PET Study With 11 C-PIB to Evaluate Amyloid Protein Deposits in Mild Cognitive Disorder, Alzheimer's Disease and Early Frontotemporal Degeneration.

Preclinical and clinical data have demonstrated the ability of the 11C-PIB tracer to selectively bind accumulations of amyloid protein, a neuropathological marker characteristic of the neurodegenerative pathologies covered by this study. The validation in larger groups of patients, and the comparison between the different clinical syndromes included in the spectrum, will allow the diagnostic and prognostic potential of the tracer to be evaluated, with important consequences for the clinical management of patients. In particular, the tracer could play a central role in the clinical management of patients with neurodegenerative diseases and cognitive impairment. Numerous pharmacological trials are currently underway, worldwide, for the validation of anti-amyloid drugs. In the future we could think about early monitoring with imaging of the effectiveness of the treatment. T he FDG PET technique can be of great help in obtaining relationships between radiation damage to the brain and possibly neurological and neuropsychological deficits associates.
