Methods Patients with ischemic stroke/TIA received MoCA and MMSE at baseline within 14 days after stroke/TIA, at 3 lusmn;6 months and 1-year follow-ups. The scores of MoCA and MMSE were considered to have declined if there were a reduction of -2 points in the respective scores measured across two time points. The decline in neuropsychological diagnosis transitional status was defined by a category transition from no cognitive impairment or any cognitive impairment to a more severe cognitive impairment or dementia. Results 275 patients with a mean age of 59.8 lusmn; 11.6 years, and education of 7.7 lusmn; 4.3 years completed all the assessments at baseline, 3 lusmn;6 months and 1-year follow-ups. A decline in MoCA scores from 3 lusmn;6 months to 1 year was associated with higher risk of decline in diagnosis transitional status (odd ratio = 3.21, p = 0.004) in the same time period whereas there was no association with a decline in MMSE scores. Conclusions The decline in MoCA scores from 3 lusmn;6 months to 1 year after stroke/TIA has three times higher risk for decline in the diagnosis transitional status. The decline of MoCA scores (reduction > 2points) is associated with the decline in neuropsychological diagnosis transitional status. © 2017 Tan et al.
