Abstract
BACKGROUND: Subjective memory impairment (SMI) refers to subjective
awareness of initial memory decline undetectable with existing standardized cognitive
tests. The Face Name Associative Memory Exam (FNAME) was created to detect memory deficits
in individuals with preclinical Alzheimer’s disease (AD). We reported normative data of a
Spanish version of FNAME (S-FNAME) in cognitively normal (CN) Spanish-speaking subjects
>49.
OBJECTIVE: To determine whether higher SMI [a modification of Memory
Failures Everyday (MFE-30)] was related to worse memory performance (S-FNAME)
or associated with greater affective symptoms in subjects >49; and whether MFE-30 and
FNAME were able to discriminate between CN and mild cognitive impairment (MCI)
subjects.
METHODS: 317 subjects (CN = 196, MCI = 121) were included in the analysis
because they attended the annual “Open House Initiative” at Memory Clinic Fundació ACE,
were >49 years, literate, received S-FNAME, MFE-30, and Hospital Anxiety and Depression
Scale, had Mini-Mental State Examination scores ≥27, and returned to complete a
comprehensive diagnostic assessment.
RESULTS: MFE-30 scores were associated with affective symptoms but not with
S-FNAME performance. S-FNAME scores were related to performance on memory variables of
NBACE (neuropsychological battery used in Fundació ACE). Although the MCI group showed
significantly higher MFE-30 and worse S-FNAME scores than the CN group, their
discriminability values were similar (Sensitivity: 49.6 versus 52.9; Specificity: 85.1
versus 83.6, respectively).
CONCLUSIONS: SMI was more related to depressive symptoms than to S-FNAME
memory performance; and S-FNAME scores were related to other episodic memory test
performances, but neither to affective symptoms nor to SMI. MFE-30 and S-FNAME are not
optimal for discriminating between CN and MCI groups. Longitudinal follow-up will
determine if lower S-FNAME and higher SMI are related to increased risk of AD.
