“…This lends support to the idea of attentional fatigability in TBI. Similarly, performance on the auditory Psychomotor Vigilance Task was reported to be impaired in patients with TBI relative to HCs, with evidence of slower response times, increased response variability and more attentional lapses [45]. Self-reported fatigue was associated with a more global impact on attention performance on this test.…”

Nearly 2 million traumatic brain injuries occur annually, most of which are mild (mTBI). One debilitating sequela of mTBI is cognitive fatigue: fatigue following cognitive work. Cognitive fatigue has proven difficult to quantify and study, but this is changing, allowing models to be proposed and tested. Here, we review evidence for four models of cognitive fatigue, and relate them to specific treatments following mTBI. The evidence supports two models: cognitive fatigue results from the increased work/effort required for the brain to process information after trauma-induced damage; and cognitive fatigue results from sleep disturbances. While there are no evidence-based treatments for fatigue after mTBI, some pharmacological and nonpharmacological treatments show promise for treating this debilitating problem. Future work may target the role of genetics, neuroinflammation and the microbiome and their role in complex cognitive responses such as fatigue.

“…With regard to executive attention, it is important to emphasize that there is extensive evidence that the neurobehavioral consequences of sleep loss can be measured through certain aspects of cognitive functioning [46][47][48]. Among the most reliable effects of sleep deprivation is degradation of attention [38,49], including vigilant attention [38,50].…”

The role of attention allocation in object-location memory has been widely studied through incidental and intentional encoding conditions. However, the relation between sustained attention and memory encoding processes has scarcely been studied. The present study aimed to investigate performance differences across incidental and intentional encoding conditions using a divided attention paradigm. Furthermore, the study aimed to examine the relation between sustained attention and incidental and intentional object-location memory performance. Based on previous findings, an all women sample was recruited in order to best illuminate the potential effects of interest. Forty-nine women participated in the study and completed the psychomotor vigilance test, as well as object-location memory tests, under both incidental and intentional encoding divided attention conditions. Performance was higher in the incidental encoding condition than in the intentional encoding condition. Furthermore, sustained attention correlated with incidental, but not with intentional memory performance. These findings are discussed in light of the automaticity hypothesis, specifically as it regards the role of attention allocation in encoding object-location memory. Furthermore, the role of sustained attention in incidental memory performance is discussed in light of previous animal and human studies that have examined the brain regions involved in these cognitive processes. We conclude that under conditions of increased mental demand, executive attention is associated with incidental, but not with intentional encoding, thus identifying the exact conditions under which executive attention influence memory performance.

“…Cumulative and probability plots of whole RT distribution were computed for a more extensive characterisation of performance deficits not necessarily captured by investigating typical PVT summary statistics alone (10,18,30). Group differences in neurobehavioral performance were examined by computing cumulative and probability distribution plots.…”

Sustained attention following traumatic brain injury: Use of the Psychomotor Vigilance Task

Abstract: The auditory PVT is a sensitive measure of sustained attention deficits in patients with TBI, with aspects of performance influenced by fatigue, sleep disturbance, and depression.
