• Mentira Compulsiva
Pseudologia fantastica is one of several terms applied by psychiatrists to the behaviour of habitual or compulsive lying. It was first described in the medical literature in 1891. One definition of pathological lying is the following:
Pathological lying is 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.
The characteristics of pseudologia fantastica are: (1) the stories are not entirely improbable and often have some element of truth; (2) the stories are long lasting; (3) the stories are told for internal psychological reasons rather than external gain, and tend towards presenting the person in a good light (for example, as being fantastically brave, knowing or being related to many famous people); and (4) they are not delusional (that is, upon confrontation, the person can acknowledge them to be untrue).
Pseudologia fantastica is not currently listed as a symptom in the Diagnostic and Statistical Manual of Mental Disorders. Not much has been established about pathological lying, except that it is the mental state of the liar and not the lie that is abnormal.
