Brief Summary:
The purpose of this study is to integrate advanced computational techniques and multimodal neuroimaging methods to examine the potential effects of long-term, multi-domain, online, computerized cognitive training on large-scale structural and functional brain networks in older adults with mild cognitive impairment (MCI).

Condition or disease Intervention/treatment Phase
Mild Cognitive Impairment Behavioral: Multi-domain cognitive training Behavioral: Cross-word puzzle training Not Applicable

Detailed Description:
This multilevel study will be comprised of a placebo controlled randomized controlled trial to test the effect of long-term (6 months), multi-domain, computerized cognitive training on large-scale structural and functional brain networks in individuals with MCI (age >= 65 years). Neuroimaging and neuropsychological data before and after intervention will be evaluated within and between groups to elucidate the trajectory of neuronal network improvements associated with training compared to typical MCI development. We will compare the outcomes between participants with MCI who receive structured cognitive training (treatment group: TG) with those who receive nonspecific computerized training activities (active controls: AC). The duration of intervention is 6 months. The focus of the study will be on individuals with amnestic MCI (single- or multi- domain). The study includes 30 MCI subjects in a treatment group (TG) and 30 matched MCI subjects in active control (AC) group. TG and AC participants will be evaluated at two time points: 1) baseline and 2) 6-month (post-training).

Arm Intervention/treatment
Experimental: Treatment
Treatment group will receive 6 months of online, computerized, multi-domain cognitive training at home.
Behavioral: Multi-domain cognitive training
The cognitive exercises are designed to train executive functions and memory.

Active Comparator: Active Control
The Active Control group will receive 6 months of online, computerized cross-word puzzles at home using the same platform as for the Treatment group.
Behavioral: Cross-word puzzle training
The active control group will be asked to complete a variety of crossword puzzles using the same curriculum assigned to the TG group.

Primary Outcome Measures :
  1. Executive function composite score [ Time Frame: 6 months ]
    The primary behavioral outcome is executive function composite score that combines measures of working memory, inhibition, set-shifting, and fluency

  2. Executive function network connectivity [ Time Frame: 6 months ]
    The primary neuroimaging outcome is the interconnectivity of the frontal-striatal-parietal network.

Secondary Outcome Measures :
  1. Memory function composite score [ Time Frame: 6 months ]
    Memory function composite score that combines measures of auditory verbal learning and episodic memory

  2. Medial temporal network connectivity [ Time Frame: 6 months ]
    Regional interconnectivity and centrality in medial temporal network

  3. White matter integrity in memory circuit [ Time Frame: 6 months ]
    White matter integrity in posterior cingulate-medial temporal-frontal pathways
