Executive dysfunction is frequently reported in Alzheimer's disease (AD) and the frontal variant of frontotemporal dementia (FTD). More specifically, inhibitory dysfunction is observed early in AD and inhibitory deficits are also prominent in patients with FTD. However, few studies have simultaneously explored and compared inhibitory abilities in both degenerative diseases. Consequently, the aim of this study was to compare verbal and motor inhibitory processes in the initial stages of AD and the frontal variant of FTD. Stroop and Go/No-go tasks were administered. The results demonstrate that, on the Go/No-go task, AD and FTD patients do not produce more errors than control subjects. However, both groups are impaired on the Stroop task (mainly with regard to the error score) but do not differ from each other. These results indicate that AD and FTD patients do not present a general impairment of their inhibitory abilities. Moreover, these two kinds of dementia present similar quantitative and qualitative inhibitory impairments on the two tasks, although their patterns of structural and functional cerebral impairments are known to be different. The presence of similar inhibitory deficits despite very different patterns of brain damage is in agreement with the hypothesis that inhibitory dysfunction in the two groups of patients depends on a disconnection process between anterior and posterior cerebral areas, rather than on the presence of focal metabolism decreases in different regions.

The aim of this study was to evaluate the discriminant validity of the RI-48 test, a shorter French version of the Category Cued Recall portion of the Double Memory Test developed initially by Buschke and colleagues (1997), in the diagnosis of mild and very mild Alzheimer disease (AD). The distinctive feature of the RI-48 task is that encoding specificity was increased by adding an immediate cued recall stage at the encoding phase. The results show that the RI-48 task seems to be well adapted to the clinical context and to have good psychometric properties, in particular a lack of a ceiling effect. Moreover, this task appears to be especially well suited for the diagnosis of both mild and very mild AD (sensitivity of 93% and 83.8%). From a more theoretical point of view, this study confirms the importance of optimizing the encoding specificity for the diagnosis of very mild AD, since the more encoding specificity is accentuated, the more discriminating power is increased for the diagnosis of very mild AD.

A decrease in controlled processes has been proposed to be responsible for age-related episodic memory decline. We used the Process Dissociation Procedure, a method that attempts to estimate the contribution of controlled and automatic processes to cognitive performance, and entered both estimates in regression analyses. Results indicate that only controlled processes explained a great part of the age-related variance in a word recall task, especially when little environmental support was offered.

Une approche en termes de frontières d’effi cacité peut être utilisée pour étudier les relations entre les fonctions cognitives des personnes âgées de plus de 50 ans en Europe d’une part, et différents facteurs, plus particulièrement l’âge, l’éducation et l’exercice d’activités, professionnelles ou non, d’autre part. Le but est de construire une « frontière » correspondant au fonctionnement cognitif optimal que chacun des individus est censé atteindre étant donné son âge et son niveau d’éducation. À cette fi n, nous utilisons des données individuelles collectées durant la première vague de l’enquête internationale et interdisciplinaire Share de 2004, laquelle contient le résultat de tests cognitifs réalisés auprès de plus de 22 000 individus âgés, ainsi que des informations sur leur état de santé, mentale et physique, leur situation socio-économique, leur entourage familial, l’exercice d’activités professionnelles ou non professionnelles, l’isolement social et les performances cognitives individuelles mesurées à l’aide de tests. En plus du rôle fondamental joué par l’éducation face au vieillissement cognitif, le fait de rester en activité, ainsi que la pratique d’une activité non professionnelle ou d’activités physiques, vigoureuses ou modérées, sont positivement associés à la constitution des « réserves cognitives » individuelles. La mise à disposition des données des vagues successives de Share , prévues tous les deux ans auprès des mêmes individus, pourrait permettre de déterminer les liens de causalité subjacents. [less ▲]

This paper proposes the use of the stochastic frontier approach to analyse the relationship between cognitive performance, retirement and non-professional activities of the 50+ individuals using data from three surveys conducted in Europe (the Survey on Health, Ageing and Retirement in Europe and the English Longitudinal Survey on Ageing) and United States (the Health and Retirement Study). Next to the strong relationship between cognitive performance, age and education, this study highlights the negative effect of retirement and the positive impact of non-professional activities and social contacts.
