title: Subjective memory complaints with and without objective memory impairment: relationship with risk factors for dementia.
abstract: 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.
