Digital brain training may ease 'chemo brain' — a trial puts it to the test
NCT ID NCT07729969
First seen Jul 28, 2026 · Last updated Jul 29, 2026 · Updated 1 time
Summary
This trial tests whether two types of home-based digital cognitive training can help cancer survivors who have memory, attention, or thinking problems after chemotherapy. Participants will use either a computer program (BrainHQ) or a virtual reality cognitive training for 10 weeks. The study compares these interventions to a control group to see which approach is most effective and user-friendly.

- What this could lead to
- If effective, this could offer a convenient, home-based way to ease cognitive difficulties after cancer treatment.
- What could go wrong
- This is a relatively small, early-stage trial. The cognitive benefits may be modest or not translate to real-world improvements.
