Both HPD and narcissistic personality disorder (NPD) are Cluster B disorders, both involve a need for attention, and both can include exaggerated emotional expression [1, 11]. The core difference is in what kind of attention is sought and why. People with NPD seek admiration and want to be seen as superior, with grandiosity, entitlement, and limited empathy at the center of the disorder [11, 12]. People with HPD are less particular about the type of attention they receive and tend to be warmer, more emotionally responsive, and capable of empathy, though their relationships are often shallow and dependent on validation [11, 12]. The two can co-occur, and some people meet criteria for both.

Both HPD and borderline personality disorder (BPD) are Cluster B disorders, and both involve intense, shifting emotions and unstable relationships [1, 11]. The key differences are in self-image, severity, and risk. People with BPD typically experience a deeply negative self-image, chronic feelings of emptiness, intense fear of abandonment, and recurrent self-harm or suicidal behavior [11, 12]. People with HPD do not usually see themselves as bad, even though their self-esteem depends heavily on others' reactions, and self-harm and suicidal behavior are less central to the disorder [11, 12]. The two can co-occur, and a clinician familiar with personality disorders is best positioned to distinguish them.

HPD develops from an interaction of factors rather than a single cause. Family studies suggest a genetic contribution, with HPD appearing more often among first-degree relatives of people with the disorder and with other personality disorders [4, 8]. Environmental factors include inconsistent or overindulgent parenting, caregivers who modeled dramatic emotional expression, and childhood experiences in which attention was tied to appearance or performance rather than emotional connection [8, 9]. Childhood trauma, including abuse and neglect, is associated with HPD as it is with other Cluster B disorders [8, 9]. Most cases reflect a combination of biological vulnerability and developmental experiences that shape how a person learns to regulate emotion and seek connection.

No self-administered online quiz, blood test, or brain scan can diagnose HPD. Diagnosis requires a clinical evaluation by a licensed mental health professional using DSM-5-TR criteria, a detailed personal and behavioral history, and information from collateral sources when available [1, 2]. Clinicians may use structured interviews such as the Structured Clinical Interview for DSM-5 Personality Disorders, but these are administered by trained professionals and interpreted alongside the full clinical picture [1]. Online HPD quizzes can prompt useful self-reflection, but they cannot replace a professional assessment. If you recognize yourself in the symptoms, the best next step is a conversation with a qualified mental health provider.

HPD has historically been diagnosed more often in women, but newer research and the DSM-5-TR note that prevalence in men and women is similar, and that earlier figures likely reflected diagnostic bias [2, 5]. Behavioral expressions can differ. Women with HPD may show more obviously seductive presentation and attention-seeking through appearance, while men with HPD may show theatricality, exaggerated masculinity, impulsivity, or attention-seeking through bravado [2, 5]. Both presentations meet the same diagnostic criteria; the surface behavior simply takes culturally shaped forms. A clinician familiar with HPD will look past stereotypes and assess the underlying pattern.

Relationships with someone who has HPD can feel intense and rewarding at first and become exhausting over time as the need for attention recurs. Some practices that help include staying calm rather than matching the dramatic intensity of an episode, setting clear and consistent expectations rather than swinging between rescue and frustration, avoiding overpromising in the early excited phase of the relationship, and protecting your own time and energy [11]. Encouraging professional treatment is appropriate when the person is open to it, but pressuring someone into care rarely works. Family and partners often benefit from their own therapy or support to navigate the relationship without losing themselves [11].

Reach out to a licensed mental health professional for a clinical evaluation. HPD is best assessed by clinicians experienced with personality pathology, since it overlaps with several other conditions and is easily misread in both directions. If the person you are concerned about is reluctant to consider treatment, which is common with HPD, focus on the impact specific patterns are having on their relationships, work, or mood rather than on labels. Many people first engage with care to treat depression, anxiety, or relationship distress, which can open a path to broader treatment.

Yes, though treatment is challenging and requires long-term commitment. Psychotherapy is the primary treatment, with supportive therapy, psychodynamic psychotherapy, cognitive behavioral therapy, dialectical behavior therapy, and group therapy each used in clinical practice [13, 14, 15]. There is no FDA-approved medication for HPD itself; medication is used to manage co-occurring depression, anxiety, or substance use [13, 14]. Progress is usually gradual rather than rapid, and a person's engagement with treatment is the strongest predictor of meaningful change. Working with a clinician experienced in personality disorders meaningfully improves outcomes [13, 15].
