Like all personality disorders, psychotherapy is chosen to treat borderline personality disorder. However, persons diagnosed with this disorder rarely present themselves for treatment.
A supportive therapist and client-centered approach will make the therapy more effective. Rapport-building with a person who has this disorder will be much more difficult than usual because of the paranoia associated with the disorder. The therapist must be careful of raising the suspicions of the client that he or she is not trusted.
Medications are usually inappropriate for this disorder, since they can arouse unnecessary suspicion. Medications which are prescribed for specific conditions should be done so for the briefest time period possible to bring the condition under management.
Self-help groups are probably ineffective because these patients are likely to be mistrustful and suspicious of others and their motivations. Making group help might even be harmful to the patient.
