It's a well known fact that Brian had mental problems. Unfortunately, he came upon a Doctor who took total control of his life while keeping him drug induced. That lasted for years, until a later girl-friend was able to convince his brothers about the slick unscrupulous Doctor.
She knew it for some time, but didn't have solid evidence until Brian's housekeeper supplied physical evidence to the girlfriend. The brothers immediately corrected the situation after being in denial about the Doctor for years. Correct me if I'm wrong.

we’ve heard things like that promised for years. I’ll believe it only when she says it.
