ASA is currently planning this meeting to be an in-person event AND a virtual event. We have multiple new abstract categories this year including:

  • COVID-19
  • Brain Health
  • Neuroendovascular
  • Advanced Practice Providers
  • Translational Basic Science

We welcome abstracts from all areas of the stroke and brain health medical fields.

Why you should attend #ISC21

The International Stroke Conference is the world’s premier meeting dedicated to the science and treatment of cerebrovascular disease. From forming multiple, life-long collaborations with the best minds in the profession to hearing the very latest big trial results to the exceptional education and science, if you are involved in the stroke medical profession, ISC is essential to your career.

This 2½-day conference features more than 1,700 compelling presentations in 21 categories that emphasize basic, clinical and translational sciences as they evolve toward a better understanding of stroke pathophysiology with the goal of developing more effective therapies.

This conference provides the opportunity to network with thousands of colleagues in the stroke field from around the world with wide-ranging expertise and experience.

Clinical Sessions focus on community risk factors; emergency care; acute neuroimaging; acute endovascular and acute nonendovascular treatment; diagnosis of stroke etiology; cerebral large artery disease; in-hospital treatment; clinical rehabilitation and recovery; and health services, quality improvement, and patient-centered outcomes.

Basic Science Sessions focus on vascular biology in health and disease; basic and preclinical neuroscience of stroke recovery; and experimental mechanisms and models. Further specialized topics include pediatric stroke; intracerebral hemorrhage; nursing; preventive strategies; vascular cognitive impairment; aneurysms; subarachnoid hemorrhage; neurocritical care; vascular malformations; and ongoing clinical trials.

Presentations on these topics attract a wide range of healthcare professionals and investigators including adult and pediatric neurologists; neurosurgeons; neuroradiologists and interventional radiologists; physiatrists; emergency medicine specialists; primary care physicians; hospitalists; nurses and nurse practitioners; rehabilitation specialists; physical, occupational, and speech therapists; pharmacists; and basic researchers spanning the fields of cerebrovascular function and disease.
