Virchow-Robin Spaces: Correlations with Polysomnography-Derived Sleep Parameters |pdf=|usr=}}{{26163465}} gab.com Text Virchow-Robin Spaces: Correlations with Polysomnography-Derived Sleep Parameters JO: Sleep http://www.kidney.de/pget.php?&tw=1&pmid=26163465 #FOAvip Study Objectives:: To test the hypothesis that enlarged Virchow-Robin space volumes (VRS) are associated with objective measures of poor quality sleep. Design:: Retrospective cross-sectional study. Setting:: Sunnybrook Health Sciences Centre. Patients:: Twenty-six patients being evaluated for cerebrovascular disease were assessed using polysomnography and high-resolution structural magnetic resonance imaging. Measurements and Results:: Regionalized VRS were quantified from three-dimensional high-resolution magnetic resonance imaging and correlated with measures of polysomnography-derived sleep parameters while controlling for age, stroke volume, body mass index, systolic blood pressure, and ventricular cerebrospinal fluid volume. Sleep efficiency was negatively correlated with total VRS (rho = ?0.47, P = 0.03) and basal ganglia VRS (rho = ?0.54, P = 0.01), whereas wake after sleep onset was positively correlated with basal ganglia VRS (rho = 0.52, P = 0.02). Furthermore, VRS in the basal ganglia were negatively correlated with duration of N3 (rho = ?0.53, P = 0.01). Conclusions:: These preliminary results suggest that sleep may play a role in perivascular clearance in ischemic brain disease, and invite future research into the potential relevance of Virchow-Robin spaces as an imaging biomarker for nocturnal metabolite clearance.
