Individuals diagnosed with depression (n = 23) and healthy controls (n = 31) were included in the study. A 15-minute sustained attention task (subtest of the Test Battery for Attention, version 2.3.1) was administered with concurrent electroencephalographic recordings to evaluate P300 amplitude and latency. Peripheral inflammation was assessed by measuring IL-6, IL-1β, and TNF-α levels. Perceived fatigue was assessed using the German version of the Fatigue Impact Scale. Generalized linear models (GLM) were used to evaluate the main aims of the study. Results indicated that depression was associated with reduced P300 amplitudes (p = 0.011), and age was significantly associated with P300 amplitude, with older participants showing reductions (p = 0.016). However, no significant effects of inflammatory markers on P300 components were found. While no group differences were observed in the total number of hits, both perceived fatigue (p = 0.033) and TNF-α (p = 0.007) were significantly associated with hit accuracy. A post-hoc mediation analysis explored that perceived fatigue mediates the relationship between depression and number of hits. These findings suggest that low-grade inflammation may not directly influence P300 components, though inflammation and fatigue appear linked to accuracy deficits. Finally, the impact of depression on the number of hits is primarily mediated by perceived fatigue, suggesting that fatigue is a crucial factor in how depression affects cognition.</div></div>","PeriodicalId":52767,"journal":{"name":"Biomarkers in Neuropsychiatry","volume":"12 ","pages":"Article 100121"},"PeriodicalIF":0.0,"publicationDate":"2025-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143387470","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recent biomarker research in AD shows alterations in anatomical, biochemical and physiological pathways as well as in endocrinological processes. Perceived stress is one of the factors often reported in relation to the onset and the course of AD. Hence, the function of the hypothalamus-pituitary-adrenal (HPA) axis, the endogenous system regulating the stress response homeostasis, may serve as biomarker in disease etiology and response to treatment. Vice versa, successful treatment could have an advantageous effect on the function of the HPA system. In the present review, we summarize findings on the HPA system in relation to AD and first results on its modifiability in response to cognitive behavioral therapy (CBT), one of the most efficacious psychotherapeutic treatments for AD. We specifically focus on findings of experimental studies that explored cortisol levels before, during and after exposure-based CBT. A systematic search was conducted in MEDLINE/PubMed, PsycINFO, Web of Science, and in references of retrieved studies until April 2024. The inclusion criteria were studies enclosing keywords related to the HPA axis, an anxiety disorder and CBT techniques. The results of the summarized studies suggest that cortisol levels have the potential to indicate the AD disease status and serve as possible biomarker in outcome prediction. Global dysfunction of the HPA system seems to point to higher symptom burden and less advantageous response to CBT. Furthermore, low cortisol levels elicited in relation to exposure interventions are repeatedly associated with risk for non-response. Additionally, some evidence suggests that successful CBT containing exposure sessions as well as cognitive techniques induces normalization of the HPA system by reducing acute response to fear related stimuli in parallel to normalizing basal cortisol levels. To conclude, cortisol seems to be a promising candidate to depict several aspects of AD-related disease status and CBT effects, however, additional prospective studies are needed to evaluate the mode of applications of this marker in the clinical routine.</div></div>","PeriodicalId":52767,"journal":{"name":"Biomarkers in Neuropsychiatry","volume":"12 ","pages":"Article 100116"},"PeriodicalIF":0.0,"publicationDate":"2024-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143181167","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
