Münchausen Syndrome by Proxy: Definition, History, and Warning Signs

Münchausen syndrome by proxy (MSbP), or factitious disorder imposed on another (FDIA), is a mental health condition where a caregiver fabricates or induces illness in a dependent (child, elderly, disabled) to gain attention or sympathy.

Origin

Coined in 1977 by pediatrician Roy Meadow, named after Baron Münchausen, an 18th-century storyteller. Estimated 1–2% of hospitalized children may be victims.

Red Flags

• Multiple medical problems with symptoms that appear/disappear suddenly or improve when caregiver absent
• Lack of objective evidence for symptoms
• Caregiver overly focused on child's medical issues, derives pleasure from attention
• Caregiver interferes with treatment or refuses doctor access

Diagnosis and Treatment

Referral to mental health professional for evaluation. Treatment involves psychotherapy for caregiver and child, plus protective measures for the child's safety.
