Efficacy of non-invasive brain stimulation interventions on cognitive impairment: an umbrella review of meta-analyses of randomized controlled trials.

ABSTRACT:

Background

The impact of noninvasive brain stimulation (NIBS) on cognitive and mental outcomes in Alzheimer's disease (AD) and mild cognitive impairment (MCI) remains under debate due to contradictory findings from systematic reviews and meta-analyses (SRMAs). To synthesize evidence from SRMAs assessing the effectiveness of NIBS techniques on cognitive and mental outcomes in AD and MCI populations. By comparing our findings to recent reviews and clinical guidelines, we highlight how this study addresses current limitations in the literature, provides a more holistic perspective on NIBS interventions, and guides future research and clinical practice.

Methods

We searched four databases from inception to May 15, 2024, reviewing SRMAs that analyzed the effects of NIBS. Effect si
