For some illogical reason, perhaps as a reaction to poor clinical practice or popular movies, some mental health disorders have become viewed as benefit rather than illness. Among these is Borderline Personality Disorder, a serious psychological illness describing severe, fixed weakness of the basic ego capacities governing thinking, behavior, affect, and more, deriving from faulty developmental experiences, principally the lack of a "good-enough" parenting during the early years when basic ego capacities form. A theoretical concept, "Elements of a Borderline Psychotic Psychostructural Organization," which is far more common than BPD, is a continuum of weaknesses of one or more ego capacities and far less severe.
