overview
Personality disorders are enduring patterns of inner experience and behavior that deviate significantly from cultural expectations, are inflexible and pervasive, begin in adolescence or early adulthood, remain stable over time, and cause distress or impairment in functioning. The DSM outlines ten specific personality disorders, grouped into three clusters based on descriptive similarities. The manual also includes alternative models to support evolving perspectives in research and clinical practice.
Personality Disorders:
-
Paranoid: Distrust and suspicion of others, interpreting motives as harmful.
-
Schizoid: Detachment from social relationships and limited emotional expression.
-
Schizotypal: Discomfort in close relationships, with unusual thoughts, perceptions, or behavior.
-
Antisocial: Disregard for others’ rights, impulsivity, and a pattern of rule-breaking or criminal behavior.
-
Borderline: Instability in relationships, self-image, and emotions, with marked impulsivity.
-
Histrionic: Excessive emotionality and attention-seeking behavior.
-
Narcissistic: Grandiosity, need for admiration, and lack of empathy.
-
Avoidant: Social inhibition, feelings of inadequacy, and hypersensitivity to criticism.
-
Dependent: Excessive need to be cared for, leading to submissive and clingy behavior.
-
Obsessive-Compulsive: Preoccupation with order, control, and perfectionism.
Clusters of Personality Disorders:
-
Cluster A (Odd or Eccentric): Paranoid, Schizoid, Schizotypal
-
Cluster B (Dramatic, Emotional, or Erratic): Antisocial, Borderline, Histrionic, Narcissistic
-
Cluster C (Anxious or Fearful): Avoidant, Dependent, Obsessive-Compulsive
Categorical vs. Dimensional Models: The DSM primarily uses a categorical model, treating personality disorders as distinct diagnoses. The dimensional approach offers a different view, suggesting that personality disorders are extreme or dysfunctional expressions of common personality traits, with no clear boundary separating them from typical behavior or from each other.
Cluster | Disorder | Core Features | Common Behaviors / Tendencies |
---|---|---|---|
A | Paranoid | Distrust and suspicion of others | Reads hidden meanings into remarks, holds grudges, questions loyalty of others |
Schizoid | Detachment from relationships and limited emotional expression | Prefers solitude, emotionally distant, appears indifferent to praise or criticism | |
Schizotypal | Discomfort with relationships, odd beliefs or behavior | Magical thinking, eccentric behavior, social anxiety tied to paranoid fears | |
B | Antisocial | Disregard for the rights of others | Deceitful, impulsive, aggressive, lacks remorse, often engages in criminal behavior |
Borderline | Instability in emotions, self-image, and relationships | Fear of abandonment, impulsivity, emotional outbursts, self-harming behavior | |
Histrionic | Excessive emotionality and attention-seeking | Dramatic, seductive, shallow emotions, seeks to be the center of attention | |
Narcissistic | Grandiosity, need for admiration, lack of empathy | Exaggerates achievements, entitled, exploitative, dismissive of others’ needs | |
C | Avoidant | Social inhibition, feelings of inadequacy, hypersensitivity to rejection | Avoids social contact unless sure of acceptance, sees self as inferior, highly self-critical |
Dependent | Need to be taken care of, submissive behavior, fear of separation | Clingy, avoids independence, urgently seeks new relationships when one ends | |
Obsessive-Compulsive | Preoccupation with order, perfectionism, and control | Rigid, stubborn, over-focused on rules, difficulty delegating, often inefficient due to perfectionism |

general personality disorder
General personality disorder refers to long-standing patterns of thinking, feeling, and behaving that differ significantly from what is typically expected within the individual’s cultural context. These patterns impact how a person understands themselves and others, manages emotions, navigates relationships, and controls impulses. For a diagnosis, the traits must be inflexible, persist across various situations, cause noticeable distress or difficulty in functioning, and begin in adolescence or early adulthood.
Criteria:
A. There is a lasting pattern of inner experience and behavior that differs greatly from cultural expectations. This pattern affects at least two of the following areas:
-
Ways of perceiving and interpreting oneself, others, and events
-
Emotional expression and regulation
-
Ability to relate to others
-
Impulse control
B. This pattern is rigid and appears across a wide range of personal and social settings.
C. The pattern causes significant distress or problems in social, work, or other important areas of life.
D. The pattern is stable over time and can be traced back to adolescence or early adulthood.
E. The pattern is not better explained by another mental disorder.
F. The pattern is not the result of substance use or a medical condition.
Cluster A personality disorders
Quick Breakdown
Cluster A personality disorders are characterized by odd or eccentric behaviors and include the following three diagnoses:
-
Paranoid Personality Disorder – Marked by pervasive distrust and suspiciousness of others.
-
Schizoid Personality Disorder – Involves detachment from social relationships and a limited range of emotional expression.
-
Schizotypal Personality Disorder – Features acute discomfort in close relationships, along with cognitive or perceptual distortions and eccentric behaviors.
Individuals with Cluster A disorders may appear socially distant, suspicious, or peculiar.
Paranoid Personality Disorder
Paranoid personality disorder is marked by a consistent pattern of mistrust and suspicion toward others. Individuals with this disorder tend to believe, without valid evidence, that others are trying to harm, deceive, or betray them. These beliefs begin in early adulthood and affect various aspects of daily life, including relationships, work, and social interactions. People with this condition often misinterpret neutral or friendly behaviors as threatening and may respond with hostility or withdrawal.
Associated Features:
-
Frequently experience conflict in relationships due to suspiciousness or aloofness
-
May appear argumentative, defensive, or cold
-
Tend to misread others’ actions as hostile or critical
-
Often rigid, critical of others, yet hypersensitive to criticism themselves
-
May be drawn to strict ideologies or groups that confirm their suspicious beliefs
-
Exhibit a need for control and struggle to trust others
-
May become involved in legal conflicts or display litigious behavior
Criteria:
A. A long-standing pattern of distrust and suspicion of others, where their motives are seen as harmful or deceptive. This pattern starts by early adulthood and shows up in various situations, as reflected by four or more of the following:
-
Believes, without sufficient evidence, that others are trying to exploit, harm, or deceive them
-
Frequently doubts the loyalty or trustworthiness of friends or colleagues
-
Hesitates to share personal information due to unwarranted fear that it will be used against them
-
Interprets harmless comments or events as threatening or insulting
-
Holds grudges and is unwilling to forgive perceived slights
-
Perceives attacks on their character or reputation that are not obvious to others and responds with anger or counterattacks
-
Suspects, without justification, that their partner is being unfaithful
B. These traits are not limited to episodes of schizophrenia, bipolar disorder, depression with psychotic features, or another psychotic disorder, and are not caused by a medical condition or substance use.
Note: If these traits appear before the onset of schizophrenia, the diagnosis should be labeled “paranoid personality disorder (premorbid).”
Case Study
Tasha, a 34-year-old woman, avoids sharing details about her life with coworkers, convinced they might use the information to harm her reputation. She often accuses her partner of infidelity despite a lack of evidence and becomes defensive or angry over minor remarks. Tasha interprets a supervisor’s neutral feedback as a personal attack and has switched jobs several times due to perceived mistreatment. Despite these patterns, she sees herself as cautious rather than mistrustful.
Schizoid Personality Disorder
Schizoid personality disorder involves a long-term pattern of emotional detachment and limited interest in forming close relationships. Individuals with this disorder often prefer solitude, show little interest in social interaction, and express a narrow range of emotions in social settings. This pattern typically begins by early adulthood and is observed across various areas of life, including friendships, work, and family connections.
Associated Features:
-
Often appear emotionally flat or unresponsive, even when provoked.
-
May seem directionless or disengaged from long-term goals.
-
Tend to respond passively to life challenges.

-
Takes limited pleasure in most, if any, activities
-
Has no close friends or confidants outside of immediate family
-

B. These characteristics are not exclusively part of schizophrenia, bipolar or depressive disorders with psychotic features, another psychotic disorder, or autism spectrum disorder, and are not the result of a medical condition.
Note: If these traits are present before the onset of schizophrenia, the diagnosis may be noted as “schizoid personality disorder (premorbid).”
Case Study
Michael, a 41-year-old computer technician, spends most of his free time reading or working on technical projects alone. He shows little interest in forming friendships and avoids social gatherings. When coworkers praise his work or offer feedback, he seems indifferent. Michael reports no interest in dating and states that he does not feel lonely. His family describes him as quiet and emotionally distant, though he maintains occasional contact with his sister.
Schizotypal Personality Disorder
Schizotypal personality disorder is defined by a long-standing pattern of social and interpersonal challenges, including deep discomfort in close relationships, along with unusual thoughts, perceptions, and behaviors. These individuals often appear eccentric and may believe in things like telepathy or other paranormal phenomena. The disorder typically begins by early adulthood and is noticeable in a variety of life situations.
Associated Features:
-
May seek help for symptoms of anxiety or depression rather than personality traits.
-
Often appear awkward, socially anxious, or suspicious in interactions.

B. These traits do not occur solely as part of schizophrenia, bipolar disorder, depression with psychotic features, another psychotic disorder, or autism spectrum disorder.
Note: If these traits appear before the onset of schizophrenia, the diagnosis may be noted as “schizotypal personality disorder (premorbid).”
Case Study
Jane, a 26-year-old retail worker, often avoids her coworkers and believes that they are secretly discussing her behind her back. She frequently wears mismatched clothing and shares unusual ideas about being able to sense future events. Maya becomes increasingly anxious during group meetings and misinterprets innocent jokes as personal attacks. Though she wishes to connect with others, she struggles to build friendships and prefers to keep to herself.

other personality disorders
In addition to the ten specific personality disorders grouped into Clusters A, B, and C, the DSM includes several additional categories for personality-related conditions. These include personality changes that are the direct result of medical conditions, as well as diagnoses used when symptoms cause significant impairment but do not match the full criteria for a specific personality disorder. These categories provide clinicians with the flexibility to capture complex or atypical presentations that still require clinical attention.
Diagnosis | When It Is Used | Key Feature | Example |
---|---|---|---|
Other Specified Personality Disorder | Symptoms cause significant distress or impairment but do not fully match any one specific disorder and the clinician specifies why | Clinician identifies the specific reason full criteria are not met | “Other specified personality disorder, mixed personality features” |
Unspecified Personality Disorder | Symptoms cause significant distress or impairment but do not meet full criteria and the clinician chooses not to specify why, or there is insufficient information | Reason for not meeting criteria is not documented | Emergency room visit without full diagnostic info |
Personality Change Due to Another Medical Condition | A significant and persistent change in personality is directly caused by a medical condition | Clear medical evidence supports the personality change | Personality change due to traumatic brain injury |
Personality Change Due to Another Medical Condition
This diagnosis is used when a noticeable and lasting change in a person’s typical personality arises as a direct result of a medical condition. The change must differ significantly from the person’s usual behavior or emotional functioning and cannot be better explained by another mental health disorder. In children, the condition may show up as a significant and persistent deviation from normal development. This change often results in disruptions to daily life, relationships, or work.
Associated Features:
-
Often described by others as “not acting like themselves.”
-
May involve mood swings, impulsivity, aggression, apathy, or paranoia.
-
Can include poor judgment, disinhibition, or emotional dullness, depending on the area of the brain affected.
-
Neurological conditions linked to this disorder include brain injury, stroke, epilepsy, tumors, and degenerative diseases.
-
Other medical causes may include HIV, thyroid or adrenal disorders, or autoimmune diseases affecting the brain.
-
Symptoms and severity often reflect the underlying medical condition.
Criteria:
A lasting personality change that stems directly from another medical condition. All of the following must be true:
A. There is a consistent change from the person’s previous personality pattern.
In children, this means a significant and long-lasting shift in development or behavior for at least one year.

Case Study
Marcus, a 47-year-old man, was described by friends and family as calm and easygoing prior to suffering a traumatic brain injury in a car accident. Over the following months, he began displaying angry outbursts, inappropriate humor, and reckless decision-making. A neurological exam confirmed damage to his frontal lobe. Marcus’s behavior significantly disrupted his relationships and job performance. He met criteria for a personality change due to the brain injury, specifically the disinhibited type.
Other Specified Personality Disorder
This diagnosis is used when a person shows clear signs of a personality disorder that significantly impacts their daily life, but the symptoms do not fully align with the criteria for any one specific personality disorder. The other specified personality disorder category allows clinicians to document the reason the presentation does not meet full diagnostic criteria by specifying it in the record (e.g., “other specified personality disorder, mixed personality features”).
Unspecified Personality Disorder
This diagnosis is used when a person displays significant traits of a personality disorder that interfere with daily functioning, but the symptoms do not meet the full criteria for any specific personality disorder. Unspecified personality disorder is applied when the clinician either does not specify why the criteria are unmet or lacks enough information to make a more detailed diagnosis.
