We investigated whether dementia risk factors were associated with prodromal Alzheimer’s disease (AD) according to the International Working Group-2 and National Institute of Aging-Alzheimer’s Association criteria, and with cognitive decline. 1394 subjects from with Mild Cognitive Impairment (MCI) from 14 different studies were classified according to these research criteria, based on cognitive performance and biomarkers. We compared the frequency of ten risk factors between the subgroups and used Cox-regression to examine the effect of risk factors on cognitive decline. Depression, obesity and hypercholesterolemia occurred more often in individuals with low-AD-likelihood, compared to those with a high-AD-likelihood. Only alcohol use increased the risk of cognitive decline, regardless of AD pathology. These results suggest that traditional risk factors for AD are not associated with prodromal AD or with progression to dementia, among subjects with MCI. Future studies should validate these findings and determine whether risk factors might be of influence at an earlier stage (i.e. preclinical) of AD. [less ▲]

Patients with Alzheimer’s disease (AD) show impairment of episodic memory and related metacognitive processes. The present study examined subjective metacognitive judgments preceding objective memory retrieval and investigated the neural correlates of pessimistic predictions for successfully retrieved memories in AD patients. AD patients and healthy older participants provided predictive judgements on their recognition performance before retrieval of famous (semantic) and recently learned (episodic) names. Correlations between grey matter volume (GMV) in T1 images and behavioural scores were examined with multivariate (PLS) and univariate (GLM) analyses in AD patients. AD patients showed a significant proportion of successful name recognition preceded by pessimistic prediction (Prediction_low_hits) in episodic memory. PLS revealed that behavioural pattern in AD patients was related with a mainly right lateralized pattern of GMV decrease including medial temporal lobe and posterior cingulate cortex, but also right ventrolateral prefrontal cortex (VLPFC). GLM further confirmed that pessimistic prediction negatively correlated with GMV in VLPFC. Thus, impaired monitoring processes (possibly influenced by inaccurate beliefs) allowing inferences about one’s own memory performance are primarily related to decrease GMV in VLPFC in AD patients.

The formation of a global and complex episodic memory requires memory for single units of information of the target event but also binding these elements together. This binding capacity diminishes in healthy aging leading to a so-called associative memory deficit. Interestingly, when support is provided during encoding thanks to semantic prior-knowledge (e.g., semantically related word pairs), this associative deficit can be alleviated. The aim of the present review is to summarize the current literature about the influence of prior-knowledge on associative memory performance in healthy aging. Through an analysis of the procedures that have been used in associative memory studies, we suggest two factors that appear to modulate the impact of prior knowledge on older adults’ associative memory. First, the way word pairs are recombined from the encoding to the retrieval phase is the main factor that has to be taken into account. Conditions that promote recall-to-reject discrimination processes lead to similar performance in older compared to younger adults, whereas conditions that require recollection discrimination lead to an age-related decline. Second, the nature of the semantic relations involved in the prior-knowledge support may influence older adults’ performance by modulating the contribution of recollection and familiarity to recognition. Indeed, categorical semantic relations engage both recollection and familiarity-based discrimination, whereas thematic relations allow participants to rely on familiarity-based discrimination only. This latest observation is crucial when one considers recollection as a declining process, in contrast to familiarity, which remains spared in healthy aging. Therefore, future studies should explore the propensity of other semantic relations to alleviate the age-related associative memory decline. [less ▲]

In Alzheimer’s disease (AD), it is now well established that recollection is impaired from the beginning of the disease, whereas findings are less clear concerning familiarity. One of the most important mechanisms underlying familiarity is the sense of familiarity driven by processing fluency. In this study, we attempted to attenuate recognition memory deficits in AD by maximizing the salience of fluency cues in two conditions of a recognition memory task. In one condition, targets and foils have been created from the same pool of letters (Overlap condition). In a second condition, targets and foils have been derived from two separate pools of letters (No-Overlap condition), promoting the use of letter-driven visual and phonetic fluency. Targets and foils were low-frequency words. The memory tasks were performed by 15 patients with AD and 16 healthy controls. Both groups improved their memory performance in the No-Overlap condition compared to the Overlap condition. Patients with AD were able to use fluency cues during recognition memory as older adults did, but this did not allow to compensate for dysfunction of recognition memory processes. [less ▲]

Les tâches de reconnaissance à choix forcé sont classiquement utilisées pour évaluer la mémoire de reconnaissance. Cependant, aucune étude n’a spécifiquement investigué l’impact du nombre d’alternatives sur les performances mnésiques des participants âgés. Nous voulons déterminer, d’une part, si le nombre d’alternatives proposées - deux ou trois – et d’autre part, si le degré de similarité entre la cible et ses leurres ont un impact sur les stratégies de récupération mises en place au cours de la tâche. Pour ce faire, nous avons recruté 20 participants jeunes et 20 participants âgés. Lors de la tâche de reconnaissance, nous leur avons demandé de choisir, parmi deux ou trois photographies de visages, celui qui a été présenté précédemment. Certains couples cibles-leurres étaient plus similaires que d’autres (partage de 60% de caractéristiques communes, contre 40%). Pour chaque item sélectionné, les participants devaient expliquer ce qui a guidé leur choix. Les premières analyses (ANOVA à mesures répétées 2 (groupes) x 2 (alternatives) x 2 (similarité) sur les deux dernières mesures, p<0,05) montrent que les performances entre les groupes sont équivalentes pour la tâche de reconnaissance à deux alternatives. A l’inverse, nous avons observé que les participants jeunes avaient significativement de meilleures performances que les âgés dans la tâche de reconnaissance à trois alternatives. Les profils mnésiques des participants seront étudiés à la lumière des modèles à deux processus de la reconnaissance. Nous faisons l’hypothèse d’un recours plus fréquent à la recollection chez les jeunes dans la tâche de reconnaissance à trois alternatives (vs deux alternatives), alors que le choix de l’item se ferait chez les âgés, en comparant directement les degrés de familiarité associés à chaque item et en sélectionnant le plus familier (Norman & O’Reilly, 2003).

Interactions between a dorsal attention (DAN) and a ventral attention cerebral network (VAN) have been reported in young participants during attention or short term memory (STM) tasks. Since it remains an under-investigated question, age effects on DAN and VAN activity and their functional balance were explored during performance of a STM task. Older and young groups showed similar behavioral patterns of results. At the cerebral level, DAN activation increased as a function of increasing STM load in both groups, suggesting preserved activity in DAN during healthy aging. Age-related over-recruitment in regions of the DAN in the higher task load raised the question of compensation attempt versus less efficient use of neural resources in older adults. Lesser decrease of VAN activation with increasing load and decreased stimulus-driven activation in the VAN, especially in the higher load, in older participants suggested age-related reduced response in the VAN. However, functional connectivity measures showed that VAN was still functionally connected to the DAN in older participants. [less ▲]

The aim of this study was to investigate the impact of test format on recollection and familiarity in normal aging and in MCI. Seventy young participants, 65 younger-old, 53 older-old, and 13 MCIs were presented with forced-choice and yes/no visual recognition memory tasks with the Remember/Know/Guess paradigm. The young people had better recognition performance than younger-old, who performed better than older-old and MCIs. Recollection and familiarity declined progressively in healthy aging. In MCI, recollection was more affected than familiarity, but patients demonstrated a more liberal use of familiarity. Finally, test format did not influence strongly the results. Young people used recollection more often in the forced-choice task compared to the yes/no task. [less ▲]
