“…BCI shows promise in the future of treating VD patients, specifically those who suffered from a stroke [125]. BCI technology can assist care providers to objectively assess the cognitive function of patients as well as cognitive function of patients suffering from VD [125]. One study of 14 basilar artery stroke patients showed sensorimotor rhythm neurofeedback training(SMR-NF) with BCI systems used positively affected memory functioning versus 14 patients that did not have BCI feedback [126].…”

Cognitive impairment is a condition which affects aging patient populations and is becoming more prevalent as the geriatric population expands. It is categorized by the extent of cognitive decline, memory loss, functional abilities, and the capability to perform daily tasks. Based on the degree of impairment, it is classified as mild cognitive impairment or dementia. Considering the debilitating nature of cognitive decline and its impact on quality of life, prevention is key. In addition, given the gradual progression of the underlying causes of cognitive decline, early diagnosis and appropriate management has the potential to offer clinical advantages and better patient outcomes. Management options discussed vary from pharmaceutical regimens to neurosurgical interventions, with differing outcomes based on etiology of cognitive impairment.

“…Studies have shown that more than 60% of stroke patients have cognitive dysfunction and up to 33% may progress to dementia; thus, early intervention is considered essential. [1][2][3] In real-world clinical practice, however, the management of stroke patients mainly focuses on physical symptoms, while cognitive decline is likely to be ignored. The Xingnao Kaiqiao acupuncture technique, pioneered by Academician Shi Xuemin, chooses acupoints that have the effects of activating the brain, regulating visceral function, and dredging meridians, so as to improve patient cognitive functions.…”

Objective: To investigate the therapeutic effect of Xingnao Kaiqiao acupuncture combined with modern rehabilitation therapy on cognitive dysfunction after acute ischemic stroke (AIS). Methods: Totally 140 patients with cognitive impairment after AIS admitted to Sichuan Provincial Rehabilitation Hospital from September 2016 to May 2021 were included in this prospective randomized controlled trial. After admission, patients were randomly divided into the trial group and the control group based on a computer-generated random number table. Patients in the trial group were treated with Xingnao Kaiqiao acupuncture combined with modern rehabilitation therapy, and those in the control group were treated with modern rehabilitation therapy alone. Before and after treatment, Mini-Mental State Examination (MMSE) and Barthel index (BI) were used to evaluate the cognitive function and daily living activities, and event-related potentials (ERP) were also measured in both groups. Statistical analyses were performed to compare the results between the two groups. Results: Finally 135 patients were included, 67 in the trial group and 68 in the control group. After treatment, the MMSE score and BI were significantly improved in both groups as compared with those before treatment (both P < .001). In the trial group, the BI and the MMSE subscores in the domains of orientation, registration, recall, and language were significantly higher than those in the control group (all P < 0.05). The global MMSE score of the trial group was higher than that of the control group both after 2 and 4 weeks of treatment, and the differences were statistically significant (P = 0.000/0.001). In the analysis of time effect alone, time had significant effects on the MMSE score in both groups (P < 0.001). After treatment, the latencies of P3 waves were significantly shorter and the amplitudes of P3 waves were significantly higher in the trial group as compared with the control group (both P < 0.05). Conclusion: Xingnao Kaiqiao acupuncture combined with modern rehabilitation therapy may be associated with a better efficacy in treating cognitive dysfunction after AIS. The effect of Xingnao Kaiqiao acupuncture on ERP may play a role in the mechanism underlying such a therapeutic effect.

“…Recent studies have shown the effectiveness of applying BCI using mental practice in motor recovery for subacute and chronic stroke patients with hemiparesis (6,(11)(12)(13)(14)(15)(16)(17)(18)(19). Furthermore, a relevant rehabilitation study combing BCI and mental practice showed promising results for the recovery of cognitive skills (executive functions, language, memory, attention, and visuospatial skills) in post-stroke patients (20).…”

BackgroundWe investigated the effects of brain-computer interface (BCI) combined with mental practice (MP) and occupational therapy (OT) on performance in activities of daily living (ADL) in stroke survivors.MethodsParticipants were randomized into two groups: experimental (n = 23, BCI controlling a hand exoskeleton combined with MP and OT) and control (n = 21, OT). Subjects were assessed with the functional independence measure (FIM), motor activity log (MAL), amount of use (MAL-AOM), and quality of movement (MAL-QOM). The box and blocks test (BBT) and the Jebsen hand functional test (JHFT) were used for the primary outcome of performance in ADL, while the Fugl-Meyer Assessment was used for the secondary outcome. Exoskeleton activation and the degree of motor imagery (measured as event-related desynchronization) were assessed in the experimental group. For the BCI, the EEG electrodes were placed on the regions of FC3, C3, CP3, FC4, C4, and CP4, according to the international 10–20 EEG system. The exoskeleton was placed on the affected hand. MP was based on functional tasks. OT consisted of ADL training, muscle mobilization, reaching tasks, manipulation and prehension, mirror therapy, and high-frequency therapeutic vibration. The protocol lasted 1 h, five times a week, for 2 weeks.ResultsThere was a difference between baseline and post-intervention analysis for the experimental group in all evaluations: FIM (p = 0.001, d = 0.56), MAL-AOM (p = 0.001, d = 0.83), MAL-QOM (p = 0.006, d = 0.84), BBT (p = 0.004, d = 0.40), and JHFT (p = 0.001, d = 0.45). Within the experimental group, post-intervention improvements were detected in the degree of motor imagery (p < 0.001) and the amount of exoskeleton activations (p < 0.001). For the control group, differences were detected for MAL-AOM (p = 0.001, d = 0.72), MAL-QOM (p = 0.013, d = 0.50), and BBT (p = 0.005, d = 0.23). Notably, the effect sizes were larger for the experimental group. No differences were detected between groups at post-intervention.ConclusionBCI combined with MP and OT is a promising tool for promoting sensorimotor recovery of the upper limb and functional independence in subacute post-stroke survivors.
