NCT ID NCT07570251
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether cognitive education activities could help breast cancer patients who experience memory, attention, and thinking problems after chemotherapy, often called 'chemobrain'. 108 patients took part. The activities were designed to support memory, attention, and executive function. The goal was to see if these exercises could improve cognitive function, reduce depression, and help with odor recognition.
