Vascular cognitive impairment (VCI) refers to cognitive impairment primarily mainly caused by cerebrovascular pathologies and their risk factors. It is the second leading cause of cognitive impairment in individuals aged 60 and above in China. Currently, there are no specific treatments for VCI, but early identification and prevention can help reduce the risk of onset and improve patients\' prognosis. To raise awareness and attention among clinicians towards VCI and provide guidance for its standardized management, the Chinese Stroke Association Vascular Cognitive Impairment Subcommittee updated and revised the clinical classification, diagnostic procedures, neuropsychological evaluation criteria and imaging evaluation criteria and etc.on the basis of the Guidelines for the Diagnosis and Treatment of Vascular Cognitive Impairment in China (2019). Through systematic literature reviews, including meta-analysis, systematic review, randomized controlled trials, retrospective studies, clinical case-control studies, etc, evidence and recommendation levels were formulated according to the evaluation and evaluation criteria of recommendation classification, and a total of 8 recommendations were formed on the etiology, clinical classification, clinical manifestations, diagnostic criteria, prevention and treatment of VCI. A standardized diagnostic process for VCI suitable for the clinical practice in China was proposed, aiming at providing guidance for the standardized diagnosis and accurate treatment of VCI.

There is a paradigm shift in our understanding of white matter hyperintensities (WMH) found on brain imaging. They were once thought to be a normal phenomenon of ageing and, therefore, warranted no further investigation. However, evidence now suggests these lesions are markers of poor brain and cardiovascular health, portending an increased risk of stroke, cognitive decline, depression and death. Nevertheless, no specific guidelines exist for the management of incidentally found WMH for general medical practitioners and other clinicians ordering brain magnetic resonance imaging scans for diverse clinical indications. Informed by a literature review and expert opinion gleaned from stroke neurologists, medical and imaging specialists, and general practitioners, we present our consensus statement to guide the management of incidentally found WMH in adults.
When incidental WMH are found on brain imaging: Perform a detailed history and examination to screen for neurological events. Investigate for potential undiagnosed or undertreated cardiovascular risk factors, especially hypertension and diabetes mellitus. Commence intensive and individualised cardiovascular risk management when risk factors are uncovered. Treat underlying risk factors via accepted guidelines but note that antiplatelet and anticoagulant medications should not be prescribed for incidental WMH in the absence of an alternative indication.
A brain health opportunity. We consider the discovery of incidental WMH on brain imaging to represent an opportunity to investigate for common cardiovascular risk factors and to optimise brain health. This can be commenced and monitored by the general practitioner or physician without delay in waiting for an outpatient neurology review.

Ischemic stroke caused by acute large vessel occlusion is associated with high rates of disability and mortality. Endovascular interventional therapy is evidently an effective treatment for occlusion of large cerebral vessels within the relevant time window, but there is no established methodological standard for recanalization interventional therapy. The Professional Committee of Interventional Neurology in Chinese Research Hospital Association organized cerebrovascular disease experts in China and developed the expert consensus described herein, to provide a reference for clinicians to formulate technical strategies for recanalization of acute cerebral vascular occlusion.

Intracranial aneurysm is a common disease in neurosurgery, and intraoperative vascular injury causes postoperative ischemic complications that seriously influence patient prognosis. Intraoperative neurophysiological monitoring (IONM) enables effective identification of early intraoperative ischemia and thus reduces related complications. The Clinical Neurophysiology Committee of the Chinese Research Hospital Association and the Neurosurgeons Branch of the Chinese Medical Doctor Association organized national experts in neurophysiology and cerebrovascular disease to develop this expert consensus based on a review of published guidelines, consensuses and clinical evidence both at home and abroad, and after Delphi expert consultation. A consensus was formed on four aspects, including commonly used IONM techniques and parameter settings, perioperative preparation and interpretation of results, the value of intraoperative electrophysiological monitoring of aneurysms at different sites, and electrophysiological monitoring in special cases. Moreover, according to level of evidence recommended by GRADE criteria, nine recommendations were put forward from the above four aspects to provide a reference for clinical intracranial aneurysm intraoperative neurophysiological monitoring practice.

Ginkgo biloba Extract( GBE50) Dispersible Tablets is a new standardized prescription,which is widely used in the treatment of ischemic cardiovascular and cerebrovascular diseases. However,there are still many problems in its clinical application.Rational and safe use of GBE50 Dispersible Tablets is pivotal to the medication safety and clinical prognosis of patients. This consensus has been jointly formulated by clinical experts of traditional Chinese medicine and western medicine in cardiovascular and cerebrovascular diseases and followed the Manual for the Clinical Experts Consensus of Chinese Patent Medicine published by the China Association of Chinese Medicine. The present study identified clinical problems based on clinical investigation,searched the research papers according to PICO clinical problems,carried out evidence evaluation,classification,and recommendation by GRADE system,and reached the expert consensus with nominal group technique. The consensus combines evidence with expert experience. Sufficient evidence of clinical problems corresponds to " recommendations",while insufficient evidence to " suggestions". Safety issues of GBE50 Dispersible Tablets,such as indications,usage and dosage,and medication for special populations,are defined to improve clinical efficacy,promote rational medication,and reduce drug risks. This consensus needs to be revised based on emerging clinical issues and evidencebased updates in practical applications in the future.

Individuals undergoing rehabilitation often experience nutritional problems such as malnutrition, but there are no clinical practice guidelines (CPGs) specifically tailored to the combination of rehabilitation and nutritional care for these patients. The Japanese Association for Rehabilitation Nutrition aimed to develop CPGs for rehabilitation nutrition to support clinical decision making in daily practice.
A CPG committee and development process based on the Grading of Recommendations Assessment, Development and Evaluation system and the Minds Handbook for Clinical Practice Guideline Development 2014 was established. Four clinical questions were defined for patients undergoing rehabilitation for cerebrovascular disease, hip fracture, cancer, and acute illness. Literatures of randomised control trials (RCTs) up to April 2020 were searched for using the MEDLINE, EMBASE, CENTRAL, and Ichushi-web databases. After screening, full-text papers were assessed for eligibility for analysis. Subsequently, studies included in the systematic review were examined regarding their risk of bias, and underwent meta-analyses. A CPG development committee drafted the guidelines based on the systematic review report. Final recommendations were determined by the panel members.
Four recommendations were made based on 4 to 9 RCTs for each disease/condition. The certainty of the evidence ranged from very low to low. Overall, the enhanced nutritional care was weakly recommended for rehabilitation patients with cerebrovascular disease, hip fracture, cancer, and acute illnesses.
This CPG provides tentative recommendations for nutritional care of individuals undergoing rehabilitation. Due to low certainty of evidence and small sample sizes of the included studies, more high-quality and larger RCTs are needed to develop more practical CPGs.

Cerebrovascular disease is the leading cause of death and disability in China, causing a huge burden among patients and their families. Hence, stroke prevention is critical, especially in the high-risk population. Here, we present the evidence-based guideline suitable for the Chinese population.
Literature search of PubMed and Cochrane library (from January 1964 to June 2019) was done. After thorough discussion among the writing group members, recommendations were listed and summarised. This guideline was reviewed and discussed by the fellow writing committees of the Chinese Stroke Association\'s Stroke.
This evidence-based guideline was written in three parts: controlling the risk factors of stroke, utilisation of antiplatelet agents and assessing the risks of first-ever stroke. All recommendations were listed along with the recommending classes and levels of evidence.
This guideline provides recommendations for primary prevention of cerebrovascular disease among high-risk population in China. Controlling related risk factors, appropriately using antiplatelet agents, assessing the risk of developing first-ever stroke should help reduce the rate of cerebrovascular disease in China.
