Overview
Brief Summary
The goal of this observational study is to explore the optimal dose of computerized cognitive training in patients with cognitive impairment. The main questions it aims to answer are:
- Is there an optimal dose of computerized cognitive training for patients with cognitive impairment?
- Is the optimal dose different in patients in different age populations? Participants enrolled in the study took a reported computerized cognitive training program and the training data were analyzed for exploring the optimal dose.
The researchers will compare the different dose groups to see if there is an optimal dose for the highest improvement in cognitive abilities.
The researchers will additionally compare two age groups (aged younger than 60y or aged 60y and older) to see if the optimal doses in the two groups are different.
Detailed Description
Background: Computerized Cognitive Training (CCT) is a form of digital therapeutics that uses computerized cognitive tasks to train patients with cognitive impairment caused by various neurological or psychiatric diseases. CCT has been shown to slow the progression of cognitive impairment in early-stage dementia, particularly in working memory. However, there is a lack of research on the optimal training dose for people with cognitive impairment. Previous meta-analyses have explored the types, delivery methods, and training dose of cognitive training in healthy older adults and those with dementia risk factors, but not in those with cognitive impairment. Objectives: The study aimed to explore the dose-response relationship of CCT and estimate the optimal daily and weekly dose for people with cognitive impairment. Participants and methods: the study is a retrospective cohort study and will enroll 21845 patients with cognitive impairment. The exposures in the study are different doses of cognitive training in a week and the outcome is the improvement in cognitive abilities in a week. The weeks with the same training dose of different patients will be classified into one group of exposure. The mixed effects model will be used to estimate the optimal dose.

Outcomes
Primary Outcomes
Change in cognitive abilities between the adjacent weeks
Time Frame: At the end of each week through the study completion (up to 5 years)
Cognitive ability is measured on the final day of training each week. The cognitive ability throughout a week is calculated based on the overall performance of cognitive training. The overall training performance is an averaged performance integrating the performance of all cognitive training tasks targeting different cognitive domains (e.g., thinking, memory, perception, attention, executive function). The performance of a certain training task is standardized according to normative scores from 0 to 100. Change in cognitive abilities is quantified as the disparity of cognitive abilities between the adjacent weeks (the measurement will be executed everyweek repeatedly).
