Official title

A Pilot Cross-sectional Cohort Study of Right-to-left-shunt, Cerebrovascular Reactivity, Ischemic Infarct Burden on High Resolution MRI, and Cognitive Impairment in Elderly Subjects

Brief summary

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

The purpose of this study is to use transcanial doppler (TCD) ultrasound to look for possible risk factors for ischemic brain injury. We will perform contrast TCD with agitated saline contrast to identify and contrast right-to-left shunt (RLS) and breath holding to assess cerebrovascular reactivity (CVR) in the elderly.
