Jiangxi's First Robot-Assisted Brain-Computer Interface Surgery for Drug-Refractory Epilepsy

Background

Drug-refractory epilepsy refers to cases where seizures cannot be adequately controlled with medication. Precise identification of the brain regions generating seizures is essential for potential surgical treatment. Traditional stereoelectroencephalography (SEEG) monitoring often requires patients to remain hospitalized with wired equipment for extended periods, which can be inconvenient and limit natural seizure triggers during daily life. Brain-computer interface (BCI) technology connects the brain directly to external devices to record and interpret neural signals.

In July 2025, The First Affiliated Hospital of Nanchang University in Jiangxi Province completed the province's first robot-assisted brain-computer interface SEEG surgery. The procedure was performed as a clinical research-type operation on a 26-year-old female patient who had lived with epilepsy for 15 years. This marked an advance in the hospital's neurosurgery capabilities for neurological disorders.

What was achieved

The neurosurgery team, including Director Li Meihua and Deputy Director Lu Guohui, successfully implanted electrodes within the patient's cranium. This established a bidirectional neural interaction channel between the brain and external equipment. The BCI system enabled real-time monitoring and intelligent algorithmic decoding of abnormal electrical discharges in the epileptic regions while the patient could move freely with a portable external device.

This was reported as Jiangxi's first such integration of robot assistance with BCI technology for SEEG in drug-refractory epilepsy. It demonstrated the feasibility of shifting epilepsy diagnostics from experience-based to more data-driven precise approaches. The hospital indicated this was the initial step, with the first two components of BCI (signal recording and decoding) implemented in this case.

How it works

In robot-assisted SEEG, a surgical robot aids in planning and guiding the precise insertion of multiple thin electrode leads through small openings in the skull. These leads are positioned in targeted brain areas suspected of originating seizures, based on pre-operative imaging. The robot enhances accuracy, minimizes tissue disruption, and supports minimally invasive placement compared to traditional frame-based methods.

Once implanted, the BCI component records the brain's electrical signals. These signals are transmitted to an external portable unit that the patient wears. Algorithms process the data to decode patterns of abnormal activity associated with epilepsy. Sources describe the general BCI process in four stages: recording brain electrical signals, decoding them with algorithms, using the decoded information to control a device or provide intervention, and feeding information back to the user. In this surgery, the focus was on achieving reliable recording and real-time intelligent decoding, allowing doctors to better localize foci without confining the patient to a hospital bed.

What it means for international patients

The First Affiliated Hospital of Nanchang University maintains an International Medical Center for VIP and foreign patients. This department coordinates care for international visitors, and the hospital has experience in international medical cooperation. As a designated National Regional Medical Center for Neurological Diseases with growing expertise in advanced BCI and robotic neurosurgical techniques, it could be relevant for patients exploring options in functional neurosurgery or epilepsy management.

International patients considering such innovative procedures should directly contact the hospital to verify current availability, determine personal eligibility, and obtain detailed medical assessment. These initial BCI applications were conducted in a clinical research context, and suitability depends on individual medical history and hospital protocols. No specific information on outcomes for non-Chinese patients was reported.
