OBJECTIVE: The authors investigated the frequency distribution of well-established risk factors for dementia--high plasma homocysteine and the apolipoprotein E epsilon4 allele (APOE epsilon4)--among older women with subjective memory complaints (SMC) but no cognitive impairment, and with mild cognitive impairment (MCI). METHODS: This was a cross-sectional, community-based study. RESULTS: Women with MCI had higher total plasma homocysteine than healthy-comparison subjects. There was also a nonsignificant excess of APOE epsilon4 carriers in the MCI than in the healthy group. Participants with SMC had higher depression and anxiety scores than healthy-comparison subjects, but did not differ from subjects in the healthy-comparison group in relation to their total plasma homocysteine and APOE epsilon4 distribution. CONCLUSIONS: MCI seems to be more closely related to well-established risk factors for dementia than is SMC.     «
