New EEG method could sharpen brain mapping for epilepsy and tumors
NCT ID NCT04266041
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This completed study tested a high-density EEG (using up to 256 electrodes) to map brain areas involved in movement, sensation, language, and emotion. It included 122 people with epilepsy, brain tumors, or healthy controls. The goal was to see if this technique can more precisely locate seizure sources and brain functions compared to standard EEG.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- What this could lead to
- If successful, this could improve how doctors pinpoint seizure origins and map brain functions without invasive procedures.
- What could go wrong
- This is an observational diagnostic study, not a treatment trial. Results may not directly change patient care and require further validation.
