• How short high-oxygen exposures affect brain blood flow during mechanical ventilation

  We will test whether brief, controlled increases in ventilator oxygen change brain blood flow in adults who are intubated and on mechanical ventilation in the ICU.

  Recruiting Erasme University Hospital · Brussels · NCT07377162

• How younger adults' brain blood vessels respond to changes in blood flow

  We will use MRI to test how brain blood flow changes during a simulated postural shift and while breathing more carbon dioxide in healthy adults aged 20–40, and whether prazosin changes those responses.

  Recruiting Phase 2 University of Wisconsin, Madison · Madison, Wisconsin · NCT06629090

• How brain blood vessels respond to changes in blood flow

  This project will test how brain blood flow changes during a simulated postural change and when breathing higher levels of carbon dioxide in adults aged 55–69.

  Recruiting Phase 2 University of Wisconsin, Madison · Madison, Wisconsin · NCT06629077

• Evaluating brain blood flow using contrast-enhanced ultrasound

  This study is testing a new ultrasound method to see if it can help doctors check blood flow in the brains of patients with recent brain injuries.

  Recruiting Assistance Publique - Hôpitaux de Paris · Paris · NCT05893407

• Moderate CO2 increase during anesthesia to boost collateral flow in clot removal for acute anterior stroke

  This study will test whether slightly higher blood carbon dioxide during anesthesia improves collateral blood flow and protects the brain in people having mechanical thrombectomy for anterior large-vessel ischemic stroke.

  Recruiting Phase 2 University Hospital, Clermont-Ferrand · Clermont-Ferrand · NCT05051397

• Understanding how heart rate affects blood flow in the brain

  This study is testing how changes in heart rate affect blood flow to the brain in patients with postural tachycardia syndrome to help improve their symptoms and quality of life.

  Recruiting University of Calgary · Calgary, Alberta · NCT04391465

Quick answers

How many Cerebrovascular Circulation clinical trials are recruiting right now?

6, as of November 12, 2026. We update this list each time we refresh our data from ClinicalTrials.gov.

Where are these trials running?

In 4 countries. The most sites are in United States (2 trials), France (2 trials), Canada (1 trial), Belgium (1 trial). Each study page lists its sites and which ones are recruiting.

What phases are they in?

Phase 2: 3. Trials with no phase listed are usually device, behavioural or observational studies.

How do I join one?

Open a study, check the "Is this trial a fit for you?" section, then contact the study team listed on the page. They will ask a few screening questions. Asking is free and does not commit you to anything. Talk it over with your doctor first.
