In Vivo Noradrenergic System and Aging
Diving Into the in Vivo Noradrenergic System : Role of the alpha2C-adrenergic Receptors
Source: ClinicalTrials.gov · Last updated 9 Jul 2026
Brief summary (registry, in English)
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 (here Parkinson's disease) through the use of a newly developed radiotracer visualizing alpha2C-ARs (\[11C\]ORM-13070) combined with a cutting-edge technology, the hybrid PET/MRI scanner. The secondary aim will be to determine whether the expected age- and PD-related changes in the noradrenergic system are paralleled by changes in neuropsychological performances (i.e. cognitive, motor and/or olfactory abilities).

Who cannot take part
Copied verbatim from ClinicalTrials.gov and grouped by topic. Only the trial team decides who can take part.
Prior treatment

- Subjects already participating in another biomedical research project or who have participated in a study using ionizing radiation within the past year;
- MRI contraindications (: people using pacemaker or insulin pumps, with implanted or embedded metal objects in the head or body, claustrophobic, with neurosensory stimulators or implantable defibrillators, with cochlear implants, with ferromagnetic foreign bodies in the eye or brain close to nerve structures, agitation of the subject (uncooperative or agitated subjects), ventriculoperitoneal neurosurgical shunt valves, dental appliances)
- Persons receiving psychiatric care.
Lab values
- Subject with a contraindication to PET scans at the ORM: hypersensitivity to the active substance or to any of the excipients (sodium chloride)
