“…17,45 Therefore, cognitive deficits present in individuals with MCI may not be severe enough to be detected by resting-state EEG recordings. As previous research has shown associations between event-related potentials (ERPs) and cognitive function in individuals with MCI, 46 future studies should consider using ERPs. Furthermore, the small sample size of this study may have limited finding consistent correlations and warrants bigger trials in the future.…”

Aim The aim of this pilot study was to examine the acute effect of a psychomotor intervention (PMI) on auditory‐verbal memory, emotional state, and electrocortical activity recorded by electroencephalography on subjectively healthy older adults (sHE) and older adults diagnosed with mild cognitive impairment (MCIs). Methods Eleven MCIs and 11 sHE underwent a single 45‐min PMI. Resting state electroencephalography, the Rey Auditory‐Verbal Learning Test, MoodMeter®, and the Positive and Negative Affect Schedule were compared between groups and pre‐ and post‐PMI. Results Electroencephalography current source density and activity within the theta frequency band were higher in MCIs than in sHE at baseline, and brain frequency had a tendency to decrease in MCIs after training. Both groups showed improvement on the auditory‐verbal memory test. Only among MCIs were there increases in perceived physical state and psychological strain and an improvement in negative affect. Conclusions Our findings suggest that acute psychomotor activity may be more effective for MCIs than for sHE. It supports the notion that PMI does have functional influences on the central nervous level and therefore might prevent and treat cognitive, psychological, and psychiatric symptoms of people with mild cognitive impairment.

“…While ERPs’ sensitivity in differentiating individuals with SCD and MCI remains less known, early evidence indicates similar brain alterations between these two groups [ 17 ]. SCD can be related to disorders other than AD, such as psychiatric diseases, and individual diagnostic workups may help reveal underlying causes [ 18 ].…”

Subjective cognitive decline (SCD) and mild cognitive impairment (MCI) are early stages of Alzheimer’s disease (AD). Neurophysiological markers such as electroencephalography (EEG) and event-related potential (ERP) are emerging as alternatives to traditional molecular and imaging markers. This paper aimed to review the literature on EEG and ERP markers in individuals with SCD. We analysed 30 studies that met our criteria, with 17 focusing on resting-state or cognitive task EEG, 11 on ERPs, and two on both EEG and ERP parameters. Typical spectral changes were indicative of EEG rhythm slowing and were associated with faster clinical progression, lower education levels, and abnormal cerebrospinal fluid biomarkers profiles. Some studies found no difference in ERP components between SCD subjects, controls, or MCI, while others reported lower amplitudes in the SCD group compared to controls. Further research is needed to explore the prognostic value of EEG and ERP in relation to molecular markers in individuals with SCD.

Background: Intermittent theta burst stimulation (iTBS) is known to improve cognitive impairment caused by Alzheimer's disease and Parkinson's disease, but studies are lacking with respect to the efficacy of iTBS on poststroke cognitive impairment (PSCI).Objective: This study was conducted to investigate the effect of left dorsolateral prefrontal cortex (DLPFC) iTBS on improving cognitive function in stroke patients.Methods: Fifty-eight patients with PSCI are randomly divided into iTBS (n = 28) and sham stimulation groups (n = 30). Both groups receive routine cognitive-related rehabilitation. The iTBS group is treated with iTBS intervention of the left DLPFC, and the sham stimulation group is treated with the same parameters at the same site for 2 weeks. Outcome measures are assessed at baseline (T0) and immediately after the last intervention (T1) by mini-mental state examination (MMSE), Oxford cognitive screen, and event-related potential P300.Results: There are no differences in baseline clinical characteristics between the two groups. After intervention, the MMSE scores and P300 amplitude increase significantly for both groups, and the P300 incubation period reduces significantly. The change value of the iTBS group is significantly higher than that of sham stimulation group (p < .05). Compared with the sham stimulation group, the iTBS group has more significant changes in semantic comprehension and executive function (p < .05). Conclusion: iTBS can effectively and safely improve overall cognitive impairment in stroke patients, including semantic understanding and executive function, and it also has a positive impact on memory function. Future randomized controlled studies with large samples and long-term follow-up should be conducted to further validate the results of the present study K E Y W O R D S cognitive disorder, double-blind randomized controlled trial, intermittent theta burst stimulation, stroke This is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited.
