Thalamic recordings during SEEG in children with focal epilepsy
Official title: Thalamic Recordings in Children Undergoing SEEG
Run by Great Ormond Street Hospital for Children NHS Foundation Trust · NCT06453759 · Data updated 2026-11-12
This will test whether adding small electrodes into specific thalamic areas during SEEG in children with focal epilepsy can identify thalamic seizure signals to help guide future targeted treatments.

Is this trial a fit for you?
✓Likely a good fit
Children undergoing SEEG as part of their pre-surgical evaluation at Great Ormond Street Hospital whose parents or guardians provide informed consent are eligible.
✕Probably not a fit
Children who are not candidates for SEEG, who do not have thalamic involvement in their seizures, or who do not proceed to neuromodulation may not directly benefit from the recordings.

What this trial studies
SEEG is used as part of the pre-surgical evaluation to locate where seizures start, but fewer than 35% of children become seizure free after current pathways of care. This project adds recording electrodes into the bilateral anterior, centromedian and pulvinar thalamic nuclei during clinically indicated SEEG at Great Ormond Street Hospital to capture ictal and interictal thalamic activity and measure functional connectivity. The recordings are intended to map thalamic signatures of seizure involvement and to build evidence for choosing personalised thalamic targets for neuromodulation such as DBS or RNS. Participation requires informed consent and the recordings are performed alongside the child’s planned clinical SEEG procedure.
Why it matters
Potential benefit: If successful, this could help clinicians pick better thalamic targets for stimulation and potentially improve seizure outcomes for some children.
How similar studies have gone: Thalamic DBS and RNS have shown promise in some adult and mixed-age reports, but systematic thalamic recordings in children are limited, so this approach is relatively novel for the pediatric population.
