- Exhaustion disorder (ED) is a stress-related disorder that often implies a great burden on the individual patient as well as on society. Previous studies have shown that ED is associated with metabolic deviations, such as lowered fasting glucose. Several mechanisms have been discussed as a plausible explanation of the lack of energy described by these patients. Metabolic processes and reduced ability to mobilize energy have been suggested as important factors. This study investigated metabolomics in 20 patients diagnosed with ED and compared them with 21 healthy controls. Plasma metabolic profiles were examined in both fasting and nonfasting (postprandial) conditions. Blood plasma samples were analyzed for metabolite content using gas chromatography mass spectrometry. A total of 62 different metabolites were simultaneously detected in each of the samples. Multivariate models indicated systematic differences between patients with ED and healthy controls in both their fasting and nonfasting plasma metabolite levels. Lysine and octadecenoic acid were more abundant and glutamine, glycine, serine and gluconic acid were less abundant in the patients across both conditions. In the present study, we comprehensively and simultaneously screen for changes in a large number of metabolites. Our results show a difference in systemic metabolites between patients with exhaustion disorder and healthy controls both in the fasting and in the postprandial states. Here, we present new potential biomarkers mirroring exhaustion disorder metabolism.

- Cognitive impairment has frequently been shown in patients who seek medical care for stress-related mental health problems. This study aims to extend the current knowledge of cognitive impairments in these patients by focusing on perceived fatigue and effects of distraction during cognitive testing. Executive function and attention were tested in a group of patients with stress-related exhaustion (n=25) and compared with healthy controls (n=25). Perceived fatigue was measured before, during and after the test session, and some of the tests were administered with and without standardized auditory distraction. Executive function and complex attention performance were poorer among the patients compared to controls. Interestingly, their performance was not significantly affected by auditory distraction but, in contrast to the controls, they reported a clear-cut increase in mental tiredness, during and after the test session. Thus, patients with stress-related exhaustion manage to perform during distraction but this was achieved at a great cost. These findings are discussed in terms of a possible tendency to adopt a high-effort approach despite cognitive impairments and the likelihood that such an approach will require increased levels of effort, which can result in increased fatigue. We tentatively conclude that increased fatigue during cognitive tasks is a challenge for patients with stress-related exhaustion and plausibly of major importance when returning to work demanding high cognitive performance.

- Stress-related exhaustion has been linked to a pattern of selective cognitive impairments, mainly affecting executive functioning, attention and episodic memory. Little is known about potential treatments of these cognitive deficits. The purpose of the present study was to evaluate the effects of a process-based cognitive training intervention, designed to target the specific cognitive impairments associated with stress-related exhaustion. To this end, patients diagnosed with exhaustion disorder (ED) were randomized to either a multimodal stress rehabilitation program with the addition of a process-based cognitive training intervention (training group, n = 27) or a treatment-as-usual control condition, consisting of multimodal stress rehabilitation with no additional training (control group, n = 32). Treatment effects were evaluated through an extensive cognitive test battery, assessing both near- and far transfer effects, as well as self-report forms regarding subjective cognitive complaints and burnout levels. Results showed pronounced training-related improvements on the criterion updating task (p < 0.001). Further, evidence was found of selective near transfer effects to updating (p = 0.01) and episodic memory (p = 0.04). Also, the trained group reported less subjective memory complaints (p = 0.02) and levels of burnout decreased for both groups, but more so for the trained group (p = 0.04), following the intervention. These findings suggest that process-based cognitive training may be a viable method to address the cognitive impairments associated with ED.

- Stress-related exhaustion has been associated with selective and enduring cognitive impairments. However, little is known about how to address cognitive deficits in stress rehabilitation and how this influences stress recovery over time. The aim of this open-label, parallel randomized controlled trial (ClinicalTrials.gov: NCT03073772) was to investigate the long-term effects of 12 weeks cognitive or aerobic training on cognitive function, psychological health, and work ability for patients diagnosed with exhaustion disorder (ED). One-hundred-and-thirty-two patients (111 women) participating in multimodal stress rehabilitation were randomized to receive additional cognitive training (n = 44), additional aerobic training (n = 47), or no additional training (n = 41). Treatment effects were assessed before, immediately after and one-year post intervention. The primary outcome was global cognitive function. Secondary outcomes included domain-specific cognition, self-reported burnout, depression, anxiety, fatigue and work ability, aerobic capacity, and sick-leave levels. Intention-to-treat analysis revealed a small but lasting improvement in global cognitive functioning for the cognitive training group, paralleled by a large improvement on a trained updating task. The aerobic training group showed improvements in aerobic capacity and episodic memory immediately after training, but no long-term benefits. General improvements in psychological health and work ability were observed, with no difference between interventional groups. Our findings suggest that cognitive training may be a viable method to address cognitive impairments for patients with ED, whereas the effects of aerobic exercise on cognition may be more limited when performed during a restricted time period. The implications for clinical practice in supporting patients with ED to adhere to treatment are discussed
