Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Blood Oxygen Level Dependent functional MRI | There will be a unique MRI measurement for each participant. Group analyses presentation after 1 year. | We use 3 functional tasks using block paradigm: Object naming, Verbal generation and semantic judgment, to elicit BOLD response using fMRI in order to compare functional activation patterns between subjects. We also use hypercapnic challenge to elicit BOLD response in order to obtain Cerebral Vascular Reactivity properties of subjects. |
| Anatomical MRI | There will be a unique MRI measurement for each participant. Group analyses presentation after 1 year. | We use Voxel Based Morphometry to compare cortical volume (grey matter) between subjects. We also use tractography Diffusion Tensor Imaging to compare white matter properties between subjects. |
