Munchhausen by proxy syndrome in clinical child neuropsychology: A case presenting with neuropsychological symptoms

Munchhausen by proxy syndrome (MBPS) is a rare but dramatic variant of child abuse. In MBPS adults, mostly the mother, invent, manipulate, or produce the child's illness, and as a consequence the child has to undergo numerous diagnostic or treatment procedures. Typically, valid information about the etiology of the child's illness is withheld by the parents, and reversible symptoms vanish, when the child and the responsible adults are separated. Although valid statistical data about the epidemiology of MBPS are not available, MBPS should be considered more often than normally recognized. Neurological and neuropsychological presentations including developmental delays and learning problems appear to be common among MBPS cases so that clinical child neuropsychologists should be aware of this problem and consider MBPS at least in some of the mysterious cases that come to their attention. The present study describes a case of MBPS in which neurological and neuropsychological symptoms predominate. It presents a MBPS variant that is characterized by developmental delays and learning problems induced by unnecessary isolation at home, hospitalization, and treatment procedures. In the present case MBPS was at first suspected following neuropsychological assessment, since some of the main features of non-authenticity of symptom presentation gave cause for suspecting deceptive behavior on the mother's (and possibly also on the maternal grandmother's) side.
