Minister for Mental Health and Ageing Mark Butler today launched a new guide to assist health professionals to recognise and treat Borderline Personality Disorder. The Clinical Practice Guideline for the Management of Borderline Personality Disorder was developed by the National Health and Medical Research Council (NHMRC) at the Government’s request. Mr Butler said Borderline Personality Disorder (BPD) was the most serious and common of the personality disorders, affecting adolescents and adults. “Borderline Personality Disorder is estimated to affect at least one per cent of the population”, Mr Butler said. “It is associated with a high risk of suicide and causes significant loss and grief for individuals, their families and friends”.
