Abstract Introduction Sleep loss that is inherent to military operations can lead to cognitive errors and potential mission failure. Single Nucleotide Polymorphisms (SNPs) allele variations of several genes (COMT, ADORA2A, TNFa, CLOCK, DAT1) have been linked with inter-individual cognitive resilience to sleep loss through various mechanisms. U.S. Army Soldiers with resilience-related alleles may be better-suited to perform cognitively-arduous duties under conditions of sleep loss than those without these alleles. However, military-wide genetic screening is costly, arduous, and infeasible. This study tested whether a brief survey of subjective resilience to sleep loss (1) can demarcate soldiers with and without resilience-related alleles, and, if so, (2) can predict cognitive performance under conditions of sleep loss. Methods Six SNPs from the aforementioned genes were sequenced from 75 male U.S. Army special operations Soldiers (age 25.7±4.1). Psychomotor vigilance, response inhibition, and decision-making were tested after a night of mission-driven total sleep deprivation. The Iowa Resilience to Sleeplessness Test (iREST) Cognitive Subscale, which measures subjective cognitive resilience to sleep loss, was administered after a week of recovery sleep. A receiver operating characteristic (ROC) curve was used to determine whether the iREST Cognitive Subscale can discriminate between gene carriers, and a cutoff score was determined. Cognitive performance after sleep deprivation was compared between those below/above the cutoff score using t-tests or Mann-Whitney U tests. Results The iREST discriminated between allele variations for COMT (ROC=.65,SE=.07,p=.03), with an optimal cutoff score of 3.03 out of 5, with 90% sensitivity and 51.4% specificity. Soldiers below the cutoff score had significantly poorer for psychomotor vigilance reaction time (t=-2.39,p=.02), response inhibition errors of commission (U=155.00,W=246.00,p=.04), and decision-making reaction time (t=2.13,p=.04) than Soldiers above the cutoff score. Conclusion The iREST Cognitive Subscale can discriminate between those with and without specific vulnerability/resilience-related genotypes. If these findings are replicated, the iREST Cognitive Subscale could be used to help military leaders make decisions about proper personnel placement when sleep loss is unavoidable. This would likely result in increased safety and improved performance during military missions. Support (if any) Support for this study came from the Military Operational Medicine Research Program of the United States Army Medical Research and Development Command.

Serum Bdnf

The protein brain derived neurotrophic factor (BDNF) is a major contributor to neuronal plasticity. There is numerous evidence that BDNF expression is decreased by experiencing psychological stress and that accordingly a lack of neurotrophic support causes depression. The use of serum BDNF concentration as a potential indicator of brain alteration is justified through extensive evidence. Recently, we reported, for the first time, a relationship between BDNF and insomnia, since we could show that reduced levels of serum BDNF are correlated with sleep impairment in control subjects, while partial sleep deprivation was able to induce a fast increase in serum BDNF levels in depressed patients. Using a bi-directional stress model as an explanation approach, we propose the hypothesis that chronic stress might induce a deregulation of the HPA system leading in the long term to sleep disturbance and decreased BDNF levels, whereas acute sleep deprivation, can be used as therapeutical intervention in some insomniac or depressed patients as compensatory process to normalize BDNF levels. Indeed, partial sleep deprivation (PSD) induced a very fast increase in BDNF serum levels within hours after PSD which is similar to effects seen after ketamine infusion, another fast-acting antidepressant intervention, while traditional antidepressants are characterized by a major delay until treatment response as well as delayed BDNF level increase. Moreover, we revealed that stress experience and subjective sleep perception interact with each other and affect serum BDNF levels. We identified sleep as a mediator of the association between stress experience and serum BDNF levels.Disclosure of interestThe authors have not supplied their declaration of competing interest.
