Adding Chinese herbal medicines to conventional therapy could decrease subsequent stroke risk for atrial fibrillation patients.
From a nationwide database, 11,456 AF patients aged ≧ 20 years between 1998 and 2007 were identified. Afterwards, we enrolled 2670 CHMs users and randomly selected 2670 non-CHMs users using the propensity score method. The occurrence of stroke was recorded until the end of 2012.
Within the follow-up period, 671 CHMs users and 900 non-CHMs users developed stroke, with incidence rates of 33.02 and 45.46 per 1000 person-years, respectively. CHMs use was associated with a 30% lower stroke risk, especially for those receiving CHMs for over two years.

Our dose-response analysis indicated that moderate green tea consumption (500–1000 mL/d) was associated with a 21% to 24% lower risk of stroke.

Systematic Review Green Tea Stroke Stroke Risk
The meta-analysis aimed to clarify the inconsistent findings in epidemiologic studies regarding the link between green tea consumption and stroke risk. Five prospective cohort studies, involving 645,393 participants and 11,421 stroke cases, were analyzed. The summary relative risk (RR) revealed a substantial association, indicating a 26% reduction in stroke risk with the highest green tea consumption. The dose-response analysis indicated a nonlinear relationship, and compared with non-consumers, various levels of green tea intake showed progressively reduced RRs for stroke, emphasizing a potential protective effect.
The findings from the meta-analysis strongly suggest an inverse association between green tea consumption and stroke risk. Notably, the highest green tea consumption demonstrated a significant 26% risk reduction. The dose-response analysis further highlighted a nonlinear relationship, with moderate consumption levels (500–1000 mL/d) showing the most substantial risk reduction. These results provide support for recommending green tea consumption as a measure for the primary prevention of stroke.
Higher daily tea consumption, especially green tea, is linked to a lower risk of cerebral hemorrhage in adults.

Systematic Review Cerebral Haemorrhage Green Tea Stroke
This meta-analysis uncovered evidence of a connection between tea consumption and cerebral hemorrhage risk, exploring databases including Web of Science, PubMed, Embase, and Scopus until December 2021. The synthesis utilized relative risks or odds ratios from observational studies. The pool of data included ten studies involving over 721,827 participants.
The evaluation revealed that a higher rate of tea consumption, and more specifically green tea, was significantly related to a lower risk of cerebral hemorrhage. Interestingly, this connection could be observed even when adjusted for key lifestyle factors such as alcohol consumption, fruit and vegetable intake, and physical activity. It is worth noting that the intake of tea on a daily basis demonstrated a protective effect against the risk of cerebral hemorrhage.
The existing evidence, although with low level of confidence, suggests that walnut intake may have a beneficial effect on cognition-related outcomes, including cognitive function, mood, and stroke.

The existing evidence, although with low level of confidence, suggests that walnut intake may have a beneficial effect on cognition-related outcomes, including cognitive function, mood, and stroke. Limitations in study design and comparability render the available evidence insufficient to draw a firm conclusion regarding the effects of walnut on cognition in adults. High quality studies and standardized interventions and measurement tools are necessary to determine the role of walnut intake in cognitive health.
Stroke patients who received acupuncture had a lesser risk of insomnia across various demographic and medical variables.
2021 Frontiers in Aging Neuroscience Acupuncture Reduced the Risk for Insomnia in Stroke Patients: A Propensity-Score Matched Cohort Study Qiu X, Han NS, Yao JX, Yu FR, Lin YY, Zhuang X
Cohort Study Acupuncture Insomnia Stroke
The study data was derived from the case database of a Chinese hospital, featuring stroke patients diagnosed between 2010 and 2019. These patients were sorted into two groups: one which received acupuncture and one which did not. The sorting was performed using a propensity score matching technique. Comparisons were made between the two groups using the incidence of insomnia as the primary indicator, with Cox regression analysis and the Kaplan-Meier method serving as the main analytical tools.
The results indicated that stroke patients who underwent acupuncture treatments were less susceptible to insomnia as compared to counterparts who didn't receive acupuncture treatment. This decrease in the incidence of insomnia was observed across various categories such as genders, age groups, stroke types and stroke locations, with the acupuncture group displaying a significantly lesser cumulative incidence of insomnia.
Higher coffee consumption, specifically 3-4 cups daily, is associated with a 21% lower risk of stroke, with no further reductions with increased intake.

Systematic Review Coffee Stroke Stroke Risk
The research utilized a systematic review and meta-analysis approach to investigate the link between coffee consumption and stroke risk. Random-effects models were employed to compile relative risk estimates. The assessment was structured to compare the highest and lowest categories of coffee consumption and utilized a one-stage robust error meta-regression model for stroke risk assessment. The study incorporated 21 separate studies which in total included over 2.4 million participants.
The findings suggest a significant inverse connection between coffee consumption and the risk of stroke. According to the pooled relative risk analysis, the highest versus the lowest categories of coffee consumption showed a decrease in stroke risk. There seems to be a nonlinear (U-shaped) relationship between stroke risk and coffee consumption, with the lowest risk (21% lower) associated with consuming 3-4 cups of coffee per day. Sensitivity analysis suggested the influence of each individual data set on the overall result wasn't significant, and while some evidence of publication bias was witnessed, additional analysis established that potential bias didn't impact the findings noticeably.
