Togo and colleagues 1 in a study to identify respiratory and movement sleep disorders in chronic fatigue syndrome CFS patients with and without fibromyalgia FM employed an apnea-hypopnea index AHI of 18 events per hour as the normal limit and reported an absence of diagnosable sleep-disordered breathing SDB . They utilized 18 events per hour as being a threshold sufficient to account for excessive daytime sleepiness and did not report the observed AHI. An institutional task force established five events per hour as the normal AHI limit based on an ample literature review. The Wisconsin Sleep Cohort Study provides evidence that an AHI ranging from 0.1 to 5 events per hour is enough to increase the risk of developing high blood pressure by 42 2 . From an AHI of 0.1 to one of 18 events per hour which cut-off point should be used in FM research Should it be derived from the emergence of symptoms from literature reviews or from hypertension research Our group has shown that 50 of women with any degree of SDB present with FM 3 . Adrenergic stimulus is a potential cause of FM through the model of sympathetically maintained neuropathic pain syndrome 4 5 and the central .
