Wild mood swings. Impulsive behavior. Unstable relationships. These are just a few of the symptoms that are linked to the disorder known in the Diagnostic and Statistical Manual of Mental Disorders (DSM) as “borderline personality disorder” or in the International Statistical Classification of Diseases and Related Health Problems (ICD) as “emotionally unstable personality disorder, borderline type.” Many mental health professionals find it challenging to diagnose the disorder and even find fault with its names.To learn more about this disorder and the controversies that surround it, please join us Friday, May 31, from 1 to 2 pm ET for a Twitter chat in recognition of Borderline Personality Disorder Awareness Month. The National Institute of Mental Health (NIMH) will team up with Perry D. Hoffman, Ph.D., President and co-founder of theNational Education Alliance for Borderline Personality Disorder (NEABPD).Dr. Hoffman has several grants from the NIMH that focus on families who have a relative with BPD. She conducted a landmark study documenting the importance of family emotional involvement in a patient’s recovery. Along with co-editing several books on the topic, Dr. Hoffman is also a co-principal investigator of the five-part video series on BPD “If Only We Had Known.”
