Brief summary
The purpose of this study is to confirm the improvement of movement during RBD in Parkinson's disease and to explore the neuronal network involved in this improvement using NIRS.
Detailed description
The aim of this study is to compare the quality of movement during REM sleep during RBD episodes and movement awake without and with dopaminergic treatment while measuring cortical activity using NIRS.
Interventions
OTHERNear Infrared Spectroscopy
Use of the near-infrared-spectroscopy (NIRS) to explore the cortical mechanism by which this sleep disorder would allow a disappearance of parkinsonian signs at night

Inclusion criteria
* Idiopathic Parkinson's Disease (Hughes AJ et al., 2001) * Patients with REM sleep behaviour sleep disorder according to the ICSD2 (International Classification of Sleep Disorders 2) criteria and frequent reported several times per week by the spouse * Informed written consent signed * Patient aged 40 to 90 years * Affiliate or benefiting from a social security scheme.
Exclusion criteria
* Atypical Parkinson's Syndromes * Patient not accepting polysomnography * Contraindications to cerebral Magnetic Resonnance Imaging (MRI): pacemaker, cochlear implants, certain heart valves, claustrophobia, pregnancy. * Limit of validity of the MRI: if the patient presents dyskinesias preventing immobile maintenance of a few minutes in the MRI for the acquisition of images
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Difference of signal NIRS on the supplementary motor area (SMA) during the movement realized during the REM sleep behaviour disorder (RBD) and reproduced in standby in the patient parkinsonian in on. | 24 hours | Difference of signal NIRS on the supplementary motor area (SMA) during the movement realized during the REM sleep behaviour disorder (RBD) and reproduced in standby in the patient parkinsonian in on (means that the patient is under effective dopaminergic treatment). The NIRS signal corresponds to the area under curve (AUC) of the oxyhemoglobin (O2Hb) and desoxyhemoglobin concentration's variation during duration of the movement. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Difference of NIRS signal in different cortical regions and in different conditions: rest, movement on and off, RBD, and in standby. | 24 hours | Difference of NIRS signal in different cortical regions and in different conditions: rest, movement on(means that the patient is under effective dopaminergic treatment ) and movement off (means that the patient has been weaned from any treatment for several hours), RBD (REM sleep behavior disorder), and in standby. |
| Difference of movement speed measured by accelerometers under different conditions. | 24 hours | — |
