Personality Disorders: Understanding, Diagnosis, and Treatment
This article is general information published by the practice of Dr. Sholeh Toobaei, Specialist Psychiatrist, Dubai. It has not yet been individually reviewed by a clinician and is not a substitute for personal medical advice. Published: 1 September 2026.
Scope: This article is general information about personality disorders. It is not a diagnosis or treatment plan. If you think you or someone you know may have a personality disorder, a professional assessment can help.
Personality disorders are not "bad character"
A personality disorder is a deeply ingrained, inflexible pattern of thinking, feeling, and behaving that deviates significantly from cultural expectations, causes significant distress or impairment, and is stable over time. It is not a choice. It is not "bad character." It is a pervasive way of experiencing the world that originated as a survival strategy — often in childhood — but has become maladaptive in adult life.
The word "personality" makes it sound ordinary — "oh, they just have a strong personality." But a personality disorder is not a personality trait. It is a rigid, pervasive pattern that affects how a person relates to themselves and to everyone around them. It shows up in work, relationships, social situations, and self-care. It is not situation-specific — it is the lens through which everything is experienced.
The stigma around personality disorders is extraordinary. People with personality disorders are often described as "difficult," "manipulative," "attention-seeking," or "treatment-resistant." These labels are not just unhelpful — they are wrong. The behaviours that look like "manipulation" are usually desperate attempts to get needs met in the only ways the person knows how. The behaviours that look like "attention-seeking" are usually profound fears of abandonment or feelings of emptiness. The label "treatment-resistant" is usually applied to people whose clinicians do not have the specific training needed to treat them.
The three clusters
Personality disorders are grouped into three clusters based on similar features:
Cluster A (odd or eccentric). Paranoid personality disorder — pervasive distrust and suspicion of others, reading hidden threats into benign remarks, persistently bearing grudges. Schizoid personality disorder — detachment from social relationships, restricted emotional expression. Schizotypal personality disorder — discomfort in close relationships, cognitive distortions, eccentric behaviour.
Cluster B (dramatic, emotional, or erratic). Borderline personality disorder (BPD) — instability in relationships, self-image, and emotions; marked impulsivity; recurrent self-harm or suicidal behaviour; chronic feelings of emptiness; intense anger; stress-related paranoia or dissociative symptoms. Histrionic personality disorder — excessive emotionality and attention-seeking. Narcissistic personality disorder — grandiosity, need for admiration, lack of empathy. Antisocial personality disorder — disregard for and violation of the rights of others, failure to conform to social norms, deceitfulness, impulsivity, irritability and aggressiveness, reckless disregard for safety, lack of remorse.
Cluster C (anxious or fearful). Avoidant personality disorder — social inhibition, feelings of inadequacy, hypersensitivity to negative evaluation. Dependent personality disorder — excessive need to be taken care of, leading to submissive and clinging behaviour. Obsessive-compulsive personality disorder (OCPD) — preoccupation with orderliness, perfectionism, and mental and interpersonal control (distinct from OCD, which is an anxiety disorder).
The one most commonly encountered in clinical practice is borderline personality disorder. It affects approximately 1–2% of the general population and up to 10% of psychiatric outpatients. It is the focus of the following sections because it is the most studied, the most stigmatised, and — importantly — the one with the most evidence for effective treatment.
Borderline personality disorder in detail
BPD is characterised by five core features:
Frantic efforts to avoid real or imagined abandonment. This is not the normal fear of losing someone you love. It is an intense, overwhelming terror of abandonment that drives behaviours — calling repeatedly, showing up unannounced, agreeing to things you do not want to do, threatening self-harm — that are desperately aimed at keeping the person from leaving.
Unstable and intense relationships. The relationship alternates between idealisation ("you are the best person I have ever met, you are the only one who understands me") and devaluation ("you are terrible, you do not care about me, you are just like everyone else"). This "splitting" — seeing people as all good or all bad, with no middle ground — is one of the defining features of BPD. It is exhausting for the people around the person with BPD and deeply distressing for the person with BPD, who genuinely experiences these shifts in perspective.
Identity disturbance. An unstable self-image. The person may change careers, relationships, values, goals, or even friendships rapidly. They may have difficulty answering the question "who am I?" or "what do I want?" This is not indecisiveness. It is a fundamental lack of a stable sense of self.
Impulsivity in potentially self-damaging areas. Spending, sex, substance use, reckless driving, binge eating. These are not "bad decisions." They are attempts to regulate overwhelming emotions — behaviours that temporarily reduce emotional pain but cause significant harm.
Recurrent self-harm or suicidal behaviour. Self-harm (cutting, burning, hitting) in BPD is almost never a suicide attempt. It is a mechanism for regulating overwhelming emotions. The physical pain provides a temporary focus that distracts from the emotional pain. It is not "manipulation." It is a maladaptive coping strategy that developed because the person never learned healthier ways to regulate intense emotions.
The cause of personality disorders
Personality disorders arise from a complex interaction of temperament and environment. People with personality disorders are often born with a temperamental predisposition — high emotional reactivity, difficulty self-soothing, intense responses to stimuli. When this temperamental style meets a validating or responsive environment, it may not develop into a disorder. But when it meets an invalidating environment — one that minimises, punishes, or is inconsistent in response to the person's emotional experiences — the person learns that their internal experience is unreliable and that they cannot regulate emotions on their own.
This is not about blaming parents. It is about understanding the developmental pathways that lead to personality disorders. Some people with BPD have experienced abuse or neglect. Many have not. But virtually all have experienced an environment in which their emotional experiences were not adequately validated and supported.
Treatment — the evidence is clear
Dialectical Behaviour Therapy (DBT). Developed specifically for borderline personality disorder by Marsha Linehan, DBT is the gold standard treatment. It combines individual cognitive behavioural therapy with skills training groups. The four skill modules are: mindfulness (learning to observe and describe experiences without judgment), distress tolerance (surviving crises without making them worse), emotion regulation (understanding and modulating emotions), and interpersonal effectiveness (navigating relationships while maintaining self-respect). DBT has strong evidence for reducing self-harm, suicidal behaviour, hospitalisations, and treatment dropout in people with BPD.
Mentalisation-Based Therapy (MBT). A therapy that helps people understand their own and others' mental states — thoughts, feelings, beliefs, desires — and how these drive behaviour. People with BPD often have impaired mentalisation, particularly under stress — they misread others' intentions, assume malicious intent where none exists, and have difficulty understanding their own emotional experience. MBT improves this capacity.
Transference-Focused Psychotherapy (TFP). A psychodynamic therapy that uses the therapeutic relationship (the "transference") as the primary vehicle for change. The therapist helps the person understand how their patterns of relating — idealisation, devaluation, splitting — play out in the therapeutic relationship and, by extension, in all their relationships.
Schema Therapy. An integrative approach that combines CBT, psychodynamic, and attachment theories. It identifies "early maladaptive schemas" — deeply held negative beliefs about oneself and one's relationship to the world (e.g., "I am unlovable," "People will abandon me," "I am defective") — and works to heal them through cognitive, experiential, and behavioural techniques.
Medication. There is no medication that treats personality disorders directly. However, medications can be used to treat co-occurring conditions (depression, anxiety) or specific symptoms (impulsivity, mood lability, transient psychotic symptoms). Medication is an adjunct to psychotherapy, not a replacement.
Recovery from personality disorder
Personality disorders have a much better long-term prognosis than historically believed. Longitudinal studies show that approximately 50% of people with BPD achieve remission (no longer meeting diagnostic criteria) within 10 years, and approximately 80–85% achieve remission within 20 years. Many of those who continue to meet criteria experience significantly reduced symptoms and improved functioning.
This is not "growing out of it." It is the result of therapy, time, learning new skills, and building a life worth living. The people who recover most quickly are those who receive evidence-based treatment — not the generic "talk therapy" that is often offered but not specifically adapted for personality disorders.
The Dubai context
Personality disorder treatment in Dubai has specific considerations:
Specialist availability. DBT, MBT, TFP, and schema therapy are specialised forms of psychotherapy. Not all therapists are trained in these approaches. Finding a clinician with specific personality disorder expertise is essential — general counselling is often ineffective or even counterproductive for personality disorders and can reinforce maladaptive patterns.
Cultural considerations. In some cultures, emotional expression is discouraged, and family structures place significant expectations on individuals. These cultural factors can interact with personality disorder dynamics in complex ways. A clinician who understands both the clinical evidence and the cultural context is essential.
Family involvement. Because personality disorders fundamentally affect relationships, involving family in treatment is often important. However, in some cultural contexts, family dynamics are private, and involving family in therapy requires careful navigation.
Confidentiality. People with personality disorders often have complex relationships with boundaries and disclosure. Understanding medical confidentiality in the UAE — particularly important in a relatively small expatriate community where social and professional circles overlap — is essential.
What you can do
If you think you may have a personality disorder. Seek a professional assessment. A personality disorder diagnosis is not a life sentence. It is a description of patterns that can be changed. The people who benefit most from assessment are those who stop trying to "figure it out" on their own and let a professional help.
If someone you love has a personality disorder. Educate yourself about the condition. Learn that the behaviours — the intensity, the instability, the self-harm — are not choices and are not attempts to hurt you. They are maladaptive coping strategies developed in response to early experiences. Consider family therapy or skills training specifically designed for family members of people with personality disorders. Set boundaries — compassion does not mean accepting abuse. You can love someone and still require safe, respectful treatment in return.
When should I seek help?
If you recognise a pervasive, long-standing pattern of difficulty with relationships, self-image, emotional regulation, or impulse control that is causing distress or impairment — seek a professional assessment. Personality disorders are treatable, and the right treatment — not just any treatment, but evidence-based, specialised treatment — can fundamentally change the course of the illness.
Seek urgent help — call 999 (police) or 998 (ambulance) in the UAE, or go to the nearest emergency department — if you are having thoughts of self-harm, if you are engaging in self-harm that is severe or increasing in frequency, if you are in severe emotional distress, or if you are in any way a danger to yourself.
