Abstract
Dear Editor, Campbell et al. report an interesting association between nightmares and cardiovascular (CVS) risk [1]. The methodology in this work, however, is limited in ways that must be addressed in future research. In clinical sleep medicine as well as in several sleep research investigations, it is apparent chronic nightmare disorder often co-exists with sleep-disordered breathing (SDB) [2], either in the traditional and easily diagnosed form of obstructive sleep apnea (OSA) or in the atypical, somewhat disguised form of upper airway resistance syndrome (UARS) [3].
