Crossword puzzles outpace pc video video games in slowing reminiscence loss
Abstract: Crossword puzzles have a bonus over pc reminiscence video games in enhancing reminiscence perform in older adults with gentle cognitive impairment.
Supply: Columbia College
A brand new research by scientists from Columbia College and Duke College is printed within the journal NEJM Information exhibits that crossword puzzles are superior to pc video video games for reminiscence functioning in older adults with gentle cognitive impairment.
In a randomized managed trial led by DP Devanand, MD, professor of psychiatry and neuroscience at Columbia College, and Murali Doraiswamy, MD, professor of psychiatry and drugs at Duke, researchers decided that members (imply age 71 ) skilled to do web-based crossword puzzles confirmed larger cognitive enchancment than these skilled to play cognitive video video games.
“That is the primary research to doc each the short-term and long-term advantages of home-based crossword puzzles in comparison with one other intervention,” mentioned Dr. Devanand, who directs mind ageing and psychological well being analysis at Columbia College. “The outcomes are vital in mild of the difficulties in demonstrating enchancment with interventions in gentle cognitive impairment.”
Crossword puzzles are broadly used however haven’t been systematically studied in gentle cognitive impairments which might be related to a excessive danger of dementia, together with Alzheimer’s illness.
To conduct their research, Columbia and Duke researchers randomly assigned 107 members with gentle cognitive impairment (MCI) at two completely different places to both crossword puzzle coaching or intensive cognitive sport coaching for 12 weeks, adopted by as much as 78 refresher periods. weeks. Each interventions had been delivered by way of a computerized platform with weekly compliance monitoring.
Essentially the most putting conclusions of the trial had been:
- Crossword puzzles outperformed cognitive video games on the first ADAS-Cog cognitive end result measure at each 12 and 78 weeks. Crossword puzzles outperformed FAQ, a measure of day by day functioning, at 78 weeks.
- Crosswords had been higher for members within the later stage of the illness, however each types of coaching had been equally efficient within the earlier stage.
- Mind shrinkage (measured by MRI) was much less for crossbreeds at week 78.
“Advantages had been seen not solely in cognition, but in addition in day by day actions with proof of mind shrinkage on MRI, suggesting clinically related results,” mentioned Dr. Devanand.
The research additionally highlights the significance of interplay. Based mostly on distant digital monitoring of pc use, members at a later stage of the dysfunction might have carried out higher on extra acquainted crossword puzzles than on computerized cognitive video games.
Two strengths of the trial are the 28% participation of people from racial and ethnic minority teams and the low dropout price (15%) for such a protracted dwelling trial. A limitation of the research was the shortage of a management group that didn’t obtain cognitive coaching.
Though these outcomes are very encouraging, the authors emphasize the necessity for replication in a bigger managed research with an inactive management group.
“Enhancing cognition, perform and neuroprotection is the Holy Grail for this subject,” mentioned Dr. Doraiswamy. “Additional analysis on scaling mind coaching as a digital dwelling remedy to delay Alzheimer’s illness ought to be a precedence for the sphere.”

Coaching pc video games versus crossword puzzles in gentle cognitive impairment
Delicate cognitive impairment (MCI) will increase the danger of dementia. The effectiveness of cognitive coaching in sufferers with MCI is unclear.
In a single-blind, 78-week research at two websites, members with MCI—stratified by age, severity (early/late MCI), and site—had been randomly assigned to obtain 12 weeks of intensive home-based computerized coaching with Web-based cognitive video games or Web- crosswords, adopted by six additional periods. In a mixed-model evaluation, the first end result was the change from baseline within the Alzheimer’s Illness-Cognitive Evaluation Scale 11-point (ADAS-Cog), a 70-point scale by which greater scores point out larger cognitive impairment at 78 weeks, adjusted for baseline . Secondary outcomes included adjustments from baseline within the neuropsychological whole rating, the UC San Diego Efficiency-Based mostly Abilities Evaluation (useful end result), and the Useful Exercise Questionnaire evaluation (useful end result) at week 78 adjusted for baseline. Adjustments within the quantity of the hippocampus and the thickness of the cerebral cortex had been evaluated on magnetic resonance imaging.
Amongst 107 members (n=51 [games]; n=56 [crosswords]), the ADAS-Cog rating barely worsened for video games and improved for crosswords at week 78 (least squares [LS] imply distinction, −1.44; 95% confidence interval [CI], from -2.83 to -0.06; P = 0.04). From baseline to week 78, the imply ADAS-Cog rating worsened for video games (9.53 to 9.93) and improved for crossword puzzles (9.59 to eight.61). The late MCI subgroup confirmed related outcomes (LS imply distinction, −2.45; SE, 0.89; 95% CI, −4.21 to −0.70). Amongst secondary outcomes, the Useful Exercise Questionnaire rating worsened extra with video games than with crosswords at week 78 (LS imply distinction, −1.08; 95% CI, −1.97 to −0.18). Different secondary outcomes confirmed no variations. Reductions in hippocampal quantity and cortical thickness had been larger for video games than for crosswords (LS imply distinction, 34.07; SE, 17.12; 95% CI, 0.51 to 67.63 [hippocampal volume]; LS imply distinction, 0.02; SE, 0.01; 95% CI, 0.00 to 0.04 [cortical thickness]).
Residence-based computerized coaching with crosswords confirmed superior efficacy in comparison with video games for the first end result of change in baseline-adjusted ADAS-Cog rating over 78 weeks.
