The efficacy of Qigong exercises for post-stroke mental disorders and sleep disorders: Protocol for a systematic review and meta-analysis

High Risk Factors and Preventive Measures of Bipolar Disorder After Ischemic Stroke

Background

Bipolar disorder (BD) is a recurrent chronic disease. There are few Chinese studies to explore the BD after ischemic stroke. This study aimed to analyze the high risk factors of BD after ischemic stroke and investigate prevention strategies.

Methods

197 patients with ischemic stroke in our hospital from March 2020 to March 2022 were selected as research subjects. The demographic information, clinical data, and scores of Mood Disorder Questionnaire (MDQ) and Activity of Daily Living Scale (ADL) in patients were retrospectively analyzed to count the incidence of BD in patients. Binary logistic regression analysis was used to analyze the influencing factors for BD after ischemic stroke, and preventive measures were discussed based on study results.

Results

The incidence of BD in patients with ischemic stroke was 45.18% (89/197), and the median and quartile in the first part of MDQ score was 6.00 (5.00,10.00) points. The subjects were divided into BD group (n = 89) and non-BD group (n = 108) based on the presence of BD in patients with ischemic stroke. Education background (OR = 0.485), lesions involving the frontal or temporal lobes (OR = 2.724), sleep disorders (OR = 2.246), and daily living ability (OR = 3.108) were influencing factors for BD after ischemic stroke (P < .05).

Conclusion

The risk of BD after ischemic stroke is high. Based on the above research results, clinical attention should be paid to knowledge popularization, lesion examination, and the improvement of sleep quality and daily living ability, to prevent the occurrence of BD and improve the prognosis.

Yijinjing Qigong intervention shows strong evidence on clinical effectiveness and electroencephalography signal features for early poststroke depression: A randomized, controlled trial

Objective

Although Traditional Chinese Yijinjing Qigong Exercise (YJJQE) as mind-body intervention is popularly used among adults to ameliorate depressive symptoms in China, no randomized controlled trials (RCTs) are available to evaluate the effects of YJJQE in patients with poststroke depression (PSD). This study aims to explore the clinical efficacy and the neurological and psychiatric mechanism in brain network functional connectivity underlying electroencephalography (EEG).

Materials and methods

A total of 60 patients, diagnosed with mild PSD, were randomly (1:1) assigned to YJJQE group (n = 30) and control group of routine segmental rehabilitation training group (n = 30) for a 60-min exercise session once a day for 3 weeks. All outcome measures were collected at baseline and 3-weeks ending intervention. The primary outcome was the 24-item Hamilton Depression Scale (HAMD-24) score, evaluation at more time points for 1 month of follow-up. The secondary outcomes were EEG data in four frequency domains (δ, θ, α, and β), global efficiency (GE), local efficiency (LE), GE/LE curve [areas under the curve (AUC)], Phase Lag Index (PLI), (HAMD-24) Score and EEG correlation analysis.

Results

All patients showed no significant differences in baseline data. After 3 weeks and 1 month of follow-up, the YJJQE group demonstrated significant decreasing changes compared to the control group on the HAMD-24 scores (p < 0.001). Furthermore, the YJJQE group also showed a significant reduction in θ wave, and an increase in both GE and LE. Compared to the control group, the YJJQE Qigong group showed significantly greater functional connectivity in the δ, θ, and β frequency bands in the brain network of the degree of phase synchronization (p < 0.001). HAMD-24 Score and EEG correlation analysis negative correlation in the Qigong group θ wave (p < 0.001).

Conclusion

Our findings demonstrated that YJJQE is estimated to effectively alleviate the depressed mood of patients with PSD by promoting the efficiency in information transmission of network functional connectivity and its integration ability in different brain regions. Therefore, the YJJQE would be useful as a non-pharmacological treatment to prevent PSD.
