The main questions it aims to answer are:\n\nCan specific biomarkers help in identifying high-risk individuals before disease onset? Can these biomarkers predict disease progression and treatment response? Researchers will compare patients diagnosed with ICVD and healthy controls from a medical check-up center to assess differences in biomarker expression and their clinical significance.\n\nParticipants will:\n\nProvide blood, cerebrospinal fluid, urine, and stool samples for biomarker analysis.\n\nUndergo clinical imaging (CT, MRI, PET-CT) and functional assessments. Be followed up at 3, 6, 12, 24, 36, and 48 months for clinical outcomes and biomarker changes.\n\nThis study aims to develop a comprehensive biomarker-based prediction model to enhance the diagnosis and management of ischemic cerebrovascular disease.', 'detailedDescription': 'The detaited information about this trial is described below\n\n1.
