Scientists hunt for biomarkers to predict brain vessel disease
NCT ID NCT06960538
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This completed study looked at 200 people with cerebral amyloid angiopathy (CAA), a condition where protein builds up in brain blood vessels, raising the risk of bleeding and cognitive decline. Researchers collected clinical data, brain scans, and samples of spinal fluid and blood to find markers that could help predict how the disease will progress. The goal is to improve early diagnosis and personalize treatment, but this is an observational study, not a test of a new drug.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this study could point toward better ways to diagnose and predict the progression of cerebral amyloid angiopathy, potentially leading to personalized treatment targets.
- What could go wrong
- This is an observational study, not a treatment trial, so it will not directly provide a new therapy. The findings may not lead to immediate clinical changes.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * patients of either sex over 18 years of age; * patients with possible and probable symptomatic or asymptomatic CAA with or without histological demonstration (modified Boston criteria); * patients who have had at least one brain MRI. Exclusion Criteria: * patients who have contraindications to undergoing brain MRI (e.g., pacemaker, incompatible mechanical valves, claustrophobia); * patients who have contraindications to or refuse to undergo lumbar puncture; * patients who are unable to provide informed consent for the study due to aphasic or cognitive impairment; * patients who are pregnant or breastfeeding.
