary by disorder and severity. Psychotherapy is the primary route.
- Dialectical behavior therapy (DBT) — developed for borderline personality disorder, with strong evidence for emotional regulation and reducing self-harm
- Schema therapy — designed specifically for entrenched personality patterns, targeting the beliefs about self and others that formed early
- Cognitive behavioral therapy (CBT) — addresses distorted thinking and builds practical coping skills
- Group therapy — offers a space to practice social skills and receive honest feedback from peers
- Medication — does not treat the personality disorder itself, but can ease co-occurring depression, anxiety, or mood instability enough for therapy to progress
