Pathological liar
From Wikipedia, the free encyclopedia
Pathological liar is a non-clinical term for a person who intentionally provides untrue accounts, often not to hide or gain anything in particular. This is different from a person who lies, yet believes them, which is known as
confabulation. Though "pathological liar" is not a clinical term, this only indicates that it is not defined in the
Diagnostic and Statistical Manual of Mental Disorders (Fourth Edition), or
DSM-IV, as a disorder. Pathological lying may be the manifestation of an
anti-social behavior, such as
Antisocial personality disorder, also known as sociopathic behavior.
It should be stated that still other disorders may include chronic lying as part of their description. For example, a person diagnosed with
Dissociative identity disorder will deny doing things he or she does not remember. The person may have no memory of an action and will insist that it never happened. However, anyone who had witnessed the action will believe the individual to be lying. This is, of course, an over-simplified version, and any actual situation will be more complicated. Confusing the issue more, some people diagnosed with dissociative identity disorder may also have sociopathic tendencies and intentionally lie about some things.
Even though pathological lying is not recognized as a clinical disorder, legal cases often require that you prove that the defendant is aware that he or she is lying. This proof is most important in cases of slander and/or liability.<SUP class=noprint title="The text in the vicinity of this tag needs citation.">[
