Book an AppointmentWhat Is a Personality Disorders
A personality disorder describes patterns in thinking, emotion, relationships and behaviour that are different from what's generally expected, and that cause real difficulty — in how you manage relationships, work, or everyday life. These patterns usually start showing up in the teenage years or early adulthood, and tend to run across several areas of life rather than showing up in just one situation.
Because a lot of mental health conditions share similar symptoms on the surface, working out what's actually going on takes more than a checklist. It takes a proper look at someone's history, and that's what an assessment is for.
You may benefit from a personality disorders assessment if you:
- Experience unstable relationships or frequent emotional conflicts
- Notice intense mood changes or difficulty regulating emotions
- Struggle with a persistent feeling of emptiness or emotional distress
- Experience problems with self-image, identity, or self-esteem
- Find social interactions or maintaining relationships particularly challenging
- Feel your emotional or behavioural patterns are affecting your daily life

The quick answers
What is a personality disorder assessment? It’s an unhurried conversation with a psychiatrist about how you think, feel and relate to people over time. The aim is to work out whether your experiences fit a personality disorder, or something else entirely.
How long does it take? About 45–50 minutes, in person or on a video call.
Can a psychiatrist diagnose it? Yes. A consultant psychiatrist is qualified to assess you fully and give a diagnosis when one fits.
What does it cost? £300.
Can I do it online? Yes. The online assessment is the same as the in-person one, wherever you live in the UK.
Do I need a GP referral? No, you can book directly.
When might it be worth getting assessed?
You don’t need to recognise everything below. But if several of these sound familiar and have been with you for years, it’s worth talking to a psychiatrist:
- Relationships that keep running into the same problems
- Emotions that feel intense, unpredictable or hard to manage
- A sense of who you are that shifts or feels unclear
- Patterns that keep affecting your work or your closest relationships
- A persistent feeling of emptiness
- Impulsive choices or behaviour that puts you at risk
- Difficulties that other diagnoses haven’t fully explained
Recognising yourself in this list doesn’t mean you have a personality disorder. That’s why a proper assessment matters: it looks at your whole life, not a handful of symptoms.
How is a personality disorder diagnosed?
Your history. We start by talking through what you’re struggling with now, your childhood and background, relationships, work and education, your emotional patterns, any past treatment, and your physical health.
How you cope day to day. Prof. El-Missiry looks at how you handle relationships, emotions and everyday responsibilities. He also looks at your strengths, not just the difficulties.
A structured clinical assessment. Your symptoms are explored step by step against recognised diagnostic criteria, so the outcome doesn’t rest on a quick impression.
Ruling other things in or out. Personality disorder symptoms can overlap with ADHD, bipolar disorder, PTSD, depression and anxiety. Making sure nothing else explains your experience better is part of every assessment.
Putting it together. Everything is brought into one clear picture. You get a diagnosis if one is appropriate, plus practical recommendations for what to do next.
Borderline personality disorder (BPD) and EUPD
In UK clinical practice, Borderline Personality Disorder is often called Emotionally Unstable Personality Disorder (EUPD). It usually involves difficulty managing emotions, an unsteady sense of self, and relationships that feel intense or unstable.
If your history includes painful or traumatic experiences, you’ll be supported in how much you share and when. You don’t have to go into everything at once.
One thing worth knowing: NICE, the UK’s clinical standards body, does not recommend medication as a treatment for BPD itself or its individual symptoms. Medication can still have a place when there’s a separate, co-existing condition that needs it. After your assessment, recommendations might include psychological therapy, support for related conditions, medication for a genuinely separate condition, and ongoing review with your psychiatrist.
Could it be something else?
Very possibly, and it’s the reason a symptom list online can’t give you a reliable answer. Some common overlaps:
- ADHD: impulsivity and emotional intensity show up in both.
See our ADHD assessment. - Bipolar disorder: mood shifts can look similar.
See our bipolar assessment. - PTSD: trauma responses and personality disorder symptoms can overlap a lot.
See our PTSD assessment. - Depression and anxiety: either can intensify or imitate personality disorder traits.
See our depression assessment
and anxiety assessment. - Dissociation and eating difficulties: both can sit alongside personality disorder symptoms.
See our dissociative assessment
and eating disorders pages.
A full assessment is the most reliable way to tell these apart, or to recognise when more than one is going on.

What happens after the assessment?
