Researchers at York University’s Faculty of Health found that just 30 minutes of visually-guided movements per week can slow and even reverse the progress of dementia. Those in the early stages of dementia who were exposed to 30 minutes a week to a game which used rules to make visually-guided movements, were able to slow down the progress of dementia and for some, even reverse their cognitive function to healthy status.
Previous approaches have used cognitive training alone or aerobic exercise training alone. This study published in Dementia and Geriatric Disorders, is the first to investigate the impact of combining both types of approaches on cognitive function in elderly people with various degrees of cognitive defects.
“We found cognitive-motor integration training slows down the progress of dementia, and for those just showing symptoms of dementia, this training can actually revert them back to healthy status, stabilizing them functionally,” says lead researcher, Lauren Sergio, professor in the School of Kinesiology and Health Science and Centre for Vision Research at York University.
In the intervention study, a total of 37 elderly people located at senior centres, were divided into four groups based on their level of cognition. They completed a 16-week cognitive-motor training program that consisted of training sessions involving playing a videogame that required goal-directed hand movements on a computer tablet for 30 minutes a week. Before and after the training program, all participants completed a series of tests to establish their level of cognition and visuomotor skills. Sergio’s team performed tests to evaluate cognitive function 14 days prior to and after the intervention period, respectively. Her team observed an overall change in all groups and, specifically, a significant improvement in measures of overall cognition in the sub average cognition group and the mild-to-moderate cognitive deficits group. “These results suggest that even in the earliest stages of neurodegeneration, the aging brain has enough neuroplasticity left that if you can train it on this kind of thinking and moving task, it will improve their cognitive skills,” says Sergio. “The brain still possesses the functional capacities to form sufficient new synaptic connections to induce relevant changes on a systems level.”
Sergio adds the findings suggest that repetitive cognitive-motor integration training may in fact strengthen the involved neural networks and improve cognitive and functional abilities. Researchers believe the frontal lobe is ‘talking’ to the motor control areas and this is what is paving the way for success.
The study further found that those in the severe cognitive deficits group who did 30 minutes of this eye-hand task did not decline in their cognitive deficits as expected, but instead stayed the same.
“Generally, you expect someone with severe dementia to have their cognitive function decline over five months, but in our study, they all stabilized.”
Sergio says the findings show promise for those who have early-stage dementia because the approach is easy to administer remotely and shows more promise than the basic cognitive training.

Thinking-While-Moving Exercises May Improve Cognition in Elderly with Mild Cognitive Deficits: A Proof-of-Principle Study
Background: Noninvasive interventions to aid healthy cognitive aging are considered an important healthcare priority. Traditional approaches typically focus on cognitive training or aerobic exercise training. In the current study, we investigate the effect of exercises that directly combine cognitive and motor functions on visuomotor skills and general cognition in elderly with various degrees of cognitive deficits.
Subjects and Methods: A total of 37 elderly, divided into four groups based on their level of cognition, completed a 16-week cognitive-motor training program. The weekly training sessions consisted of playing a videogame requiring goal-directed hand movements on a computer tablet for 30 minutes. Before and after the training program, all participants completed a test battery to establish their level of cognition and visuomotor skills.
Results: We observed an overall change in visuomotor behavior in all groups, as participants completed the tasks faster but less accurately. More importantly, we observed a significant improvement in measures of overall cognition in the subaverage cognition group and the mild-to-moderate cognitive deficits group.
Conclusion: Our findings indicate that (1) cognitive-motor exercises induce improved test scores, which is most prominent in elderly with only mild cognitive deficits, and (2) cognitive-motor exercises induce altered visuomotor behavior and slight improvements in measures of general cognition.
