Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Detection of group differences over time in imaging metrics using OPM-MEG.

    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%).

    Baseline (Study Visit 1), 2 years (Study Visit 2), 5 years (Study Visit 3)

Secondary Outcomes (3)

  • Change from Baseline in Whole-Brain Cortical Thickness

    Baseline, 2 years, 5 years

  • Correlation Between Resting-State Network Graph Measures and Wechsler Working Memory Index Score

    Baseline, 2 years, 5 years

  • Diagnostic/Predictive Performance of Imaging Metrics for Clinical Outcome Group (mRS-Defined)

    2 years, 5 years

Study Arms (1)

Cross-sectional - participants who have had a neuroimmunological condition over 18 months ago

EXPERIMENTAL

Longitudinal - participants who are within 9 months of disease

Device: OPM- Magnetoencephalography

Interventions

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.

Also known as: MRI, neuropsychology assessment
Cross-sectional - participants who have had a neuroimmunological condition over 18 months ago

Eligibility Criteria

Age2 Years - 16 Years
Sexall
Healthy VolunteersYes
Age GroupsChild (0-17)

You may qualify if:

  • Individuals (age range 2 yrs to 16 years) who have received a diagnosis of immune-mediated neurological disease e.g. autoimmune encephalitis1, acute disseminated encephalomyelitis, multiple sclerosis. 2
  • Individuals who have received a diagnosis of a non-immune mediated neurological disease (age range 2 yrs to 15 years 11 months) e.g. stroke.
  • Patients who can give informed consent/ assent and have a person with parental responsibility capable of giving informed consent on their behalf if aged \<16 years.

You may not qualify if:

  • There is metal in the body or any other contraindication that precludes MRI scanning at IHN, or child usually requires sedation for clinical MRI scans.
  • Participant dissents.

Data Sharing

IPD Sharing
Will share

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
