Additionally, CVSS and CVST patients will undergo a 3-month follow-up to investigate the interrelationships and longitudinal changes among clinical parameters, glymphatic function, and white matter integrity.",[74],"Cerebral Venous Sinus Thrombosis",[76,77,78,79],"cerebral venous sinus thrombosis","cerebral venous sinus stenosis","glymphatic system","white matter integrity","NOT_YET_RECRUITING","2025-07-09",{"date":83,"type":84},"2025-07-18","ACTUAL",{"date":86,"type":70},"2025-07",{"date":88,"type":70},"2026-10",{"name":5,"class":6},1]
