Journal ArticleDOI
The REM sleep behavior disorder screening questionnaire—A new diagnostic instrument
Karin Stiasny-Kolster,Geert Mayer,Sylvia Schäfer,Jens Carsten Möller,Monika Heinzel-Gutenbrunner,Wolfgang H. Oertel +5 more
TL;DR: In this paper, the authors validated a 10-item patient self-rating questionnaire (maximum total score 13 points) covering the clinical features of idiopathic REM sleep behavior disorder (RBD) and found that the questionnaire poorly discriminated patients with the most challenging differential diagnoses such as sleepwalking or epilepsy.
Journal ArticleDOI

TL;DR: In a prospective multicentre study involving 1280 patients with idiopathic RBD, Postuma et al. test the predictive power of 21 prodromal markers of neurodegeneration, providing a template for planning neuroprotective trials.
Journal ArticleDOI
Combination of idiopathic REM sleep behaviour disorder and olfactory dysfunction as possible indicator for α-synucleinopathy demonstrated by dopamine transporter FP-CIT-SPECT
Karin Stiasny-Kolster,Y Doerr,Jens Carsten Möller,H Höffken,T M Behr,Wolfgang H. Oertel,Geert Mayer +6 more
TL;DR: It is shown that RBD patients have a profound impairment of olfactory function, which correlates with the neuropathological staging of Parkinson's disease (stages 1-3) as proposed by Braak.
Journal ArticleDOI
Narcolepsy is strongly associated with the T-cell receptor alpha locus.

TL;DR: The authors found association between narcolepsy and polymorphisms in the TRA@ (T-cell receptor alpha) locus, with highest significance at rs1154155 (average allelic odds ratio 1.69, genotypic odds ratios 1.94 and 2.55, P < 10(-21), 1,830 cases, 2,164 controls).

TL;DR: Current understanding of how genetic, environmental and immune-related factors contribute to a prominent orexin signalling deficiency in patients with NT1 are focused on, along with uncertainties concerning the ‘narcoleptic borderland’, including narcolepsy type 2 (NT2).
