New implant could track seizures for months
NCT ID NCT04526418
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study tested a small device implanted under the scalp to record brain waves (EEG) continuously for up to 12 weeks in people with epilepsy. The goal was to see if it could detect seizures better than standard short-term hospital monitoring and patient diaries. The trial involved 64 adults with temporal lobe epilepsy and compared the device's recordings to video-EEG in the hospital and seizure logs at home.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
24/7 EEG™ SubQ system (implanted device)
What this could lead to
If successful, this device could provide a more accurate and convenient way to track seizures over long periods, potentially improving epilepsy management.
What could go wrong
The trial was terminated early, so results are limited. The device is still experimental, and its accuracy and safety compared to standard monitoring are not fully established.
