Assessment of Emotional Memory During Transient Global Amnesia
- Conditions
- Amnesia, Transient Global
- Interventions
- Other: PET-CT examination
- Registration Number
- NCT04548037
- Lead Sponsor
- Centre Hospitalier Universitaire de Nīmes
- Brief Summary
There are few studies on the role played by emotions in transient global amnesia (TGA), in particular with regard to their impact on the functioning of memory. The study investigators wish to better understand the link between episodic memory, emotional state and psychogenic factors during TGA. It would be interesting to see if the patients suffering from TGA triggered by a psychological shock process emotional information differently from those whose TGA was triggered by an "organic" shock (physical effort, trauma, etc.). Finally, amnesic stroke is a good model for better understanding the function of the hippocampus, in particular of the CA1 region, in episodic memory.
