Brain zaps and treadmills: new hope for 'Chemo Brain'?
NCT ID NCT07587957
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests if a 4-week program combining exercise with a gentle, non-invasive brain stimulation technique (tACS) can help breast cancer survivors who struggle with memory and focus after treatment. Researchers will check if the program is practical and safe for 40 participants, and measure any improvements in thinking and physical function compared to a placebo group.
