Study population

The study will focus on subjects potentially at high risk of developing a degenerative disease, compared to a control population of healthy volunteers and relatives with no evidence of genetic mutation under study, radiologically isolated syndrome (RIS), Idiopathic rapid eye-movement (REM) sleep behavior disorder (iRBD) and abnormal elevated levels of protein ptau217.

Inclusion criteria

      • Isolated REM sleep behavioral disorder
      • Radiological isolated syndrome
      • Abnormal brain protein aggregates
    2. For controls only :

      • Absence of symptoms or diagnosis of neurodegenerative disease (or criteria corresponding to at risk group)

Exclusion criteria

    • Refusal of blood draw or brain MRI
    • MRI contraindication (see criteria section)
    • Known allergy to gadoteric acid

    • Person under legal protection (legal guardianship, tutelage or maintenance of justice)
    • Person without any protection and unable to consent
    • Other medical, neurological, psychiatric, or social conditions that in the investigator's opinion are likely to interfere with study conduct.

Groups and cohorts

  • 800 presymptomatic participants

    * Visit interview * Neurological evaluation (NeuroPrems Scale and Self-administered REDCap questionnaires) * Psychological evaluation (Motivation, life trajectories and experiencies and semi-structured interview) * Cognition and behavior evaluation (Neuropsychological battery and Self-administered REDCap QR) * Imaging (MRI 3T and PET DPA-714) * Neurophysiology (Eye movement recording, Magnetoencephalography, Body posture and gait recording, voice and language recording) * Skin aging (Skin quantitative elasticity assessment) * Sleep (Videopolysomnography) * Biosampling (Blood draw, lumbar puncture, saliva sampling, skin biopsy, nasal brush and tear fluid collection)

    Radiation: PET · Other: MRI 3T · Other: Oculomotricity assessment · Other: Magnetoencephalography assessment · Other: Body posture and gait assessment · Other: Voice recording · Other: Video-polysomnography · Biological: Blood sampling, skin biopsy, excreta sampling, lumbar puncture

  • 200 healthy volunteers

    * Visit interview * Neurological evaluation (NeuroPrems Scale and Self-administered REDCap questionnaires) * Psychological evaluation (Motivation, life trajectories and experiencies and semi-structured interview) * Cognition and behavior evaluation (Neuropsychological battery and Self-administered REDCap QR) * Imaging (MRI 3T and PET DPA-714) * Neurophysiology (Eye movement recording, Magnetoencephalography, Body posture and gait recording, voice and language recording) * Skin aging (Skin quantitative elasticity assessment) * Sleep (Videopolysomnography) * Biosampling (Blood draw, lumbar puncture, saliva sampling, skin biopsy, nasal brush and tear fluid collection)

Interventions

  • RadiationPET

    \[18F\]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.

  • OtherMRI 3T

    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.

  • OtherOculomotricity assessment

    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.

  • OtherMagnetoencephalography assessment

    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.

  • OtherBody posture and gait assessment

    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.

  • OtherVoice recording

    Participants will be recorded during a single session at every visit upon baseline with a professional quality head mounted microphone.

  • OtherVideo-polysomnography

    Participants will complete standard sleep questionnaires before the visit and perform neurophysiological tests including cognitive tasks before and after the sleep recording.

  • BiologicalBlood sampling, skin biopsy, excreta sampling, lumbar puncture

    Experimental analyses, genetic and multi-OMIC analyses for biomarker research.

What researchers measure

Primary outcomes

  1. Rate of change of clinical, neurophysiological, anatomical and molecular marker profiles of neurodegenerescence and neuroinflammation in presymptomatic individuals

    Clinical markers will be: neurological and neuropsychological testing, and questionnaires; Neurophysiological markers will link functional brain networks and cognitive processes by using MEG, kinematic or eye movement recordings; Anatomical markers will be: cerebral MRI, glymphatic imaging, PET and skin elasticity; Molecular markers will be: blood, CSF, skin cells, iPSC derived biomarkers, transcriptomic, proteomic and metabolomic signatures

    Time frame: Baseline, Year 1, Year 2, Year 3, Year 4 and Year 5

Secondary outcomes

  1. Intra-individual change in trajectory profiles determined by multimodal analysis

    Determination by individual parameters form multimodal analysis

    Time frame: Baseline, Year 1, Year 2, Year 3, Year 4 and Year 5

  2. Rate and mean time to symptomatic conversion/progression

    Conversion/progression defined according to international criteria for the clinical diagnosis of each disease

    Time frame: Baseline, Year 1, Year 2, Year 3, Year 4 and Year 5

  3. Mean time of onset in genetically presymptomatic individuals

    Estimated time to onset in genetic presymptomatic individuals from the average age at diagnosis among affected family members

    Time frame: Baseline, Year 1, Year 2, Year 3, Year 4 and Year 5

  4. Rate of change for each study marker

    Period of changes defined (1) as breakpoints in the longitudinal evolution; (2) early, intermediate or late progression for each marker in the whole cohort and for each pathological group

    Time frame: Baseline, Year 1, Year 2, Year 3, Year 4 and Year 5

  5. Rate of change in the self-administered questionnaires

    Changes in the self-administered questionnaires on motivation, barriers and psychology

    Time frame: Baseline, Year 1, Year 2, Year 3, Year 4 and Year 5

  6. Rate of change in consumption of information issued from Consultations, hospitalizations and medication prescriptions

    Data from SNDS will be extracted during a 10-year period before and 10-year after the cohort entry. This follow-up should allow for a better understanding of when conversion occurs and to compare pathologies which involve a fairly broad spectrum of evolution.

    Time frame: From Year -10 to Year 10 (annual update)

  7. Time to loss of autonomy

    Rate of change from baseline of at least 0.1 in the utility index from EQ-5D-51

    Time frame: Baseline, Year 1, Year 2, Year 3, Year 4 and Year 5
