Effects of Training Dose on Computerized Cognitive Training in Patients

Status Completed

Clinical Trial 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.

Clinical Trial 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. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
