I remember reading there were some scenes tha she had a railing out of camera shot to hold on to for balance
Had not heard that story. The story always offered up by the press was that she was diagnosed in middle age. May have been p.r. spin; she worked in an era when disclosing that sort of diagnosis at a young age would have meant the end of her career.
I had a classmate who was diagnosed a few years after we got out of high-school and died at age 50.
Life was not good for her.
