[Delirious and hallucinatory disorders in late psychoses with the pattern of "home paranoia"]

Paranoid and hallucination syndromes were studied in 71 cases of senile non-dementia psychoses located at the patients' house. Two major variants were singled out: paranoid and hallucinatory (the latter subdivided into patterns with or without the persecution delusion, and physical affection delusion). Paranoid variant was shown to be based upon a special transformation of visual perception with formation of delusions of penetration of a "stranger" into the patients' home. Hallucinatory variants were based predominantly on primitive physically-straining hallucinations with protopathic meaning. As the paranoid syndrome increased in severity, the space of its projection onto housing place expanded. It is suggested that housing conditions themselves could influence the psychopathology of housing paranoid.
