Personality is relatively stable and that thing we just arrange the elements cognitive, emotional and sensory-motor of our experience. A personality is abnormal if a considerable tract personological considered of clinical importance is so deviant from the statistical average of the majority of human beings. So when personality traits are rigid and maladaptive and cause significant impairment or subjective distress, they constitute a Personality Disorder (DSM-IV-TR). Even though the subjects do not feel dissatisfied with their personality traits, their behavior is so disruptive or destructive for others to cause a degree of impairment in social and / or meaningful work.
