Detailed Description
This study is a 6-week randomized controlled trial, conducted at Xinzhuang Town, Minhang District, Shanghai, China.
All participants (control and intervention group) complete the data collection. Demographic data will be collected before intervention including age, sex, education, marriage, etc. A comprehensive cognitive assessment and MRI will be done before and 6 weeks after the intervention respectively. Data will be collected by self-report, home visit, or telephone visit.
The intervention group receive four intervention components including cognitive training, physical exercise, healthy lifestyle intervention, and computerized cognitive training. The intervention includes group and individual sessions. Participants will be divided into 3 groups to accept the sessions successively, and each group has a monitor regarded as the communication bridge between participants and teachers as well as remind participants to attend the training and do homework in time. The training sessions (once times per week, 90 min per session, 6 weeks) referred to the schedule. The group sessions with educational content on cognitive training, healthy lifestyle intervention, and physical exercise, the detail include memory methods and strategies, attention training, brain function development which belong to cognitive training, nutrition recommendation, sleep guidance, and emotional regulation which belong to lifestyle intervention, and the session also include parts of physical exercise such as gymnastics by finger or elastic band. The intervention will be trained by general practitioners and community health workers who accepted trained before the intervention. Individual sessions consist of human-computer interaction and physical exercise. Human-computer interaction is a kind of computer program-based cognitive training guided by professional staff at the study site, conducted in 6 weeks, 3 times per week, 20-30 minutes per session, and 12 sessions. The training program is a web-based in-house developed computer program including several tasks: spatial cognition (participants regulate and merge a couple of cubes or two-dimensional figures that are exactly alike but in different directions by control handle), left and right brain balance (copy the graphics on one computer screen to another computer screen by action tracking or screen touching technology), clock (participants imitate the hour and minute hands of a clock by swinging arms and show a time as same as in the computer screen) and ATM simulation (participants withdraw cash, transfer money, check balances through operating computer similar with ATM, among which need them to remember the password and the amount of money). Individual aerobic training included activities preferred by each participant (5 times per week,30 minutes per time), such as Tai Ji, Baduanjin, elastic band gymnastics or yoga, etc. The training will be guided and supervised by trained staff.
The control group receives regular health advice weekly through brochures, home visits, or telephone calls during 6 weeks of the intervention, detail including (1) patients with cognitive impairment education: prevention from self-injury, falling injury, accidental injury, medication, lost and bad habits; (2) inmates or caregivers education; (3) cognitive impairment knowledge education; (4) prevention of cognitive dysfunction education. The intervention committee ensures that health education activities are consistent across sites and unlikely to increase physical activity.

cognitive function assessed by The Montreal Cognitive Assessment (MoCA)
Time Frame: Before the intervention
|
The MoCA is a 1-page test that measures several cognitive domains (visual perception, executive skills, language, attention, memory and orientation).
The MoCA score ranges from 0 to 30 (30 = best) and was chosen for its relatively high sensitivity for mild cognitive impairment.

MRI--T1-weighted structure imaging
Time Frame: Before the intervention
|
For the T1 MRI images, we first performed quality control using CAT12 to exclude subjects with quality scores lower than "B".
Next, we used the recon-all command of FreeSurfer 6.0.0 for brain extraction, tissue segmentation, cortical reconstruction, and brain region labeling for each subject's brain images.
We extracted the thickness, surface area, volume for cortical structures, and volume of subcortical structures in different brain regions based on the DK+Aseg parcellation template.
Finally, the brain images of each subject were nonlinearly aligned to the MNI152 template using ANTs alignment toolkit for subsequent analysis of BOLD fMRI and DWI images.

For DWI images, we mainly used the FSL toolkit for processing.
First, the b0 images of each subject were aligned with the T1 images, followed by eddy correction and head motion correction, and detection and replacement of outliers.
Next, we used the DK+Aseg parcellation template for probabilistic fiber tracking of DWI images for each subject, and finally generated a probabilistic white matter connectivity matrix for each brain region for subsequent extraction of graph theoretical metrics.

quality of life assessed by IADL
Time Frame: Before the intervention

The Lawton instrumental activities of daily living scale (IADL): IADL is an appropriate instrument to assess independent living skills.
The instrument is most useful for identifying how a person is functioning at the present time, and to identify improvement or deterioration over time.
There are eight domains of function measured with the Lawton IADL scale.
Women are scored on all 8 areas of function; historically, for men, the areas of food preparation, housekeeping, laundering are excluded.
Clients are scored according to their highest level of functioning in that category.
A summary score ranges from 0 (low function, dependent) to 8 (high function, independent) for women, and 0 through 5 for men.

Time Frame: Before the intervention

Pittsburgh sleep quality index (PSQI): Sleep quality was assessed using the Chinese version of the PSQI, which is composed of 19 items classified into seven components: subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbances, use of sleeping medication, and daytime dysfunction during the past month.
Each component is weighted from 0 to 3, generating one global score ranging from 0 to 21.
The higher score the poorer sleep quality.
