Cancer Patients Found a Simple Way to Stay Mentally Sharp During Chemotherapy
A Phase II trial involving 86 chemotherapy patients found that a home‑based exercise program (EXCAP) significantly improved attention and reduced observable cognitive lapses, outperforming placebo. Low‑dose ibuprofen also yielded modest attention gains, though it showed mixed effects on short‑term verbal memory. The study, published in *CANCER*, suggests exercise as a promising, low‑risk strategy to mitigate chemo brain, while ibuprofen’s role remains uncertain. Researchers call for larger Phase III trials to confirm these findings.
