friend bipolar disorder

How I can ask my friend about his need for help about having bipolar disorder?
I had to tell my stepfather that makes many years. The key is to catch the person in a manic mood and tell him not want to go with it. I was 16 and my stepfather I heard on the grace of God and has since then been on lithium and is leading a productive and stable. Good luck and God bless you
