This activity is jointly sponsored by Medical Education Resources and National Stroke Association

Program Overview

Stroke is the leading cause of long-term severe disability and the fourth cause of death in the U.S.  Roughly 30-40% of first time strokes are cryptogenic, or due to unknown cause. It is necessary to establish the cause of stroke to determine functional prognosis, decrease the risk of future strokes, and select appropriate preventative care. Currently, serious gaps exist between in the clinical knowledge of cryptogenic stroke and how to treat, manage, and prevent the occurrence—leaving patients at risk for disabling strokes or even death.   

Goals and Learning Objectives

The goal of the Cryptogenic Stroke: Etiology, Diagnostics and Recurrent Preventative Management initiative is to educate healthcare professionals on cryptogenic stroke to ensure accurate diagnostic testing, diagnosis and treatment to prevent recurrent strokes. Through participation in this activity, learners should be able to:

  • Review the definition and frequency of cryptogenic stroke
  • Discuss  management options for recurrent stroke before cause of stroke is determined
  • Discuss diagnostic tests to monitor and test for cryptogenic stroke
  • Review evidence-based treatment options to repair Patent Foramen Ovale (PFO) and manage cryptogenic stroke to prevent recurrent stroke

Target Audience

The target audience for the Cryptogenic Stroke: Etiology, Diagnostics and Recurrent Preventative Management activity includes stroke nurse coordinators, neuroscience nurses and other nurses who work with stroke patients.
