This case presents a patient with extreme fatigue and excessive sleepiness. The tilt test provoked decline in cerebral blood flow velocity (CBFv) associated with decline in end tidal CO2, indicative of hypocapnic cerebral hypoperfusion (HYCH). There was also mild small fiber neuropathy affecting predominantly autonomic fibers associated with mild autonomic dysfunction.
