Borderline personality disorder is regarded as difficult to treat, with therapy usually lasting for at least a year. During treatment it is important, as with the treatment of other personality disorders, that a structured and therapeutic setting is established from the onset. Client’s with borderline personality disorder are often discriminated against by mental health care professionals and regarded as “trouble-makers”. It is important that therapists takes into consideration the fact that the client’s behaviour, whilst sometimes regarded as inappropriate, is a result of their disorder. The main aim of therapy should be to provide a highly structured environment in which the client’s ability to live more independently is improved.
