Cerebral Blood Flow

Cerebral blood flow is a measure of how much blood reaches the brain in a specific period of time. For example, a typical value for cerebral blood flow is approximately 50 milliliters of blood per 100 grams of brain tissue per minute (mL/100g/min). 

In ME/CFS, issues with cerebral blood flow often present as orthostatic intolerance, when a person feels dizzy or faint after standing upright. In these cases, orthostatic intolerance may be a result of low blood flow to the brain.

OMF’s Melbourne ME/CFS Collaboration is conducting a study on cerebral blood flow in people with ME/CFS and how it might influence symptom severity and post-exertional malaise. Read more about the study here.
