“…One might suppose that aMCI individuals in Delprado et al's study 30 mostly included single-domain aMCI individuals considering their PM deficits were more from difficulties on the RC. Despite these differences, our results are in line with previous findings that aMCI subjects exhibit greater PM deficits relative to naMCI and OA subjects 23,27 and that deficits in naMCI subjects were intermediate between OA and aMCI. 28 Research on PM is increasing in AD and MCI populations because functional and anatomical brain areas known to be impaired in these conditions parallel those involved in PM functioning.…”

“…[20][21][22] Significant PM deficits have also been reported in individuals with mild cognitive impairment (MCI), an intermediate state between normal cognitive functioning and dementia. 19,[23][24][25][26][27][28] Given its essential role in maintaining independent daily living, it would be wise to evaluate PM at a more systematic rate, especially in the aging population. Several standardized PM measures have been developed over the years.…”

Objective: Prospective memory (PM) is a cognitive function defined as the ability to perform an intention at an appropriate moment in the future. In the aging population, PM is essential for maintaining independent daily living. Introduced as a simple and quick way to assess PM in clinical settings, the envelope task has to date received very limited empirical and practical interest. Methods: The present study investigated the task's clinical utility in detecting PM impairment in a sample composed of 49 healthy older adults (OA), 41 patients with Alzheimer's disease, and 64 individuals with amnestic and nonamnestic mild cognitive impairment (MCI) of heterogeneous etiology: 17 of idiopathic nature, 20 presenting an idiopathic rapid-eye movement sleep behaviour disorder, and 27 patients diagnosed with idiopathic Parkinson's disease. Results: The envelope task was highly sensitive and specific in discriminating Alzheimer's disease patients from OA. Although it was specific in distinguishing MCI individuals from OA, its sensitivity was modest, especially in patients presenting a nonamnestic MCI subtype. Conclusions: Given its high specificity and simple low-cost administration procedure, the envelope task is a promising instrument for clinicians who seek to rapidly assess PM impairment in their daily practice.RÉSUMÉ: Contexte: La mémoire prospective (MP) est une fonction cognitive qui se définit par la capacité à effectuer une action à un moment préalablement déterminé dans le futur. La MP joue un rôle crucial chez les personnes âgées dans le maintien de leur indépendance fonctionnelle dans la vie quotidienne. Parmi les mesures de PM décrites dans la littérature, la tâche de l'enveloppe est une épreuve simple et rapide à administrer, mais pourtant rarement utilisée par les chercheurs et les cliniciens. Méthodologie: L'objectif de la présente étude était d'investiguer l'utilité clinique de cette épreuve dans la détection de troubles de la MP auprès d'un échantillon composé de 49 sujets sains, 41 patients atteints de la maladie d'Alzheimer et 64 individus ayant un trouble cognitif léger (MCI) amnésique ou non-amnésique d'étiologies hétérogènes: 17 de nature idiopathique, 20 présentant un trouble comportemental en sommeil paradoxal et 27 atteints de la maladie de Parkinson. Résultats: La tâche de l'enveloppe s'est avérée très sensible et spécifique pour discriminer les patients atteints d'une maladie d'Alzheimer des sujets sains. Sa spécificité était bonne pour discriminer les MCI des sujets sains, mais la tâche de l'enveloppe demeurait peu sensible chez les MCI surtout chez les MCI non-amnésiques. Conclusion: En raison d'une grande spécificité et de la facilité d'administration, la tâche de l'enveloppe est donc une mesure intéressante pour tout de clinicien désirant rapidement évaluer la MP dans leur pratique.

“…However, there are issues concerning the assessment of PM. First, although there are measures that have undergone validation studies and have been shown to be distinct from some unrelated concepts, measures of PM considered valid remain correlated with other measures of "higher" cognition such as working memory (Hernandez Cardenache et al, 2014;Kamat et al, 2014;Salthouse et al, 2004). While this would be theoretically expected to some extent, this raises the question whether we are measuring prospective memory specifically or simply executive function in general.…”

Associations between performance-based and self-reported prospective memory, impulsivity and encoding support

et al. 2020

Prospective memory (PM) is the ability to execute future intended actions and may be negatively affected by impulsivity. The current study aimed to address questions on (1) relationships of PM with facets of impulsivity; (2) psychometric properties of a PM task, in particular convergent validity with self-reported PM; and (3) whether external support of the encoding process would improve PM or affect relationships with impulsivity. 245 participants performed the experiment online.Participants completed either a baseline version of the task, which combined blocks of an ongoing working memory task with PM trials involving a varying stimulus requiring an alternative response; or a version that provided external support of encoding by requesting that participants visualize and execute the intended prospective action before each block. The Prospective-Retrospective Memory Questionnaire (PRMQ) and Short Version of the UPPS-P Impulsive Behavior Scale (SUPPS) were used to assess self-reported prospective memory and facets of impulsivity. Reliability of PM performance was good and remained acceptable even with the exclusion of participants with low scores. PM performance was associated with self-reported PM, explaining variance in addition to that explained by working memory performance. PM performance was also negatively associated with impulsivity, in particular sensation seeking and positive urgency, but only in the baseline task. Support did not cause overall improvements in performance. In conclusion, results provided further evidence for a relationship between facets of impulsivity and PM. PM as assessed via the current task has good psychometric properties.

“…4,5 Importantly, PM deficits may appear early in the neurodegenerative process, namely in patients that suffer from Mild Cognitive Impairment (MCI). [7][8][9][10][11][12] Beyond the actual performance in PM objective tasks, it is also important to consider the subject's self-report about PM complaints. 6 Several studies showed that patients with MCI have objective deficits in PM, using different memory tasks.…”
