August 14, 2020 updated by: Binyin Li, Ruijin Hospital

Shanghai Non-pharmacological Intervention of Mild Cognitive Impairment for Delaying Progress With Longitudinal Evaluation

This study evaluates the effects of "computerized cognitive training" and "cognitive training plus exercise training" on different cognitive domains in mild cognitive impairment (MCI) patients. Patients will be randomized into the computerized training group, cognitive training plus exercise training group and the control group.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Unknown

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Mild cognitive impairment (MCI) is an early stage of Alzheimer Disease (AD). Increasing evidence has indicated that cognitive trainings improve cognition functions of MCI patients in multiple cognitive domains, making it a promising therapy for MCI. However, the effect of long-time training has not been widely explored. It is also necessary to evaluate the extent of its function in reducing the conversion rate from MCI to AD.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

50 years to 85 years (Adult, Older Adult)

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: online cognitive training
Patients will receive 3-4 times of 20-30 minutes' training game every week
Behavioral: Online cognitive training
A variety of cognitive domains will be involved in the training including memory, calculation, attention, visuospatial and executive skills. The difficulty level of each game will be adjusted automatically according to patients' last training results so that patients' correction rate will be kept between 70% and 80%.
No Intervention: no training
Patients will not undergo preoperative cognitive training.
Experimental: Cognitive training and physical exercise
Patients will receive 3-4 times of 20-30 minutes' training game every week and 2 times of 60 minutes' Tai Chi Training
Behavioral: Cognitive training plus physical exercise

Physical Exercise Tai Chi Training：a teacher will give two 60-min lessons per week. Participants will play Tai Chi in the lessons, following teacher's instruction.
