A condition of underestimation of sleep is classified as paradoxical insomnia or sleep state misperception. However, overestimation of sleep, so called positive sleep state misperception has not been clearly described.Here we report a middle-aged woman with positive sleep state misperception who presented excessive sleepiness mimicking hypersomnia.
Sleep-related laryngospasm is a rare cause of sleep-related breathing disturbance which produce stridor or interruption of airflow associated with a distinct polysomnography arousal pattern. We report a case of a sixty-five-year-old woman who was referred for awakenings with abrupt respiratory distress and fear of suffocation. A polysomnography showed a total or near-total cessation of airflow, followed by choking and stridor for several minutes with a rapid increase in heart rate. Temporary hoarseness was seen. The esophageal pH monitoring indicated acid reflux, which confirmed gastroesophageal reflux disease. The protonpump inhibitor eliminated the sleep-related laryngospasm.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
