E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary aim of the study is to assess regional brain synaptic density in MS patients of various duration and to determine whether a significant regional decrease in synaptic density can be detected, at the individual level, in comparison to age-matched healthy participants, using PET scanning and [18F]-UCB-H.
|
L'étude vise à déterminer si la densité synaptique régionale cérébrale du cerveau de patients atteints de sclérose en plaques, telle qu'estimée en tomographie à émission de positons par injection de [18F]-UCB-H, diffère de celle de participants sains.

E.3 | Principal inclusion criteria |
Participants, selected at the specialized MS outpatient clinic of the CHU of Liège, consist of patients with a diagnosis of RRMS according to Mc Donald criteria 2017, with no evidence of clinical progression. In order to eschew interference of recurrent relapses, patients have to be relapse-free for at least 6 months at the time of inclusion. Other inclusion criteria include: - Willingness to participate to the study - Good general health (except for MS) - Visual and auditory acuity adequate for testing - Completed at least six grades of education (i.e., exclude mental retardation)
In addition, healthy control participants, matched with patients for sex, age and socio-cultural level will be recruited through advertising in local newspapers, radios, communities, sport clubs and word of mouth. Inclusion criteria are the same as for patients, with the exception of MS.
|
Des patients souffrant de la forme rémittente de la sclérose en plaques, sans signe de rpogression, seront recrutés à la policlinique de neuroimmunologie du CHU de Liège, selon les critères diagnostiques de McDonald 2017. Les patients devront être libres de toute poussée depuis 6 mois au moins. Comme autres critères d 'inclusion, citons: - le consentement à participé à l'étude - une bonne santé générale, en dehors de la sclérose en plaques - une bonne vue et une audition normale - une éducation d'un niveau minimum d'école primaire. Des participants sains seront recrutés par voie d'affiche, appels radio, clubs de sport, etc selon les mêmes critères d'inclusion, excepté la sclérose en plaques.

E.4 | Principal exclusion criteria |
- Presence or history of neurological diseases other than MS, psychiatry diseases, major traumatic brain injury, major surgery , uncontrolled infection or medical condition, Female patient without contraception, physical or behavioural state incompatible with the current protocol (including MR compatibility, pregnancy, tutorship or guardianship.
|
- Antécédent ou présence d'une maladie du système nerveux autre que la sclérose en plaques, d'une infection ou d'une inflammation du système nerveux central, néoplasies, maladies non contrôlée de causes carentielles, toxiques ou métaboliques, trouble du sommeil majeur, épilepsie. - Antécédent de maladie psychiatrique majeure - Antécédent de traumatisme crânien majeur - Antécédent de chirurgie majeure (cœur, cerveau) - Traitement modifiant le métabolisme cérébral, en dehors des traitements de la sclérose en plaques - Patiente sans contraception, enceinte ou allaitante - État physique incompatible avec le protocole. |
