About our information

We publish information to help people understand more about mental health and mental illness, and the kind of care they are entitled to.

Our information isn't a substitute for personalised medical advice from a doctor or other qualified healthcare professional. We encourage you to speak to a medical professional if you need more information or support. Please read our disclaimer.

“Six years ago I didn't have the words to explain that I was distressed or put my feelings into words, and that's been something that my treatment has given me. That means now that yes, I still get distressed. I still experience those things, but now I have the words to communicate my distress.” Ellie

The Royal College of Psychiatrists has begun a piece of work to better understand:

  • how people are affected by this diagnosis
  • the impact it can have on the quality of their care and lives
  • the harms caused by negative stereotypes, prejudice and discrimination
  • barriers to accessing healthcare and other forms of support.

Information on our website will continue to evolve in light of this work. The insights and experiences of patients, families and carers will be an important part of this.

Patients and carers have also played a key role in developing the information below. It has been written with people with a diagnosis of personality disorder and the people who know them best. This information outlines:

  • current thinking about the kinds of difficulties experienced by people who have a diagnosis of personality disorder
  • why these difficulties develop
  • the forms of support that may be available to people with this diagnosis
  • how friends and families might help someone who has personality difficulties or who has been diagnosed with personality disorder

There are many reasons why personality disorder is a controversial diagnosis. However, we want to provide information to those who have been given this diagnosis.
