Borderline Personality Disorder
Borderline personality disorder is a longstanding pattern of swings -- in moods, relationships, self-image, and behavior. People with borderline personality disorder have very strong emotions and often try to hurt themselves, and may have problems with 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.
Symptoms: A person with borderline personality disorder has trouble controlling his thoughts and feelings, and often has impulsive and reckless behavior. Here are the condition's main symptoms:
Mood swings usually because of stressful events or relationships
Feelings of emptiness
Problems with anger
Treatment: Lifelong treatment is necessary for people with borderline personality disorder. Treatment usually includes medication to control impulses, aggression, and mood swings. Psychotherapy can help people manage impulses and reactions to stress. Sometimes, short hospital stays are also needed to manage times of crisis.
