Diagnostic neglect: the potential impact of losing a separate axis for personality disorder.

Both major classifications in psychiatry have now moved away from the multi-axial nosological model. This is clinically understandable as the specific categorical diagnoses, other than borderline personality disorder and personality disorder 'NOS' (not otherwise specified) were so seldom used and empirical evidence would not support the polythetic categorical system. As a consequence, those with personality disorders, frequently referred to as Axis II disorders, now have to compete with all other mental disorders for clinical attention. © The Royal College of Psychiatrists 2015.
