Temporal Dynamics of Subtle Cognitive Change: Validation of a User-Friendly Multidomain Digital Assessment Using an Alcohol Challenge

Temporal Dynamics of Subtle Cognitive Change: Validation of a User-Friendly Multidomain Digital Assessment Using an Alcohol Challenge

This includes conditions with primary pathology anchored in the central nervous system (CNS—ie, neurodevelopmental, neuropsychiatric, and neurodegenerative disorders, as well as trauma), as well as CNS impairment secondary to other drivers of brain dysfunction (eg, “brain fog” following chemotherapy, chimeric antigen receptor T-cell, or radiation therapy, COVID-19).

Leveraging Cognitive and Speech Ecological Momentary Assessment in Individuals With Phenylketonuria: Development and Usability Study of Cognitive Fluctuations in a Rare Disease Population

To make sure that we understand if performance was impacted by time of day, we used t tests to compute whether there was a significant difference in performance between morning EMAs (EMAs 1 and 2), evening (EMA 3 and 6), and morning and midday EMAs (EMA 4 and 5). Finally, for baseline tasks, average performance was reported.

Longitudinal Digital Phenotyping of Multiple Sclerosis Severity Using Passively Sensed Behaviors and Ecological Momentary Assessments: Real-World Evaluation

Longitudinal Digital Phenotyping of Multiple Sclerosis Severity Using Passively Sensed Behaviors and Ecological Momentary Assessments: Real-World Evaluation

Thus, to predict the outcome at the end of the ith period at time T=i P where P=2 weeks or 4 weeks, the action feature matrix comprised features from time (i-1)P and time i P, whereas the action and context feature matrix comprised features from time (i-2)P and time i P (Figure 1). Missing sensor data could occasionally occur due to several reasons. Multimedia Appendix 1 (section A.2) describes the detailed approach for handling missing data.
