Munchausen Syndrome By Proxy – A Rare but Dangerous Mental Disorder

Munchausen Syndrome By Proxy (MSBP) is a rare but serious type of mental disorder characterized by the act of a caregiver or parent fabricating or inducing illness in a child, vulnerable adult or pet for personal gratification or attention.

History and Naming

The term ‘Munchausen Syndrome by Proxy’ was coined by Sir Roy Meadows in 1977, named after Baron Karl Friedrich von Munchausen, an 18th-century German aristocrat known for his tall tales and exaggerated stories.

In MSBP, a parent or caregiver, often the mother, fabricates or exaggerates symptoms in the child, giving rise to unnecessary medical treatments and interventions.

Symptoms and Diagnosis

Signs and symptoms of MSBP can be difficult to detect, as the caregiver or parent may present with the child frequently to healthcare professionals, often lying about the child’s symptoms and seeking attention or sympathy from medical staff. However, a few common signs and symptoms that may raise suspicion include:

  • Repeated hospitalizations or medical procedures with no clear reason
  • Unexplained illness or symptoms that do not fit the medical diagnosis
  • Disproportional or inconsistent symptoms reported by the caregiver or parent or observed by the medical team
  • Medical records that have anomalies
  • Caregiver or parent with a medical or nursing background or who works in a medical field
  • Child who becomes sick only when in the presence of the caregiver or parent

The diagnosis of MSBP requires a multi-disciplinary team effort, involving physicians, child psychiatrists, forensic experts in child abuse, and social workers, who will investigate the medical history of the child and the caregiver or parent’s psychological and emotional state.

Causes and Risk Factors

The exact cause of MSBP remains unclear, but some theories suggest that it may be linked to psychological factors such as a low self-esteem, trauma or abuse, or mental illness such as borderline personality disorder or Munchausen Syndrome.

There may also be external factors such as attention-seeking behaviour, a need for control, or a history of substance abuse that can contribute to a caregiver or parent engaging in MSBP. A high level of stress or anxiety in the caregiver or parent can also be a contributing factor.

Treatment and management

The primary intervention for managing MSBP is to remove the child from the caregiver or parent’s care and place them in a safe environment. Parents or caregivers who have been identified as engaging in MSBP may be prosecuted and held accountable for their actions.

The child may require psychological or psychiatric care to address the trauma caused by the repeated medical interventions and the abuse of trust by the caregiver or parent. The child’s medical records also need review to ensure that an accurate medical diagnosis is made, and appropriate interventions made.

Caregivers or parents identified with MSBP also require psychological or psychiatric care to address the psychological and emotional factors driving their behaviours. A team of mental health professionals will work together to develop a personalised treatment plan, which may include therapy, counselling, or medication management.


Preventing MSBP involves educating healthcare professionals and the public about the indications, signs, and symptoms. Healthcare professionals are encouraged to look out for these symptoms and report any findings to the appropriate authorities.

The public must be made aware of the dangers of MSBP, how it can occur, and how to report any concerning behaviours immediately.


Munchausen Syndrome By Proxy remains a rare but dangerous mental disorder that can have long-lasting effects on the child or vulnerable adult. Addressing it requires a multi-disciplinary approach, involving physicians, mental health professionals, social workers, and forensic experts in child abuse.

Early detection, intervention, and proper management are critical for the well-being of the child or vulnerable adult and the caregiver or parent. Raising awareness, educating the public, and building a strong collaborative relationship between healthcare professionals and the community play a vital role in preventing and managing MSBP.
