Conditions not directly attributable to gross brain damage or disease, or to another psychiatric disorder, meeting the following criteria:

(a) markedly dysharmonious attitudes and behaviour, involving usually several areas of functioning, e.g. affectivity, arousal, impulse control, ways of perceiving and thinking, and style of relating to others;
(b) the abnormal behaviour pattern is enduring, of long standing, and not limited to episodes of mental illness;
(c) the abnormal behaviour pattern is pervasive and clearly maladaptive to a broad range of personal and social situations;
(d) the above manifestations always appear during childhood or adolescence and continue into adulthood;
(e) the disorder leads to considerable personal distress but this may only become apparent late in its course;
(f) the disorder is usually, but not invariably, associated with significant problems in occupational and social performance.
