About this study

Official title: Effects of Training Dose on Computerized Cognitive Training in People With Cognitive Impairment: A Large-population Retrospective Study

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.

Read the 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.

Computerized cognitive training with different training doses

Cognitive Dysfunction, Dementia

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Computerized cognitive training with different training dosesOther

    The training dose was defined as training frequency (number of training days per week) and average training duration per training day. The daily dose was divided into 13 categories with an interval of 5 minutes and the training frequency has 7 categories according to the number of training days per week.

Study groupRoleWhat they receive
Patients with cognitive impairment taking computerized cognitive trainingThe exposures and outcomes were measured repeatedly during the training process for each patient. The outcomes were compared to assess the effect of different exposures (computerized cognitive training with different doses). A mixed effects model was built to solve the random effects of patients.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in cognitive abilities between the adjacent weeks

    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).

    Measured: At the end of each week through the study completion (up to 5 years)

Questions about this trial

What is this clinical trial studying?

An observational study of Cognitive Impairment, Mild and Dementia, run by Xuanwu Hospital, Beijing at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 21 May 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in cognitive abilities between the adjacent weeks (time frame: At the end of each week through the study completion (up to 5 years)). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 21 May 2024.
