Overview
Brief Summary
Based on previous promising results, the next step for the validation of a multimodal MRI method in diagnosis and follow up of patients reached by parkinsonian syndromes is (i) to test whether the multimodal neuroimaging is able to discriminate at the individual level, patients with multiple system atrophy parkinsonism (MSA) and patients with idiopathic Parkinson's disease (PD) (ii) to determine whether the method is sensitive to measure changes over time for the two diseases, according to imaging, neuropsychological and other clinical data. Patients will be compared with healthy controls.
Detailed Description
30 patients with PD, 30 patients with MSA and 30 healthy controls will be examined in a 3Tesla MRI. The aim of our project is to demonstrate that our multimodal MRI method can discriminate both diseases with a similar clinical presentation and monitor the progress of the disease. CIC's expertise in recruitment and assessment of patients, and the powers of the INSERM U825 in terms of development and processing in neuroimaging guarantee the feasibility of the project and its successful completion.
