It is also a common cause of stroke. Among people over 60 years old, the prevalence of CSVD exceeds 80%, and it is speculated that the number of CSVD patients in China exceeds 200 million, far higher than the number of stroke patients. CSVD can cause about 20% of stroke and 50% of dementia, while also doubling the risk of dementia and death, and tripling the risk of stroke. It is an important cause of death and disability in elderly people in China.\n\nStroke is a kind of cerebrovascular diseases characterized by sudden localized or diffuse neurological deficits caused by cerebral blood circulation disorders, and is the main clinical phenotype of cerebrovascular diseases. Stroke is characterized by high incidence rate, high disability rate, high mortality, high recurrence rate, and high economic burden. It is the first cause of death and disability in adult in China.\n\nMicrocirculatory disorders may play an important role in the pathophysiological process of ischemic CSVD. The pathological process of CSVD involves various components of the neurovascular units, including the blood-brain barrier composed of vascular endothelial cells, basement membrane, pericytes, and astrocytes, as well as oligodendrocytes, neurons, and extracellular matrix, etc.Among them, the disruption of the blood-brain barrier and endothelial damage are considered to be the initial stage of the pathological process of CSVD, causing the destruction of various secondary microcirculation structures and functions, namely the occurrence of microcirculatory disorders.\n\nMicrocirculatory disorders may also play a major role in the occurrence and development of ischemic cerebrovascular disease. By exploring multiple omics markers such as specific molecular biological markers related to ischemic cerebrovascular disease in the pathophysiological pathways of microcirculatory disorders, traditional risk factors and imaging markers can be combined to create prediction models for ineffective reperfusion of acute ischemic stroke and progression of CSVD, providing scientific evidence for improving the prognosis of acute ischemic stroke and CSVD.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'samplingMethod': 'PROBABILITY_SAMPLE', 'studyPopulation': 'Study 1: Patients with acute ischemic stroke.\n\nStudy 2: Patients with ischemic stroke during the recovery period.\n\nStudy 3: Patients with cerebral small vessel disease based on STRIVE classification.', 'eligibilityCriteria': "Inclusion Criteria:\n\nStudy 1:\n\n1.
