“…The case reports and case series had a mean score of 4.4 (maximum 6, median 5), ranging 3–6. Three studies were deemed of fair quality ( 15 , 16 , 18 ) and 5 of good quality ( 9 , 11 , 12 , 17 , 20 ). The modified NOS scores had a mean score of 6.6 (maximum 9, median 7), ranging 5–8.…”

“…Among the 1,869 unique studies identified by the search strategy, 43 studies were retrieved for full-text review (Figure 1). Of these, 13 met the inclusion criteria and were included in this review (Table 1) (6,(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20). The studies by Busweiler et al (10) and Jardine et al (6) reported on patients from the same cohort; however, the study by Busweiler et al (10) reported unique data on the body position and upper gastrointestinal symptoms which was not available in the larger, more recent cohort presented in Jardine et al (6).…”

BackgroundSleep syncope is a subtype of vasovagal syncope in which patients experience syncope after awakening from their sleep. The aim was to investigate the association of clinical characteristics and gastrointestinal symptoms with syncope, as well as the body position in which symptoms began.MethodsA systematic search of studies was performed in MEDLINE and EMBASE without language restrictions, from inception to 9 January 2022. Studies were included if they reported data on the proportion of patients who experienced symptoms (nausea, vomiting, abdominal pain, and diarrhea) associated with syncope.ResultsData were included for 116 patients in 13 studies. Patients were 46.9 ± 4.3 years and 61.4% were female. In 52.5% of patients, a supine body position at the time of syncope was reported. A history of phobias was reported by 67.6% of patients, and 96.5% of patients also had typical daytime vasovagal syncope. In the 5 studies reporting the results of head-up tilt testing (n = 77), 90.9% of patients had positive tests. Gastrointestinal symptoms were present in the majority of patients with reported rates of 65.6% for upper gastrointestinal symptoms and 86.0% for lower gastrointestinal symptoms.ConclusionPatients with sleep syncope patients are predominantly female with a history of daytime vasovagal syncope. Gastrointestinal symptoms are present in the majority of patients and is therefore an important feature of sleep syncope.

Parasomnias are unpleasant or undesirable behavioral or experiential phenomena that occur during sleep. Once believed unitary phenomena related to psychiatric disorders, it is now clear that parasomnias result from several different phenomena and usually are not related to psychiatric conditions. Parasomnias are categorized as primary (disorders of the sleep states) and secondary (disorders of other organ systems that manifest themselves during sleep). Primary sleep parasomnias can be classified according to the sleep state of origin: rapid eye movement sleep, non-rapid eye movement sleep, and miscellaneous (those not respecting sleep state). Secondary sleep parasomnias are classified by the organ system involved.
