EEG-Guided Cognitive Function Preservation in Patients With Brain Tumors

9. juli 2026 opdateret af: Bo Wang

A Prospective Single-Arm Study of EEG-Based Neural Signal Decoding for Cognitive Function Preservation in Patients Undergoing Brain Tumor Surgery

Brain tumors and their surgical treatment may impair cognitive function, affecting patients' quality of life. This prospective single-arm study aims to evaluate the feasibility and clinical utility of an EEG-based neural signal decoding strategy for cognitive function preservation in patients undergoing brain tumor surgery. Participants will undergo standardized neuropsychological assessments together with preoperative, intraoperative, and postoperative electrophysiological recordings. The study will investigate whether EEG-based neural decoding can improve objective cognitive function assessment and support individualized functional preservation during brain tumor surgery.

Detaljeret beskrivelse

This is a prospective, single-center, single-arm interventional study designed to investigate an EEG-based neural signal decoding strategy for higher-order cognitive function preservation in patients undergoing brain tumor surgery.

Eligible patients with brain tumors scheduled for surgical treatment will be enrolled. Participants will receive standardized neuropsychological assessments before and after surgery. High-density EEG recordings will be acquired during different stages of the perioperative period, including task-based and resting-state paradigms when applicable. Neural signal decoding methods will be used to extract cognitive-related electrophysiological features and evaluate their association with postoperative cognitive outcomes.

The primary objective is to evaluate the feasibility of EEG-based neural signal decoding for objective cognitive assessment and functional preservation during brain tumor surgery. Secondary objectives include exploring the relationship between electrophysiological biomarkers and neuropsychological performance, evaluating perioperative cognitive changes, and providing preliminary evidence for individualized cognitive protection strategies in brain tumor patients.

Våben og indgreb

Deltagergruppe / Arm
Intervention / Behandling
Eksperimentel: EEG-Guided Cognitive Function Preservation
Participants undergoing brain tumor surgery will receive the EEG-based neural signal decoding strategy in addition to standard surgical management for individualized cognitive function preservation. Cognitive outcomes will be evaluated using standardized neuropsychological assessments.
Procedure: EEG-Based Neural Signal Decoding Strategy
EEG-based neural signal decoding will be performed during the perioperative period to identify cognitive functional networks and assist individualized cognitive function preservation during brain tumor surgery.
