A personality disorder is a mental health condition that affects how a person thinks, feels and behaves. Personality disorders can cause significant difficulties in performing day to day activities and can make relationships with others challenging.

Individuals with a personality disorder tend to experience stigma and are sometimes subject to stereotypes such as being “manipulative” or “attention-seeking”.

Labels such as these are unhelpful and don’t explain that for someone with a personality disorder they may not have the language or confidence to express how they feel and so might behave in a way that seems unusual or, in some cases, is harmful.

Causes of personality disorder

Like all mental health conditions, there is no single cause of the condition. There are two key areas that are believed to influence whether or not someone will develop a personality disorder including:

Genetics

Some personality traits are passed down through families in our DNA in the same way as the colour of our hair or eyes. In the same context as hair or eye colour, just because a parent has a personality disorder does not necessarily mean this will automatically be passed on to the child.

Childhood & Early Upbringing

Childhood is the foundation of who we become as adults and so our early experiences and upbringing is vital in moulding our personality. In cases where there is abuse, trauma, neglect, bereavement or lack of support for the child growing up, this can cause a disordered building of the child’s personality and affects how they think, feel and act.

As a result, in adulthood we tend to repeat the same disordered patterns that we have learned as a child and so this can lead to the development of a personality disorder. These often traumatic and disturbing experiences in early life are now referred to as “Adverse Childhood Experiences”.


Treatment and support for personality disorders

Treatment is dependent on how you are at the time of seeking help. A plan will be made by discussing this with a GP or psychiatrist.

Treatments may include:

There are no medications currently available that are recommended specifically to treat personality disorders; however, sometimes medication is prescribed for other reasons – an individual with a personality disorder may also have depression or severe anxiety for which an antidepressant or other types of medication might be recommended.


Self-Help Tips

As well as the supports and treatments mentioned previously, there are things you can do to take care of yourself and improve your wellbeing.

These include:

  • Keeping a journal
  • Developing a self-care box
  • Attending local support groups
  • Making time for yourself
  • Taking up a hobby
  • Developing a routine
  • Reducing drug and alcohol use
  • Trying mindfulness, relaxation or yoga
  • Eating a balanced diet
  • Exercising regularly
