Abstract
BACKGROUND Episodic memory testing is fundamental for the diagnosis of Alzheimer's disease (AD). Although the Free and Cued Selective Reminding Test (FCSRT) is widely used for this purpose, it may not be sensitive enough for early detection of subtle decline in preclinical AD. The Memory Binding Test (MBT) intends to overcome this limitation. OBJECTIVES To analyze the test-retest reliability of the MBT and its convergent validity with the FCRST. METHODS 36 cognitively healthy participants of the ALFA Study, aged 45 to 65, were included for the test-retest study and 69 for the convergent analysis. They were visited twice in a period of 6 ± 2 weeks. Test-retest reliability was determined by the calculation of the intra-class correlation coefficient (ICC). Score differences were studied by computing the mean percentage of score variation between visits and visualized by Bland-Altman plots. Convergent validity was determined by Pearson's correlations. RESULTS ICC values in the test-retest reliability analysis of the MBT direct scores ranged from 0.64 to 0.76. Subjects showed consistent practice effects, with mean amounts of score increasing between 10% and 26%. Pearson correlation between MBT and FCSRT direct scores showed r values between 0.40 and 0.53. The FCSRT displayed ceiling effects not observed in the MBT. CONCLUSIONS The MBT shows adequate test-retest reliability and overall moderate convergent validity with the FCSRT. Unlike the FCSRT, the MBT does not have ceiling effects and it may therefore be especially useful in longitudinal studies, facilitating the measurement of subtle memory performance decline and the detection of very early AD.

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.

Abstract
INTRODUCTION The Free and Cued Selective Reminding Test (FCSRT) is a memory test that controls attention and acquisition, by providing category cues in the learning process. Because it enables an assessment of memory not confounded by normal age-related changes in cognition and a high accuracy on Alzheimer's disease (AD) evaluation, it has been suggested by the International Working Group on AD. Our aim was to assess the construct related validity of the FCSRT in the AD spectrum disorders. METHOD Patients were classified in two groups according to standard criteria: amnestic mild cognitive impairment (n = 100) and AD (n = 70). A matched control group (n = 101) of cognitively healthy subjects was included. The factorial structure of two models and respective construct and diagnostic validities were analyzed. RESULTS Both models revealed adequate fit values. The appropriated convergent validity and the lack of discriminant validity support the two factors as measuring the same construct (memory ability). The recalls of the FCSRT enabled high classification accuracy and diagnostic validity for both pathological groups. CONCLUSIONS This study represents a novel contribution regarding the adequacy of the FCSRT in terms of construct and diagnostic validities and shows the interest of including both immediate (learning) and delayed (retention) recalls. It gives also new possibilities regarding the use of the FCSRT in the memory assessment of AD spectrum disorders.

Abstract
Research increasingly suggests that subjective cognitive decline (SCD) in older adults, in the absence of objective cognitive dysfunction or depression, may be a harbinger of non-normative cognitive decline and eventual progression to dementia. Little is known, however, about the key features of self-report measures currently used to assess SCD. The Subjective Cognitive Decline Initiative (SCD-I) Working Group is an international consortium established to develop a conceptual framework and research criteria for SCD (Jessen et al., 2014, Alzheimers Dement 10, 844-852). In the current study we systematically compared cognitive self-report items used by 19 SCD-I Working Group studies, representing 8 countries and 5 languages. We identified 34 self-report measures comprising 640 cognitive self-report items. There was little overlap among measures- approximately 75% of measures were used by only one study. Wide variation existed in response options and item content. Items pertaining to the memory domain predominated, accounting for about 60% of items surveyed, followed by executive function and attention, with 16% and 11% of the items, respectively. Items relating to memory for the names of people and the placement of common objects were represented on the greatest percentage of measures (56% each). Working group members reported that instrument selection decisions were often based on practical considerations beyond the study of SCD specifically, such as availability and brevity of measures. Results document the heterogeneity of approaches across studies to the emerging construct of SCD. We offer preliminary recommendations for instrument selection and future research directions including identifying items and measure formats associated with important clinical outcomes.

Abstract
The Selective Reminding Test (SRT) and the Free and Cued Selective Reminding Test (FCSRT) are multitrial memory tests that use a common "selective reminding" paradigm that aims to facilitate learning by presenting only the missing words from the previous recall trial. While in the FCSRT semantic cues are provided to elicit recall, in the SRT, participants are merely reminded of the missing items by repeating them. These tests have been used to assess age-related memory changes and to predict dementia. The performance of healthy elders on these tests has been compared before, and results have shown that twice as many words were retrieved from long-term memory in the FCSRT compared with the SRT. In this study, we compared the tests' properties and their accuracy in discriminating amnestic mild cognitive impairment (aMCI; n = 20) from Alzheimer disease (AD; n = 18). Patients with AD performed significantly worse than patients with aMCI on both tests. The percentage of items recalled during the learning trials was significantly higher for the FCSRT in both groups, and a higher number of items were later retrieved, showing the benefit of category cueing. Our key finding was that the FCSRT showed higher accuracy in discriminating patients with aMCI from those with AD.

Abstract
Amnestic mild cognitive impairment (aMCI) patients carry a greater risk of conversion to Alzheimer's disease (AD). Therefore, the International Working Group (IWG) on AD aims to consider some cases of aMCI as symptomatic prodromal AD. The core diagnostic marker of AD is a significant and progressive memory deficit, and the Free and Cued Selective Reminding Test (FCSRT) was recommended by the IWG to test memory in cases of possible prodromal AD. This study aims to investigate whether the performance on the FCSRT would enhance the ability to predict conversion to AD in an aMCI group. A longitudinal study was conducted on 88 aMCI patients, and neuropsychological tests were analysed on the relative risk of conversion to AD. During follow-up (23.82 months), 33% of the aMCI population converted to AD. An impaired FCSRT TR was significantly associated with the risk of conversion to dementia, with a mean time to conversion of 25 months. The FCSRT demonstrates utility for detecting AD at its prodromal stage, thus supporting its use as a valid clinical marker.

Abstract
The purpose was to compare the Spanish language picture version of the Free and Cued Selective Reminding Test with Immediate Recall (pFCSRT+IR) and the Mini Mental State Exam (MMSE) in identifying very mild dementia among Spanish speaking Latino patients. The tests and an independent diagnostic assessment were administered to 112 Latino patients free of medically diagnosed dementia from an urban primary care clinic. Receiver operating characteristic (ROC) curves and the area under the curve (AUC) were used to examine differences in the operating characteristics of the pFCSRT+IR and the MMSE. Cut scores were manipulated to equate sensitivities (specificities) at clinically relevant values to compare differences in specificities (sensitivities) using the Pearson Chi Square test. Youden's index was used to select the optimal cut scores. Twenty-four of the 112 primary care patients (21%) received a research dementia diagnosis, indicating a substantial burden of unrecognized dementia. MMSE scores but not free recall scores were associated with years of education in patients free of dementia. AUC was significantly higher for free recall than for MMSE. Free recall performed significantly better than the MMSE in sensitivity and in specificity. Using optimal cut scores, patients with impaired free recall were 10 times more likely to have dementia than patients with intact recall, and patients with impaired MMSE scores were 4.5 times more likely to have dementia than patients with intact scores. These results suggest that the Spanish language pFCSRT+IR may be an effective tool for dementia screening in educationally diverse Latino primary care populations.

Abstract
Background In Alzheimer's disease (AD) research patients are usually recruited from clinical practice, memory clinics or nursing homes. Lack of standardised inclusion and diagnostic criteria is a major concern in current AD studies. The aim of the study was to explore whether patient characteristics differ between study samples recruited from general practice and from a population based screening by mail within the same geographic areas in rural Northern Norway. Methods An interventional study in nine municipalities with 70000 inhabitants was designed. Patients were recruited from general practice or by population based screening of cognitive function by mail. We sent a questionnaire to 11807 individuals ≥ 65 years of age of whom 3767 responded. Among these, 438 individuals whose answers raised a suspicion of cognitive impairment were invited to an extended cognitive and clinical examination. Descriptive statistics, chi-square, independent sample t-test and analyses of covariance adjusted for possible confounders were used. Results The final study samples included 100 patients recruited by screening and 87 from general practice. Screening through mail recruited younger and more self-reliant male patients with a higher MMSE sum score, whereas older women with more severe cognitive impairment were recruited from general practice. Adjustment for age did not alter the statistically significant differences of cognitive function, self-reliance and gender distribution between patients recruited by screening and from general practice. Conclusions Different recruitment procedures of individuals with cognitive impairment provided study samples with different demographic characteristics. Initial cognitive screening by mail, preceding extended cognitive testing and clinical examination may be a suitable recruitment strategy in studies of early stage AD.

Abstract
Adults of both genders without dementia consumed a nutriceutical formulation ("NF," consisting of folic acid, B12, Vitamin E, S-adenosylmethionine, N-acetyl cysteine and Acetyl-L-carnitine), previously shown to improve cognitive performance in Alzheimer's disease, or placebo. Participants receiving NF but not placebo improved statistically and clinically in the California Verbal Learning Test II and the Trail-Making Test. Both groups improved further during a 3-month open-label extension. Additional individuals displayed identical improvement during a separate 6-month open-label trial. Performance declined to baseline following withdrawal of NF, and statistically improved when participants resumed taking NF. Additional participants receiving NF but not placebo demonstrated improvement within 2 weeks in Trail-making and Digit-Memory tests; both groups improved in a 2-week open-label extension. An increased percentage of participants > or = 74 years of age did not show improvement with NF, which may relate to age-related difficulties in adsorption and/or basal nutritional deficiencies, or age-related cognitive decline during the course of this study. These findings support the benefit of nutritional supplements for cognitive performance and suggest that additional supplementation may be required for the elderly.
