years old. The average duration from onset of symptoms to diagnosis was 22 months. By the time of diagnosis, six percent of the affected persons were dead, mostly from apnea (a common result of smothering) or starvation, and seven percent had long-term or permanent injury. About half of the affected had siblings; 25% of the known siblings were dead, and 61% of siblings had symptoms similar to the affected or that were otherwise suspicious. The mother was the perpetrator in 76.5% of the cases, the father in 6.7%. Most present about three medical problems in some combination of the 103 different reported symptoms. The most-frequently reported problems are apnea (26.8% of cases), anorexia or feeding problems (24.6% of cases), diarrhea (20%), seizures (17.5%), cyanosis (blue skin) (11.7%), behavior (10.4%), asthma (9.5%), allergy (9.3%), and fevers (8.6%). Other symptoms include failure to thrive, vomiting, bleeding, rash, and infections. Many of these symptoms are easy to fake because they are subjective. A parent reporting that their child had a fever in the past 24 hours is making a claim that is impossible to prove or disprove. The number and variety of presented symptoms contribute to the difficulty in reaching a proper diagnosis. Aside from the motive (most commonly attributed to be a gain in attention or sympathy), another feature that differentiates FDIA from "typical" physical child abuse is the degree of premeditation involved. Whereas most physical abuse entails lashing out at a child in response to some behavior (e.g., crying, bedwetting, spilling food), assaults on the FDIA victim tend to be unprovoked and planned. Also unique to this form of abuse is the role that health care providers play by actively, albeit unintentionally, enabling the abuse. By reacting to the concerns and demands of perpetrators, medical professionals are manipulated into a partnership of child maltreatment. Challenging cases that defy simple medical explanations may prompt health care providers to pursue unusual or rare diagnoses, thus allocating even more time to the child and the abuser. Even without prompting, medical professionals may be easily seduced into prescribing diagnostic tests and therapies that may be painful, costly, or potentially injurious to the child. If the health practitioner resists ordering further tests, drugs, procedures, surgeries, or specialists, the FDIA abuser makes the medical system appear negligent for refusing to help a sick child and their selfless parent. Like those with Munchausen syndrome, FDIA perpetrators are known
