Brief Summary
Up to 50% of Narcolepsy-cataplexy (NC) patients suffer from REM sleep behavior disorder (RBD), a parasomnia. A strong link was found between RBD and impulse control disorders (ICD) in Parkinson disease (PD) patients. ICD are thought to be related to a dysfunction of meso-cortico-limbic pathways which belong to the so called ''reward system''. A recent study in IRMf shows that RBD is associated with impaired reward system. A strong link was found between these two disorders and therefore we believe that RBD is associated with impaired reward system in NC The main objective of this study is to evaluate differences in brain activation between NC patients with and without RBD. The investigators hypothesize that NC patients with RBD have a more severe dysfunction of the reward system (hypoactivation of the meso-cortico-limbic pathway) than patients without RBD.

Interventions
Session will be of about 45 minutes. The reward system will be explore using an experimental task during functional Magnetic Resonance Imaging (fMRI). The name of this task is the"monetary incentive delay task".
Video polysomnography will be perform in the sleep center during one night if patient did not have vPSG for 1 year.
The investigators hypothesize that NC patients with RBD have a more severe dysfunction of the reward system (hypoactivation of the meso-cortico-limbic pathway) than patients without RBD.
Eligibility Criteria
You may qualify if:
- \- Men or women, right handed, 18 to 80 years
- Patients with type 1 Narcolepsy according to the criteria of the International Classification of Sleep, 3rd version, 2014
- Acceptance of the protocol and signature of a written consent
