Munchausen syndrome by proxy (MSP) — or Munchausen by proxy — is a psychological disorder marked by attention-seeking behavior by a caregiver through those who are in their care.
MSP is a relatively rare behavioral disorder. It affects a primary caretaker, often the mother. The person with MSP gains attention by seeking medical help for exaggerated or made-up symptoms of a child in his or her care. As health care providers strive to identify what’s causing the child’s symptoms, the deliberate actions of the mother or caretaker can often make the symptoms worse.
