Comparison of the telephone-Montreal Cognitive Assessment (T-MoCA) and Telephone Interview for Cognitive Status (TICS) as screening tests for early Alzheimer's disease.

INTRODUCTION: Remote screening for cognitive impairment associated with Alzheimer's disease (AD) has grown in importance with the expected rise in prevalence of AD in an aging population and with new potential treatment options. METHODS: The Telephone Interview for Cognitive Status (TICS) and new telephone adaptation of the Montreal Cognitive Assessment (T-MoCA) were administered to participants independently classified through in-person clinical evaluation as cognitively normal (CN; n = 167), mild cognitive impairment (MCI; n = 25), or dementia (n = 23). Cerebrospinal fluid AD biomarkers were measured (n = 79). RESULTS: TICS and T-MoCA were highly correlated (r = 0.787; P < 0.001): groups differed on both (CN

A survey of smartphone and interactive video technology use by participants in Alzheimer's disease research: Implications for remote cognitive assessment.

INTRODUCTION: Participants from a longitudinal cohort study were surveyed to evaluate the practical feasibility of remote cognitive assessment. METHODS: All active participants/informants at the University of California San Diego Alzheimer's Disease Research Center were invited to complete a nine-question survey assessing technology access/use and willingness to do cognitive testing remotely. RESULTS: Three hundred sixty-nine of 450 potential participants/informants (82%) completed the survey. Overall, internet access (88%), device ownership (77%), and willingness to do cognitive testing remotely (72%) were high. Device access was higher among those with normal cognition (85%) or cognitive impairment (85%) than those with dementia (52%), as was willingness to do remote cognitive testing (84%, 74%, 39%, respectively). Latinos were less likely than non-Latinos to have internet or device access but were comparable in willingness to do remote testing. DISCUSSION: Remote cognitive assessment using interactive video technology is a practicable option for nondemented participants in longitudinal studies; however, additional resources will be required to ensure representative participation of Latinos.
