Brief Summary:
Effective, clinically meaningful treatments are lacking for patients with mild cognitive impairment (MCI), which is associated with increased risk of transition to dementia. Cognitive training represents an important therapeutic strategy. In a previous study, crossword puzzles were found to be superior to computerized cognitive training on the primary cognitive outcome and function with decreased brain atrophy. Building on these findings, this study will evaluate and compare the impact of high dose crosswords (4 puzzles per week) to low dose crosswords (1 puzzle per week) and a health education control group on the cognition and function of participants.
Detailed Description:
This study plans to enroll 240 participants with MCI: 75 at Columbia University, 60 at Duke, 60 at University of Miami, 45 at University of Washington. Participants will be randomized 1:1:1 to 4 crossword puzzles per week (high dose arm), 1 crossword puzzle per week (low dose arm), or health education (control arm). In the crossword groups, this initial intensive 12-week phase will be followed by booster sessions that will each comprise 30-minute sessions (1 or 4 sessions depending on assignment) completed over 1 week, and occur at weeks 20, 32, 42, 52, 64, and 78. In-person assessments will occur at 0, 12, 32, 52, 78 weeks. During weeks 0, 12, 32, 52, and 78, participants in the 4/week crosswords group will complete three sessions at home and the fourth in clinic, and participants in the 1/week group will complete one session in the clinic and none at home. During weeks 20, 42, and 64, participants will complete all sessions at home. The health education group will receive in-person sessions and assessments at weeks 0, 12, 32, 52, and 78 weeks, each for 30 min (same time frame as the crossword groups), and phone calls will be made, each for 30 min, at weeks 20, 42 and 64 to match the crossword groups (each 30 min). Unique features of the design: Evaluation of home-based crossword puzzles as the primary intervention; Comparison of two dose conditions to a comparison group; Health education comparison group with readings to mimic placebo in clinical trials; Stratification of random assignment by site, age, and early MCI/late MCI; Evaluation of MRI atrophy indices and plasma biomarkers of neurodegeneration (Neurofilament Light, Nfl) and Alzheimer Disease pathology (ptau-217).
