Stroke – devastating but preventable

A stroke often has a sudden and devastating impact on quality of life.  However, the risk factors for stroke can usually be identified before it happens, and many treatments are known to decrease the risk.

Professors Anna Ranta, a neurologist and Ralph Stewart, a cardiologist, will discuss how to identify patients who have the greatest risk of stroke, how preventive treatments lower this risk, and how to individualise treatments so they are more likely to achieve the best outcomes for each patient. 

A particular focus of the presentation will be the management of atrial fibrillation both from a neurologist’s and a cardiologist’s perspective.
