Computerized Cognitive Training for MCI

19 mars 2019 uppdaterad av: Huali Wang, Peking University

A Randomized Control Trial on Computerized Cognitive Training for Individuals With Mild Cognitive Impairment

The objective of the study is to evaluate whether memory training combined with executive training could lead to improved cognitive and noncognitive performance in patients with MCI. Furthermore, we will explore the neural correlates underlying the changed performances.

Detaljerad beskrivning

Introduction:

Mild cognitive impairment (MCI) is a clinical condition characterized of a reduction in memory and/or other cognitive processes that are insufficiently severe to be diagnosed as dementia, but are more pronounced than the cognitive decline associated with normal aging. The prevalence of MCI ranges from 3% to 19% in adults older than 65 years; some of these individuals seem to remain stable or return to normal over time, but more than half progress to dementia within 5 years. Thus, MCI represents a critical window of opportunity for intervening and altering the trajectory of both cognitive decline and loss of functional independence in older adults. Cognitive function apart from memory such as executive function is also impaired in patients with MCI. However, no study has yet placed sufficient emphasis on the training of executive function.

Objectives:

The objective of the study is to evaluate whether memory training combined with executive training could lead to improved cognitive and noncognitive performance in patients with MCI. Furthermore, we will explore the neural correlates underlying the changed performances.

Patients and Methods:

The proposed study is a single blinded, randomized and controlled trial that will include 120 elderly patients with MCI from the memory clinic. The groups will be randomized to either intervention or waiting-list group. The intervention is computerized combined memory and executive function training performed for 60 minutes x 4 times/week over 26 weeks. A neuropsychological assessment will be administered at baseline and week 4, 12 and 26 after the intervention. The structural and functional MRI, EEG and NIRS will be performed at baseline and week 26 after intervention for a sub-study on the effect of cognitive training on brain structure and function.

Vapen och interventioner

Deltagargrupp / Arm
Intervention / Behandling
Experimentell: Combined cognitive training
The training is combined executive function and memory training. The training is considered 'adaptive', which means that the difficulty level of the tasks increases during the sessions according to the individual level of mastering for each participant, making the patient work at their maximum capacity at all times.
Enhet: Combined executive function and memory training
Computerized combined executive function and memory training
Inget ingripande: Waiting-list group
Participants in the control condition will conduct the same training as the intervention group after a 26-week waiting period. During the 26-week waiting period, the participants will receive assessment with the same protocol as the interventional group.
