Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Amnesic stroke is an amnestic syndrome lasting less than 24 hours characterized by the occurrence of anterograde amnesia often associated with retrograde amnesia, the pathophysiology of which is still poorly understood at present. A recent study on a small sample size (N=29) highlighted an association between obstructive sleep apnea syndrome and amnesic stroke. Our study seeks to confirm or refute these results on a larger cohort (N=200-250). A better understanding of the pathophysiological processes involved would open up new therapeutic avenues.
