Neurovascular coupling (NVC) refers to the "regulation of cerebral blood flow to match brain activity, which is critically important for normal brain function".[1] Abnormal neurovascular coupling is a hypothesis being investigated to find out if it is underpinning cause of chronic fatigue syndrome. In 2019, Dr Zack Shan was awarded a grant to research neurovascular coupling in CFS.[1]
Theory[edit | edit source]
According to Stewart et al. (2012) the cerebral perfusion may be contributing to the brain fog (neurocognitive dysfunction) found in patients with CFS may POTS.[2][3]
