BACKGROUND: Patients living in squalor have a wide range of psychiatric diagnoses, but these may have a common neural basis involving frontal systems. This study investigated frontal executive function, theory of mind, emotional processing including disgust, and appreciation of squalor in elderly patients found living in squalor. METHODS: Six patients referred to an old age psychiatry service underwent a battery of neuropsychological tests, assessment of living conditions and awareness of self and others' squalor. RESULTS: All six patients showed impairment in frontal executive function, typically accompanied by amnesic deficits. Theory of mind and emotional processing were surprisingly preserved. While five of the patients could recognize severely unclean or cluttered living conditions in newspaper photographs, more than half did not appreciate that their own living conditions were squalid. CONCLUSION: Deficits in frontal executive function appear important in the genesis of squalor although functions linked to orbito-frontal ability appear preserved.
