Abstract
AbstractPersonality changes are included in the DSM‐III‐R and ICD‐10 criteria for diagnosis of dementia. However, until quite recently, dementia research has emphasized cognitive decline, with little interest being shown in personality change. Recent studies looking at personality changes in dementia have usually used small clinical samples. In the study reported here, such changes have been assessed in a community sample of persons over 70 years. Information was obtained from a close relative or friend. A single dimension of personality change was found. There was a moderate but significant correlation between personality change and cognitive change. Reports of personality change were also correlated to neurotic symptoms in the informant. Personality change was unrelated to the gender of the informant, the relationship of the informant to their relative or whether they lived with their relative. Also, there was no association between personality change and the elderly subject's age, gender or level of education. Through logistic regression, the neurotic symptom score of the informant was found to be the best predictor of reported personality change. This suggests that caution may be needed in interpreting information about personality change obtained from informants.
