Study Description

Brief summary:

The main goal of this research proposal is to provide, for the first time in humans, a wider understanding of the role of the noradrenergic system both in health and illness (Parkinson's disease) through the use of a newly developed radiotracer (11Carbon [11C]Yohimbine) visualizing alpha-2 (α2) adrenergic receptors (AR) combined with cutting-edge technology, the hybrid positron emission tomography (PET)/magnetic resonance imaging (MRI) scanner. The secondary aim of this study will be to determine whether the expected age- and Parkinson's disease (PD)-related changes in the noradrenergic system are paralleled by changes in neuropsychological performances (such as cognitive, motor and/or olfactory abilities).

Arms and interventions
Arm Intervention/treatment
Experimental: Healthy controls
Other: The role of the noradrenergic system across the life span (Healthy Subjects)
A sample (n=90) of balanced distribution of healthy males and females within a continuous segment of the adult life span from 20 to 80 years old will be recruited, with approximately 7 males and 7 females subjects for each decade of age. Each participant will undergo 1) a neuropsychological examination, 2) an olfactory screening and 3) a 90 min 11C-Yohimbine positron emission tomography (PET)/magnetic resonance imaging (MRI) scan in a resting state.
Experimental: Parkinson disease
Other: The role of the noradrenergic system across the life span (Parkinson's Disease Subjects)
Three groups of Parkinson Disease (PD) patients (each of them n=15) will be studied according to the duration and stage of the disease: early stage (the same group in Task 2); mid stage (5-7 years of disease duration; Hoehn and Yahr in Off 2-3); late stage (7-10 years of disease duration; Hoehn and Yahr in Off 3-4).
Outcome Measures
  • Primary Outcome Measures: 1. Positron Emission Tomography (PET) and Magnetic Resonance Imaging (MRI) measures [ Time Frame: Day 1 -180 minutes ]
    Derived from the Positron Emission Tomography (PET) data, the binding potentials will be calculated using compartmental modelling techniques. Derived from the Magnetic Resonance Imaging (MRI) data.
  • Secondary Outcome Measures: 1. Global Cognitive Assessment [ Time Frame: Day 2 - 10 minutes ]
    Measured with Montreal Cognitive Assessment. Outcome measure is between 0 and 30. A score of 26 or over is considered to be normal.
  • 2. Memory Assessment [ Time Frame: Day 2 - 20 minutes ]
    Measured with the 16-item Free and Cued Recall test. Outcome measure is the total immediate recall which is the sum of free and cued recall.
  • 3. Working Memory Assessment [ Time Frame: Day 2 - 20 minutes ]
    Measured with the Digit Span Memory test. Outcome measure is the total number of items correctly repeated.
  • 4. Executive Functioning [ Time Frame: Day 2 - 20 minutes ]
    Measured with the Trail Making test. Unit of measure is first seconds to perform the test, which will be converted in a percentile score and then number of errors made during the test.
  • 5. Planning Functioning [ Time Frame: Day 2 - 20 minutes ]
    Measured with the Tower of London test. Outcome measure is the total correct and total moves score.
  • 6. Visuo-spatial Assessment [ Time Frame: Day 2 - 20 minutes ]
    Measured by the Visual Object and Space Perception Battery. The study will use a selection of theses tests : incomplete letters (outcome measure is between 0 and 20; cut-off score = 16) and position discrimination (outcome measure is between 0 and 10; cut-off score = 7)
  • 7. Depression Evaluation [ Time Frame: Day 2 - 10 minutes ]
    Measured by the Beck Depression Inventory-II Questionnaire. Outcome measure is between 0 and 20 with a cut-off score = 13. A score higher than 14 indicates the presence of depression.
  • 8. Anxiety Evaluation [ Time Frame: Day 2 - 10 minutes ]
    Measured by the State-Trait Anxiety Inventory (STAI) form Y questionnaire. Outcome measure is between 20 and 80, with higher scores correlating with greater anxiety.
  • 9. Praxic Abilities [ Time Frame: Day 2 - 10 minutes ]
    Measured by the Mahieux Praxic test. Outcome measure is between 0 and 23.
  • 10. Day time sleepiness evaluation [ Time Frame: Day 2 - 5 minutes ]
    Measured by the Epworth Sleepiness Scale Questionnaire. Outcome measure is between 0 and 24 with a score between 0-8 indicating normal Daytime sleepiness, a score between 9-14 indicating mild sleep deficiency and a score above 15 an excessive daytime sleepiness.
  • 11. Sleep Quality [ Time Frame: Day 2 - 5 minutes ]
    Measured by the Pittsburgh Sleep Quality Index (PSQI). Outcome measure is between 0 and 21 with 0 indicating no sleep problem and 21 major sleep disorder.
  • 12. Olfactory assessment : odor detection [ Time Frame: Day 2 - 30 minutes ]
    The odor detection capability will be evaluated using a phenyl-ethyl alcohol (PEA) test. In this experiment, the detection threshold is obtained using a "staircase" procedure. Outcome measure is between 0 and 16 with higher score indicating better performance.
  • 13. Olfactory assessment: odor discrimination [ Time Frame: Day 2 - 30 minutes ]
    Odor discrimination capacity will be assessed by asking the participant to smell three bottles (two bottles contain the same odor, and the third contains a different smell). The test includes 16 triplets of odorous substances. Outcome measure is between 0 and 16 with higher score indicating better performance.
  • 14. Olfactory assessment : odor identification [ Time Frame: Day 2 - 30 minutes ]
    The odor identification capacity will be estimated by the European test of olfactory capacities (ETOC), a test based on 16 identifications. Outcome measure is between 0 and 16 with higher score indicating better performance.
