How OPM-MEG could transform epilepsy diagnosis for young people like Sam

Samuel is a pupil at Young Epilepsy’s St Piers School & College in Lingfield. In many ways, he’s a typical teenager—he loves sports, watching TV, and spending time hiding away in his bedroom. But Sam’s journey has been far from typical.

At just four years old, Sam was diagnosed with epilepsy. His mum, Tracy, recalls the sudden and distressing change in her son:

At the age of three, he went from being a very able child, who was starting to read, to someone who regressed very quickly. As a childcare professional, I could tell that his behaviour was unusual, but it still took us a long time to get anyone to listen properly to our concerns.

Eventually, Sam’s epilepsy was confirmed through an EEG—on his fourth birthday. Tracy recalls the experience as challenging: 

It was very unsettling for Sam and getting him to sit still with wires on his head was incredibly difficult. We managed only 20 minutes instead of the full hour, and the data was incomplete. We were told, ‘He has epilepsy—don’t leave him alone, don’t go swimming, don’t do this, don’t do that.’ It was a harsh introduction.

Epilepsy diagnosis often takes place in clinical, hospital-based environments that can be intimidating and restrictive—especially for children like Sam who struggle to stay still. 

While Sam did not have access to OPM-MEG, his story helps illustrate how this technology could dramatically improve the diagnostic experience for children like him.

A new kind of brain scan

OPM-MEG (Optically Pumped Magnetoencephalography) is a revolutionary brain imaging technology that could transform how epilepsy is diagnosed. Unlike traditional EEGs or MEG scans, OPM-MEG is wearable, child-friendly, and allows for natural movement during the scan. It’s not yet available to the general public, but its potential is already clear.

Tracy imagines how different Sam’s experience could have been:

With the new MEG, it’s going to be more of a family-friendly environment, where you can bring your favourite toys and your siblings along. Sam’s older brother really struggled to understand what was happening—it was scary for him too. Making the process feel more normal would be a huge help for families like ours.

For Sam, who already wears a protective helmet, the transition to an OPM-MEG helmet would be seamless. And because he loves to move, the freedom to do so during a scan could dramatically improve the quality of the data collected.

At our first EEG, we could only hold Sam still for 20 minutes, which meant the data was incomplete. We still don’t have an exact diagnosis. Knowledge is power—if this technology can pick up more information about our child’s condition, it can help us understand it more. And as a parent, you want to understand more so you can do more to help.

Even with challenges, EEGs remain an essential tool for diagnosis. Their importance is highlighted when used alongside newer technologies like OPM-MEG.

Why we need your support

Sam’s experience shows us what families currently face—and how much better things could be with OPM-MEG. His story is not just about the past, but a vision for a better future. But to make this technology widely available, we need your help. At Young Epilepsy, we’re working hard to bring OPM-MEG into clinical use, but research and development require funding.

By supporting our campaign, you can help us build a future where children like Sam receive faster, more accurate diagnoses—and ultimately, better targeted treatments that could help them become seizure-free.

Together, we can transform the future of epilepsy diagnosis and treatment.
