Sleep-Related Determinants of Stroke

Overview

About this study

Stroke is the second leading cause of death worldwide. Traditional stroke risk factors explain about half of the risk for stroke. The remaining half may be partially explained by sleep duration and disturbances, which are prospectively related to incident stroke across multiple populations. Although these relationships have been identified, at present, essentially nothing is known regarding the modifiable, sleep-inhibiting behaviors that determine sleep duration and disruption; these are probable targets of stroke prevention. The study proposed here is intended to fill this void by determining the relation between sleep-inhibiting behaviors, self-reported sleep duration and disruption, and stroke amongst acute stroke inpatients.

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate.
