Migraine Disorders, Brain

Researchers want to find out how a substance in the body called CGRP affects balance. CGRP (calcitonin gene-related peptide) is a small protein involved in migraine. Several approved migraine medicines work by blocking it. Studies in animals suggest that CGRP also helps a reflex called the vestibulo-ocular reflex, or VOR. The VOR keeps vision steady when the head moves: when the head turns, the eyes move the opposite way by the same amount, so the world does not appear to jump. Animals that lack the CGRP receptor have a weaker VOR. It is not known whether blocking CGRP weakens the VOR in people. This study tests whether a single dose of atogepant changes the VOR in people. Atogepant is approved in Switzerland for the prevention of migraine and blocks the CGRP receptor. In this study it is used in a different way than it is approved for. Eighty people will take part at the University Hospital Zurich. The study runs in two parts. First, 40 healthy people join. After that, 40 people who have episodic or chronic migraine join. Everyone receives both of the following, in random order: one capsule containing atogepant 60 mg one capsule containing placebo (a capsule with no active medicine) The two test visits are at least 5 days apart. A computer decides which capsule each person receives first. Neither the participants nor the study team know which capsule is which until the study is finished. At each test visit, the participant swallows the capsule at the study centre and stays for at least 90 minutes. Balance and eye-movement tests then begin, about 90 to 120 minutes after the capsule. The tests record eye movements while the head is moved quickly, while warm and cool air or water is placed in the ear canal, while a chair turns gently from side to side, and while the whole body is tilted. Participants also answer short questionnaires about nausea and dizziness before and after the tests. Each test visit lasts about 2 hours and 45 minutes. A short follow-up visit or telephone call takes place within 7 days after the second test visit. People aged 18 to 65 can take part if they have no balance disorder and meet the other study requirements. People cannot take part if, for example, they are allergic to atogepant, have taken a CGRP-blocking medicine in the past 6 months, have severe kidney or liver problems, have unstable heart disease, have a pacemaker, or are pregnant or breastfeeding. Participants are not expected to get a health benefit from taking part. The study is done to learn more about how CGRP works in the balance system, which may help in developing treatments for dizziness and migraine in the future.

Migraine is a neurological disorder associated with high levels of disability and changes in sensory processing, musculoskeletal function, and psychosocial factors. Aerobic exercise is a low-cost, non-pharmacological strategy that has shown potential benefits for migraine management, but its effects on sensory perception and musculoskeletal function are not yet fully understood. This randomized controlled trial will investigate the effects of a supervised aerobic exercise program combined with pain neuroscience education compared with an active control condition in women aged 18 to 48 years diagnosed with migraine. Participants will be randomly allocated to either an intervention group, which will perform supervised aerobic exercise three times per week for 16 weeks and receive one session of pain neuroscience education, or a control group, which will receive recommendations for unsupervised physical activity at home. Outcomes related to migraine-related disability, self-reported symptoms, sensory sensitivity, and musculoskeletal function will be assessed at baseline and after the intervention period. Questionnaires will also be collected at a 6-month follow-up. The results of this study may contribute to the development of accessible and low-risk non-pharmacological treatment strategies for people with migraine.

Using magnetoencephalography to locate and regulate targets in migraine patients, repeating transcranial magnetic stimulation to physically regulate targets, and evaluating the safety and effectiveness of this treatment method through headache related scales. Using whole genome data and scale scores for correlation analysis, and conducting randomized controls with traditional drugs to explore new approaches for migraine.
