These lies often serve no obvious purpose other than to paint oneself as a hero or victim, depending on the circumstance.
[Treanor KE. Defining, understanding, and diagnosing pathological lying (pseudologia fantastica): an empirical and theoretical investigation into what constitutes pathological lying octor of Psychology (Clinical) Thesis Wollongong, NSW: School of Psychology, University of Wollongong; 2012. Available at: https://ro.uow.edu.au/theses/3811/. Accessed December 2, 2019] Pathological lying has been defined as: "a persistent, pervasive, and often compulsive pattern of excessive lying behavior that leads to clinically significant impairment of functioning in social, occupational, or other areas; causes marked distress; poses a risk to the self or others; and occurs for longer than six months."
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."
It was first described in the medical literature in 1890 by G. Stanley Hall and in 1891 by .
There is still much controversy in the fields of psychology and psychiatry about whether or not pathological lying is a unique disorder or merely a symptom of other disorders. A widely agreed-upon description of or diagnostic criteria for pathological lying behaviour does not exist, resulting in controversy regarding what it truly means to be a pathological liar. Theories to explain the root causes include stress, an attempt to shift a locus of control
Locus of control is the degree to which people believe that they, as opposed to external forces (beyond their influence), have control over the outcome of events in their lives. The concept was developed by Julian B. Rotter in 1954, and has since ...
to an internal one, and issues relating to low self-esteem.
Characteristics
Defining characteristics of pathological lying include:
* 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.
* The stories told tend toward presenting the liar favorably. The liar "decorates their own person" by telling stories that present them as the hero or the victim. 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.
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.

of abandonment. Pathological liars do not feel rejected; they have high levels of self-assurance that help them lie successfully. Unlike those with histrionic personality, pathological 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.

. This diagnosis deals with people who lie about having physical or psychological disorders. However, research or testing must be done to confirm the individual does not in fact have a physical or other 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 history. Because the symptoms do not match up, the individual may go undiagnosed. They could well be diagnosed under the catch-all rubric

Pathological liars
Lying is the act of both knowingly and intentionally or willfully making a false statement. Normal lies are defensive and are told to avoid the consequences of truth telling. They are often white lies that spare another's feelings, reflect a pro-social attitude, and make civilized human contact possible. Pathological lying can be described as an habituation of lying. It is when an individual consistently lies for no obvious personal gain.
There are many consequences of being a pathological liar. Due to lack of trust, most pathological liars' relationships and friendships fail. If this continues to progress, lying could become so severe as to cause legal problems, including, but not limited to, fraud.
Epidemiology
The average age of onset is before adulthood. Individuals with the condition tend to have average verbal skills as opposed to performance abilities. Thirty percent of subjects had a chaotic home environment, where a parent or other family member had a mental disturbance. Its occurrence was found by the study to be equal in women and men. Forty percent of cases reported central nervous system abnormality such as epilepsy, abnormal EEG findings, ADHD, head trauma, or CNS infection
There are five main causes of infections of the central nervous system (CNS): bacterial, viral, fungal, protozoal, and prionic.
Fungal

* Brain abscess
* Spinal epidural infection
Protozoal
* Toxoplasmosis
* Malaria
