Burden of Mild Cognitive Impairment among the Elderly in India: A Systematic Review and Meta-Analysis.

Random-effects models were used to calculate pooled prevalence with 95% confidence intervals (CIs), stratified by community- and hospital-based settings.

Higher prevalence was observed among individuals with type 2 diabetes (53%), hypertension (57%), and those undergoing hemodialysis (38%).

Diagnostic tool choice significantly influenced prevalence, with MoCA-based assessments yielding higher estimates than MMSE or Petersen criteria.

Substantial heterogeneity was present across studies (I² >96%).
