Decoding Pain Sensitivity in Migraine With Multimodal Brainstem-based Neurosignature

Migraine is a highly prevalent and disabling neurological disease, which has a tremendous impact on sufferers, healthcare systems, and the economy. According to the 2016 WHO report, migraine is the second leading cause of years lived with disability, greater than all other neurological diseases combined. Yet, the treatment in migraine is far from optimum; the sufferers often abuse painkillers and complicated with medication overuse headache. Migraine is characterized by the hypersensitivity of the sensory system, potentially attributed to dysfunctional pain modulatory networks located in the deep brain structures, particularly the brainstem. However, the current understanding of these deeply seated, dysregulated pain modulatory circuits in migraine is limited due to technological constraints. Besides, studies with an in-depth analysis of the clinical manifestations (i.e., deep phenotyping) are lacking, and there is no corresponding animal model readily available for translational research. In this project, the investigators propose a multimodal approach to address these issues by applying the technologies and platforms developed by our team to explore the correlation between pain sensitivity and dysregulated connectivities from brainstem to other brain regions. In this four-year project, the investigators will recruit 400 migraine patients and 200 healthy subjects. The investigators aim at decomposing the key brainstem mechanisms underlying dysmodulated pain sensitivity in migraine from 5 comprehensive perspectives: (1) clinical deep phenotyping, (2) high-resolution brainstem structural MRI and functional connectivity analysis, (3) innovative brainstem EEG signal detecting technique, (4) multimodal data fusion platform with neural network analysis, and (5) ultrahigh-resolution brainstem-based connectomes, intravital manipulations and recording, and connectome-sequencing in animal models. Moreover, the investigators will collaborate with Taiwan Semiconductor Research Institute to develop a wearable high-density EEG equipment, integrated with a System-on-Chip capable of edge-computing the signal using algorithms derived from our brainstem decoding platform. The ultimate goal is to build a real-time brainstem decoding system for clinical application.

Effectiveness of Gaze Stability Exercises on Balance and Activities of Daily Living Among Patients Suffering Vertigo With Vestibular Neuritis in Saudi Arabia

Gaze stability exercise is a medical procedure for persons with unilateral vestibular disturbances such as vestibular neuritis or persons who have had tumors of their 8th nerve. They are a crucial part of the vestibular dysfunction rehabilitation protocols in health centers. These activities which involve turning one's eyes at different angles while having their eyes focused on an optotype are aimed at helping improve the vestibular ocular reflex (VOR), visual acuity during head movements and also reducing vertigo and dizziness. Study aim: This review will be establishing the effectiveness of applying gaze stability with balance exercises procedure among participants who are suffering vertigo due to vestibular neuritis. Methods: Twenty volunteers between the age of 25-59 years old, diagnosed, and confirmed to be suffering from vestibular neuritis and vertigo will be used in this study. Gaze stability exercises will be performed while patients are in a seated position. Each exercise will last for 30 seconds and be done in phases that included; eyeball movement, saccadic eye movement, pursuit eye movement, vergence eye movement, and vestibular-ocular reflex exercise. Balance exercises will be performed in a standing position including both static and dynamic training with or without closing eyes. The following outcome measures for each participant will be assessed pre-and post-treatment after completing four weeks of intervention. They include; Arabic version of Activities-Specific Balance Confidence Scale (A-ABC scale), Arabic version of Dizziness Handicap Inventory (A-DHI), Berg Balance Scale (BBS), and Katz Index of Independence in Activities of Daily Living (Katz ADL). The findings will then be subjected to statistical methods and data analysis using the SPSS toolkit. In this study we hypothesis that practicing gaze stability and balance exercises will have a positive influence on balance and activities of daily living among vestibular neuritis patients.

Study of Wireless Nerve Stimulation in the Treatment of Chronic Migraine

The purpose of this study is to illustrate the safety and effectiveness of the StimRelieve Halo Nerve Stimulator System in the treatment of chronic migraine. The StimRelieve Halo System utilizes a minimally invasive procedure to implant a neurostimulator. This technology includes an octopolar electrode array stimulator with an embedded receiver. The energy source is a small, external, rechargeable transmitter, which is worn by the patient. The StimRelieve Halo System eliminates the implantable pulse generator, which has been the most common reason for reoperation or discomfort with existing devices. For this study, all subjects will be randomized at enrollment into either a delayed or immediate continuation group. The immediate continuation group will immediately continue with the stimulation therapy after the 30-day trial period and will be monitored for a total of 12 months. The delayed activation group will have their device turned off after the 30-day trial period for the next 3-months. At the 3-month visit, both groups be evaluated and the delayed activation group will have their devices reactivated. All subjects will immediately receive the permanent stimulator(s). The permanent stimulators can easily be removed if non-responders are identified. The wireless technology eliminates the need for externalized extensions, IPG's and thus reoperation. Additionally the outcome is highly dependent on placement of the stimulators. By eliminating the need for a staged trial, infection rates and incidence of pocket pain will decrease. In this study, subjects will undergo a 30-day trial in order to demonstrate effectiveness. Immediate activation of all devices will be done in the post-op period based on sensory response and subject comfort. Subjects will be seen at 14-days post-implant to assess patient compliance with the device, assess clinical response and to adjust programming parameters if not responding. Subjects will be seen at 1 month post-implant and headache diaries and questionnaires will be reviewed. Subjects not responding to the therapy by at least a 30% reduction in headache days will be deemed non-responders and will be withdrawn from the study and can choose to have the device removed. After the trial period, all responders will follow their random assignment determined at enrollment (delayed or immediate continuation). All subjects will be monitored for a total of 13 months. Adverse events will be monitored throughout the study.
