MC: Mini-Cog; MMC: modified Mini-Cog; SST: serial subtraction task; MPT: multistep performance task; DSRS: Dementia Severity Rating Scale. Neurological diagnosis: (20.6%), (6.3%), and (1.6%). Out of 21 literate participants, those with no diagnosis of neurological disease were 18 (85.7%) and those with diagnosis of neurological disease (stroke: 2, traumatic brain injury: 1) were 3 (14.3%). There were no significant differences () on any variables between two (with neurological and without neurological) groups.
