Borderline Personality Disorder (BPD) is a personality disorder that affects up to 5.9 percent of Americans, more than bipolar disorder and schizophrenia. Individuals with BPD have a distorted self-image and difficulty controlling emotions. The cause of BPD is believed to be a complicated mix of genetics, environment (such as a history of neglect, separation or abuse) and an imbalance of mood-regulating chemicals, including serotonin, in the brain.
While BPD can affect any one of us, it's most often diagnosed in adolescents and early adulthood, and in women more often than in men.
