“…On the other hand, the correlation between Hβ GPS and pain intensity (VAS d ) was only at the edge of significance, whereas VAS d was positively correlated with HAD anx . Interestingly, emerging data suggest that Hβ GPS could possibly be related to anxiety and similar mood disorders, pointing out rather an increase of β oscillations in this context (Roohi-Azizi et al, 2017;Ribas et al, 2018). In contrast, our data failed to show that the correlation between Hβ GPS and HAD anx .…”

Beta Electroencephalographic Oscillation Is a Potential GABAergic Biomarker of Chronic Peripheral Neuropathic Pain

This preliminary investigation aimed to assess beta (β) oscillation, a marker of the brain GABAergic signaling, as a potential objective pain marker, hence contributing at the same time to the mechanistic approach of pain management. This case–control observational study measured β electroencephalographic (EEG) oscillation in 12 right-handed adult male with chronic neuropathic pain and 10 matched controls (∼55 years). Participants were submitted to clinical evaluation (pain visual analog scale, Hospital Anxiety, and Depression scale) and a 24-min high-density EEG recording (BIOSEMI). Data were analyzed using the EEGlab toolbox (MATLAB), SPSS, and R. The global power spectrum computed within the low (Lβ, 13–20 Hz) and the high (Hβ, 20–30 Hz) β frequency sub-bands was significantly lower in patients than in controls, and accordingly, Lβ was negatively correlated to the pain visual analog scale (R = −0.931, p = 0.007), whereas Hβ correlation was at the edge of significance (R = −0.805; p = 0.053). Patients’ anxiety was correlated to pain intensity (R = 0.755; p = 0.003). Normalization of the low and high β global power spectrum (GPS) to the GPS of the full frequency range, while confirming the significant Lβ power decrease in chronic neuropathic pain patients, vanished the significance of the Hβ decrease, as well as the correlation between Lβ power and pain intensity. Our results suggest that the GABAergic Lβ EEG oscillation is affected by chronic neuropathic pain. Confirming the Lβ GPS decrease and the correlation with pain intensity in larger studies would open new opportunities for the clinical application of gamma-aminobutyric acid-modifying therapies.

Background: Quarantine/confinement is an effective measure to face the Coronavirus disease 2019 (COVID-19). Consequently, in response to this stressful situation, people confined to their homes may change their everyday eating behavior. Therefore, the primary objective of this study is to evaluate the association between quarantine/confinement stressors and eating behavior during the COVID-19 outbreak. The secondary objective is to evaluate the association of quarantine/ confinement stressors and eating behavior amongst two groups of participants selected from the population: individuals attending diet clinics and individuals who are not attending diet clinics.Method: A cross-sectional web-based online survey carried out between April 3 and 18, 2020, enrolled 407 participants from the Lebanese population. Eating Disorder Examination – Questionnaire (EDE-Q) were used to measure the behavioral features of eating disorders. Results: More than half of the sample (53.0%) abide to the home quarantine/confinement, 95.4% were living with someone in the quarantine/confinement and 39.6% continued to work from home. Using the lower scores as reference group, higher fear of COVID-19 was found in 182 (44.8%) participants, higher boredom in 200 (49.2%) participants, higher anger in 187 (46.3%) and higher anxiety in 197 (48.5%) participants. A greater fear of COVID-19 (Beta=0.02), higher BMI (Beta=0.05), and physical activity (Beta=1.04) were significantly associated with a higher restraint score. Higher anxiety, higher fear of COVID-19, higher BMI, practicing physical exercise and higher number of adults living in the quarantine/confinement were significantly associated with a higher shape and weight concern. Conclusion: Our results showed that the fear of COVID-19 was correlated with more restraint eating, weight, and shape concern in the whole sample and more specifically in the dietitian clients group. Public health control measures are needed to define factors of eating disorders during the quarantine/confinement period related to the COVID-19 outbreak.

“…Thus, the link between nodal CCs in DMN-related regions and state and trait anxiety suggests more negative internalized attention in patients with BD 15 . Furthermore, the high beta band frequency domain has been shown to be related to anxiety 75,76 . The altered DMN activity in the beta frequency band was repeatedly observed in patients with BD [49][50][51] .…”

Studies comparing bipolar disorder (BD) and major depressive disorder (MDD) are scarce, and the neuropathology of these disorders is poorly understood. This study investigated source-level cortical functional networks using resting-state electroencephalography (EEG) in patients with BD and MDD. EEG was recorded in 35 patients with BD, 39 patients with MDD, and 42 healthy controls (HCs). Graph theory-based source-level weighted functional networks were assessed via strength, clustering coefficient (CC), and path length (PL) in six frequency bands. At the global level, patients with BD and MDD showed higher strength and CC, and lower PL in the high beta band, compared to HCs. At the nodal level, compared to HCs, patients with BD showed higher high beta band nodal CCs in the right precuneus, left isthmus cingulate, bilateral paracentral, and left superior frontal, belonging to the default-mode network (DMN); however, patients with MDD showed higher nodal CC only in the right precuneus compared to HCs. Although both MDD and BD patients had similar global level network changes, they had different nodal level network changes in DMN-related regions. Our findings might suggest more altered network in the DMN-related regions in patients with BD than in those with MDD.
