Core Concepts & Spectrum - Decoding Deception

  • Malingering: Intentional production or gross exaggeration of physical/psychological symptoms.
    • Motivation: External incentives (e.g., avoiding duty, financial compensation, obtaining drugs).

    ⭐ Malingering is NOT a mental disorder, but a Z-code (other conditions that may be a focus of clinical attention) per DSM-5-TR.

  • Factitious Disorder (Imposed on Self / Munchausen Syndrome): Intentional production/feigning of symptoms.
    • Motivation: Internal gain (sick role); external incentives absent.
  • Factitious Disorder Imposed on Another (by Proxy): Intentional production/feigning of symptoms in another (e.g., child by caregiver).
    • Motivation: Perpetrator assumes sick role by proxy.
  • Somatic Symptom Disorder: ≥1 distressing somatic symptoms causing disruption.
    • Excessive thoughts/feelings/behaviors about symptoms. Symptoms not intentionally produced.
  • Conversion Disorder (Functional Neurological Symptom Disorder): Altered voluntary motor/sensory function.
    • Incompatible with neurological/medical conditions. Symptoms not intentionally produced.

Malingering - The External Gain Game

  • Intentional feigning or gross exaggeration of symptoms for external incentives (secondary gain).
  • Conscious, goal-directed behavior, not a mental disorder. Goals: money, avoiding duties/prosecution, drugs.
  • 📌 Mnemonic: MALI
    • Money (e.g., disability, insurance)
    • Avoidance (e.g., duty, work, legal trouble)
    • Litigation (e.g., compensation)
    • Inconsistent (symptoms vs. objective findings; poor cooperation)
  • Key Clues for Suspicion:
    • Medicolegal context of presentation (e.g., attorney referral, disability claim).

    ⭐ A marked discrepancy between claimed stress/disability and objective findings is a strong indicator of malingering.

    • Poor cooperation during evaluation and non-adherence to prescribed treatment.
    • Antisocial Personality Disorder (ASPD) often coexists.
    • Symptoms may resolve if the external gain is achieved or becomes unattainable.
  • Distinction: Factitious Disorder (motivation is internal - to assume the "sick role"), not for external material gain.

Factitious Disorder - The Internal Drama Drive

  • Intentional production or feigning of physical or psychological symptoms.
  • Motivation: Unconscious need to assume the "sick role"; primary internal psychological gain, not external (e.g., financial).
  • Patient is aware of feigning symptoms but unaware of the underlying unconscious motivation.
  • 📌 Mnemonic: SICK ROLE
    • Self-induced: Actively causes/exaggerates symptoms.
    • Inconsistent: History/findings often don't align.
    • Covert: Deception hidden from medical staff.
    • Knows-not-why: Unaware of deep psychological reasons.
    • Recurrent: Pattern of multiple hospital/doctor visits.
    • Odd: Atypical, dramatic, or bizarre presentation.
    • Likes hospitals: Seeks medical attention, procedures.
    • Empty: Linked to personality disorders/past trauma.
  • Key Forms:
    • Factitious Disorder Imposed on Self: Per DSM-5-TR criteria, characterized by "pseudologia fantastica" (pathological lying), peregrination (doctor/hospital shopping), and often dramatic, vague symptoms. May have "gridiron" abdomen.
    • Factitious Disorder Imposed on Another (FDIA): Current ICD-11 classification for cases involving harm to dependents.

⭐ Factitious Disorder Imposed on Another (FDIA) is a form of abuse with serious legal consequences under BNS provisions for child endangerment and assault.

  • Malingering: Intentional feigning for external gain (e.g., drugs, avoid work); not a mental disorder.
  • Factitious Disorder: Intentional feigning to assume the sick role; no external gain.
  • Key differentiator: Motivation - external incentives (Malingering) vs. sick role (Factitious).
  • Malingering often linked to Antisocial Personality Disorder.
  • Factitious Disorder Imposed on Another (FDIA): Inducing illness in others, often children.
  • Hospital shopping (peregrination) is common in severe Factitious Disorder.
