“…As shown previously, a successful option for multi-tasking may be a combination of motor training and attention or executive function tasks [16,31,32]. Some authors have pointed to the positive effect of their inclusion in the rehabilitation course [28][29][30]. It was also reported that these elements have a positive effect on cognitive abilities and recommend a cautious increase in task complexity, depending on the individual abilities of the subject [31].…”

“…The inclusion criteria were as follows: stable coronary artery disease (CAD), elective CABG, aged 45-75 years, and provided informed consent. The exclusion criteria were as follows: history of stroke, epilepsy, traumatic brain injury, depression, dementia; Montreal Cognitive Assessment Scale (MoCA) score ≤ 18 (30); Beck's Depression Inventory (BDI-II) score ≥ 8 (31); and noncardiovascular decompensated comorbidities [30]. All of the patients met the study criteria and signed an informed consent form.…”

“…POCD was determined for each patient individually, using the percentage of relative changes in postoperative indicators compared with a baseline using the following formula: (baseline value-postoperative value)/baseline value) × 100%. Negative values indicated an increase in the cognitive indicator compared to the baseline, positive values indicated a decrease, and the threshold value for cognitive decline was equal to 20% [30]. The examiners were standardized and unaware of the patients' participation in the study.…”

“…However, it is also very important to gradually increase the level of difficulty of a cognitive task throughout the learning process. Preliminary evidence suggests that combined motor-cognitive training can provide effective cognitive recovery in patients with cardiovascular disease, optimize cognitive and physical functions, and improve quality of life [30].…”

Background: The multi-tasking approach may be promising for cognitive rehabilitation in cardiac surgery patients due to a significant effect on attentional and executive functions. This study aimed to compare the neuropsychological changes in patients who have undergone two variants of multi-tasking training and a control group in the early postoperative period of coronary artery bypass grafting (CABG). Methods: One hundred and ten CABG patients were divided into three groups: cognitive training (CT) I (a postural balance task with mental arithmetic, verbal fluency, and divergent tasks) (n = 30), CT II (a simple visual–motor reaction with mental arithmetic, verbal fluency, and divergent tasks) (n = 40), and control (n = 40). Results: Two or more cognitive indicators improved in 93.3% of CT I patients, in 72.5% of CT II patients, and in 62.5% of control patients; CT I patients differed from CT II and control (p = 0.04 and p = 0.008, respectively). The improving short-term memory and attention was found more frequently in the CT I group as compared to control (56.7% vs. 15%; p = 0.0005). The cognitive improvement of all domains (psychomotor and executive functions, attention, and short-term memory) was also revealed in CT I patients more frequently than CT II (46.7% vs. 20%; p = 0.02) and control (46.7% vs. 5%; p = 0.0005). Conclusions: The CT I multi-tasking training was more effective at improving the cognitive performance in cardiac surgery patients as compared to CT II training and standard post-surgery management. The findings of this study will be helpful for future studies involving multi-tasking training.

Background: There is growing interest in finding methods to enhance cognitive function and comprehend the neurophysiological mechanisms that underlie these improvements. It is assumed that non-pharmacological interventions have better results in cognitive recovery. The aim of this study was to assess the effect of multi-task cognitive training (MTT) on electroencephalographic (EEG) changes and markers of the neurovascular unit in patients undergoing coronary artery bypass grafting (CABG). Methods: This prospective cohort study involved 62 CABG patients aged 45–75 years, 30 of whom underwent a 5–7-day MTT course. The groups of patients were comparable with respect to baseline clinical and anamnestic characteristics. An EEG study was performed before surgery and 11–12 days after CABG. Markers of the neurovascular unit (S100β, NSE, and BDNF) were examined at three time points: before surgery, within the first 24 h after surgery, and 11–12 days after CABG. Results: Patients without training demonstrated higher relative theta power changes compared to the MTT patients. The course of MTT was associated with low plasma S100β concentration but high BDNF levels at the end of the training course. Conclusions: The theta activity changes and the markers of the neurovascular unit (S100β, BDNF) indicated that the severity of brain damage in cardiac surgery patients after a short course of MTT was slightly reduced. Electrical brain activity indicators and vascular markers can be informative for monitoring the process of cognitive rehabilitation in cardiac surgery patients.

Aim. To compare the incidence of postoperative cognitive dysfunction and neuropsychological changes in the early postoperative period of coronary artery bypass grafting (CABG) in patients who underwent two versions of multitask cognitive training, which involved various cognitive and motor tasks, as well as in a control group.Material and methods. The study included 100 patients after elective CABG. All patients were randomly divided into three following groups: cognitive training (CT) 1 (postural balance combined with mental arithmetic, verbal fluency, and unusual object use tasks) (n=30), CT 2 (simple visual-motor response combined with task on mental arithmetic, verbal fluency and unusual object use) (n=35) and without training (standard postoperative therapy) (n=35). All patients underwent extensive neuropsychological testing before CABG. Reexamination with assessment of postoperative cognitive dysfunction (POCD) was carried out on days 2-3 and upon completion of 5-7 days of training or on days 11-12 after CABG.Results. The presence of POCD on days 2-3 was found in 100% of patients in the study groups. On days 11-12 of CABG, POCD persisted in 17 people (56,7%) from the CT 1 group, in 24 (68,6%) from the CT 2 group, and in 28 (80%) patients in the control group. Significant differences were obtained in the POCD prevalence in the CT 1 and control groups (odds ratio =3,06; 95% confidence interval: 1,02-9,18, p=0,04), but not CT 2 and control groups (odds ratio =1,83; 95% confidence interval: 0,64-5,47, p=0,28).Conclusion. Multitask training using a combination of postural balance and mental arithmetic tasks, verbal fluency, and unusual object use had a greater effect in reducing the POCD incidence in patients after CABG compared with standard postoperative care. The results of this study may be used to develop cognitive rehabilitation programs in cardiology and cardiac surgery.
