Investigation of Clinical Feature and Brain Function in Narcoleptic Patients

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

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.

Inclusion Criteria:

• Narcolepsy meet to the international classification of sleep disorder,3rd edition (ICSD-3) , and RBD meet to the minimal diagnostic criteria according to the international Classification of Sleep, control subjects .

Exclusion Criteria:

History of heart disease History of central nervous system organic psychosis AHI>15次/h History of alcohol dependence and drug abuse
