Abstract/Results: ABSTRACT:
Does breath count training alter brain electric activity? Breath counting is a basic exercise for meditation. Since meditation has been suggested as migraine treatment, we wanted to determine whether breath count training affects brain activity assessed with EEG. On attack free days, 19-channel EEG were recorded from 16 migraine patients (mean age 38.3 years, SD=7.72; 12 women) during initial resting, breath counting (repeatedly count one to ten for 5 minutes) and final resting, all with eyes closed. Seven of these patients were assigned to do one month of breath count training; thereafter, all EEG recordings were repeated. EEG was spectral analyzed versus average reference; mean relative power across channels was computed in the eight independent frequency bands. EEG-LORETA funtional imaging was used to localize changes observed in the head surface EEG recordings. ANOVA’s (2 sessions x 2 conditions x 2 groups) for the 8 frequency bands revealed no main effects, but an interaction (p=0.058) in the theta frequency band. In this band, post-hoc tests showed, during the second session, a significant power increase from initial to final resting only in the trained group. LORETA functional tomography revealed that the observed differences consisted in significantly (corrected for multiple testing) increased voxel strength in left parietal areas. In sum, state-dependent learning effects were observed in the EEG after one-month training of breath counting: these effects occurred not in the resting state, but in the state immedialy after having completed a breath count exercise.

EEG power spectra, LORETA areas and self-rated headache pain
Publication year: 2010

http://www.med.uni-giessen.de/physio/Kognitive_Neurophysiologie_2010_3_1.pdf
Abstract/Results: ABSTRACT:
How is the subjective intensity of headache reflected in EEG power spectra, and where in the brain is the origin? In 16 migraine patients (without aura, 6 medicated; mean age 38.3 years, SD=7.7; 12 women), we recorded 19-channel EEG during initial resting (4 minutes) on an attack-free day. Patients visual-analog self-rated headache intensity. On average/patient, 65.6 s artifact-free EEG was available. For each of the eight independent EEG frequency bands, means of spectral power across channels (absolute and relative), and LORETA functional images (absolute and relative voxel strength) were computed, and correlated with subjective headache intensity. The correlations were negative (p<0.1) with absolute power in the delta, alpha2, beta1 and 3, and gamma bands, but positive (p<0.1) with relative power in delta and beta2. Absolute LORETA voxel strength (corrected for multiple testing p<0.1) correlated negatively in all bands but delta; relative voxel strength correlated positively with delta through alpha1. Negative correlations with absolute LORETA strength concerned only left anterior voxels in theta and alpha1, only left-hemispheric in beta1 and beta2, predominantly left in alpha1 and beta3, but more right in gamma; all positive correlations with relative strength were right anterior (delta, theta and alpha1). Medicated and unmedicated patients showed agreeing tendencies. Thus, with increasing headache intensity, EEG absolute power decreased, localizing in the left hemisphere (some frequency bands predominantly anterior), while relative strength increased exclusively right anterior. The results suggest that increasing headache intensity is associated with increasing left- hemispheric anterior-weighted activation. Supported in part by Bial Foundation Grant 44-06

Title:
Exposure to first-person shooter videogames is associated with multisensory temporal precision and migraine incidence
Publication year: 2021
URL:
https://www.sciencedirect.com/science/article/abs/pii/S0010945220303907
Abstract/Results: ABSTRACT:
Adaptive interactions with the environment require optimal integration and segregation of sensory information. Yet, temporal misalignments in the presentation of visual and auditory stimuli may generate illusory phenomena such as the sound-induced flash illusion, in which a single flash paired with multiple auditory stimuli induces the perception of multiple illusory flashes. This phenomenon has been shown to be robust and resistant to feedback training. According to a Bayesian account, this is due to a statistically optimal combination of the signals operated by the nervous system. From this perspective, individual susceptibility to the illusion might be moulded through prolonged experience. For example, repeated exposure to the illusion and prolonged training sessions partially impact on the reported illusion.
Therefore, extensive and immersive audio-visual experience, such as first-person shooter videogames, should sharpen individual capacity to correctly integrate multisensory information over time, leading to more veridical perception. We tested this hypothesis by comparing the temporal profile of the sound-induced illusion in a group of expert first-person shooter gamers and a non-players group. In line with the hypotheses, gamers experience significantly narrower windows of illusion (~87 ms) relative to non-players (~105 ms), leading to higher veridical reports in gamers (~68%) relative to non-players (~59%). Moreover, according to recent literature, we tested whether audio-visual intensive training in gamers could be related to the incidence of migraine, and found that its severity may be directly proportioned to the time spent on videogames. Overall, these results suggest that continued training within audio-visual environments such as first-person shooter videogames improves temporal discrimination and sensory integration. This finding may pave the way for future therapeutic strategies based on self-administered multisensory training. On the other hand, the impact of intensive training on visual-related stress disorders, such as migraine incidence, should be taken into account as a risk factor during therapeutic planning.

Long-term persistent headache after SARS-CoV-2 infection: A follow-up population-based study
Publication year: 2025
URL:
https://doi.org/10.1111/ene.70130
Abstract/Results: ABSTRACT:
Background
Headache is a symptom of the long-COVID syndrome. The incidence and characteristics of de novo post-COVID headaches remain unclear. Our aim was to characterize new-onset headaches in a population-based prospective cohort of COVID-19 patients from the first pandemic wave.
Methods
This study followed a prospective cohort of 732 COVID-19 patients consecutively diagnosed between March and June 2020. Neurological follow-up was performed face-to-face or by phone at 3, 12, and 24 months. A structured clinical questionnaire was used to characterize headaches before infection and 24 months postinfection.
Results
Overall, 448 patients completed the 24-month follow-up, with a mean age of 51.6 years at SARS-CoV-2 infection; 272 (60.7%) were women. A prior history of headaches was reported by 115 (25.7%). Patients with either pre-existing or de novo persistent headaches were younger, more often women, and exhibited hyposmia, hypogeusia, and headache during the acute phase of infection. De novo persistent headaches occurred in 54 of 333 (16.2%) headache-naïve patients. Of these, 35 (64.8%) fulfilled migraine-like headache (MLH) criteria (mean age of 49.1 years at 24-month follow-up), with a cumulative incidence of 42/1000/year.
Conclusions
De novo persistent headaches are common 2 years after COVID-19, with MLH being the most frequent type. MLH incidence after COVID-19 is elevated and de novo “migraineurs-like” tend to be older compared to the general population. This is an important finding with potential implications for healthcare and quality of life, considering the high number of COVID-19 cases and the global burden of migraine.
