Background Stress-related exhaustion is associated with cognitive impairment as measured by both subjective cognitive complaints (SCCs) and objective cognitive test performance. This study aimed to examine how patients diagnosed with exhaustion disorder differ from healthy control participants in regard to levels and type of SCCs, and if SCCs are associated with cognitive test performance and psychological distress. Methods We compared a group of patients with stress-related exhaustion disorder (n = 103, female = 88) with matched healthy controls (n = 58, female = 47) cross-sectionally, concerning the type and magnitude of self-reported SCCs. We furthermore explored the association between SCCs and cognitive test performance as well as with self-reported depression, anxiety and burnout levels, in the patient and the control group, respectively. Results Patients reported considerably more cognitive failures and were more likely than controls to express memory failures in situations providing few external cues and reminders in the environment. In both groups, SCCs were associated with demographic and psychological factors, and not with cognitive test performance. Conclusion Our findings underline the high burden of cognitive problems experienced by patients with exhaustion disorder, particularly in executively demanding tasks without external cognitive support. From a clinical perspective, SCCs and objective cognitive test performance may measure different aspects of cognitive functioning, and external cognitive aids could be of value in stress rehabilitation.

Stress-related exhaustion is associated with cognitive deficits, measured subjectively using questionnaires targeting everyday slips and failures or more objectively as performance on cognitive tests. Yet, only weak associations between subjective and objective cognitive measures in this group has been presented, theorized to reflect recruitment of compensational resources during cognitive testing. This explorative study investigated how subjectively reported symptoms of cognitive functioning and burnout levels relate to performance as well as neural activation during a response inhibition task. To this end, 56 patients diagnosed with stress-related exhaustion disorder (ED; ICD-10 code F43.8A) completed functional magnetic resonance imaging (fMRI) using a Flanker paradigm. In order to investigate associations between neural activity and subjective cognitive complaints (SCCs) and burnout, respectively, scores on the Prospective and Retrospective Memory Questionnaire (PRMQ) and the Shirom-Melamed Burnout Questionnaire (SMBQ) were added as covariates of interest to a general linear model at the whole-brain level. In agreement with previous research, the results showed that SCCs and burnout levels were largely unrelated to task performance. Moreover, we did not see any correlations between these self-report measures and altered neural activity in frontal brain regions. Instead, we observed an association between the PRMQ and increased neural activity in an occipitally situated cluster. We propose that this finding may reflect compensational processes at the level of basic visual attention which could go unnoticed in cognitive testing but still be reflected in the experience of deficits in everyday cognitive functioning.

Background

People diagnosed with stress-related exhaustion disorder report high levels of cognitive symptoms. This study aimed to explore how persons diagnosed with Exhaustion disorder (ED) experienced cognitive functioning and recovery 6-10 years after participating in a rehabilitation programme. Specifically, it investigated the experiences of current functioning, change over time, and what had been barriers or facilitators for cognitive recovery.

Methods

Semi‐structured interviews were conducted for 38 persons previously diagnosed with ED (Mean age: 52; Females: 32) and explored using thematic analysis.

Results

The analysis resulted in four themes: “’It’s different now’: Remaining cognitive symptoms”, “The bigger picture: Cognitive recovery in context”, “Overcoming challenges: Strategies for coping with cognitive symptoms”, and “The approach towards cognition matters”. The participants’ experiences varied but included descriptions on how cognitive functioning had become better with some remaining symptoms. These difficulties were reported across cognitive domains, yet often centred around upholding executive control. Cognitive recovery was seen in the context of overall well-being and recovery which differed between the participants. Facilitators and barriers thus varied between persons, and included both restorative and compensatory strategies, external conditions, the degree of worry, and development of a more acceptant or self-compassionate view on cognition and oneself.

Conclusions

The results show that cognitive recovery in ED is multifaceted. 6-10 years after rehabilitation, experiences included improvement of everyday cognitive functioning, but also lingering challenges, often related to maintenance of executive control. Recovery was influenced by factors such as general well-being, restorative or compensatory strategies, worrying, or the adaptation of more accepting or self-compassionate perspectives. The findings indicate a need for tailored, person-centred approaches to supporting cognitive recovery.
