Comparative effectiveness of various nonpharmacological interventions, including traditional Chinese medicine-based interventions for cancer-related cognitive impairment: a comprehensive network meta-analysis.

If you or someone you love has gone through cancer treatment, you may have noticed changes in memory, concentration, or mental sharpness. This is called cancer-related cognitive impairment — sometimes nicknamed 'chemo brain' — and it's one of the most common and frustrating side effects of cancer and its treatments.

A major new study published in the Journal of the National Cancer Institute looked at 84 clinical trials and compared 15 different non-drug approaches to help people think more clearly after cancer treatment. Researchers wanted to know which therapies worked best — and importantly, they included traditional Chinese medicine (TCM) practices like Tai Chi, Qigong, and acupoint stimulation (a category that includes acupuncture and acupressure).

The results were encouraging for fans of TCM. Tai Chi and Qigong came out on top for helping people feel subjectively sharper — meaning patients themselves reported meaningful improvements in how their minds felt day to day. That's a big deal, because how you personally experience cognitive changes matters enormously to quality of life.

Acupoint stimulation — which includes acupuncture and acupressure techniques — ranked as the best intervention for improving visuospatial and motor function, which involves skills like coordination, spatial awareness, and physical control. These are areas that can be significantly affected by certain cancer treatments.

Cognitive rehabilitation therapy led the pack for overall objective cognitive testing, executive function, and language skills.

Perhaps most reassuringly, none of the 15 interventions studied reported significant adverse events, meaning these approaches were considered safe for cancer patients.

For patients exploring complementary options alongside conventional cancer care, this research suggests that practices like Tai Chi, Qigong, and acupuncture may offer real, measurable cognitive benefits. If you're interested in trying acupoint stimulation or TCM-based therapies, seek out a licensed acupuncturist or TCM practitioner with experience working with oncology patients.

This comprehensive network meta-analysis (NMA) published in JNCI evaluated 84 RCTs encompassing 15 nonpharmacological interventions for cancer-related cognitive impairment (CRCI) in adults with non-CNS cancers. Notably, it is the first NMA to incorporate TCM-based interventions in this context. Databases searched included PubMed, Embase, ProQuest, Scopus, and CNKI through May 2024; a random-effects model was applied.

Key findings: Tai Chi/Qigong demonstrated superior efficacy for subjective cognitive function (SMD = 2.10, 95% CI: 0.62–3.59). Cognitive rehabilitation ranked highest for overall objective cognitive function (SMD = 1.49, 95% CI: 0.41–2.58), executive function, and language domains. Acupoint stimulation was the top-ranked intervention for visuospatial and motor function (SUCRA 84.3%, SMD = 0.94, 95% CI: 0.13–1.76). No significant adverse events were reported across any intervention.

Clinical takeaway: Acupoint stimulation and Tai Chi/Qigong represent evidence-supported, low-risk adjunct options for addressing specific CRCI domains in oncology patients.
