Personality Disorders (PD) are significant in terms of prevalence, subsequent morbidity and the challenge to a range of services presented by those with the most chaotic and disturbed behaviour. Unfortunately approximately 10% of people with a PD go on to complete suicide, while 12% of all people who complete suicide are considered to have a diagnosis of PD.
It is generally acknowledged that personality disorders are caused by a combination and interaction of genetic vulnerability and adverse early experiences, such as abuse and neglect.
