Personality disorder - Symptoms 

Signs and symptoms of personality disorders 

The different types of personality disorder that might need treatment can be broadly grouped into one of three clusters, called A, B or C.

Cluster A personality disorders

A person with a cluster A personality disorder tends to have difficulty relating to others and usually shows patterns of behaviour most people would regard as odd and eccentric.

The main personality disorders in this category are listed below. 

Paranoid personality disorder

A person with a paranoid personality disorder is extremely distrustful and suspicious. Other symptoms include:

  • thinking other people are lying to them or trying to manipulate them
  • feeling they cannot really trust their friends and associates
  • worrying any confidential information shared with others will be used against them
  • thinking there are hidden meanings in remarks most would regard as innocent
  • worrying their spouse or partner is unfaithful, despite a lack of evidence

Schizoid personality disorder 

A person with a schizoid personality disorder may appear cold and detached, and avoid making close social contact with others. Other symptoms include:

  • preferring to take part in activities that do not require interaction with others
  • having little desire to form close relationships, including sexual relationships
  • being uninterested when receiving criticism or praise
  • having a limited ability to experience pleasure or joy

Schizotypal personality disorder

A person with a schizotypal personality disorder is likely to have poor social skills and delusional thoughts, and behave in unusual ways. Other symptoms include:

  • attaching undue and misguided significance to everyday events, such as thinking newspaper headlines are secret messages to them
  • believing in special powers, such as telepathy or the ability to influence other people’s emotions and actions
  • having unusual ways of speaking, such as long, rambling vague sentences or going off on a tangent
  • experiencing excessive anxiety in social situations, even if they have known a particular person or group of people a long time

Cluster B personality disorders

A person with a cluster B personality disorder struggles to relate to others. As a result, they show patterns of behaviour most would regard as dramatic, erratic and threatening or disturbing.

The main personality disorders in this category are listed below.

Antisocial personality disorder

A person with an antisocial personality disorder sees other people as vulnerable and may intimidate or bully others without remorse. They lack concern about consequences their actions may have.

Symptoms include:

  • lack of concern, regret or remorse about other people's distress
  • irresponsibility and disregard for normal social behaviour
  • difficulty in sustaining long-term relationships
  • little ability to tolerate frustration and to control their anger
  • lack of guilt, or not learning from their mistakes
  • blaming others for problems in their lives

The National Institute for Health and Clinical Excellence (NICE) has recently published guidelines on how people with antisocial personality disorders should be treated. For more information, see NICE: antisocial personality disorder (PDF, 1.71Mb).

Borderline personality disorder

A person with a borderline personality disorder is emotionally unstable, has impulses to self-harm and has very intense and unstable relationships with others.

Read more information about borderline personality disorder.

Histrionic personality disorder

A person with a histrionic personality disorder is anxious about being ignored. As a result, they feel a compulsion (overwhelming urge) to be noticed and the centre of everybody’s attention. Symptoms and behaviours include:

  • displaying excessive emotion yet appearing to lack real emotional sincerity
  • dressing provocatively and engaging in inappropriate flirting or sexually seductive behaviour
  • moving quickly from one emotional state to another
  • being self-centred and caring little about other people
  • constantly seeking reassurance and approval from other people

Symptoms and signs may co-exist with borderline and narcissistic personality disorders.

Narcissistic personality disorder

A person with a narcissistic personality disorder swings between seeing themselves as special and fearing they are worthless. They may act as if they have an inflated sense of their own importance and show an intense need for other people to look up to them.

Other symptoms include:

  • exaggerating their own achievements and abilities
  • thinking they are entitled to be treated better than other people
  • exploiting other people for their own personal gain
  • lacking empathy for other people's weaknesses 
  • looking down on people they feel are ‘beneath’ them, while feeling deeply envious of people they see as being ‘above’ them

Cluster C personality disorders

A person with a cluster C personality disorder fears personal relationships and shows patterns of anxious and fearful behaviour around other people. Others may be withdrawn and reluctant to socialise.

The main personality disorders in this category are listed below.

Avoidant personality disorder

A person with an avoidant personality disorder appears painfully shy, is socially inhibited, feels inadequate and is extremely sensitive to rejection.

Unlike people with schizoid personality disorders, they desire close relationships with others but lack the confidence and ability to form them.

Dependent personality disorder

A person with a dependent personality disorder feels they have no ability to be independent. They may show an excessive need for others to look after them and are ‘clingy’. Other symptoms include:

  • finding it difficult to make decisions without other people’s guidance
  • needing others to take responsibility over what should be their own important life choices
  • not being able to express disagreement with other people
  • finding it difficult to start new activities due to a lack of confidence
  • going to extremes to obtain support and comfort
  • feeling helpless and uncomfortable when alone
  • urgently needing to start a new relationship once a previous relationship comes to an end
  • having an unrealistic and constant fear they will be left alone to fend for themselves

Obsessive compulsive personality disorder

A person with an obsessive compulsive personality disorder is anxious about issues that seem out of control or 'messy'. They are preoccupied with orderliness and ways to control their environment and may come across to others as a ‘control freak’.

Other symptoms include:

  • having an excessive interest in lists, timetables and rules
  • being so concerned with completing a task perfectly that they have problems completing it (perfectionism)
  • being a workaholic
  • having very rigid views about issues such as morality, ethics and how a person should behave in daily life
  • hoarding items that seem to have no monetary or sentimental value
  • being unable to delegate tasks to other people
  • disliking spending money, as they think it is always better to save for a ‘rainy day’

This personality disorder differs from obsessive compulsive disorder (OCD), a related mental health condition, in several important ways:

  • People with OCD are aware their behaviour is abnormal and are anxious about it. Most people with obsessive compulsive personality disorder think their behaviour is perfectly acceptable and have no desire to change it.
  • Some people with OCD are compelled to carry out rituals, such as having to touch every second lamppost as they walk down the street. This is not usually the case with people with obsessive compulsive personality disorder.
  • People with OCD may feel compelled to make lists or organise items in their house but feel anxious about doing so. People with obsessive compulsive personality disorder find relief from anxiety when doing such tasks and may become irritated when prevented from doing so.

The idea behind clusters is to acknowledge that while there are clear indicators for PD, including genetic markers that show potential for developing a PD, the human personality is varied enough, even when confined by limited development or escape strategy, that a specific 'type' can miss details or state some that don't apply in all cases.

I've got a bit of a few. A personal map of your 'go to' thoughts and feelings worked out in therapy can help you limit the damage or even avoid going there. I often find the best thing I can do is stop. I know there is always another way, but in the heat of the moment it is hard to think of another.

It is hard to find a GP that supports PD well and places in specialist departments are usually for a fixed time. I find it hard to do the right thing for so little payoff, but life is marginly better staying outside of hospital if you can take pleasure in the little things. If you use meds to make things easier it can be harder to work out what you are doing, but as long as you have a relatively side effect free experience meds can be less distracting than life without them.

Financial hardship can add stress (often a trigger for poor choices) so get all the help you can in this difficult regime.

Hi Amy9040
I'm not a medical professional but I think that it would be a good idea for you to talk to someone from the NHS who can tell you whether the ways that you are feeling are ok or something that you might need their help with. There is no need to worry about sharing your feelings with doctors/nurses - they wont be able to use it against you or tell anyone. You sound as though, your thoughts and feelings are really worrying you and I think sharing it with a professional would really help ease your mind.

There's a little 'contact us' button on this webpage that you can use to contact an NHS professional or you could call NHS direct who I've always found to be really kind and knowledgeable.

Take care
Mel

Hello,
I have read the information above and four that a lot it was accurate to what I have been going through lately. I've been feeling a lot like if I tell anyone my views or what I really feel, they will use it against me and or tell other people. I have also seen things in the corners of my eye, like moving shapes or legs and have been hearing some minor things like buzzes.
I have been feeling very suspicious of everyone around me lately, thinking that they could or try to manipulate me or harm me. Just walking down the street I find myself doubting my friends and wondering what they really are, whether this whole thing could just be in my imagination or just actors. I haven't told anyone any of this because of the reasons above, and find myself very shut out, yet able to talk to my friends and family about normal subjects, unless they come to something about me and something that could be used against me.
I think I need to know if this is something, or just something going on that's not really anything. Its been going on for a while, so if you know anything please tell me. Thank you.
