Brief Summary
|
Purpose of this study is it will be one of the first studies
to evaluate tDCS(transcranial direct current stimulation) in AD(Alzheimer’s Disease) patients in Odisha using a
double-blind, sham-controlled design. Addressing population-specific factors,
it provides novel insights into tDCS’s applicability in Indian contexts,
guiding future clinical and policy decisions.
Hypothesis: Active tDCS
improves cognitive function in AD patients compared to sham tDCS,
with negligible adverse effects. |
