What this trial studies

This observational study aims to collect and analyze data from patients aged 40 and older who have significant narrowing (≥ 50%) in their intracranial or carotid arteries. Participants will undergo standard medical treatment and may receive interventional stenting, while their clinical information, neuropsychological assessments, and multimodal MRI results will be documented. The goal is to identify cognitive impairments associated with these conditions early on, enhancing understanding and management of cognitive function in affected patients.

Who should consider this trial

Good fit: Ideal candidates are patients aged 40 and older with at least 50% stenosis in a unilateral intracranial or carotid artery.

Not a fit: Patients with a history of major head trauma, intracranial surgery, or severe sensory impairments may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to earlier identification and better management of cognitive impairments in patients with intracranial or carotid stenosis.

How similar studies have performed: While similar studies have explored cognitive function in vascular conditions, this specific approach focusing on early identification in a defined patient population is relatively novel.
