#PATHOLOGICAL LIAR SYMPTOMS MANUAL#
Pathological lying 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. Some psychiatrists distinguish compulsive from pathological lying, while others consider them equivalent yet others deny the existence of compulsive lying altogether this remains an area of considerable controversy. For example, the person might be presented as being fantastically brave, as knowing or being related to many famous people, or as having great power, position, or wealth. The liar "decorates their own person" by telling stories that present them as the hero or the victim. The stories told tend toward presenting the liar favorably.An internal motive for the behavior cannot be readily discerned clinically: e.g., long-lasting extortion or habitual spousal battery might cause a person to lie repeatedly, without the lying being a pathological symptom.

Others have defined pathological lying as "falsification entirely disproportionate to any discernible end in view, may be extensive and very complicated, and may manifest over a period of years or even a lifetime." These lies often serve no obvious purpose other than to paint oneself as a hero or victim, depending on the circumstance. Pathological lying, also known as mythomania and pseudologia fantastica, is a chronic behavior in which the person habitually or compulsively lies.
