Personality Disorders
Mental health conditions characterized by enduring, inflexible patterns of thinking, feeling, and behaving that deviate from cultural expectations, causing significant distress or impairment in social, occupational, and other important areas of functioning.
Borderline Personality Disorder (BPD)
Borderline personality disorder is a mental health condition that affects a person's ability to regulate their emotions. People with BPD may experience periods of intense and often uncontrollable emotions following a triggering event, which can affect the way they see themselves and cause them to act impulsively, disrupting relationships in their life. BPD is one of a group of conditions called "Cluster B" personality disorders — chronic conditions that cause unstable moods and emotions, impulsive behaviors, and social dysfunction. It is the most commonly diagnosed personality disorder in clinical populations, estimated to affect about 0.7% to 2.7% of the general population, though prevalence is higher in healthcare settings — about 6% in primary care, 11% to 12% in outpatient psychiatric clinics, and 22% among psychiatric inpatients.
A person living with BPD will experience at least five of the following symptoms: intense mood swings that last hours or days, a strong fear of abandonment, a pattern of unstable and intense relationships, extreme anger or trouble controlling anger, constant feelings of emptiness, a shifting sense of self-worth, suicide attempts or acts of self-harm such as cutting, and substance abuse. Some people with BPD may not see themselves positively, may self-sabotage, may view others in extremes and quickly change their opinion of them, or may cling to others due to a strong fear of abandonment.
One of the most common misconceptions is that people with BPD are intentionally manipulative. In reality, behaviors often labeled as manipulative are typically rooted in the person's attempts to cope with intense emotional distress rather than deliberate manipulation. Similarly, many people believe that those with BPD crave attention and engage in dramatic behaviors for that purpose. In reality, these behaviors often stem from a deep-seated fear of abandonment and desperate attempts to maintain relationships, rather than a desire for attention. Another harmful myth is that BPD only affects women. In fact, men make up about 25% of all people with BPD, and this misconception may cause men to be more reluctant to seek treatment out of fear of judgment. Film and television portrayals of BPD have contributed to negative stereotypes that still exist, including unhelpful and inaccurate notions relating to behavior, relationships, and recovery prospects.
The causes of BPD are unclear, but the condition appears to result from a combination of genetic and environmental factors. Traumatic events during childhood are associated with developing BPD, including parental neglect, physical or sexual abuse, and emotional abuse. While some cases stem from childhood trauma, a diagnosis is more likely to be the result of a combination of environmental factors including attachment history, biological factors, and social factors.
Psychotherapy is the most often recommended treatment for BPD. One type — dialectical behavior therapy (DBT) — helps people living with BPD learn how to balance their emotions and logic, focusing on mindfulness, dealing with feelings that cause distress, and building effective relationships. Typical treatment also includes transference-focused psychotherapy and mentalization-based treatment. While medication can help manage some BPD symptoms such as anxiety or depression, it is not part of frontline treatment.
Talk with your healthcare provider right away if symptoms get worse or if one feels suicidal. Call or text 988 if you have thoughts of harming yourself or others. People with BPD often experience suicidal thoughts, mental images, and fantasies about self-harm. Seeking support from a crisis hotline, a close loved one, or a mental health provider is essential when these thoughts arise. More broadly, if emotional instability, fear of abandonment, or impulsive behaviors are disrupting your work, relationships, or daily life, these are signs that professional support is warranted. Starting treatment as soon as possible and continuing it for an extended period increases the chances of recovery.
Antisocial Personality Disorder (ASPD)
Antisocial personality disorder is a mental health condition that can affect the way a person thinks and interacts with others, leading them to manipulate or deceive people, exploit or take advantage of someone else for personal benefit, disregard the law or the rights of other people, and feel no remorse for their actions. ASPD affects 2% to 4% of the population and is more common in men. Modern diagnostic systems consider ASPD to include two related but not identical conditions: psychopathy, which involves calculated, manipulative behavior and a limited capacity to feel emotion, and sociopathy, which involves more impulsive and haphazard antisocial behavior with somewhat more capacity to form attachments to others.
Antisocial personality disorder usually begins before age 15 as a diagnosis of conduct disorder — a pattern of aggressive or disobedient behavior including lying, stealing, ignoring rules, or bullying others. Two behaviors that are warning signs of ASPD during childhood are setting fires and animal cruelty. In adulthood, symptoms include persistent deception, impulsivity, recklessness, aggressiveness, and consistent irresponsibility in work and financial obligations. The condition generally manifests in childhood or early adolescence, with a tendency for symptoms to peak in late adolescence and early adulthood.
A common misconception is that ASPD is the same as being a criminal. While individuals with ASPD may engage in criminal behavior, not everyone with the disorder breaks the law — many people with ASPD function in society without legal infractions, even though their interpersonal relationships may be strained. Another myth is that people with ASPD can never change. While ASPD is a challenging disorder to treat, with the right interventions and support, individuals can learn to manage their symptoms and improve their relationships. A third misconception is that ASPD, sociopathy, and psychopathy are all the same thing. Although these terms are often used interchangeably, they can denote different subsets of antisocial behavior. ASPD is a clinical diagnosis, while sociopathy and psychopathy are often considered to fall along a spectrum of antisocial behaviors.
Experts don't know for certain what causes ASPD, but genetics and other biological factors are thought to play a role — especially in psychopathy — as can growing up in a traumatic or abusive environment, especially in sociopathy. Brain defects and injuries during developmental years may also be linked to ASPD. The main causes of ASPD are generally understood to be genetic predispositions, adverse childhood experiences, and neurological factors that affect impulse control. Individuals with a family history of personality disorders or those exposed to trauma in childhood are at increased risk.
Treatment for ASPD is vexing and unsatisfying by current standards. Research suggests that treatment should include medications to target anger, irritability, and other antisocial symptoms, while psychotherapy should address interpersonal, social, and cognitive aspects of the disorder. Doctors sometimes use certain psychiatric medications like mood stabilizers or atypical antipsychotics off-label to treat symptoms like impulsive aggression and associated disorders. Because people with ASPD rarely experience internal distress about their behavior, they seldom seek help voluntarily — treatment is often initiated by legal or familial pressure.
Individuals with severe ASPD symptoms may have difficulty forming stable relationships, maintaining employment, and avoiding criminal behavior, resulting in higher rates of divorce, unemployment, homelessness, and incarceration. Seeking evaluation is important whenever persistent patterns of deception, reckless disregard for others, or difficulty maintaining relationships and employment are present. If someone with ASPD also experiences co-occurring depression, substance use, or thoughts of self-harm, those conditions require immediate attention and professional care. Significant positive changes can occur in people with ASPD, warranting both hope and professional engagement.
Narcissistic Personality Disorder (NPD)
Narcissistic personality disorder is a pervasive pattern of grandiosity, a need for admiration, a lack of empathy, and a heightened sense of self-importance. Individuals with NPD may present to others as boastful, arrogant, or unlikeable, and the pattern of behavior persists over a long period and across a variety of situations or social contexts, resulting in significant impairment in social and occupational functioning. NPD may occur in up to 5% of the U.S. population and is 50% to 75% more common in males than females.
To be diagnosed with NPD, an individual must exhibit five or more of the following by early adulthood and across multiple contexts: a grandiose sense of self-importance, preoccupation with fantasies of unlimited success or power, a belief that one is special and can only be understood by other special people, a need for excessive admiration, a sense of entitlement, exploitation of others, a lack of empathy, envy of others, and arrogant or haughty behavior. People with NPD can be easily stung by criticism or defeat and may react with disdain or anger, though social withdrawal or the false appearance of humility may also follow.
One of the most pervasive misconceptions is that NPD is simply excessive self-love. While individuals with NPD exhibit an inflated sense of self-importance, the disorder is far more complex — people with NPD often harbor deep insecurities and fragile self-esteem, masked by outward confidence. Their exaggerated self-confidence is often a facade to protect themselves from intense feelings of shame and vulnerability, meaning the outward grandiosity misrepresents the internal experience. Another misconception is that people with NPD are entirely incapable of love or forming relationships. Those with NPD may find relationships harder to maintain, but forming them is not impossible — it simply takes more work and a deep understanding of how the condition influences the relationship. A further widespread myth is that the word "narcissist" simply describes a vain person, when in fact NPD is a formal clinical diagnosis distinct from everyday self-centeredness or confidence.
Research increasingly shows that the internal experience of people with NPD includes severe self-criticism, insecurity, doubts, confusion, shame, aloneness, and fear — aspects that the formal diagnosis has historically underemphasized by focusing on external grandiosity. The causes of NPD are not fully understood, but are thought to involve a combination of genetic predisposition, early childhood experiences — including both excessive praise and emotional neglect or abuse — and temperament factors that affect emotional regulation.
Due to the very nature of the disorder, most people with NPD are reluctant to admit they have a problem and even more reluctant to seek help. When they do seek treatment, psychotherapy is the primary form, which can take place in-person or via online therapy. Mood stabilizers, antidepressants, and antipsychotic drugs are sometimes prescribed in severe cases or when NPD co-occurs with another disorder. Because there is no proven medication or therapy to treat NPD specifically, providers take an individualized approach, and establishing a trusting relationship is a key component of treatment.
People with NPD may experience extreme depression or despair when faced with challenges, failure, or rejection, and are at elevated risk for completing suicide — these episodes are less likely to be impulsive acts or calls for help. Many people with NPD do not seek help until loved ones demand it. The outlook depends on the severity of symptoms and the individual's willingness to engage with treatment. If patterns of interpersonal exploitation, entitlement, emotional outbursts when criticized, or relational difficulties are causing significant problems at work or in personal life, professional evaluation is an important step — even if the individual with NPD does not initially recognize the need.
Obsessive-Compulsive Personality Disorder (OCPD)
Obsessive-compulsive personality disorder is a psychiatric disorder marked by extreme perfectionism, orderliness, and self-control that leads to functional difficulties in life. Despite having a similar name to obsessive-compulsive disorder, the two conditions have different origins, symptoms, and treatments. The DSM-5 notes that OCPD is one of the most common personality disorders in the general population, with an estimated prevalence ranging from 1.9% to 7.8%. It is classified as a Cluster C personality disorder, grouped with conditions characterized by fearfulness and anxiety.
To merit an OCPD diagnosis, an individual must exhibit at least four of the following symptoms, which typically begin in early adulthood: preoccupation or fixation with details, rules, schedules, organization, and lists even to the extent that the prevailing point of the activity is lost; perfectionism that interferes with completion of tasks; excessive devotion to work and productivity at the expense of leisure and relationships; inflexibility about matters of ethics, morality, or values; inability to discard worn-out or worthless objects; reluctance to delegate tasks or work with others; miserliness toward self and others; and rigidity and stubbornness.
The most significant and widespread misconception about OCPD is that it is simply another name for OCD. OCD is an anxiety disorder in which a person has frequent unwanted and intrusive thoughts that cause them to perform repetitive behaviors. People with OCD are usually aware that the condition is causing their behavior and accept they need professional help. People with OCPD, by contrast, usually have little if any self-awareness of their behaviors. OCPD is not characterized by intrusive thoughts, images or urges, or repetitive behaviors performed in response to those thoughts. Instead, OCPD involves pervasive, extreme patterns of excessive perfectionism and control. People with OCD see their thoughts as distressing and sometimes irrational and wish not to have them. People with OCPD think their way is the right and best way and don't see a need to change. Another common misconception is that someone with OCPD is simply "very organized" or "hardworking" — in reality, their perfectionism actively interferes with completing tasks and sustaining relationships, rather than enhancing them.
The origin of OCPD is complex and involves genetic, environmental, and psychological factors. Research suggests that early experiences emphasizing high standards, harsh criticism, or rigid rule-following may contribute to the development of OCPD. Neurobiological differences in how the brain processes perceived errors or uncertainty are also believed to play a role, though the exact mechanisms are still being studied.
The effectiveness of treating OCPD hinges on establishing and sustaining a solid therapeutic relationship. Patients may not easily recognize the need to change behaviors they consider integral to their self-identity, posing challenges to the therapeutic alliance. However, these individuals often respond positively to logical, systematic, and rational treatment approaches. Cognitive behavioral therapy is a common treatment approach, helping people examine how their rigid patterns affect their relationships and quality of life. The prognosis of OCPD tends to favor individuals with greater insight into their condition, a willingness to seek professional help, and compliance with therapeutic interventions, which frequently leads to enhanced interpersonal relationships and improved overall quality of life.
People with OCPD tend to feel validated in their patterns of rigidity and perfectionistic rules and schedules, making them less likely to seek treatment unless their behavior begins to negatively impact those around them. Someone with OCPD is far more likely to end up in therapy because a frustrated spouse or coworker pushed them toward it, rather than seeking help on their own. Seeking evaluation is particularly warranted when perfectionism is causing projects to go unfinished, when devotion to work is crowding out all personal relationships and leisure, when others are consistently distressed by rigid rules and standards, or when the person themselves begins to feel the weight of chronic dissatisfaction or exhaustion from their own demands. If symptoms are contributing to depression, anxiety, or strained relationships, a mental health professional can help significantly.
