Mental illness: Thoughts, behaviours that are unhealthy
Psychiatrists have identified 10 different personality disorders which are grouped into three categories. For each type, a diagnosis will not be made if you have only one or two of the characteristics.
You may find that you meet the criteria for several different types of personality disorders. It can also be the case that a wide range of people meets the criteria for the same disorder, despite having very different personalities and different individual experiences. They may also be difficult to differentiate from other mental illnesses like anxiety, depression and schizophrenia.
Causes of personality disorders
There’s no clear reason why some people develop a personality disorder and others don’t. Most re- searchers think that a complex mix of factors is involved, such as: the environment, early childhood and teenage experiences and genetic factors.

You may be more likely to develop personality disorder if you’ve experienced:
- An unstable family life, such as living with a parent who is an alcoholic or who struggles to manage a mental health problem;
- Little or no support from your caregiver – this may be especially hard if you experienced a traumatic event or situation;
- A lack of support or bad experiences during your school life. If you had a difficult childhood or experiences like these, you might have developed certain beliefs about how people think and how relationships work.
Our experiences growing up can affect our personality in later life.
Difficult or traumatic experiences may lead to personality disorder, such as:
- Neglect;
- Losing a parent or sudden bereavement;
- Verbal, physical or sexual abuse;
- Being involved in major incidents or accidents. Not everyone who experiences a traumatic situation will develop these problems. Some experts believe inheritance may play a part in the development of personality disorders.
