To investigate if older populations with clinically diagnosed cognitive impairments associated with fine-motor skills difficulties could measurably benefit from a short cognitive training intervention.
38 elderly participants, half with mild cognitive impairment (MCI) and half with mild dementia (MD) completed a total of 36 sessions of NeuroTracker training. The Montreal Cognitive Assessment (MoCA) test was used to assess the baseline cognitive status, and two batteries of manual motor skills assessments completed before and after the training program.
The results showed clear and significant post-training improvements in both manual dexterity tests. Analysis indicated that only 90-minutes of NeuroTracker training was needed to achieve these benefits with these populations. The researchers concluded that this type of intervention could have a broad impact on the aging population in terms of their daily quality of life.
NeuroTracker baselines more sensitively detect effects on cognition than other cognitive assessments after open heart surgery.
To examine whether cognitive baselines can be used to detect changes in cognitive function in open-heart surgery patients.
16 open-heart surgery patients (av. 60 years) completed NeuroTracker, Montreal Cognitive Assessment, and Trails B assessments at 3 time points: 1 to 2 days pre-surgery, at discharge or 1-week post-surgery, and at 12-weeks post-surgery.
No significant differences were detected between baseline and 1-week/discharge measurements on all measures. Patients improved significantly from 1-week/discharge to 12-weeks in NeuroTracker baseline scores. A similar but non-significant trend was found on the Montreal Cognitive Assessment. The researchers concluded that post-surgical cognitive changes in heart surgery patients were detectable using NeuroTracker, and that future research should explore whether it is usable for the retraining of cognition after heart surgery.
Children undergoing cancer therapy show cognitive responsiveness to a NeuroTracker training intervention, but with effects varying with age.
To assess the feasibility of NeuroTracker training for this population and the potential cognitive effects of treatment therapy.
40 patients with CNS tumors aged 6–18 years completed 6 block of NeuroTracker training sessions.
Patients aged 10-17 years old responded well to the NeuroTracker training, improving their performance on this task by around 50%-90%. However patients under 9 years of age showed negligible improvements (atypical for subjects of this age). The results may indicate that the young children may be more cognitively sensitive to this type of antitumor therapy.
To evaluate the potential for sports vision training to improve objective and subjective visuomotor function in a low vision patient.
A 37-year-old woman with Usher syndrome underwent a 14-week sports vision training program with pre-post cognitive assessments.
The patient was able to improve the use of remaining visual abilities. A 27 to 31% improvement in hand-eye coordination was achieved along with a 41% improvement NeuroTracker performance. The patient also subjectively reported clear improvements in visual abilities. The researcher concluded sports vision training may reduce the impact of the reduced visual function and aid in activities of daily living.
A variety of egg-based diets over 1-month improve performance on NeuroTracker compared to a no-egg diet.
To evaluate the impact of the nutritional impact of dietary intake of whole eggs, egg white, and egg yolk on visual cognitive performance (NeuroTracker) in healthy older adults.
99 healthy men and women aged 50 to 75 years were randomly assigned to one of five groups with different daily consumption of eggs alongside a record of their usual dietary intake. Over 1-month period participants either consumed four egg whites, two whole regular eggs, two whole omega-3-fortified eggs, four egg yolks, or no eggs (control). During the final 2 weeks of the study all participants completed 15 NeuroTracker.
On average male participants performed significantly better at NeuroTracker than females. All participants on egg-based diets performed significantly better across 2-weeks of NeuroTracker training than the no-egg controls. Findings suggest that whole eggs, egg whites and egg yolks are beneficial for visual cognitive performance in healthy older adults.
NeuroTracker peer-reviewed research shows promising relevance for broad cognitive enhancement across different populations.
To assess the usefulness of NeuroTracker (3D-MOT) as a cognitive enhancement tool to overcome the common challenges associated with cognitive training products.
The author conducted a comprehensive review of current literature for cognitive enhancement tools, as well as the specific literature on NeuroTracker to probe its strengths and weaknesses as a research tool. Evidence was also examined for the cognitive domains that NeuroTracker addresses.
NeuroTracker was found to have broad scientific relevant for improving a number of cognitive domains, including information processing, attention, working memory, inhibition, and executive functions. Far transfer effects were found in the following human performance domains: visual information processing in healthy adults, biological motion processing in healthy aging subjects, on-field performance in soccer players, and in attention for populations with neurodevelopmental deficits. The author concluded, that while promising peer-reviewed research exists, more investigations are needed to robustly establish the beneficial effects of this method in the context of cognitive enhancement.
Perceptual cognitive training improves biological motion perception evidence for transferability of training in healthy aging
To investigate if the decline in biological motion perception associated with healthy aging can be reversed with a short NeuroTracker training intervention.
13 participants completed 3-hours of NeuroTracker training over 5-weeks, and 28 control participants did either experimental training or no training (overall mean age of 67 years old). Pre-post assessments of biological motion perception was assessed with a VR walker (point like display) at 4m and 16m.
Pre-NeuroTracker training participants displayed significantly lower performance for interpreting human movement at 4m, compared to 16m. Controls showed no change post-training, whereas the NeuroTracker trained group's performance at 4m rose to the level of their performance at 16m. As biological motion perception abilities are deemed to be important for social skills, as well as critical for collision avoidance at 4m, the researchers concluded that the results demonstrate NeuroTracker to be a useful form of generic training for helping older people deal with socially relevant dynamic scenes.
