Orthostatic cerebral hypoperfusion syndrome[edit | edit source]
Novak (2016) states that orthostatic cerebral hypoperfusion syndrome (OCHOs) is defined by:
- abnormal orthostatic drop of cerebral blood flow velocity (CBFv) during the tilt test and
- absence of orthostatic hypotension, arrhythmia, vascular abnormalities, or other causes of abnormal orthostatic CBFv

cerebral blood flow (CBF) - the amount of blood that goes through the arterial tree in the brain in a given amount of time
chronic fatigue syndrome (CFS) - A fatigue-based illness. The term CFS was invented invented by the U.S. Centers for Disease Control as an replacement for myalgic encephalomyelitis (ME). Some view CFS as a neurological disease, others use the term for any unexplained long-term fatigue. Sometimes used as a the term as a synonym of myalgic encephalomyelitis, despite the different diagnostic criteria.
