HMSE: Hindi Mental Status Examination (indicates level of cognitive function; highest score possible = 31). EASI: Everyday Abilities Scale for India (indicates level of functional disability, highest score possible = 12). P values calculated by unpaired t-test++, chi-square test*, and Fisher’s exact test+.
