How to distinguish between bipolar disorder and borderline personality disorder

[Guest guest]

Can anyone tell me some factual information about how to distinguish between

bipolar disorder and borderline personality disorder? Do they have the same

symptomatology or different? If different, what is different? Is borderline a

form of bipolar disorder? Vice versa?

Also, isn't narcissism prevalent in both bipolar and borderline disorders?

I'm really curious and have a family member that I think might have been

misdiagnosed by the psychiatrist. If that is true, then wouldn't it follow that

the treatment won't work because she is being treated for the wrong thing?

Doesn't the treatment plan follow the correct diagnosis?
