Combined home-delivered transcranial direct current stimulation and cognitive training in older adults with mild cognitive impairment due to Alzheimer's disease: a randomized, single-blind, sham-controlled trial.
Trial report in BMC geriatrics, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT06861231 (Combined Intervention Using Transcranial Direct Current Stimulation and Cognitive Training in Alzheimer's Type Dementia Patients), which is not on this map.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

Abstract
backgroundNon-pharmacological interventions such as transcranial direct current stimulation (tDCS) and cognitive training (CT) may benefit cognition in older adults with mild cognitive impairment due to Alzheimer’s disease (MCI-AD), yet evidence on combined, home-delivered protocols remains limited. This study evaluated the effectiveness of a combined home-delivered combined tDCS and CT intervention across multiple cognitive domains in individuals with MCI-AD.
methodsWe conducted a randomized, single-blind, sham-controlled trial in 41 participants (≥ 65 years) with MCI-AD, allocated to four experimental conditions: (1) tDCS combined with CT, (2) tDCS without CT, (3) sham tDCS combined with CT, and (4) sham tDCS without CT. Interventions were delivered at participants’ homes by trained staff across 10 daily sessions. Outcomes (MMSE; TAVEC Trial 1/Total/Delayed; Forward Digit Span) were assessed at baseline, post-intervention, and 1-month follow-up. Data were analyzed with 4 × 3 mixed-design ANOVAs (group×time) with Bonferroni-adjusted post hoc tests; partial eta-squared was reported as effect size.
resultsSignificant group × time interactions were found for global cognition (MMSE), immediate memory (TAVEC Trial 1), verbal learning (TAVEC Total), and short-term memory (Forward Digit Span) (all p<.05). The combined tDCS + CT group showed sustained improvements across the significant cognitive domains at post-intervention and follow-up.
conclusionsThis randomized controlled trial provides evidence that a home-delivered combined intervention of tDCS and CT can enhance cognitive performance in older adults with MCI-AD. Improvements were domain-specific and sustained over short follow-up. While the modest sample and limited follow-up warrant cautious interpretation, the findings support the potential of combined non-pharmacological interventions delivered at home and highlight the need for larger longitudinal studies to establish their long-term efficacy and scalability.
