Abstract
Neurocognitive deficits post-stroke is a pervasive repercussion of stroke, adversely affecting key cognitive faculties, including executive function, memory, and attention. Transcranial Direct Current Stimulation (tDCS) is a non-intrusive technique that modulates brain activity without the need for surgical intervention. This review consolidates current literature to critically examine the effectiveness of tDCS in ameliorating cognitive deficits associated with PSCI. Although numerous studies suggest promising outcomes, particularly in augmenting executive function and overall cognition, its efficacy in enhancing memory and attentional processes remains ambiguous. Variability in stimulation protocols, patient demographics, and study methodologies further complicates the interpretation of results. Given the escalating interest in tDCS as a rehabilitative modality, a rigorous and systematic review is imperative to delineate its therapeutic value, highlight existing research gaps, and inform future investigations aimed at optimizing its clinical application in post-stroke cognitive rehabilitation.
