Brief summary
Development of a shared multimodal MRI protocol for the definition and quantification of imaging biomarkers in AD, DLB, FDT dementias, especially white matter alterations.
Detailed description
Development of a shared multimodal MRI protocol for the definition and quantification of imaging biomarkers in AD, DLB, FDT dementias, especially white matter alterations.
Interventions
DIAGNOSTIC_TESTAD FDT DBL GROUP
All participants will undergo an MRI session. The MRI protocol will include the clinical diagnostic protocol defined within the Network and research sequences as specified above (T1 3D, DTI, FLAIR 3D, QSM).

Inclusion criteria
for patients * accident cases * time of onset of NOT MORE THAN 24 months * Clinical Dementia Rating Scale (CDR) \<=2; * MoCA\<=17 for controls absence of complaints of cognitive disorders and/or neurological/neuropsychological visits for the evaluation of such disorders; * CDR = 0; * MoCA\>=27. for all Age \>= 50 and \<= 80; * Hachinski Ischemic Scale - 7 items \< 2; * visual and/or auditory acuity sufficient to carry out the neuropsychological assessment; * if on neuropsychopharmacological therapy, stability for 4 weeks before the start of the study.
Exclusion criteria
for all * any uncontrolled medical condition or neurological/neurodegenerative disease that, in the opinion of the recruiting physician, could contribute to the individual's cognitive impairment \[e.g., kidney disease, liver disease, brain tumor, alcohol or drug abuse, abnormal thyroid function, hydrocephalus normotensive, vascular dementia, neurocognitive disorder due to head trauma (according to the diagnostic criteria of the DSM V)\]; * transient ischemic attack or stroke during the 12 months preceding screening; history of unstable angina, myocardial infarction, heart failure (New York Heart Association Class III or IV), or clinically significant heart rhythm disturbances documented within one year of screening; * history of malignant tumor disease, except: cancer in remission for more than 5 years since screening; prostate cancer in situ; * history of surgically treated squamous cell carcinoma or basal cell carcinoma; * impaired liver function or liver failure; * history or evidence of autoimmune disease considered clinically significant by the doctor or requiring the chronic use of corticosteroids or other immunosuppressive drugs; * clinically significant systemic illness or infection within 30 days of screening; comorbidity for primary psychiatric or neurological disorders; * absence of an informant (partner, relative, adult child or friend) who knows the subject well enough to be able to provide reliable information on his cognitive and functional abilities. * contraindication to carrying out the MRI exam.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Quantitative Susceptibility Mapping (QSM), Diffusion Weighted Imaging (DWI) - Diffusion Tensor Imaging (DTI), Fluid Attenuated Inversion Recovery (FLAIR) | during MRI procedure | The main endpoint is the characterization of white matter alterations in different forms of dementing diseases through the combined study of MRI sequences. Specifically, we correlate Voxel Based Morphometry indices, DTI quantifcation and lesions volume with MMSE and MOCA scores. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| FLAIR, QSM, DWI (DTI) for white matter study | during MRI procedureRMN date examination | Quantitative analysis of FLAIR, QSM, DWI (DTI) for white matter evaluation ES2. Characterization of white matter alterations which will also take place through the quantification of: * microstructure and macrostructure values of the white matter through diffusion techniques (including DTI) * white matter lesions through post-processing algorithms (14) applied to the FLAIR sequence; * magnetic susceptibility in the white matter and in particular in myelin (15), through the QSM technique; ES3. Definition of an automatic single-case multimodal algorithm (MUQUBIA) for the quantification and classification of subjects with alterations of the white matter (as emerged from MRI data) useful for doctors in the Network. ES4. Evaluation of variables of interest emerging from MRI analyzes in relation to clinical and neuropsychological variables |
