Why Are Personality Disorders Are So Difficult to Treat (and What Helps)?
If you or someone you love is diagnosed with a personality disorder, then you likely know that treatment can be a difficult process – but you may not know why. Simply put, personality disorders are difficult to treat because it's hard for someone suffering from one of these disorders to separate their personality (how they interact with others, how they view the world, and how they think about themselves) from the symptoms of their mental illness. Below we cover what to know about personality disorders, answer the question of can personality disorders be cured, and take a look at why they require a dedicated, specialized framework.
Key Takeaways:
- Personality disorders are challenging to treat because symptoms are deeply woven into a person's sense of identity, making them difficult to observe objectively from the inside.
- Evidence-based therapies, particularly Dialectical Behavior Therapy (DBT) and Cognitive Behavioral Therapy (CBT), have shown meaningful results for specific personality disorders, especially BPD.
- Co-occurring conditions like anxiety, depression, and PTSD are common alongside personality disorders and must be addressed as part of any effective treatment plan.
- Factors such as brain chemistry, childhood trauma, and sensory sensitivity all influence how personality disorders develop and how treatment progresses.
- A whole-person treatment philosophy — one that integrates therapy, medication management when appropriate, and lifestyle support — tends to produce better outcomes than a single-modality approach.
- Treatment resistance is common but not permanent; finding the right therapeutic match and maintaining consistency over time are among the strongest predictors of progress.
What to Know about Treating Personality Disorders
First, let's take a look at what personality disorders truly are, as a proper diagnosis is vital to ensuring the most accurate, effective treatment.
The American Psychological Association (APA) defines personality disorders as enduring patterns of inner experience and behavior that deviate markedly from cultural expectations: patterns that are pervasive, inflexible, and linked to significant distress or impairment. A thorough psychological evaluation is the starting point for any treatment plan.
"Personality disorder" is an umbrella term for a range of mental illnesses, each with distinct symptom profiles and treatment considerations, which include:
Antisocial Personality Disorder
A personality disorder that presents with a persistent disregard for laws and social norms, and failure to comply with those social customs. Other symptoms include reckless behavior, lack of remorse, deceitfulness, and consistent irresponsibility.
Avoidant Personality Disorder
A mental health disorder characterized by feelings of inadequacy, fear of rejection and risk taking, extreme shyness, high sensitivity to rejection or criticism, and avoidance in relationships or social settings.
Borderline Personality Disorder (BPD)
A personality disorder known to cause impulsive behavior and emotional instability, often leading to long-term damage to self-image and relationships. Key symptoms include a fear of abandonment, self-harming behavior, and chronic feelings of emptiness.
Obsessive-Compulsive Personality Disorder
A disorder identified by an excessive need for perfectionism, order, and control, as well as emotional and work-focused rigidity. OCPD differs from OCD in that individuals with OCPD believe their behaviors to be “right” despite how it may affect relationships, situations, or career life.
Schizoid Personality Disorder
A personality disorder characterized by a lack of social, relational/romantic, and emotional interest, and as a result may appear cold or indifferent. Individuals with schizoid traits often display a restricted range of emotions and prefer a solitary life.
Any of these diagnoses will have unique symptoms that require their own approach to treatment method. To add complexity, people with personality disorders often have multiple diagnoses. For example, it's common for people with panic disorder, anxiety disorder, and depression disorder to also have a personality disorder. That's why it's not possible to treat personality disorder with a "cookie cutter" mindset. Mental health clinicians and professionals must take a committed approach to developing a personalized treatment plan for each person with a personality disorder they meet with.
Evidence-Based Therapies for Personality Disorders
While no single therapy works for every personality disorder, research has identified several evidence-based treatments that consistently produce meaningful results. Understanding these options helps people ask better questions when evaluating their care.
Dialectical Behavior Therapy (DBT)
Developed by psychologist Marsha Linehan, DBT was originally designed to treat BPD and remains the gold-standard approach for the disorder. It combines cognitive behavioral techniques with mindfulness concepts drawn from Buddhist psychology. DBT is structured around four core skill modules:
- Mindfulness — Developing awareness of thoughts and behaviors in the present moment without judgment
- Distress Tolerance — Learning to cope with painful situations without making them worse
- Emotional Regulation — Understanding and managing intense emotional responses
- Interpersonal Effectiveness — Navigating relationships while maintaining self-respect
DBT typically includes both individual therapy sessions and skills training groups, giving patients multiple practice environments. Research consistently shows it reduces self-harming behaviors, hospitalizations, and suicidal ideation in people with BPD.
Cognitive Behavioral Therapy (CBT) and Schema Therapy
For personality disorders with strong cognitive components, such as Avoidant PD or OCPD, CBT helps patients identify automatic negative thoughts and the core beliefs driving them. Through structured exercises, people learn to challenge distorted thinking patterns and replace them with more accurate, balanced perspectives. Schema therapy extends this further by targeting deep-rooted beliefs formed in childhood that continue to shape behavior and emotional responses in adulthood. It is particularly useful when standard CBT has not produced sufficient change.
Pro Tip:
When meeting a prospective therapist for the first time, ask directly: "What evidence-based treatments do you use for personality disorders, and what does that look like in practice?" A therapist who can clearly answer this question — naming specific modalities and explaining how they apply them — is more likely to provide structured, effective care.
Digging Deep Is Necessary
It can feel frustrating for people with personality disorders to go through treatment because there are so many layers influencing how these disorders impact people's lives. These layers include:
Brain Chemistry/Genetics
Some elements of a personality disorder could be due to chemical differences and imbalances in the brain and hormones. Sometimes these characteristics are inherited, which makes it more difficult for people who grew up with them to believe things could be different, particularly if someone in their family, such as a parent, has struggled without proper treatment.
Childhood Trauma
Childhood trauma can affect us in a range of ways, depending on what we're going through at any given time. We may never be "done" unpacking it, because it can come up at different stages of life for different reasons. For someone with a personality disorder, unresolved trauma can complicate treatment, particularly if not properly addressed throughout the course of care.
Thought Patterns and Core Beliefs
Many personality disorders are sustained, in part, by deeply ingrained thoughts and beliefs, often formed early in life, that shape how a person interprets experiences and relationships. These cognitive patterns can be difficult to recognize precisely because they feel like facts rather than interpretations. For example, someone with avoidant personality disorder may hold a core belief that they are fundamentally unworthy, making it genuinely hard to accept feedback or support from a therapist without it triggering shame or withdrawal.
Addressing these beliefs is a key part of cognitive and schema-based therapies. The process involves identifying the automatic thought, examining the evidence for and against it, and gradually replacing it with a more accurate, flexible perspective — a process that takes time and repetition before it begins to feel natural.
High Sensory Sensitivity
If someone with a personality disorder is highly sensitive to changes in the environment that affect any of their five senses, it may feel more difficult for them to put what they're learning from a therapist or health coach into practice. It’s important for mental health therapists to take such sensitivities into account so that their patients successfully navigate through treatment at a pace that works best for them.
When Treatment Feels Resistant
Treatment resistance is a recognized challenge in personality disorder care. It can stem from several interconnected issues: ingrained behavioral patterns that feel ego-syntonic (meaning the person sees them as natural or justified rather than symptomatic), past negative experiences with mental health treatment, difficulty forming a trusting therapeutic alliance, or co-occurring substance use. Recognizing resistance as a clinical phenomenon, not a personal failing, helps both patients and clinicians adjust the treatment strategy rather than abandon it. Sometimes this means changing modalities, adjusting the pace of care, or addressing an untreated co-occurring condition first.
If you or someone you love is navigating a personality disorder diagnosis, our guide onhow personality disorders affect family life covers practical strategies for managing those dynamics and rebuilding connection.
Only by taking all of these layers into account can an individual be fully treated through a comprehensive mind-body approach.
A Mind-Body Framework Is Key
Because so many factors can influence how a personality disorder develops and changes, treatment must address both the physical and psychological dimensions of the disorder. Many people who have tried traditional counseling or medication by themselves may find that it didn't feel like enough, like they were still feeling physically exhausted, wired, or overwhelmed, and that they are unsure how to deal with it. Without taking into account how someone feels physically, some of the most challenging aspects of living with a personality disorder remain unaddressed. That’s why it’s so important for mental health professionals to look at the entire person, addressing physical wellbeing alongside therapeutic progress rather than treating them as separate concerns.

Frequently Asked Questions
How long does it typically take to treat a personality disorder?
There is no universal timeline. Personality disorders are enduring patterns, so treatment tends to be longer-term compared to conditions like situational depression. DBT programs, for example, are typically structured around one year, but ongoing therapy beyond that is common. Progress often follows a non-linear path. Improvement, setbacks, and periods of consolidation are all part of the process.
Can medication treat a personality disorder on its own?
No. Medication is not a standalone treatment for personality disorders. It may be used to manage specific symptoms, such as antidepressants for co-occurring depression, or mood stabilizers for emotional dysregulation, but therapy remains the primary and most evidence-supported treatment. Medication works best as a complement to psychotherapy, not a replacement.
What is the difference between a personality disorder and a mood disorder?
Mood disorders (such as major depression or bipolar disorder) primarily affect emotional states and tend to occur in episodes. Personality disorders are more pervasive; they shape how a person consistently thinks, feels, and relates to others across most areas of life and over many years. It is possible and common to have both simultaneously, which is why comprehensive evaluation matters.
Is it possible to be misdiagnosed with a personality disorder?
Yes. Certain symptoms, like emotional dysregulation, impulsivity, or social withdrawal, overlap across multiple diagnoses, including PTSD, bipolar disorder, ADHD, and autism spectrum conditions. A thorough psychological evaluation by a qualified clinician, ideally one with specific training in personality disorders, reduces the risk of misdiagnosis and ensures the treatment plan targets the right issues.
Can personality disorders improve without professional therapy?
Research suggests that personality disorders can show natural improvement over time, particularly in later adulthood, but this process is slow and inconsistent without structured support. Evidence-based therapies like DBT and CBT significantly accelerate progress and reduce the risk of harm associated with untreated symptoms. Self-help tools and supportive relationships play a role, but are not substitutes for professional care when symptoms are causing significant distress or functional impairment.
