E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To study cerebral synaptic loss with PET and [18F[UCB-H as a very early marker of neurodegenerative cognitive disorder, according to their brain amyloid load studied with PET and [18F]flutemetamol |
Etudier la perte synaptique cérébrale en TEP avec le radiotraceur [18F]UCB-H, comme marqueur très précoce d'un trouble cognitif neurodégénératif, en fonction de leur charge cérébrale en amyloide, mesurée par TEP et [18F]flutemetamol |
|
E.2.2 | Secondary objectives of the trial |
To compare PET and MRI as early biomarkers of synaptic loss in neurodegenerative cognitive disorder |
Comparer les techniques de TEP et de RMN comme marqueur précoce de perte synaptique dans les troubles cognitifs neurodégénératifs |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
Healthy eledrly participants (50 to 90 years old), with and without cognitive complaints, with neuropsychological performance in the normal range. A relative is available to provide information on cognitive functioning of the participant. |

E.5 End points |
E.5.1 | Primary end point(s) |
We hypothesize to find negative correlation between the severity of subjective memory complaints and synaptic activity, and a positive correlation between memory test results (withing the range of normality) and synaptic activity in the MTL. Data will be analysed in « amyloid-positive » and « amyloid-negative » participants, and changes over 18 months will be analysed, looking for evolution of synaptic loss according to initial synaptic density and brain amyloid accumulation |
Relations entre plaintes cognitives et performance cognitive et la densité synaptique dans le lobe temporal médial. Les résultats seront stratifiés en fonction de la charge amyloide cérébrale. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
(1) Acquisition of data for 50 participants, (2) last inclusion in the trial (T1) and (3) last follow-up visit (T2) |
Acquisition des données pour 50 participants, dernière inclusion dans l'étude (T1) et dernière visite de suivi (T2) |
|
E.5.2 | Secondary end point(s) |
As second end point, we will search for a possible influence of MRI measures on the previous relationship, looking for mediation of remote connectivity between MTL and other brain structures (for example in the default mode network) to influence subjective awareness of cognitive decline and possible cognitive performance. |
Influence des mesures de neurodégénérescence et de connectivité obtenues en IRM sur la conscience des troubles et les performances cognitives |
