Can gentle movement help cancer survivors struggling with brain fog?

For many people who've survived cancer, the mental fog that lingers after treatment—trouble remembering, focusing, or thinking clearly—is one of the most frustrating parts of recovery. They're looking for ways to feel like themselves again. A new analysis pooled data from 19 studies to see if qigong, a gentle practice combining slow movement, breathing, and meditation, could help. The review found that, compared to conventional care, qigong was linked to a significant improvement in how survivors rated their own cognitive function. In other words, people who practiced qigong felt their brain fog had lifted more. The analysis included 16 studies in its main calculation, which showed a large effect. However, it's crucial to understand what this does and doesn't tell us. The improvement was in 'subjective' function—how people felt—and the review notes there's still a lack of evidence on 'objective' cognitive tests. Also, the studies included were very different from each other, which makes it hard to draw a single, firm conclusion. No safety issues were reported in the review, but the analysis didn't focus on that detail.
