BACKGROUND: Digital biomarkers offer promising avenues for enhancing the identification, prognosis, and phenotyping of Alzheimer’s Disease (AD). This study evaluates the feasibility and utility of the MIND GamePack©, a digital game platform designed to measure leisure cognitive activity over time.
METHODS: Gameplay data were collected from 60 participants across two cohorts over 3–6 months: Cohort I (no cognitive complaints) and Cohort II (subjective complaints, mild cognitive impairment, mild dementia). Analyses focused on compliance, correlation with validated neuropsychological instruments (Montreal Cognitive Assessment [MoCA], Repeatable Battery for the Assessment of Neuropsychological Status [RBANS], and Trail Making Test [TMT]), test-retest reliability, and known groups comparison.
RESULTS: The MIND GamePack© displayed high compliance and excellent test-retest reliability within 1 week (ICC=0.81–0.95) for most selected features. Several game features displayed moderate to strong correlations with standardized neuropsychological test performance. Features related to memory tasks across select games (Normalized Accuracy and Normalized Redundant Move Variability of Memory Match and Word Repetition Rate of Word Scramble) exhibited significant associations with RBANS Sum of Index Score, TMT Part A, and MoCA, respectively. Participants without cognitive impairment exhibited improvement in features over 3 months compared to those with cognitive impairment. Baseline game features differentiated cognitively normal [CN] from cognitively impaired [CI] participants across nearly all domains after controlling for age, sex, and education (p<.01).
CONCLUSIONS: The MIND GamePack© offers a sensitive, engaging approach to cognitive monitoring and screening, with potential use for dense tracking in longitudinal research and interventional clinical trials.
