Subjective memory complaints and cognitive performance in a sample of healthy elderly pot
... 2008;2(1):42-4514 women and 13 men, aged 69.6±5.4 years, with mean educational level of 8.8 years. Mean MMSE score of this group was 27.8.The group of complainers (MAC-Q scores ≥25) was composed by 25 women and 8 men, aged 70.3±7.0 years, with mean educational level of 8.2 years. Mean MMSE score of this group was 27.2.No significant difference for age, gender, education and MMSE scores were found between the two groups. Table 1 depicts the main demographic data as well as the MMSE and MAC-Q values for both groups. The comparison between the performance of the groups of complainers and non-complainers on the dif-ferent cognitive tests yielded no significant difference, al-though there was a trend for non-complainers to perform better in incidental memory.Table 2 presents the scores from the two groups in all tests as well as the statistical comparisons between them.Discussion In the present study, we found no significant difference in the performance of elderly subjects with and without SMCs on a series of brief cognitive tests assessing attention, episodic and semantic memory, and executive functions. Only a trend toward a significant difference emerged for the subtest of incidental memory from the BCSB, an item that is more related to attention than to memory itself.Some previous studies have found a relationship be-tween SMCs and objective memory performance, while many others have not.2 The methodology adopted by the different studies in assessing SMC varies, where some use only a simple question about perceived memory problems, while others base this classification on the results of specific questionnaires, such as the MAC-Q used in our study. Interestingly, a previous Brazilian study compared the use of the MAC-Q with direct questioning about memory problems, and found that a significant percentage of the sample had SMCs, based on the response to the direct ques-tion along with low scores on MAC-Q, while other subjects had no SMCs and high MAC-Q scores.18 Performance on a memory test did not differ according to the MAC-Q re-sults, mirroring our findings, although was worse in those individuals presenting SMCs upon direct questioning.High age, female gender and low education have all been associated with an increased prevalence of SMCs. Our sample is composed exclusively by elderly subjects (≥60 years), with a predominance of women (39 vs. 21) and with low to middle educational level, especially com-paring with studies conducted in North America, Europe or Japan. These features might explain the high percentage (55%) of individuals presenting SMCs.Memory complaints are recognized to be frequent within the elderly population, especially among those with depressive and anxiety symptoms.19,20 In our study, depres-sion is very unlikely as an explanation for the high preva-lence of SMCs, since the presence of significant depressive symptoms, based on the results from the Cornell scale, was part of the exclusion criteria.SMCs have been more related to future cognitive de-cline rather than to current memory deficits.2 Indeed, in a recent study, the presence of SMCs was found to be a sig-nificant predictor of subsequent decline, although without a “dose-effect” relationship.21 Moreover, in this same study the investigators observed that the occurrence of SMCs also increased the probability of an unstable diagnosis. We still have no longitudinal data on the cognitive performance of our study participants to be able to contribute to this debate, but we may be able to re-evaluate at least part of the sample in the future in order to replicate such observations. An issue that has not been addressed in our study is the Table ... envelhecimento, memória, cognição, testes neuropsicológicos.Behavioral and Cognitive Neurology Unit, Department of Internal Medicine, Faculty of Medicine, Federal University of Minas Gerais, Belo Horizonte, Brazil.Paulo Caramelli – Department of Internal Medicine / Faculty of Medicine / Federal University of Minas Gerais - Avenida Prof. Alfredo Balena, 190 / Room 246 - 30130-100 Belo Horizonte MG - Brazil.

In a recent Brazilian study, Minett et al. found that subjects with and without SMCs performed similarly in a series of cognitive tests, although the former had higher scores on the Geriatric Depression Scale.5The present study aimed to further investigate this topic in a group of cognitively healthy Brazilian elderly subjects which were divided into two subgroups according to the presence of SMCs and submitted to brief cognitive tests.MethodsSixty cognitively intact elderly individuals (39 females and 21 males), aged 69.9±6.3 years (ranging from 60 to 91 years), and with mean educational level of 8.5±5.5 years (ranging from 1 to 20 years), were included in the study. These individuals were family caregivers of demented pa-tients followed at the Behavioral and Cognitive Neurology Unit of the Faculty of Medicine of the Federal University of Minas Gerais, in Belo Horizonte (MG), Brazil, and also volunteers recruited from the community.Inclusion criteria were absence of neurological or psy-chiatric diseases according to a clinical interview, absence of depression (see below), and no use of benzodiazepines, antidepressants or neuroleptics. All participants were submitted to the Mini-Mental State-Examination (MMSE)6,7 and to the Cornell scale of depression.8,9 Performance on the MMSE was adjusted for educational level and had to be greater than or equal to 21 for 1-3 years of schooling, greater than or equal to 24 for 4-7 years and greater than or equal to 26 for individuals with 8 or more years of schooling.10 Scores on the Cornell scale of depression had to be less than or equal to 7 points in order to rule out depression.8Cognitive evaluation was carried out with the follow-ing tests: the Brief Cognitive Screening Battery (BCSB)11,12, digit span forward and backward and the Frontal Assess-ment Battery (FAB).13,14 The BCSB includes a memory test of 10 simple figures and yields different scores, namely: incidental and immediate memory, learning, delayed recall and recognition.15,16 The battery also includes a category fluency test (animals per minute) and clock drawing and has proven very sensitive in the diagnosis of mild AD.12 The FAB is a brief diagnostic instrument for the assessment of executive functions in patients with suspected frontal lobe syndrome.13All individuals were given a structured self-report memory questionnaire, the MAC-Q.17 This questionnaire was devised to assess age-related memory decline. It is composed by six questions related to memory function-ing in everyday situations (e.g., to remember a telephone number that he/she uses at least once a week) in which the subject is asked to compare and rate his/her current ability to when he/she was 40 years’ old. The total score on the MAC-Q ranges from 7 to 35, where greater scores in- dicate subjective memory loss. Scores greater than or equal to 25 have been found to be suggestive of age-associated memory impairment. Accordingly, in the present study, the individuals were divided into two groups: absence of SMCs (MAC-Q scores <25) and presence of SMCs (MAC-Q scores ≥25). The performance of the two groups on the different cognitive tests was compared.One of the authors administered the MMSE, the Cor-nell scale and the MAC-Q. Subsequently, the other inves-tigator, blinded to the subjects’ results for these three mea-sures, administered the cognitive evaluation.Descriptive analysis of the data and statistical compari-sons between the performances of the two groups on the different cognitive tests were carried out with MedCalc software. Student’s t-test was used for comparison of age, educational level and MMSE scores, as well as for the results of the other cognitive tests (digit span, BCSB and FAB). Chi-square was employed for comparing gender distribu-tion of the two groups. Level of significance was set at 0.05. The study was approved by the Research Ethics...
