Issues: 1. BPD is a common mental disorder (1 to 2% of general population), as severe as schizophrenia or diabetes in terms of loss of years of life (10 to 25 years). 2. Psychotherapy is the first line treatment recommended, but availability and acceptability are limited. 3. General psychiatrists express difficulties treating BPD patients. Description: Guidelines emphasize on psychotherapeutic treatment as they are the most studied and successful type of treatment. However, a large proportion of BPD patients do not have access to psychotherapy for different reasons (i.e.: this kind of treatment does not exist in their area, patient is not motivated). In this course, we will review clinically useful strategies to improve the outcome for these patients, which can be used whether the patient has access to psychotherapy or not. First, we will present ways to review diagnosis and efficient ways to offer psychoeducation to the client. Then we will consider treating clinical comorbidities such as addiction, PTSD, depressive disorder, ADHD. Furthermore, we will present the common medical disorders in this population and some tools to improve their medical management (screening, follow-up). We will highlight the potential of lifestyle medicine (improving nutrition, sleep, physical activity). We will discuss the strengths and weaknesses of psychiatric hospitalization and emergency services and offer guidelines for efficient case management. Considerations related to the usefulness of psychometric tools (screening and outcome measures) will be discussed. Lastly, we will introduce some new kinds of treatments and discuss prevention.
