Borderline personality disorder is a condition characterized by instability and impulsivity. The term originates from being on the “border” of psychosis —those with the condition seem to have a different sense of reality.
Defining Borderline Personality Disorder
Borderline Personality Disorder is one of the most studied topics in modern psychology and mental health. At its core, borderline personality disorder involves a specific cluster of experiences — cognitive, emotional, and physical — that have been consistently identified across cultures and research populations.
Psychologists define borderline personality disorder using diagnostic criteria that have been refined over decades of clinical and empirical work. The core features include recognizable patterns that distinguish borderline personality disorder from related but distinct conditions.

The roots of borderline personality disorder still aren’t fully understood. As is the case for many mental health conditions, it seems to be caused by complex interactions between one’s biology and environment. The disorder has a strong genetic component, because the condition is five times more common in people whose first-degree relatives have BPD, according to the DSM-5. The balance of activity in key brain regions—namely the prefrontal cortex and the amygdala—may be shifted in people with BPD. Life circumstances also play an important role, as BPD is more common in those who experienced ch

Getting Help for Borderline Personality Disorder
Historically borderline was thought to be nearly impossible to treat. But today experts recognize that the condition is treatable with commitment to therapy, greatly improving the lives of those with borderline. The first-line treatment for BPD is dialectical behavior therapy, which teaches patients to tolerate emotional uncertainty and distress along with coping skills to regulate their emotions and build stable relationships. Other forms of therapy can be effective as well. Cognitive behavior therapy targets distorted patterns of thought. Transference -focused psychotherapy helps patients wo
