“…However, this hypothesis was not supported by our findings as premorbid personality traits did not predict BPS in the AD group, although clear correlations were observed when the AD and control groups were lumped together, an artifact due to the combination of two clinically clearly distinct and homogeneous groups. Similarly, other studies found no relationship between premorbid personality traits and BPS in AD patients (Swearer et al, 1996;Holst et al, 1997;Brandt et al, 1998). Thus, the impact of premorbid neuroticism on the occurrence of depression in mild AD as suggested by some studies (Chatterjee et al, 1992;Strauss et al, 1997;Meins et al, 1998;Gilley et al, 2004) was not supported by our findings, although depression and neuroticism scores were quite high in these patients.…”
