Study: NCT06516016

Intervention type: RADIATION
Intervention: PET
Description: \[18F\]DPA-714 will be injected intravenously as a 1 minute intravenous bolus injection and dynamic PET acquisition will last 90 min. The aim is the quantification of the neuroimmune reaction during neuroinflammation process.

Intervention type: OTHER
Intervention: MRI 3T
Description: Brain MRI will aim at providing imaging biomarkers which will allow evaluating brain structure, microstructure, iron load, myelin, neurodegeneration of the substantia nigra and locus coeruleus, functional connectivity, brain perfusion and the glymphatic system.

Intervention type: OTHER
Intervention: Oculomotricity assessment
Description: Recording eye movements in a controlled environment (requiring no specific room or area) in binocular vision at a frequency \> 500Hz, while retaining infrared video footage of eye movements for high-quality clinical monitoring.

Intervention type: OTHER
Intervention: Magnetoencephalography assessment
Description: Recording brain magnetic activity using the Elekta Neuromag® TRIUX Magnetoencephalograph ; The participant will be comfortably seated in an adjustable-height chair. The device is enclosed in a shielded room isolated from external electric and magnetic fields to measure the extremely weak magnetic activities produced by the brain.

Intervention type: OTHER
Intervention: Body posture and gait assessment
Description: The acquisition of kinematic gait parameters will be achieved ; markers are positioned on the different segments of members, recognized by a camera system positioned on the walls. Neurophysiologic muscular activity of the lower limbs will also be recorded.
