Conditions

Alzheimer Disease

Brief summary

The aim of this study is to understand regional variations in acetylcholine esterase activity in Alzheimer's disease. In this study the aim is to identify by PET the physiological values of the regional activity of acetylcholine esterase using the 11C PM4 tracer and to study by PET and 11C PM4 the brain activity of acetylcholine esterase in a group of patients with Alzheimer's disease, enrolled according to the inclusion and exclusion criteria. The PET data will be correlated with the clinical, neuropsychological and morphological data acquired by MRI and with the clinical-cognitive outcome.

Interventions

DIAGNOSTIC_TESTPET with 11C MP4

Each subject will undergo a PET exam using 11C MP4 as a tracer. This is a specific ligand for the acetyl-choline esterase enzyme already used abroad both in healthy volunteers and in various patient groups.
