A 19-year-old woman suffered from severe excessive daytime sleepiness accompanied with long sleep episodes both in the daytime and nighttime and frequent episodes of cataplexy shortly after the removal of craniopharyngioma in the intrasellar space. Multiple sleep latency test showed a typical finding of narcolepsy, and cerebrospinal fluid orexin(More)
Patients with obstructive sleep apnea syndrome (OSAS) sometimes have atrioventricular (AV) block during sleep. However, significant resolution of such AV block with treatment for OSAS has been reported. On the other hand, during rapid eye movement (REM) sleep, conduction disturbances not associated with the apnea event can be observed, particularly in young(More)
EEG arousals are seen in EEG records as awakening response of human brain. Obstructive sleep apnea (OSA) is one of serious sleep disorders. Sevier OSA brings about EEG arousals and sleep of patients with OSAS is frequently interrupted. Number of respiratory-related arousals during the whole night PSG recordings is directly concerned with the quality of(More)
This study is to clarify the effects of stimulating conditions on caloric response evoked by cold air stimulation. The five parameters of caloric nystagmus (latency, maximum slow phase velocity [Max. spv], Max. spv arrival time, frequency and duration) were examined. The different stimulating air temperature(0 degree C, 5 degrees C, 10 degrees C, 15 degrees(More)
The aim of this study was to assess the acute effects of clonazepam and clonidine on rhythmic masticatory muscle activity in young adults with primary sleep bruxism, as well as accompanying effects on sleep architecture and cardiac activity. This study used a double-blind, crossover, placebo-controlled design. Polysomnography was performed on 19 subjects(More)
The aim of this study was to investigate the association between patterns of jaw motor activity during sleep and clinical signs and symptoms of sleep bruxism. A total of 35 university students and staff members participated in this study after providing informed consent. All participants were divided into either a sleep bruxism group (n = 21) or a control(More)
We describe a handmade eye movement monitor featuring a piezoelectric device for use during transsphenoidal surgery (TSS). The sensor consists of a piezoelectric device, condensers, resistors, and several inexpensive parts. Eyeball movements elicited by surgical manipulations during TSS for cavernous sinus tumor are detected by small disc-shaped sensors(More)
