What does this research mean for the field?

Among non-pharmacological interventions for mild-to-moderate Alzheimer's disease, dual-task training and transcranial direct current stimulation (tDCS) are most effective for improving global cognitive screening outcomes, while repetitive transcranial magnetic stimulation (rTMS) provides the greatest benefit for ADAS-Cog scores. Novelty: ClaimNovelty.SYNTHESIS. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

To evaluate and rank the comparative cognitive efficacy of various non-pharmacological interventions in individuals diagnosed with mild-to-moderate Alzheimer's disease.

Overview

Network meta-analysis reveals dual-task training and non-invasive brain stimulation improve cognition in mild-to-moderate Alzheimer's disease, highlighting targeted non-drug therapy benefits.

Key Points

To evaluate and rank the comparative cognitive efficacy of various non-pharmacological interventions in individuals diagnosed with mild-to-moderate Alzheimer's disease.
Systematic review and Bayesian network meta-analysis of 50 randomized controlled trials (N=2856) across 11 intervention categories searched up to May 2026.
Primary cognitive outcomes included the Mini-Mental State Examination (MMSE), Montreal Cognitive Assessment (MoCA), and Alzheimer's Disease Assessment Scale–Cognitive Subscale (ADAS-Cog).
Analyses were performed in R using gemtc with surface under the cumulative ranking curve (SUCRA) metrics, alongside Cochrane risk of bias and GRADEpro certainty evaluations.
Dual-task training ranked first for global cognitive screening measures, achieving the highest cumulative probability for MMSE (SUCRA = 88.84%) and MoCA (SUCRA = 90.67%).
Transcranial direct current stimulation (tDCS) demonstrated favorable cognitive rankings on MMSE (SUCRA = 85.69%) and MoCA (SUCRA = 75.63%).
Repetitive transcranial magnetic stimulation (rTMS) ranked highest for ADAS-Cog (SUCRA = 85.22%) and was the only non-pharmacological intervention showing significant cognitive improvement compared with usual care.
