OBJECTIVE Sleep disorders in Parkinson's disease are very common. Polysomnography (PSG) is considered the gold standard for diagnosis. The aim of the present study is to assess the prevalence of nocturnal sleep disorders diagnosed by polysomnography and to determine the associated clinical factors. METHOD A total of 120 patients with Parkinson's disease were included. All patients underwent a...

OBJECTIVE This study was conducted to identify differences between people with narcolepsy and the normal control of delta and theta activity using electroencephalogram (EEG) spectrum analysis of nocturnal polysomnography (PSG). METHODS Seven narcolepsy patients and seven age-sex matched normal controls underwent PSG and multiple sleep latency tests. Participants' non-rapid eye movement (NREM)...

Transcutaneous capnography is a noninvasive method useful for analysis of the behavioral tendency of transcutaneous CO2 pressure (PtcCO2) in patients undergoing polysomnography, to evaluate respiratory sleep disorders. Objective: Determine normative PtcCO2 values in normal patients undergoing polysomnography. Method: One hundred seventy-nine patients who underwent polysomnography with simultane...

A 23-year-old woman without history of antecedent vocal, respiratory, or sleep disorders received vagus nerve stimulation (VNS) therapy for refractory partial epilepsy and developed sleep-related stridor during the course of parameter titration. Reduction of VNS current during polysomnography completely eliminated stridor. We conclude that VNS may cause sleep-related stridor in rare cases, expa...

OBJECTIVE To validate the accuracy of the Bedbugg, a new home monitoring device for diagnosis of obstructive sleep apnea. STUDY DESIGN AND SETTING Simultaneous sleep monitoring was performed by formal polysomnography and by Bedbugg. Monitoring was performed in a university sleep center in 42 subjects who had previously been scheduled for polysomnography. RESULTS The correlation for the apne...

BACKGROUND The most common cause of pediatric obstructive sleep apnea (OSA) is adenotonsillar hypertrophy. As such, palatine tonsillectomy with or without adenoidectomy is the first-line treatment for OSA, which can significantly improve the sleep and behavioral disturbances associated with OSA in the majority of patients. However, even after adenotonsillectomy, a reported 20% to 40% of patient...

BACKGROUND Manual analysis of sleep, breathing, and oxygenation records is the "gold standard" for diagnosing sleep abnormalities but is time consuming and cumbersome. The accuracy and cost of a computerised sleep analysis system have therefore been investigated. METHODS Manual and computerised (CNS Sleep Lab) scores from 43 consecutive clinical sleep studies were prospectively compared for a...
