Official title

The Natural History of Blood-Brain Barrier Disruption in Stroke Patients With White Matter Hyperintensities (A Cohort Study)

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Background: A stroke occurs when not enough blood reaches the brain. Sometimes stroke causes changes in certain brain matter. This is called white matter hyperintensity (WMH) and can lead to mental decline. But not all WMH is caused by stroke. Not all people with WMH experience mental decline. Researchers want to learn more about WMH. They want to see if it is related to disruptions in the blood-brain barrier. Objective: To better understand the how blood-brain barrier disruption is related to white matter hyperintensities. Eligibility: Adults at least 18 years old who have been admitted to a study site with stroke-like symptoms Design: Participants will be screened with an MRI scan and cognitive tests. Participants will have 11 visits over 6 years. Each visit will be 3-4 hours. At each visit, participants will: Update their medical history Have a thin plastic tube (catheter) inserted into an arm vein by needle Have an MRI. The scanner is a metal cylinder in a strong magnetic field. Participants will lie on a table that slides in and out of the cylinder. Participants will be in the scanner about 60 minutes, lying still for up to 20 minutes at a time. They will get earmuffs for loud sounds. Have a dye injected through the catheter during the MRI Have tests of movement, language, and cognition Some participants will have an extra visit for an MRI in a stronger scanner (7T MRI). Participation for some participants will be authorized by their legal representative.
