A Study to Assess Biomarkers of Cerebral Cavernous Angioma with Symptomatic Hemorrhage (CASH)

Overview

About this study

The purpose of this study is to develop prognostic and diagnostic blood tests for symptomatic brain hemorrhage in patients diagnosed with cavernous angiomas, a critical clinical challenge in a disease affecting more than a million Americans. We further examine whether blood biomarkers can replace or enhance the accuracy of advanced imaging in association with lesional bleeding. The project tests a novel integrational approach of biomarker development in a mechanistically defined cerebrovascular disease, with a clinically relevant context of use.
