Objective: to investigate the relationship between pre-morbid personality and behavioural and psychological symptoms of dementia (BPSD).
Methods: we studied 58 subjects with dementia and depression and/or psychosis residing in 11 Sydney nursing homes cross-sectionally. Informal caregivers completed ratings of residents' pre-morbid personality on the NEP Five-Factor Inventory (NEO-FFI). Information on BPSD was obtained using the BEHAVE-AD.
Results: higher neuroticism was predictive of delusions; higher agreeableness of hallucinations, aggressiveness, affective disturbance and overall behavioural disturbance; and higher openness of affective disorder.
Conclusion: our findings are inconsistent with previous research and clinical experience. Prospective studies are needed to clarify the association between personality and behavioural disturbance in dementia.
