What is a Personality Disorder?

The term Personality Disorder is a deeply ingrained and maladaptive pattern of behaviour of a specific kind, typically apparent by the time of adolescence, causing long-term difficulties in personal relationships or in functioning in society.

People with a Personality disorder differ significantly from an average person, in terms of how they think, perceive, feel or relate to others.

If you have a Personality Disorder, you may find that your beliefs and attitudes are different from most other peoples.  Other people may find it difficult to spent time with you due to your behaviour. This can make you feel very hurt and insecure; you may end up avoiding the company of other.

What Causes a Personality Disorder?

Personality disorders are incredibly complex mental health conditions and the cause is still not fully known. It is thought that they relate to incidents or traumas in childhood such as sexual or physical abuse, accidents, sudden bereavement or difficulties in parenting including neglect. 80% of people diagnosed with a personality disorder have had a childhood trauma.

Some of our personalities are inherited, some people are born with different temperaments for example, babies vary in how sociable they are, in the intensity of their reactions, and in the length of their attention span. Some experts believe that inheritance may play a relatively big part in the development of personality disorders.

People with personality disorders often experience other mental health problems, especially depression and substance abuse.

Self Help

Many people learn to cope in their own way and just get on with things. There are some things you can do that can help these are:


GP's are not experts in personality disorders after an assessment by your GP there are a few specialists you could be referred to such as a psychologist, counselling or Community Psychiatric Nurse (CPN). This form of treatment can take up to 6 months or more depending on the severity of the condition and other existing problems.

A type of cognitive behavioural therapy called dialectical behavioural therapy (DBT) has proved successful in helping people reduce impulsive self harming behaviours, especially in Borderline personality disorder. DBT is designed to help you cope better with emotional instability, while at the same time encouraging you to behave in a more positive way.

No medication is currently licensed for the treatment of any personality disorders. However, medications maybe prescribed to teat associated problems such as depression, anxiety or psychotic symptoms. Some people with Borderline personality disorder have found mood-stabilising medication helpful.

Social workers can also help by advising on benefits, employment and also supported living if needed.


For long time it was thought that there was no treatment for personality disorders however there have been advances made over the last few years. A combination of psychological, biological and theory based treatments offer hope for many people with personality disorders.

When a suitable treatment is found that suits you and your needs a good recovery can be made and you can live a healthy happy life.
