Identification of Volatile Organic Compounds (VOCs) as Biopredictors of Epileptic Seizures
Living with epilepsy can be stressful due to unpredictable seizures. This study aims to find specific smells, known as 'volatile organic compounds' (VOCs), that people release before, during, and after an epileptic seizure. Researchers believe that if we can identify these unique smells, it could lead to the development of a non-invasive device to predict seizures. This would allow people to take preventative measures, avoid accidents, and improve their quality of life by potentially reducing anxiety and even allowing some to drive. The study also considers different types of seizures and the challenges of differentiating them from non-epileptic events. Ultimately, understanding these smells could pave the way for a small, electronic device, similar to an 'electronic nose,' to give early warnings.
At a glance
What is this study about?
Imagine being able to know when an epileptic seizure is about to happen. This study is exploring a really exciting idea: whether our bodies release distinctive smells, called 'volatile organic compounds' or VOCs, just before, during, or after a seizure. Think of it like a unique scent signature that only appears when a seizure is near. We already know that certain specially trained dogs can actually sniff out seizures, sometimes even before they start, which suggests these smells exist. This research wants to pinpoint exactly what these specific seizure-related smells are.
Why is this so important? For people with epilepsy, the uncertainty of seizures can be incredibly stressful and really affect their daily lives. If engineers could identify these specific smells, they could develop a device, like a small electronic 'nose,' that would detect them and give an early warning. This could mean people could take their medication on time, avoid dangerous activities like driving, or even prepare themselves to prevent injuries. It could make a huge difference to their independence and how safe and calm they feel.
Currently, there isn't a device that can reliably predict seizures. While some devices can detect a seizure once it's happening, this study focuses on prediction – giving a head start. By understanding these subtle changes in body scent, scientists hope to build a non-invasive tool that is easy to use and could improve the quality of life for many people living with epilepsy. The study will also look at different types of seizures and how individual factors like age or medication might affect these smells.
Key takeaways
- The study looks for specific body smells linked to epilepsy.
- These smells could help create a seizure prediction device.
- It aims to make life safer and less stressful for people with epilepsy.
- Participation involves collecting scent samples in hospital; it's non-invasive.
- This is early research, not a direct treatment.
Who may be eligible?
To be considered for this study, you need to be at least 18 years old and have a specific type of epilepsy that hasn't responded well to medication (this is called 'drug-resistant epilepsy' by doctors). You must experience one of three particular kinds of seizures: focal seizures, focal seizures that spread, or generalised seizures (which can be motor or non-motor).
You would also need to be staying in a hospital for at least 48 hours for a special recording called a video-EEG. This helps doctors monitor your brain and body activity. Lastly, you'll need to give your permission to join the study and be part of the UK social security system.
You wouldn't be able to join if you are pregnant or breastfeeding, or if you have certain legal arrangements beyond a basic power of attorney (like a deputyship or guardianship). The study aims to gather very specific information, so these criteria help ensure the results are as clear and accurate as possible.
Could this study suit you?
Answer these quick questions to see if you may be eligible. This is a guide only — the research team makes the final call.
- Are you 18 years old or older?
- Do you have epilepsy that hasn't responded well to medication?
- Do you experience focal or generalised seizures?
- Are you scheduled for at least 48 hours of video-EEG monitoring in a hospital?
- Are you not pregnant or breastfeeding?
What does participation involve?
If you decide to take part, the main thing you'll be doing is collecting samples of your breath and skin (which is where these 'smells' are found) over several days. This will happen while you are already staying in the hospital for your video-EEG monitoring, so it shouldn't add extra hospital visits. The researchers will simply be collecting these samples at different times before, during, and after any seizures you might have, as well as when you are seizure-free.
There won't be any new medications for this study, and you'll continue with your usual epilepsy treatment. The focus is purely on collecting the scent samples. The total duration of your participation will be limited to your stay for the video-EEG monitoring, which must be at least 48 hours.

Common questions
What are 'volatile organic compounds'?
These are tiny molecules released by your body that have a smell, even if you can't always detect it yourself.
How will the smells be collected?
Researchers will collect samples of your breath and from your skin, likely using simple, non-invasive methods, while you are in hospital.
Will this study help me personally?
Not directly. This is early research to understand if seizure smells exist, which could help future patients.
What is 'drug-resistant epilepsy'?
This means your epilepsy has not been well-controlled by at least two different epilepsy medications.
Do I need to do anything differently if I join?
No, you just continue with your usual medical care and the samples will be collected during your hospital stay for monitoring.
