There may be a loss of neurovascular coupling and reduced functional hyperemia in response to cognitive challenge under orthostatic stress – perhaps related to a loss of autoregulatory buffering of beat-by-beat fluctuations in arterial blood flow. [47] Causes [ edit ] A potential cause for brain fog is a decrease in cerebral blood flow (CBF), especially in upright position.

Associated with related symptoms that are worse with upright posture and that improve with recumbence. Pyridostigmine has been reported to restrain heart rate and improve chronic symptoms in approximately half of people. However, it may cause GI side effects that limit its use in around 20% of its patient population. [91] [21] Pederson CL, Blettner Brook J (2017-04-12).

There is an increasing number of studies indicating that POTS is an autoimmune disease. [51] [5] [56] [3] [57] [58] A high number of patients has elevated levels of autoantibodies against the adrenergic alpha 1 receptor and against the muscarinic acetylcholine M4 receptor.
