TY - JOUR A1 - Blume, Marie A1 - Schmidt, Ricarda A1 - Schmidt, Jennifer A1 - Martin, Alexandra A1 - Hilbert, Anja T1 - EEG Neurofeedback in the Treatment of Adults with Binge-Eating Disorder: a Randomized Controlled Pilot Study JF - Neurotherapeutics N2 - Specific alterations in electroencephalography (EEG)-based brain activity have recently been linked to binge-eating disorder (BED), generating interest in treatment options targeting these neuronal processes. This randomized-controlled pilot study examined the effectiveness and feasibility of two EEG neurofeedback paradigms in the reduction of binge eating, eating disorder and general psychopathology, executive functioning, and EEG activity. Adults with BED and overweight (N = 39) were randomly assigned to either a food-specific EEG neurofeedback paradigm, aiming at reducing fronto-central beta activity and enhancing theta activity after viewing highly palatable food pictures, or a general EEG neurofeedback paradigm training the regulation of slow cortical potentials. In both conditions, the study design included a waiting period of 6 weeks, followed by 6 weeks EEG neurofeedback (10 sessions à 30 min) and a 3-month follow-up period. Both EEG neurofeedback paradigms significantly reduced objective binge-eating episodes, global eating disorder psychopathology, and food craving. Approximately one third of participants achieved abstinence from objective binge-eating episodes after treatment without any differences between treatments. These results were stable at 3-month follow-up. Among six measured executive functions, only decision making improved at posttreatment in both paradigms, and cognitive flexibility was significantly improved after food-specific neurofeedback only. Both EEG neurofeedback paradigms were equally successful in reducing relative beta and enhancing relative theta power over fronto-central regions. The results highlight EEG neurofeedback as a promising treatment option for individuals with BED. Future studies in larger samples are needed to determine efficacy and treatment mechanisms.

Schätzungsweise ein bis zwei Prozent der Allgemeinbevölkerung leiden unter TTM. Gemeinsam mit anderen pathologischen körperbezogenen repetitiven Verhaltensweisen ist TTM in DSM-5 und ICD-11 dem Zwangsspektrum zugeordnet. In der Ätiologie stehen lerntheoretische Modelle im Vordergrund. Zur Behandlung wird die Kognitive Verhaltenstherapie empfohlen, wobei insbesondere Nachweise zur Effektivität des Habit-Reversal-Trainings vorliegen. Derzeit liegt keine evidenzbasierte Empfehlung für eine spezifische pharmakologische Behandlung vor. TTM ist bis heute ein wenig erforschtes und in der Praxis unzureichend bekanntes Störungsbild. Der vorliegende Beitrag liefert einen Überblick über den aktuellen Forschungsstand und allgemeine Handlungsempfehlungen für die Praxis.

Version der Internationalen statistischen Klassifikation der Krankheiten und verwandter Gesundheitsprobleme (ICD-11) findet sich erstmals die Kategorie der Körperbezogenen repetitiven Verhaltensstörungen (engl. „body-focused repetitive behavior disorders“, BFRBDs), die u. a. die Trichotillomanie (TTM) sowie die Skin-Picking-Störung (SPS) enthält und dem Zwangsspektrum zugeordnet ist. Diese Neuerung umfasst sowohl die Neukategorisierung der TTM, die in der ICD-10 noch bei den „abnormen Gewohnheiten und Störungen der Impulskontrolle“ verortet war, als auch die erstmalige Einführung einer eigenständigen Diagnose für die SPS. Trotz beachtlicher Prävalenzen (TTM: 1–2 %; SPS: 1,4–3,1 %) wurden die TTM und die SPS bislang in Fachkreisen wenig beachtet, was sich neben einem hohen Forschungsbedarf – auch in Bezug auf die nosologische Verortung – insbesondere in mangelhaften Versorgungsangeboten widerspiegelt. Bezüglich der Einordnung im Zwangsspektrum ist kritisch anzumerken, dass die Störungsbilder zwar Ähnlichkeiten mit der Zwangsstörung zeigen, aber dennoch fundamentale Unterschiede in Symptomatik, Ätiologie und Behandlung zu beachten sind. In diesem Kontext sollte davon abgesehen werden, TTM und SPS pauschal als Zwangsstörungen zu bezeichnen. Vielmehr sollten die individuellen Besonderheiten der BFRBD, die sich bei Betroffenen durch eine impulshafte, zwanghafte oder auch suchtartige Phänomenologie äußern können, individuell und differenziert analysiert und behandelt werden, um die bestmögliche Versorgung zu gewährleisten. Insgesamt bietet die Einführung der BFRBD-Kategorie mit einer eigenständigen Diagnose für die SPS in der ICD-11 wichtige Chancen zur Verbesserung der Forschungs- und Versorgungslage.

Method: In this experimental study, the influence of health-related and social stressors on subjective and physiological reactivity was investigated in 29 subjects with SSD without any medical condition SSD(mc−), 33 subjects with SSD with medical condition SSD(mc+) and 32 healthy controls at the age from 18 to 70 years. Self-report and physiological variables were measured before and after/during stressor exposure, using state ratings of symptom intensity, disability, tension and mood, heart rate (HR), and heart rate variability (HRV). Results: Overall, the tension increased and the mood worsened after exposure to stressors compared to pre-exposure. Compared to HC, the two SSD groups showed higher symptom intensity, disability, tension and worse mood. The SSD(mc−) group revealed higher HR than HC (p = .012, d = −0.77). Compared to pre-exposure, symptom impairment increased after social stressor exposure in SSD(mc−) (p < .001, d = 1.36). HRV-root mean square of successive differences (RMSSD) only decreased in HC during exposure (p = .003, d = −1.09), not in the SSD groups. The two SSD groups did not differ in their reactivity to stressors. Conclusion: HRV in SSD, seems to respond less flexibly to stressors, potentially reflecting overall physiological disturbance through reduced parasympathetic influence on HR. Stress reactivity in SSD(mc−) and SSD(mc+) do not seem to differ.

Its unpleasant symptoms may limit the acceptance of VR technologies for training or clinical purposes. Mechanical stimulation of the mastoid and diverting attention to pleasant stimuli-like odors or music have been found to ameliorate VIMS. Chewing gum combines both in an easy-to-administer fashion and should thus be an effective countermeasure against VIMS. Our study investigated whether gustatory-motor stimulation by chewing gum leads to a reduction of VIMS symptoms. 77 subjects were assigned to three experimental groups (control, peppermint gum, and ginger gum) and completed a 15-min virtual helicopter flight, using a VR head-mounted display. Before and after VR exposure, we assessed VIMS with the Simulator Sickness Questionnaire (SSQ), and during the virtual flight once every minute with the Fast Motion Sickness Scale (FMS). Chewing gum (peppermint gum: M = 2.44, SD = 2.67; ginger gum: M = 2.57, SD = 3.30) reduced the peak FMS scores by 2.05 (SE = 0.76) points as compared with the control group (M = 4.56, SD = 3.52), p < 0.01, d = 0.65. Additionally, taste ratings correlated slightly negatively with both the SSQ and the peak FMS scores, suggesting that pleasant taste of the chewing gum is associated with less VIMS. Thus, chewing gum may be useful as an affordable, accepted, and easy-to-access way to mitigate VIMS in numerous applications like education or training. Possible mechanisms behind the effect are discussed.
