Phantom boarder symptom (PBS) is a hallucinatory and delusional syndrome that tends to occur in the elderly, in which the patient imagines that someone uninvited is living in their home. This article provides an overview of the historical background that has led to the current focus on PBS as a single symptom, from its classification as late paraphrenia to its being recognized as a type of misidentification, and discusses classification problems and PBS subclassifications. In addition, the results of our own investigation of PBS, which focused on PBS in senile dementia, support the findings of previous studies, such as the absence of a relationship between dementia severity and the occurrence of delusion. The discussion therefore focuses on the psychosocial factors that serve as the mechanism of PBS onset, and directions and possibilities for therapy are suggested.
