mythomania
C2 (Very Low Frequency - Specialized/Vocational)Formal, Clinical, Technical, Literary
Definition
Meaning
An abnormal or pathological tendency to exaggerate or tell lies.
A compulsive or habitual condition involving the fabrication of falsehoods, often grandiose in nature, which the teller may come to believe. In clinical contexts, it is sometimes associated with factitious disorder or certain personality disorders. In broader usage, it can describe an extreme, persistent pattern of deceitful behavior.
Linguistics
Semantic Notes
The term implies a persistent, compulsive condition rather than an isolated act of lying. It often suggests the constructed falsehoods are elaborate and self-aggrandizing. It is not a formal psychiatric diagnosis in major diagnostic manuals but is used descriptively in psychology, psychiatry, and criminology.
Dialectal Variation
British vs American Usage
Differences

Connotations

Frequency
Extremely low frequency in both varieties, almost exclusively found in specialized texts, true crime, or sophisticated literary analysis.

Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct calque from Russian 'мифомания' as it is a very low-frequency loanword; 'патологическая ложь' (pathological lying) is the more common equivalent. Do not confuse with 'меломания' (melomania) which is about music.
Common Mistakes
- Confusing it with 'megalomania' (delusions of grandeur). While related, megalomania is about power/importance, mythomania is about falsehoods. Spelling: 'mythoMANia' (not 'mythoPHANia'). Using it to describe a single, trivial lie.

FAQ
Frequently Asked Questions
No. While all mythomaniacs are liars, the term specifies a pathological, compulsive, and habitual condition, often where the person may believe their own falsehoods. Simple lying is a behavior; mythomania implies a deeper psychological pattern.
It is not listed as a discrete disorder in major diagnostic manuals like the DSM-5 or ICD-11. It is a descriptive term used in clinical and forensic contexts, often overlapping with features of factitious disorder, narcissistic personality disorder, or as 'pseudologia fantastica'.
Treatment is challenging as it involves deep-seated personality patterns. Psychotherapy, particularly cognitive-behavioral therapy (CBT), may be attempted to address underlying issues like low self-esteem or trauma that fuel the compulsive deceit.
Confabulation typically involves the unconscious filling of memory gaps with fabricated stories, often due to neurological conditions (e.g., amnesia). Mythomania is more conscious, deliberate, and motivated by psychological needs like grandiosity or gaining sympathy, though the teller may lose insight.
