Cooling helmet may shield brain from Post-Surgery mental decline
NCT ID NCT07689500
First seen Jul 08, 2026 · Last updated Jul 10, 2026 · Updated 2 times
Summary
This study tests whether wearing a cooling helmet during open-heart surgery can reduce the risk of postoperative cognitive dysfunction (POCD)—a decline in memory, attention, and thinking that sometimes follows major surgery. The helmet circulates cold water around the scalp to cool the brain, which may lower its oxygen needs and reduce inflammation. Researchers will compare outcomes in adults who receive the active cooling helmet versus a sham helmet with room-temperature water.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- Cooling helmet (non-invasive head-cooling device with cold water circulation)
- What this could lead to
- If effective, this cooling helmet could become a simple, low-cost way to protect brain function during open-heart surgery, reducing memory and thinking problems after the procedure.
- What could go wrong
- This is a single-center trial with 153 participants, so results may not apply broadly. The sham control uses room-temperature water, which may still provide some cooling, and the device may not be comfortable or practical for all patients.
