About this study
Official title: Feature of Polysomnography and Cerebral Metabolism and Function in Narcolepsy With/Without RBD and Control Subject
This study evaluates the PSG and cerebral metabolism and functions in narcolepsy with/without RBD
Read the detailed description
Polysomnographic (PSG) work-up one night to record nocturnal sleep condition in narcolepsy with /without RBD and control subjects including sleep macrostructure, occurrence of sleep onset rapid eye movement period(SOREMP), sleep stages distribution, and sleep arousle and leg movement and apnea hyponea index would be calculated.
Functional magnetic resonance imaging (fMRI) has been used in human to nonivasiverlyn investigate the neural mechanisms. This technique also apply to measures the variations in brain perfusion, structure and morphology in narcolepsy patients by assessing the blood oxygen level-dependent (BOLD) signal diffusion tensor imaging (DTI and voxel-based morphometry(VBM)
This study compare the feature of PSG and fMRI between narcolepsy with RBD, narcolepsy without RBD, control subject to evaluates the PSG and cerebral metabolism and functions in narcolepsy with/without RBD.

How can a doctor refer a patient or contact the research team?
Contact Guoyan Chen, MD (86-02984717792, chenguoyan29@126.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
video-polysomnographic(PSG) (time frame: up to 100 weeks). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
