Solitary Psychosis — Three Cases of Monosymptomatic Delusion of Alimentary Stench Treated with Behavioural Psychotherapy

Abstract

SummaryThree cases of monosymptomatic delusion of alimentary stench are described. Each patient was referred for behaviour therapy as a last resort, after extensive medical investigation for halitosis or flatulence and failure of other psychiatric treatment. Two of the patients showed clinical improvement after treatment sustained at follow-up. Monosymptomatic delusion is now a treatable condition and is important to diagnose.
