What this trial studies

This study aims to evaluate the potential precipitating and risk factors associated with Reversible Cerebral Vasoconstriction Syndrome (RCVS) through a prospective selection of well-characterized patients and controls. It will assess the impact of these factors on patient prognosis via follow-up evaluations. Additionally, the study will establish a clinicoradiological database and a biobank containing plasma, cerebrospinal fluid, and DNA for future multicenter research on RCVS. The study is designed as a monocentric analytic observational case-control study with interventional elements due to the collection of biological samples.

Who should consider this trial

Good fit: Ideal candidates include men and women aged 18 and older diagnosed with RCVS or suspected RCVS within 14 days prior to inclusion.

Not a fit: Patients with severe neurological conditions, coma, or those unable to provide informed consent may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to better understanding and management of RCVS, potentially improving patient outcomes.

How similar studies have performed: While this study explores a novel approach to understanding RCVS, similar studies have shown promise in identifying risk factors for other neurological conditions.
