Description détaillée
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.

La description
Inclusion Criteria:
- 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.
Exclusion Criteria:
- 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.

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.

Diagnostic/Predictive Performance of Imaging Metrics for Clinical Outcome Group (mRS-Defined)
Délai: 2 years, 5 years

Correlation Between Resting-State Network Graph Measures and Wechsler Working Memory Index Score
Délai: Baseline, 2 years, 5 years
|
Association between OPM-MEG/MEG-derived delta and theta local efficiency, global efficiency, and modularity values (particularly theta modularity) and Working Memory Index composite scores from the Wechsler Intelligence Scale for Children - Fifth Edition and the Wechsler Preschool and Primary Scale of Intelligence - Fourth Edition (WISC-V/WPPSI-4), analyzed by multiple regression controlling for sex.
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.
