Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Head injuries are responsible for 1.4 million visits to hospital each year in the United Kingdom (UK). Most patients are allowed home the same day and make a full recovery, but some will have persistent symptoms. The investigators aim to use the latest generation of imaging technology to investigate those with mild traumatic brain injury (mTBI) to better assess them.

The investigators will invite patients presenting following trauma to the Emergency Department at Queen's Medical Centre, Nottingham, UK to participate. The investigators will compare those who have a suffered an mTBI to those who have non-head traumatic injuries. The investigators will use two magnetoencephalogram (MEG) systems and ultra-high field magnetic resonance imaging (MRI) to record the functioning and structure of the brain within days of participants' injury. The investigators will test memory and thinking skills, then follow participants for six months, record the severity of participants' symptoms, and find out who does not make a full recovery.

Multimodal imaging will consist of a standard MEG device using Superconducting Quantum Interference Device (SQUID) sensors, a novel MEG device using Optically Pumped Magnetometer (OPM) sensors and seven Tesla MRI. The investigators will test whether these innovative imaging techniques are more sensitive to the acute damage that mTBI causes than routine imaging. The investigators will also test whether early imaging can reveal who is most seriously affected, identifying those who will not recover without additional support. It is currently not clear what the predominant mechanism of damage that causes these long-term problems is and the investigators hope this study will address this.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

mTBI cases

Those diagnosed with mild traumatic brain injury (mTBI) without abnormality on standard brain structural imaging, LOC ≤30mins, amnesia for ≤24hours, GCS ≥13 at all times and recovery to GCS 15 within 24hours)

Multimodal imaging

Intervention Type OTHER

All participants will attend the Sir Peter Mansfield Imaging Centre for a scanning session using three imaging systems (SQUID MEG, OPM MEG and 7T MRI), cognitive testing and symptom questionnaires. Remote symptom monitoring and cognitive testing at three and six months.

Acute trauma controls

Non-head trauma controls matched for age and sex with the mTBI group

Multimodal imaging

Intervention Type OTHER

All participants will attend the Sir Peter Mansfield Imaging Centre for a scanning session using three imaging systems (SQUID MEG, OPM MEG and 7T MRI), cognitive testing and symptom questionnaires. Remote symptom monitoring and cognitive testing at three and six months.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Participant is willing and able to give informed consent for participation in the study
* Male or female, aged 18-35
* In the Investigator's opinion, is able and willing to comply with all study requirements.
* Willing to allow his or her General Practitioner to be notified of participation in the study
* Two groups will be recruited:

1. Diagnosed by the clinical ED team with mTBI (without abnormality on standard brain structural imaging, LOC ≤30mins, amnesia for ≤24hours, GCS ≥13 at all times and recovery to GCS 15 within 24hours)
2. Diagnosed by the clinical ED team with non-head trauma, matched for age and sex with the mTBI group.

Exclusion Criteria

* Patient requiring hospitalisation for ≥24 hours at presentation
* Any contraindication to undergo 7T MRI scan
* Pregnancy
* Other neurological, developmental or psychiatric disorders e.g. brain tumour, stroke, epilepsy, Alzheimer disease, schizophrenia, post-traumatic stress disorder, major depressive disorder, bipolar disorder or history of learning disability
* Previous hospital attendance with TBI
* Substance or alcohol abuse within six months of enrolment
* Taking certain medications thought to alter MEG signals: opioids and synthetic opioids (excluding codeine and dihydrocodeine), anti-epileptic drugs, sedatives, neuroleptics, and hypnotics
* Extensive metal dental hardware e.g. braces and large metal dentures (excluding fillings), implanted medical devices or other metal objects in the head, neck, or face areas that although they hold no risk to participants during a MEG recording may cause non-removable artefacts in the MEG data.
* Participants who have participated in another research study involving an investigational product in the past 12 weeks.
* Any other significant disease or disorder, which, in the opinion of the Investigator, may put the participants at risk because of participation in the study, or may influence the result of the study, or the participant's ability to participate in the study.
