Evaluation of a Multimodal Neuroimaging Method for Diagnosis in Parkinsonian Syndromes
This trial is active, not recruiting.
|Conditions||parkinson's disease, multiple system atrophy|
|Treatments||mri acquisition, behavioral evaluations|
|Sponsor||Institut National de la Santé Et de la Recherche Médicale, France|
|Start date||January 2013|
|End date||June 2016|
|Trial size||60 participants|
|Trial identifier||NCT02428816, 2012-A01252-41, C12-52|
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.
|Intervention model||parallel assignment|
The primary outcome measure to discriminate individual patients and patients with MPI and AMS through multimodal MRI isolating multiparametric spatial signature resulting from a combination of markers in multimodal imaging.
time frame: 1 year
correlate MP and MSA disease severity with extracted multimodal MRI biomarkers in whole brain
time frame: 1 year
Male or female participants from 18 years up to 80 years old.
- informed consent signed
- right handed patients
- Mini Mental Score > 22
- no other neurological disease than Parkinson's Disease (PD) or Multiple System Atrophy (MSA)
- non-demented patients reached by PD or MSA (according to diagnosis criteria from UK PD Brain Bank and from Gilman and colleagues, 1998, for PD and MSA respectively)
- for PD patients only : Hoehn and Yahr score from 2 to 3
- contraindications to MRI (cardiac or auditive prothesis, pacemakers, cerebral clip, stimulating electrodes)
- pregnant women
- major neuropsychiatric disease
- refusal to be informed in case of cerebral anomaly detected during MRI acquisition
- uncompensated thyroid deficit
|Official title||Evaluation and Validation of a Multimodal MRI Neuroimaging Method: Application to Differential Diagnosis and Disease Progression in Parkinsonian Syndromes|
|Principal investigator||Olivier Rascol, Pr|
|Description||30 patients with PD and 30 patients with MSA 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.|
