Degenerative and vascular cognitive discorders
This team, made up of clinical and pre-clinical researchers, is multidisciplinary. It is located at the interface between neurology, pharmacology and imaging. The research project is focused on the translational, transnosographic and multimodal study of cognitive disorders associated with degenerative processes or neurovascular lesions, starting from the observation that the mechanisms are entangled.
- EMOTION & COGNITION
The study of the interaction between cognition and emotions allows us to better understand the expression of cognitive and emotional disorders frequently encountered in neurological and psychiatric pathologies. Thanks to the contribution of imaging techniques (fMRI and EEG), we aim to explore the neuroanatomical markers of the relationship between cognition and emotions in a transnosographic perspective. A first series of works will study the question of the increase of cognitive disorders by anxiety in neurovascular pathologies.

The work is based on data from local (STROKDEM) and international (STROKOG) cohorts and is under development. The first exploratory results have highlighted the involvement of a brain network specific to post-stroke anxiety involving the amygdala and the prefrontal cortex. The exploitation of these results is ongoing.
In the context of the management of post-stroke cognitive disorders, we will explore the brain bases of anxiety and attentional disorders using fMRI and EEG.
