Subjective Cognitive Fatigue in Multiple Sclerosis Depends on Task Length

Abstract: Objective: The objective of this paper is to investigate the interrelationship between subjective and objective cognitive fatigue, information processing domain [processing speed (PS) vs. working memory (WM)], cognitive load (high vs. low), and time on task in Multiple Sclerosis (MS).Methods: Thirty-two MS participants and 24 healthy controls completed experimental tasks in both the PS and WM domains with different levels of cognitive load. Subjective cognitive fatigue was measured using a visual analog scale … Show more

“…In a similar manner, cognitive measures were the subject of some studies. While some studies have found a correlation between self-reported fatigue and each of attention [80,165], memory [165] and information processing speed [3,142]; others failed to detect such a relationship [5,158,194]. The discrepancy in these findings might lie in the difference among the trials in terms of chosen cohorts and/or employed motor/cognitive tasks (e.g.…”

“…Our findings provide new evidence of an evoked oxygen metabolism facet of fatigue and neurological disability in MS. The study of neural factors related to fatigue and neurological disability is of considerable importance as these maladies are key features of MS [e.g., Sandry et al, ; Sehle et al, ] and contribute substantially to these patients' quality of life [Amato et al, ]. Here, evoked CMRO 2 responses accounted for 65% of the variance in MS patients' fatigue scores and 55% of the variance in their neurological disability scores (CBF also showed a large effect relationship with fatigue, but no significant relationship with neurological disability).…”

“…Indeed, only a handful Some of the studies in Table 1 refer to an a priori guiding theory, or pre-specified underlying mechanism(s), to understand the construct of cognitive fatigability construct 11,13,15,17 . For instance A good example is, Sandry et al 15 where the authors set out to test cognitive load 16 , cognitive domain 27 , and temporal fatigue hypotheses 28 . More theoretically guided mechanistic work is needed to understand fatigability.…”

“…We differentiate between the demanding or continuous cognitive task and the measure of fatigability used alongside this task. If we apply the definition of cognitive fatigability as a significant decline in processing speed, reaction time, or accuracy over time, after completing demanding cognitive tasks, 1,5 oOf the 21 studies outlined in Table 1, 9 eleven show support for proposed measures of cognitive fatigability 6,7,11,13,15,17,20,21,23 , indicated by an (*), next to the author's name, whilst 10 8 do not. 9,12,14,16,18,19,25,26 [ Table 1 Here]…”
