Factitious Disorder
A psychiatric disorder where individuals intentionally fake or induce illness to play the 'sick role', without external reward.
Emergency Management: Management of acute, self-induced life-threatening crises (e.g., severe hypoglycemia, sepsis, hemorrhage) which must be treated organically regardless of the cause.
Factitious disorder is a psychiatric condition characterized by the intentional falsification of physical or psychological signs and symptoms, or the induction of injury or disease, associated with identified deception. The individual presents themselves as ill, impaired, or injured, and this deceptive behavior is evident even in the absence of obvious external rewards (unlike malingering).
Detailed Overview
Patients with factitious disorder deliberately produce or exaggerate symptoms purely to assume the 'sick role', seeking medical attention, sympathy, and care. This can lead to numerous unnecessary, invasive, and potentially harmful diagnostic procedures and surgeries. It differs from somatic symptom disorder (where symptoms are not intentionally produced) and malingering (where symptoms are produced for external gain, such as financial compensation or avoiding work). When a person induces illness in another (typically a child), it is termed Factitious Disorder Imposed on Another (Munchausen syndrome by proxy).
Epidemiology & Demographics
Exact prevalence is unknown due to the deceptive nature of the disorder, but it is estimated to account for about 1% of patients in hospital settings. It is more commonly recognized in women, particularly those with a background in healthcare.
Etiological Mechanism
The exact etiology is unknown but is believed to be rooted in severe personality disorders (such as borderline personality disorder), childhood trauma, emotional abuse, or a history of frequent hospitalizations during childhood.
Primary Causes
["Psychological distress driving the need for attention and care.", "Personality pathology (e.g., borderline, narcissistic features)."]
There is no direct physiological pathology; rather, it is a psychological mechanism. However, the actions taken by patients (e.g., injecting insulin, consuming anticoagulants, contaminating wounds with feces) create real pathophysiological crises (hypoglycemia, bleeding, sepsis) that the medical team must manage.
Diagnostic Criteria & Guidelines
DSM-5 criteria: 1) Falsification of physical/psychological signs or induction of injury/disease, associated with deception. 2) The individual presents to others as ill, impaired, or injured. 3) Deceptive behavior is evident in the absence of obvious external rewards. 4) Behavior is not better explained by another mental disorder.
Management is extremely challenging. First-line approach involves a non-judgmental, gentle confrontation (or avoiding direct confrontation while removing unnecessary medical interventions). Psychotherapy (Cognitive Behavioral Therapy, CBT) is the primary treatment to address underlying trauma and coping mechanisms.
Second-Line & Adjunctive Therapy
Pharmacotherapy is not effective for factitious disorder itself, but SSRIs (e.g., Sertraline 50-200 mg/day) may be used to treat comorbid depression, anxiety, or borderline personality traits.
Surgical & Procedural Management
Absolute avoidance of unnecessary surgeries. Surgeons must be hyper-vigilant not to operate based solely on subjective complaints.
Patient Counseling & Advice
Focus counseling on emotional distress and psychological support rather than debating the reality of the medical symptoms. Build a therapeutic alliance.
Follow-Up & Monitoring Schedule
Strict multidisciplinary coordination among care teams, psychiatric follow-up, and careful monitoring of electronic medical records to prevent 'doctor shopping'.
Preventive Strategies
Early recognition of the pattern in the medical record to prevent iatrogenic harm.
Prognosis is generally poor as most patients refuse psychiatric care and continue to doctor-shop. Chronic morbidity from induced illness is high.
