What is Proxy Munchausen Syndrome (man-made disorder imposed by another)? (2023)

Key facts and examples of child abuse cases

Munchausen symptoms for power

Signs and symptoms of FDIA are likely to be present in both the caregiver and the child or adult victim. It is important for the doctor to watch for signs and symptoms on both parties and follow up on any concerns.

In the caregiver, it is important to look for the following signs:

  • caretaker deception
  • The reports of caregivers are different from those of medical personnel.
  • The caregiver has a medical background and can work in a medical environment.
  • The caregiver wants to be seen as "good" at what they do
  • The caregiver routinely seeks the approval and attention of medical personnel
  • Caregiver's refusal to leave the victim's side when assessing the victim
  • The victim's medical history is patchy, vague, or inconsistent
  • Recommendations for invasive diagnostic and surgical procedures are accepted without question or concern from the caregiver.

In addition, a caregiver often requests a second opinion, other interventions, and additional procedures. Frequently present in the caregiver are bad relationships with the family and/or lack of relationship with friends or other social networks.

Warning signs in a child or adult victim may include:

  • Reported medical problems that do not respond to treatment
  • Symptoms or signs of disease only appear in the presence of the caregiver
  • Signs and symptoms may improve under medical care
  • History of multiple and repeated injuries, illnesses, medical procedures, surgeries, and/or hospitalizations
  • Unusual presentation of a disorder or disease involving normal examination and observation by medical personnel
  • Second absent parent, in the case of a child victim


The exact cause of FDIA or Munchausen syndrome by proxy is unclear. However, experts say that both biological and psychological factors play a role in the development of this disorder.

One theory suggests that people with FDIA experienced a history of neglect or psychological, sexual, or emotional abuse as children. The caregiver may also have a psychiatric disorder, such as personality disorder, bipolar disorder, anxiety, or depression. Other theories point to the loss of a parent at an early age or great stress.

Munchausen types by proxy

Munchausen syndrome by proxy always involves a caregiver and a victim, usually a child or another adult. Munchausen syndrome, on the other hand, is when a person presents themselves to others, more specifically medical personnel, as sick.

Both are considered factitious disorders with Munchausen syndrome by proxy classified as factitious disorder imposed on another (FDIA) and Munchausen as factitious disorder self-imposed or FDIS.

In the FDIA, “other” can be a child of the caregiver, such as mother and child, or it can be another adult that the perpetrator is caring for.

The diagnosis of Munchausen syndrome by proxy is challenging for doctors because of all the dishonesty displayed by the adult caregiver. A basic principle in the diagnosis of this disorder is that deception is present in all cases.

A person with FDIA will misrepresent the history and symptoms of the adult or child victim, eventually leading to overtreatment and unnecessary medical procedures.

There is a set of criteria used to diagnose FDIA or Munchausen syndrome by proxy. To meet a clinical diagnosis, the following four criteria must be met:

  1. The abuser or caregiver engages in misrepresenting physical or psychological signs or symptoms, or inducing injury or illness in another person.
  2. The person presents the victim to others as ill, injured, or disabled.
  3. Deceptive behavior is present in the absence of external incentives.
  4. The behavior is not better explained by another mental disorder, such as a Delusional Disorder or another Psychotic Disorder.

Munchausen treatment by proxy

Treatment of FDIA or Munchausen syndrome by proxy usually requires treatment of both the adult and the child or adult victim. That being said, it can be difficult to get the perpetrator to seek treatment, as he is often unwilling to admit to her behavior or seek treatment. Often it is an intervention on the child's behalf by a doctor or other protective agency that forces the issue.

In the event that a parent/guardian is willing to receive help and is not being investigated for abuse, the treating physician should refer them to individual or family therapy. The doctor and mental health specialists should work together on a treatment plan for the family.

If the child or adult victim is removed from the perpetrator's care, treatment may involve medical and psychological interventions. FDIA victims will need psychotherapy or psychiatric treatment to help them understand and deal with the abuse they have been subjected to by a caregiver or parent.

They may also need ongoing medical follow-up to monitor any physical damage inflicted by the caregiver. The doctor and mental health specialists should form a multidisciplinary hospital or community child protection team to treat the victim.

The perpetrator or offending parent may face criminal charges related to the abuse. Treatment of the caregiver/perpetrator will depend on the legal issues related to the case and other psychiatric conditions.

Treating the Effects of Childhood Trauma


FDIA or Munchausen syndrome by proxy is a serious form of child abuse that requires immediate intervention by Child Protective Services and medical personnel.
