Detailed Description
Background:
Alzheimer's disease (AD) is a common dementia in elderly populations, and amnestic mild cognitive impairment (aMCI) refers to a transitional stage between normal aging and early dementia. Patients with aMCI are at higher risks of evolving toward AD. Although it has been widely recognized that early intervention of aMCI holds the potential to delay or even reverse the cognitive impairment, no treatment is available yet. Episodic memory dysfunction is the characteristic impairment in aMCI, cognitive control training significantly improved executive function in patients with aMCI . Whether and how cognitive control training improves episodic memory function in patients with aMCI remains largely unknown.
Objectives:
The primary objective of this double-blinded, randomized RCT is to assess whether internet-based cognitive control training in patients with amnestic Mild Cognitive Impairment improves their episodic memory function. The second objective is to evaluate the effect of cognitive control training on neural plasticity, including brain activation and white matter integrity, which are assessed by functional and structural MRI.
Patients and Methods:
The proposed study is a single-center, double-blinded, randomized controlled trial that will include 70 patients diagnosed with aMCI from the neurology clinics at The First Affiliated Hospital, Zhejiang University. The patients will be randomized to either a training or a control group. The intervention is internet-based cognitive control training performed for 30 minutes over 60 sessions. Neuropsychological assessment and functional magnetic resonance imaging (MRI) will be performed before and 12 weeks after training.
Relevance:
Currently there is no known treatment available for aMCI. The proposed study is to determine the efficacy of cognitive control training on episodic memory function in patients with aMCI. Secondly, using functional and structural MRI, this study is to reveal the potential mechanism underlying cognitive control training.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Active Comparator: training group
Intervention: Internet-based adaptive cognitive control training program.
5 x 30 minutes per week, for 12 weeks.
|
The cognitive training will be an internet-based adaptive cognitive control training program, specific training paradigms include Flanker, 1-back, 2-back.
To maintain task difficulty, the tasks will be grouped based on the task difficulty.
Furthermore, each task will have various difficulty levels.
|
Placebo Comparator: control group
Intervention: placebo program: a fixed, primary difficulty level task.
5 x 30 minutes per week, for 12 weeks.
|
For the control group, a fixed, primary difficulty level program for all participants is set.
