Treatment: Most people with bipolar disorder need lifelong treatment to keep their condition managed. This usually includes medicine -- usually mood stabilizers, and sometimes also antipsychotics or antidepressants. Therapy can also help people with bipolar disorder understand it and develop skills to handle it.
Borderline Personality Disorder
Borderline personality disorder involves a longstanding pattern of swings -- in moods, relationships, self-image, and behavior (in contrast to distinct episodes of mania or depression in people with bipolar disorder). People with borderline personality disorder can experience overly strong emotional responses to upsetting life events and often try to hurt themselves. They often have chaotic relationships with people.
People with borderline personality disorder are more likely to have other mental health problems, too. They are also more likely to have had some type of trauma as a child than people with bipolar disorder, although trauma in itself does not cause borderline personality disorder. They often also can have problems with addictions, eating disorders, body image, and anxiety.
