Investigating the link between transient global amnesia and obstructive sleep apnea

PRevalence Of Transient Global Amnesia in Obstructive Sleep Apnea Syndrome

Observational University Hospital, Strasbourg, France · NCT06903026

This study is trying to see if people with obstructive sleep apnea are more likely to experience transient global amnesia, which could help find new treatment options.

What this trial studies

This observational study aims to explore the prevalence of transient global amnesia in patients diagnosed with obstructive sleep apnea syndrome. By analyzing a larger cohort of 200-250 patients, the study seeks to confirm or refute previous findings that suggested a potential association between these two conditions. The research will focus on understanding the underlying pathophysiological processes involved, which could lead to new therapeutic options. Participants will be recruited from the Neuropsychology Department of Strasbourg University Hospital based on specific inclusion criteria related to their amnestic episodes.

Who should consider this trial

Good fit: Ideal candidates include adults who have experienced an episode of transient global amnesia as defined by specific clinical criteria.

Not a fit: Patients with a history of recent head trauma or active epilepsy may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance our understanding of transient global amnesia and its relationship with sleep apnea, potentially leading to improved treatment strategies.

How similar studies have performed: Previous studies have suggested a link between obstructive sleep apnea and transient global amnesia, but this study aims to validate those findings on a larger scale.
