Summary

This study explores whether an Apple Watch can track walking, heart rate, breathing, and sleep in people with glioblastoma, a serious brain cancer. The goal is to see if the watch can detect symptom changes before they become serious, like seizures or blood clots. Twenty-five patients will wear the watch and report symptoms over six months.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: Apple Watch (wearable device)
What this could lead to: If successful, this could lead to tools that predict complications like seizures or blood clots in glioblastoma patients before they happen.
What could go wrong: This is a small, early study with only 25 participants and is currently suspended. The Apple Watch may not reliably detect changes, and results may not apply to all patients.
