“…Whereas some BN sufferers appear to be quite free of major psychopathology, a sizable subgroup displays prominent disturbances of mood (Milos et al, 2003), anxiety (Kaye et al, 2004), substance abuse (Newman and Gold, 1992), and personality (Cassin & von Ranson, 2005;Steiger and Bruce, 2007), as well as comorbid adult attention-deficit/hyperactivity disorder (Surman et al, 2006).
