Official title: Cognitive Decline and Underlying Mechanisms in Symptomatic Intracranial Atherosclerotic Stenosis Patients: A Multicenter Cohort Study
Run by Anhui Medical University · NCT06336174 · Data updated 2026-11-12
This study looks at how narrowed brain arteries affect thinking and memory in people with symptoms to see what might be causing their cognitive decline.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are individuals with symptomatic intracranial artery stenosis who have a history of vascular-related transient ischemic attacks or acute cerebral infarctions.
✕Probably not a fit
Patients with a history of severe psychiatric illnesses, significant brain defects, or those who have had strokes or seizures may not benefit from this study.

What this trial studies
This observational study investigates the mechanisms behind cognitive impairment in patients suffering from symptomatic intracranial atherosclerotic stenosis (ICAS). Participants undergo a comprehensive medical evaluation, including neuropsychological testing, blood sample collection, and MRI scans at baseline, 3 months, and 1 year. The study aims to assess global cognitive function and specific cognitive domains while also monitoring emotional health and cerebrovascular events. Approximately 100 participants will be involved, providing valuable insights into the relationship between ICAS and cognitive decline.
Why it matters
Potential benefit: If successful, this study could lead to improved understanding and management of cognitive impairment in patients with symptomatic ICAS.
How similar studies have gone: While there have been studies on cognitive impairment related to cerebrovascular conditions, this specific approach focusing on symptomatic ICAS is relatively novel.
