RESUMO
OBJECTIVE: To systematically assess the effectiveness of transcranial direct current stimulation (tDCS) on global cognition in patients with mild cognitive impairment (MCI) and Alzheimer's disease (AD). DATA SOURCES: Ten databases were retrieved for pertinent Chinese and English studies published up until February 2023. DATA EXTRACTION: Two researchers independently selected the literature, extracted the data, evaluated using the Cochrane Collaboration's quality criteria, and then cross-checked. Meta-analysis was performed using RevMan 5.4. RESULTS: 22 studies involving 1074 patients were included. Compared with the control group received the interventions such as pharmacotherapy, cognitive stimulation, et al., with/without sham-tDCS, while the experiment group received tDCS added to the interventions of the control group. The meta-analysis found that tDCS increased MMSE, MoCA, MODA scores and reduced the P300 latency scores (all P < 0.05). CONCLUSION: The tDCS can ameliorate the global cognition of patients with MCI and AD, and it has a better rehabilitation effect than non-tDCS or sham-tDCS.
RESUMO
OBJECTIVE: To systematically evaluate the impact of high-frequency repetitive transcranial magnetic stimulation (HF-rTMS) on activities of daily living (ADLs) of patients with post-stroke cognitive impairment (PSCI). DATA SOURCES: Relevant studies published as of November 2022 (English and Chinese) were searched in Web of Science, PubMed, Embase, Cochrane Library, OVID, China Science and Technology Journal Database (VIP), Wanfang, Chinese National Knowledge Infrastructure (CNKI), and SinoMed databases. REVIEW METHODS: Randomized controlled trials (RCTs) that used HF-rTMS for the treatment of ADLs in patients with PSCI were included in this meta-analysis. Two reviewers independently screened literature, extracted the data, evaluated the risk of bias using the Cochrane Risk of Bias Tool, and cross-checked. RESULTS: Forty-one RCTs involving 2855 patients with PSCI were included. In 30 RCTs, the experimental group received HF-rTMS in addition to the interventions used in the control group. In 11 RCTs, the experimental group received HF-rTMS while the control group received sham-rTMS. Barthel Index (BI), Modified Barthel Index (MBI), and Functional Independence Measure (FIM) were higher in the HF-rTMS group than in the control group, whereas scores of Blessed Behavior Scale was lower in the HF-rTMS group than in the control group. All P < 0.05. In 36 studies, the stimulation sites were on the dorsolateral prefrontal cortex (DLPFC). CONCLUSION: HF-rTMS can ameliorate ADLs of patients with PSCI and has a better rehabilitation effect on PSCI.

BACKGROUND: Post-stroke cognitive impairment (PSCI) imposes a huge burden on patients and society as a whole; however, unequivocally effective treatments for PSCI are still lacking. Therefore, the exploration of effective and safe non-pharmacological treatment modalities for PSCI is a key imperative. Moxibustion has been widely used for cognitive rehabilitation; however, there is a paucity of systematic reviews of the available evidence. Therefore, we conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) that investigated the effectiveness of moxibustion for treatment of PSCI to provide evidence base for the treatment of PSCI with moxibustion. OBJECTIVE: To evaluate the efficacy of moxibustion in improving cognitive function and activities of daily living (ADLs) in patients with PSCI. DESIGN: Systematic review and meta-analysis of RCTs. PARTICIPANTS: Patients with a clinical diagnosis of PSCI. REVIEW METHODS: Relevant studies published in English or Chinese were retrieved from ten databases until December 2021. RCTs that assessed the efficacy of moxibustion on cognitive functioning and ADL in patients with PSCI were included. Two reviewers independently identified the trials and extracted the data. Risk-of-bias was assessed using the Cochrane Risk of Bias Tool. Cochrane's Review Manager (RevMan 5.4) software was used for the meta-analysis. RESULTS: Eighteen RCTs (1290 participants) qualified the inclusion criteria and were included. Compared with the control group, the addition of moxibustion significantly improved the cognitive function, evaluated using the Montreal Cognitive Assessment (MoCA) [pooled mean difference (MD): 2.27, 95% CI: 1.98, 2.55, I2 = 22%]. The pooled MD of Mini-Mental State Examination (MMSE) score was 1.85 (95% CI: 1.56, 2.15, I2 = 26%), and the pooled odds ratios (OR) total effective rate was 4.74 (95% CI: 2.55, 8.80, I2 = 0%) (p < 0.05 for all). Moxibustion also significantly improved ADL, assessed using Modified Barthel Index (MBI) (pooled MD = 4.10, 95% CI: 2.10 to 6.10, I2 = 0%) and Barthel Index (pooled MD: 8.63, 95% CI: 7.47, 9.79, I2 = 5%) (p < 0.05 for all). CONCLUSIONS: Compared with control group, the addition of moxibustion significantly improved the cognition and ADL of patients with PSCI. CLINICAL RELEVANCE: Nurses can incorporate moxibustion into the rehabilitation nursing of PSCI.

OBJECTIVE: Survivors of stroke often experience post-stroke sleep disorders (PSSDs), but pharmacotherapy risks adverse side effects. Transcranial magnetic stimulation (TMS) is potentially a nonpharmacotherapeutic option. This meta-analysis investigated the effects of rTMS to treat PSSD. METHODS: Databases were searched for randomized controlled trials (RCTs) of rTMS to treat PSSD, conducted in accordance with the PRISMA 2020 guidelines. Risk-of-bias assessments were performed using the Cochrane risk-of-bias tool. A meta-analysis of the following indexes was performed using RevMan 5.4 software: Pittsburgh sleep quality index; effective rate of sleep improvement; Hamilton Anxiety Rating Scale (for mood); and National Institute of Health Stroke Scale (NIHSS, stroke severity). Mean differences (MDs) and confidence intervals (CIs) were calculated. RESULTS: The meta-analysis included 17 RCTs, with 1411 patients overall. The indexes indicated that rTMS could improve the sleep quality, mood, and stroke severity of patients with PSSD: Pittsburgh sleep quality index (12 studies; MD = - 2.51, 95% CI [- 3.24, - 1.79], P < 0.00001); effective rate of sleep improvement (7 studies; MD = 4.03, 95% CI [2.43, 6.68], P < 0.0001); Hamilton Anxiety Rating Scale (2 studies; MD = - 4.05, 95% CI [- 4.77, - 3.32], P < 0.00001); and NIHSS (2 studies; MD = -2.71, 95% CI [- 3.36, - 2.06], P < 0.00001). CONCLUSION: The results suggest that rTMS may have positive effects on the sleep quality, mood, and stroke severity of patients with PSSD.

OBJECTIVE: To systematically research the impact of warming needle moxibustion (WNM) for Alzheimer's Disease (AD). METHODS: Four Chinese databases and six English databases were systematically searched. Randomized controlled trials (RCTs) involving the use of WNM to intervene in AD patients were included. Data were extracted from the included studies and methodological quality was evaluated according to the Cochrane Handbook for Systematic Reviews of Intervention 5.1.0. Meta-analysis was performed using RevMan 5.4 software. RESULTS: 8 RCTs comprising 524 patients were included. Most studies had no significant bias. The study showed that WNM was more effective in the treatment of AD than acupuncture or pharmacotherapy. The findings were as follows: MMSE (MD = 1.01, 95%CI: 0.13, 1.90, P = 0.03) and CDR (MD = -0.73, 95%CI: -0.84, -0.61, P < 0.00001) for global cognitive function, ADL (MD = -1.84, 95%CI: -2.47, -1.22, P < 0.00001) for activities of daily living, Syndrome Differentiation Scale of Dementia (SDSD) (MD = -2.67, 95%CI: -3.62, -1.72, P < 0.00001), and the total effective rate of patients (OR = 3.20, 95%CI: 1.90 to 5.38, P < 0.0001). The differences in all indicators were statistically significant. CONCLUSION: WNM might have a significant effect on improving cognitive function and daily living ability, reducing the symptoms of AD, and increase the total effective rate. WNM is an effective non-pharmacological therapy for patients with AD.

OBJECTIVE: The aim of the study is to determine the efficacy of transcranial direct current stimulation on global cognition and ability in daily life activities of patients with poststroke cognitive impairment. DESIGN: Nine electronic databases were searched from their respective inceptions through January 2022. We included the randomized controlled trials that used transcranial direct current stimulation for poststroke cognitive impairment and included at least one global cognitive function or ability in daily life activities outcome indicators. Two reviewers appraised the risks of bias through the Cochrane Collaboration's tool and performed the meta-analysis. We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 guidelines. RESULTS: Twenty-two studies (1198 participants) were included. Most studies had no significant bias in the quality of the methodology. Meta-analyses found that compared with the control group, transcranial direct current stimulation increased Montreal cognitive assessment, Mini-mental state examination, Loewenstein occupational therapy cognitive assessment, total effective rate of cognition, modified Barthel Index, and decreased P300 latency (all P < 0.05). These results showed transcranial direct current stimulation can improve cognitive function and ability in daily life activities in poststroke cognitive impairment. CONCLUSIONS: The transcranial direct current stimulation may have a significant rehabilitation effect on global cognitive functioning and ability in daily life activities of patients with poststroke cognitive impairment.
