“…Finally, while our analysis looked at memory performance enhanced by tDCS, a topic with potential therapeutic relevance, clinical outcomes were not the key focus of this review. Previous reviews provide some information on this topic (e.g., Hsu et al, 2015; Summers, Kang, & Cauraugh, 2016), with at least one other related systematic review ongoing (Zhang, Liu, Li, Zhang, & Qu, 2018) in the field.…”

Abstract. There is growing interest in the study of transcranial direct current stimulation (tDCS), a non-invasive brain stimulation technique, as an effective intervention to improve memory. In order to evaluate the relative efficacy of tDCS based on the location of anodal electrode sites, we conducted a systematic review examining the effect of stimulation applied during encoding on subsequent verbal episodic memory in healthy adults. We performed a network meta-analysis of 20 studies (23 experiments) with N = 978 participants. Left ventrolateral prefrontal and temporo-parietal sites appeared most likely to enhance episodic memory, although any significant effects were based on findings from single studies only. We did not find evidence for verbal retrieval enhancement of tDCS versus sham stimulation where the effect was based on more than one experimental paper. More frequent replication efforts and stricter reporting standards may improve the quality of evidence and allow more precise estimation of population-level effects of tDCS.
