<unk>  is listed in the Diagnostic and Statistical Manual of Mental Disorders, although only as a symptom of other disorders such as antisocial, narcissistic, and histrionic personality disorders, not as a stand-alone diagnosis. The ICD-10 disorder Haltlose personality disorder is strongly tied to<unk> . It has been shown through lie detector tests that PF (pseudologia fantastica) patients exhibit arousal, stress, and guilt from their deception. This is different from psychopaths, who experience none of those reactions. People affected by antisocial disorder lie for external personal profit in the forms of money, sex, and power. PF is strictly internal. The difference between borderline personality disorder (BPD) and PF is that BPD patients desperately try to cope with their feeling of abandonment, mistreatment, or rejection by making empty threats of suicide or false accusations of abandonment.<unk>  liars do not feel rejected; they have high levels of self-assurance that help them lie successfully. Unlike those with histrionic personality,<unk>  liars are more verbally dramatic than sexually flamboyant. Narcissists think they have achieved perfection and are unempathetic to others. PF patients do not show these anti-social behaviors; they often lie because they think their life is not interesting enough. The only diagnosis in the current system where purposeless, internally motivated deception is listed is factitious disorder. This diagnosis deals with people who lie about having physical or psychological disorders. However, research must be done to confirm the individual does not in fact have a disorder. This may become troublesome due to the fact that medical records are sealed to the public. People with PF tend to lie about their identities and past history. Because the symptoms do not match up, the individual may go undiagnosed. They could well be diagnosed under the catch-all rubric of unspecified personality disorder (UPD) (ICD-10 code F69) or perhaps even under ICD-10 code F68.8 "Other specified disorder of adult personality and behaviour" as this defines itself as "This category should be used for coding any specified disorder of adult personality and behaviour that cannot be classified under any one of the preceding headings".
