    Review Cerebral Blood Flow in Orthostatic Intolerance, 2025, Muhammad Shahzeb Khan, MD, MSC et al

    Abstract Cerebral blood flow (CBF) is vital for delivering oxygen and nutrients to the brain. Many forms of orthostatic intolerance (OI) involve impaired regulation of CBF in the upright posture, which results in disabling symptoms that decrease quality of life. Because CBF is not easy to...

    Measuring cerebral hypoperfusion with Doppler ultrasound

    I've been trying to organise this test for my daughter for some time, so we've read as much on it as we can. Gets a bit technical sometimes. In the literature, I've noticed that some groups measure at the carotid (and sometimes also vertebral) artery, and some groups measure at the middle...
