OPM- MEG in Non-immune And iMmune-medIated Neurological Disease (O-MEG-A-MIND)

8. Juli 2026 aktualisiert von: Aston University

The "O-MEG-A-MIND" Study OPM- MEG in Non-immune And iMmune-medIated Neurological Disease

Over the past 20 years, doctors have gotten much better at spotting and treating brain conditions caused by the immune system attacking the body. These include illnesses like autoimmune encephalitis, ADEM, and multiple sclerosis. But even with better treatments, many patients-especially children-still struggle with long-term problems. Standard brain scans and tests often miss important issues like memory problems, emotional difficulties, trouble sleeping, and challenges with social behaviour. Early research using a special brain imaging technique (called MEG) has shown changes in brain networks that seem to be linked to poor memory. This study will use a new, advanced version of MEG that works even with very young children (as young as 2 years old). The goal is to better understand how these brain conditions affect children, compare them with other types of brain illness, and eventually use this technology to help predict outcomes and discover new ways to track brain health.

Detaillierte Beschreibung

This study is an 8-year cross-sectional and observational cohort study involving the use of OPM-MEG, MEG, MRI and neuropsychology testing based at the Aston Institute of Health and Neurodevelopment, Birmingham, UK. Children and young people with immune and non-immune mediated neurological disease aged 2-15 years will be recruited locally (Birmingham Children's Hospital) and from London and Manchester.

The longitudinal cohorts (n=25 in each, total n=50) will be those with immune- and non-immune mediated neurological disease within 9 months of diagnosis. They will be invited for 3 study visits (Study Visits 1, 2 and 3).

The cross-sectional cohort (n=25) will be those with immune-mediated neurological disease at least 18 months after diagnosis. They will be invited to for one study visit (Study Visit 1).

The study visits:

At Study Visit 1 (Baseline), participants will undergo OPM-MEG, MEG and MRI as well as neuropsychology testing and questionnaire completion. Total time taken is 5 hours. This visit can be split into 2 visits within a 2 week window.

At Study Visit 2 (2 years)and 3 (5 years) participants will undergo OPM-MEG, MEG and MRI and questionnaire completion. Total time taken is 3 hours.

Participants travelling from outside the West Midlands will be offered overnight accommodation for Study Visits.

The participants are welcome to have as many breaks as is necessary during each/any Study Visit. It is expected that breaks will last between 15 minutes to one hour. Refreshments will be available for the participants on the day and will ask in advance of the visit in case of any allergies. Aston University, where the IHN is based, has food outlets Tesco, Greggs and Costa Coffee available too. Another adult, aside from the research team, can be present during the research recordings.

Experimental: Cross-sectional - participants who have had a neuroimmunological condition over 18 months ago
Longitudinal - participants who are within 9 months of disease
Gerät: OPM- Magnetoencephalography

To assess the changes in brain network function that occur in relation to immune and non-immune mediated brain disease, participants will undergo OPM-MEG recording. This will be conducted at all study visits.

To assess the behavioural and functional changes following disease from the patient and caregiver perspective questionnaires will be completed on paper-based forms. These are all established outcomes measures used in our and others' previous studies in immune and non-immune mediated disease in children.

The cryogenic MEG recording will also assess changes in brain dysfunction and will be directly comparable to the advanced OPM-MEG data.

To assess the effect of disease on brain structures, participants will undergo MRI scanning at the IHN.

To assess functional outcomes of immune and non-immune mediated disease, participants will undergo neuropsychology assessments.

Change from Baseline in OPM-MEG Resting-State Delta-Band (1-4 Hz) Local Efficiency

Local efficiency of resting-state brain networks derived from OPM-MEG recordings, computed from amplitude envelope correlation connectivity matrices (Desikan-Killiany atlas parcellation) using the Brain Connectivity Toolbox, compared between participants with immune-mediated and non-immune-mediated neurological disease across proportional connectivity thresholds (10-30%).

On the WISC-V and WPPSI-IV, the theoretical minimum Full Scale IQ score is 40 and the maximum score is 160, with higher scores indicating better cognitive outcomes and stronger academic potential.

Beschreibung des IPD-Plans

Data from this cohort may be highly valuable to future research efforts. Thus, we will ask participants to provide written informed consent to make their anonymised data freely available for reanalysis by the team in future studies, and to researchers outside of the study team for use in ethically approved projects. Specifically, neuroimaging (MRI), questionnaire, neuropsychology (summary scores) and demographic data that are suitable for sharing will be made available, using open-access data repositories platforms such as OSF (osf.org) or other suitable platforms which meet current best practice within the field, in relation to local and national regulations (i.e. GDPR). Open-access sharing of data will only happen once the linking document (linking study ID to personal identifiable data i.e. name) is destroyed (3 years after study end), to ensure that shared data is truly anonymous, not pseudo-anonymised

IPD-Sharing-Zeitrahmen

3 years after study end after linking document destroyed September 2037 to September 2047
