Deep electrodes may outperform subdural grids in epilepsy localisation

Better outcomes at one year

Stereoelectroencephalography (SEEG) appears to be more versatile and have better procedural morbidity than subdural electrode (SDE) implantation for identifying the source of seizures in patients with intractable epilepsy, a US study suggests.

Procedures are used to identify the source of seizures in epilepsy

More patients had favourable epilepsy outcomes at one year if they underwent evaluation using SEEG (76%) compared with SDE (54.6%), according to the study published in JAMA Neurology.
