E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
define the value of the load of amyloid protein studied with PET tracer [18F] Florbetaben in subjects with mild cognitive impairment (MCI), amnestic type with long disease duration (range 2-10 years) and imaging studies (MRI and / or [18F] FDG-PET) suggestive of involvement of the limbic / mesial temporal. |
|
E.2.2 | Secondary objectives of the trial |
correlate the amyloid load with neuropsychological measures, the clinical indices, the values of Aβ42, total tau and phospho-tau and with data from MRI and [18F] FDG-PET previously acquired for diagnostic purposes. |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
a) memory disorder in long-term prevalent and persistent; b) the long history of the disease (> 2) without features of progression; c) [18F] FDG-PET imaging for positive selective mesial temporal hypometabolism in the absence of the typical AD pattern (bilateral temporo-parietal hypometabolism). The clinical and neuropsychological investigations, CSF, [18F] FDG-PET and MRI will be done outside of this protocol, as patients are routinely subjected to such investigations in clinical diagnostic path at the centers of sending, in case of clinical suspicion of neurodegenerative disease. Will be enrolled only patients aged> 18 years.
All participants will be followed by a six-month clinical follow-up for at least 2 years in order to assess the possible clinical progression.
|
|
E.4 | Principal exclusion criteria |
focal brain disorders, physical, psychiatric or metabolic disorders that might otherwise explain the cognitive impairment |
|
