Due to the rising prevalence of Alzheimer disease and related dementias, easily deployable tools quantify risk are needed. Smartphones smartwatches enable unobtrusive continuous monitoring, but there is limited information regarding feasibility, adherence, acceptability digital data collection among racially diverse older adults. This paper examined a 4-week combined smartwatch monitoring ecological momentary assessment (EMA) study in sample A total 44 adults (aged ≥55 y) with either mild cognitive impairment or healthy cognition completed an informed consent comprehension quiz, baseline testing, training collection, questionnaires. Participants were instructed wear Garmin Vivosmart 4 for 23 h/d weeks, sync 2 smartphone apps (Garmin Labfront) daily, complete daily EMA survey automated prompts surveys charging. Training time, adherence (eg, time), response rate, performance on quiz quantified. Associations between feasibility metrics participant factors evaluated. Self-reported usability was collected at end. Consent scores high (mean 97.33%, SD 6.86% correct), sessions lasted average 17.93 (SD 6.89) minutes.

Cognitive impairments are frequently observed in subjects with severe mental illnesses (SMI), leading to a remarkable impact their real-world functioning. Well-validated and gold standard instruments available for the assessment of cognitive deficits, but different limitations should be considered, such as need specific training, lengthy administration times, practice effects, or reliance on subjective reports. Recent advances digital technologies, ecological momentary assessments (EMA), virtual reality (VR), passive phenotyping (DP), offer promising complementary approaches capturing In current mini-review, we examine research gaps that limit application these focus feasibility, reliability validity. EMA may capture functioning by increasing number evaluations throughout day, its use might hindered high participant burden missing data. Furthermore, achieve an accurate interpretation EMA, studies account sampling moment selection biases presence several confounding factors. DP faces significant ethical logistical challenges, including privacy informed consent concerns, well challenges data interpretation. VR could serve platform both more ecologically valid rehabilitation interventions, barriers include technological psychometric limitations, underdeveloped theoretical frameworks, considerations. Addressing issues is crucial ensuring novel technologies can effectively valuable complements traditional neuropsychological batteries.

Objectives: This study investigated the validity and reliability of subtle errors slowing in simple everyday tasks (Naturalistic Action Test [NAT]) to assess mild functional difficulties older adults with cognitive impairmen (MCI). Method: Older (N = 111, MAge= 73.45; SD= 6.53) classified as having healthy cognition (HC) or MCI completed neuropsychological testing two NAT (breakfast lunch) twice, separated by 4-6 wk. NATs were scored for subtle, inefficient actions (i.e., micro-errors) average time (in sec) complete a task step. Results: Participants made significantly more micro-errors [F (1, 109) 8.78, p .004, partial η2 0.07] had longer per step 13.98, < .001, 0.11] than participants HC. Micro-errors correlated tests episodic memory (r -0.237, .012) executive functioning -0.201, .035), whereas only -0.300, .0001). Test-retest was good (ICC .872, .001) moderate .675, .001). Conclusions: Measures performance familiar demonstrated strong adequate construct concurrent validity, well test-retest- inter-rater reliability, supporting their use quantifying difficulties. Future studies should explore this scoring approach develop early markers disability dementia risk.

BACKGROUND Due to increasing rates of Alzheimer’s disease and related dementias (ADRD), there is a great need for easily deployable tools quantifying risk. Digital technology such as smartphones smartwatches have ushered in new era potential monitoring ADRD due their unobtrusiveness allowance continuous data collection, but limited information regarding feasibility digital collection among older adults. OBJECTIVE This paper examines the four-week combined smartwatch (ecological momentary assessment) EMA study racially diverse sample METHODS Forty-six adults (55+) with either mild cognitive impairment (MCI) or healthy cognition completed an informed consent comprehension quiz, baseline testing, brief training questionnaires during in-person session. Then, participants were instructed wear Garmin Vivosmart4 23 hours/day four-weeks, sync two smartphone apps (Garmin, Labfront), complete daily survey. Training time, adherence survey, performance on quiz quantified. Feasibility metrics analyzed relation cognition, self-reported functional decline, demographic factors. Self-reported usability was collected at end study. RESULTS : During study, wore waking sleep hours average 20 per day 93% response rate surveys. Participants also scored well (M=97.33% correct, SD=6.86)). Older required longer times (r=.405, P=.006) who reported greater cognitive/functional decline (ECog) had lower time (r=-.387, P=.009). Those MCI (Median=20.64, IQR=2.74) significantly than those (Median=21.45, IQR=1.29; U=79.00, z=-2.048, P=.041, r=-.31). Black (Median=20.61, IQR= 3.18) White (Median=21.67, IQR=.97, U=310.00, z=3.357, p<.001).On survey all (100%) indicated they would participate future asking them over 80% agreed positive experience smartwatch. Over 90% satisfied very syncing process both apps. CONCLUSIONS Smartwatch monitoring, including syncing, highly feasible adults, strong surveys high satisfaction will require more support learning procedures time. Overall, longitudinal Labfront application acceptable collect nearly without impairment.
