Borderline personality disorder is a condition in which people have long-term patterns of unstable or turbulent emotions, such as feelings about themselves and others.
These inner experiences often cause them to take impulsive actions and have chaotic relationships.
People with BPD are often uncertain about their identity. As a result, their interests and values may change rapidly.
People with BPD also tend to see things in terms of extremes, such as either all good or all bad. Their views of other people may change quickly. A person who is looked up to one day may be looked down on the next day. These suddenly shifting feelings often lead to intense and unstable relationships.
Other symptoms of BPD include:
Fear of being abandoned
Feelings of emptiness and boredom
Frequent displays of inappropriate anger
Impulsiveness with money, substance abuse, sexual relationships, binge eating, or shoplifting
Intolerance of being alone
Repeated crises and acts of self-injury,
such as wrist cutting or overdosing
Like other personality disorders, BPD is diagnosed based on a psychological evaluation and the history and severity of the symptoms.
Many types of individual talk therapy, such as dialectical behavioral therapy (DBT), can successfully treat BPD. In addition, group therapy can help change self-destructive behaviors.
In some cases, medications can help level mood swings and treat depression or other disorders that may occur with this condition.
The outlook depends on how severe the condition is and whether the person is willing to accept help. With long-term talk therapy, the person will often gradually improve.
