Pilot study on the validity of the pupillographic sleepiness test in children and adolescents
2013
Abstract Objective To report preliminary validation data for the pupillographic sleepiness test (PST) in children and adolescents. Methods Twelve patients (13.1±4.4years of age) underwent the multiple sleep latency test (MLST) and three PSTs at 09:00, 11:00, and 13:00 on one single day. Correlations were tested between mean sleep latency and gender-adjusted z -values of the natural logarithm of the pupillary unrest index (zlnPUI). Results Spearman's correlation ( P -value) between the zlnPUI values obtained at 09:00 and 11:00 with the MSL was r S =−0.641 (0.025) and r =−0.553 (0.062). Conclusion There was satisfactory agreement between PST and the MLST, which is similar to what is found in …
Electrophysiological brain stem investigations in idiopathic narcolepsy.
1998
Narcolepsy is associated with various rapid eye movement (REM) sleep abnormalities. Distinct brain stem areas seem to play a prominent role in REM sleep regulation. Recent magnetic resonance imaging (MRI) studies have led to conflicting findings concerning the presence of structural brain stem lesions in patients with idiopathic narcoleptic syndrome. However, multimodal electrophysiological brain stem investigations may reveal functional brain stem abnormalities even in the absence of MRI abnormality. Therefore we investigated brain stem function in 12 idiopathic narcoleptic patients by systematically studying tegmental brain stem pathways. All of the patients met the diagnostic criteria of…
Validity of the Pupillographic Sleepiness Test for the diagnosis of daytime sleepiness in children and adolescents and its relationship to sleepiness…
2021
Objectives: To report validation data for the Pupillographic Sleepiness Test (PST) in children and adolescents, evaluate its applicability for diagnosing excessive daytime sleepiness and its relationship to sleepiness-associated outcomes. Methods: A cross-sectional diagnostic test accuracy study was performed. Patients underwent three PST at 9 a.m. (T1), 11 a.m. (T2) and 1 p.m. (T3) plus the Multiple Sleep Latency Test (MSLT) on a single day. Additionally, two neurocognitive tests were performed and three questionnaires about quality of life, sleep-related self-efficacy and behavioural aspects completed. Gender-stratified z-values of the natural logarithm of the Pupillary Unrest Index (z-ln…
