Borderline Personality Disorder (BPD) is a severe mental illness marked by great difficulty regulating emotions, impulsivity, suicidality and self-harm, impairment in relationship functioning and social cognition, affecting the ability to read people and their intentions accurately. In more serious cases, it is common for individuals to have multiple psychiatric diagnoses. Fortunately, there are several effective treatments for BPD including mentalization-based therapy, an attachment-based therapeutic approach that helps the individual co-regulate emotions and restore healthy mentalizing to improve decision-making and relationship functioning. Medications can be helpful in reducing symptoms, but the front-line treatment is psychotherapy and social engagement. At Monarch, we specialize in individual and group mentalization-based therapies, including the unique Mentalization and Attachment Priming Seminar, developed by Dr. J. Christopher Fowler, Monarch’s Executive Clinical Director, and implemented both at Monarch and Houston Methodist Hospital.
