Recognizing Upper Airway Resistance Syndrome- Prominent cause for Excessive Daytime Sleepiness and Fatigue
Upper Airway Resistance Syndrome (UARS) was first named by Guilleminault while investigating excessive daytime sleepiness with no identified cause in adults. 1 It appears that UARS is a part of the continuum between primary snoring and obstructive sleep apnea syndrome. Some researchers believe that it is a distinct syndrome from Obstructive sleep apnea-hypopnea syndrome (OSAHS). American Academy of Sleep Medicine considers UARS as a part of OSAHS.
