Pure Autonomic Failure (PAF)
A degenerative disease of the peripheral nervous system characterized by a marked fall in blood pressure upon standing (orthostatic hypotension). The orthostatic hypotension leads to symptoms associated with cerebral hypoperfusion, such as dizziness, fainting, visual disturbances and neck pain (Mathias, Mallipeddi & Bleasdale-Barr, 1999). Other symptoms such as chest pain, fatigue and sexual dysfunction may also occur. Symptoms are worse when standing and are sometimes relieved by sitting or lying flat.
