Comparative efficacy of non-pharmacological interventions for post-stroke cognitive impairment: a systematic review and network meta-analysis of randomized controlled trials.

Researchers compared different non-drug treatments to help people recover thinking and memory skills after a stroke. Many stroke survivors experience cognitive problems that affect their daily lives and independence. This study analyzed 23 clinical trials involving 1,723 stroke patients who received various treatments including computer-based brain training, brain stimulation techniques, acupuncture, exercise, and combinations of these approaches.

The researchers measured improvements using two main scales: the Montreal Cognitive Assessment (MoCA) for mental function and the Modified Barthel Index (MBI) for daily living abilities. They found that combining computer-based cognitive training with a brain stimulation method called transcranial direct current stimulation (tDCS) worked best for improving thinking skills. However, acupuncture combined with another brain stimulation technique called repetitive transcranial magnetic stimulation (rTMS) came in as a close second, showing significant cognitive improvements with scores increasing by 6.59 points compared to standard care alone.

For stroke patients considering acupuncture, these results are encouraging. Acupuncture combined with rTMS demonstrated substantial benefits for cognitive recovery after stroke, ranking among the top treatments tested. Even among standalone therapies, acupuncture showed promise as part of a comprehensive rehabilitation approach. The study suggests that combining different treatment methods may offer better results than single interventions alone.

These findings indicate that acupuncture, particularly when integrated with modern brain stimulation techniques, can be a valuable component of stroke recovery programs for improving memory, attention, and overall cognitive function. If you're considering acupuncture for post-stroke cognitive recovery, seek treatment from a licensed acupuncturist with experience in neurological rehabilitation.

This network meta-analysis evaluated seven non-pharmacological interventions for post-stroke cognitive impairment across 23 RCTs (n=1,723). Primary outcome was Montreal Cognitive Assessment (MoCA) scores; secondary outcome was Modified Barthel Index (MBI) scores. Results demonstrated that computer-based cognitive training combined with transcranial direct current stimulation (CCT+tDCS) produced the highest MoCA improvements (MD: 6.67; 95% CrI: 1.20-12.13), followed closely by acupuncture combined with repetitive transcranial magnetic stimulation (MD: 6.59; 95% CrI: 4.34-8.84). SUCRA probability rankings confirmed these combination therapies as most effective for cognitive outcomes. For functional recovery (MBI), tDCS alone (MD: 8.41; 95% CrI: 4.50-12.32), exercise rehabilitation (MD: 6.87), and CCT (MD: 6.62) demonstrated superior efficacy. No significant publication bias was detected. Clinical takeaway: Multimodal interventions combining acupuncture with neuromodulation techniques show robust evidence for PSCI management, with effect sizes comparable to leading brain stimulation protocols. Integration of acupuncture into comprehensive stroke rehabilitation protocols is supported by this high-quality evidence synthesis.
