7. Fatigue bei unipolarer Depression, immunologischen und (neuro-) inflammatorischen Erkrankungen: die Rolle des ZNS-Arousal

- Abstract
Pathologische Fatigue wird von PatientInnen mit einem breiten Spektrum immunologischer, (neuro-) inflammatorischer und psychiatrischer Erkrankungen berichtet. Dabei kann Fatigue sowohl ein Zustand ausgeprägter Tagesschläfrigkeit, Energie- und Antrieblosigkeit sein (i.S.v. sickness behavior; häufig beobachtet im Kontext immunologischer und (neuro-)inflammatorischer Prozesse), als auch ein Zustand der Erschöpfung mit einer hohen inneren Anspannung, Antriebshemmung und Einschlafstörungen, welcher typisch für unipolare Depression ist. Um diese auf der physiologischen Ebene diametral entgegengesetzten Zustände auseinanderzuhalten, wurde eine Unterteilung in Fatigue mit Hypoarousal und Fatigue mit Hyperarousal vorgeschlagen (Hegerl et al., 2013). Die zugrundeliegenden Unterschiede des ZNS-Arousal und seiner Regulation können objektiv mittels EEG erfasst werden. Das ZNS-Arousal bildet ein Spektrum globaler Hirnfunktionszustände, die auf der Verhaltensebene von angespannter Wachheit über Ruhewachzustand und Dösigkeit bis in den Tiefschlaf reichen und auf der elektrophysiologischen Ebene unterschiedlichen EEG-Vigilanzstadien entsprechen. Die Mehrheit der gesunden ProbandInnen zeigt während eines 15-minütigen Ruhe-EEG mit geschlossenen Augen einen kontinuierlichen Abfall der Vigilanzstadien bis hin zum Einschlafen; nur wenige verbleiben in höheren Vigilanzstadien oder zeigen einen raschen Abfall in niedrige Stadien. Demgegenüber verbleiben depressive PatientInnen deutlich länger in höheren Vigilanzstadien (hyperstabile Arousalregulation), während bei PatientInnen mit tumorbedingter Fatigue niedrigere Vigilanzstadien früher und häufiger auftreten als bei gesunden Kontrollen (instabile Arousalregulation).

The term fatigue is not only used to describe a sleepy state with a lack of drive, as observed in patients with chronic physical illnesses, but also a state with an inhibition of drive and central nervous system (CNS) hyperarousal, as frequently observed in patients with major depression. An electroencephalogram (EEG)-based algorithm has been developed to objectively assess CNS arousal and to disentangle these pathophysiologically heterogeneous forms of fatigue. The aim of this study was to test the hypothesis that fatigued patients with CNS hyperarousal score higher on depressive symptoms than those without this neurophysiological pattern. Methods: Subjects with fatigue (Multidimensional Fatigue Inventory sum-score > 40) in the context of cancer, neuroinflammatory, or autoimmune diseases were drawn from the 60+ cohort of the Leipzig Research Center for Civilization Diseases. CNS arousal was assessed by automatic EEG-vigilance stage classification using the Vigilance Algorithm Leipzig (VIGALL 2.1) based on 20 min EEG recordings at rest with eyes closed. Depression was assessed by the Inventory of Depressive Symptomatology (IDS-SR). Results: Sixty participants (33 female; median age: 67.5 years) were included in the analysis. As hypothesized, fatigued patients with CNS hyperarousal had higher IDS-SR scores than those without hyperarousal (F1,58 = 18.34; p < 0.0001, η2 = 0.240). Conclusion: hyperaroused fatigue in patients with chronic physical illness may be a sign of comorbid depression.

Background Affective stimulation entails changes in brain network patterns at rest, but it is unknown whether exogenous emotional stimulation has a prolonged effect on the temporal dynamics of endogenous cortical arousal. We therefore investigated differences in cortical arousal in the listener following stimulation with different attachment‐related narratives. Methods Resting‐state EEG was recorded from sixteen healthy subjects for ten minutes each with eyes closed: first at baseline and then after passively listening to three affective narratives from strangers about their early childhood experiences (prototypical for insecure‐dismissing, insecure‐preoccupied, and secure attachment). Using the VIGALL 2.1 algorithm, low or high vigilance stages in consecutive EEG segments were classified, and their dynamic profile was analyzed. Questionnaires assessed the listeners’ emotional response to the content of the narrative. Results As a general effect of preceding affective stimulation, vigilance following the stimulation was significantly elevated compared to baseline rest, and carryover effects in dynamic vigilance profiles were observed. A difference between narrative conditions was revealed for the insecure‐dismissing condition, in which the decrease in duration of high vigilance stages was fastest compared to the other two conditions. The behavioral data supported the observation that especially the insecure narratives induced a tendency in the listener to affectively disengage from the narrative content. Discussion This study revealed carryover effects in endogenous cortical arousal evoked by preceding affective stimulation and provides evidence for attachment‐specific dynamic alterations of brain states and individual differences in emotional reactivity.
