Brief Biography

Dr. deVeber is Director of the Children's Stroke Program, a Senior Scientist in the Child Health Evaluation Sciences Program and a paediatric neurologist in the Division of Neurology at The Hospital for Sick Children (SickKids), Toronto, Canada. In addition, Dr. deVeber is a  Professor of Paediatrics and a faculty member of The Institute of Medical Science at the University of Toronto. Her research focuses on stroke in newborns and children, defining the frequency, causes, treatments and outcomes of paediatric stroke.  She initiated and directs several large multi-centre collaborative studies including the Canadian Paediatric Ischemic Stroke Registry and the International Paediatric Stroke Study (IPSS), a large international study of childhood stroke with over 4,494 enrolled children at over 201 enrolling centres spanning 45 countries in Asia, Europe and North and South America.  The central organization and database reside at Sickkids.  In 2009, National Institutes of Health (NIH) funded Dr. deVeber as dual principal investigator with H. Fullerton in the USA to study childhood infection and stroke within the IPSS in a seven-year study.

Research Interests

Main interests: The International Pediatric Stroke Study (IPSS); Toronto Children’s Stroke Project and Canadian Paediatric Ischemic Stroke Registry

The Children’s Stroke Project consists of a number of inter-related studies of childhood stroke caused by blood clots. The Canadian Paediatric Ischemic Stroke Registry has studied stroke in more than 8,000 infants and children at the 16 children’s hospitals in Canada. Stroke affects 1 in 2,300 births in Canada. Our studies in SickKids children have defined important causes for stroke including chicken pox and anticardiolipin antibodies, a clotting problem. We are also studying treatments and outcomes. Our Stroke Outcome Study has found disability in over 40 per cent, recurrent events in 20 per cent and seizures and headaches in another 25 per cent. We are hosting and actively developing multinational studies of treatments for childhood stroke with collaborators in the UK, USA and other countries in the IPSS and it's NINDS funded sub-studies.

Research Activities

  • Risk Factors in paediatric stroke
  • Safety and feasibility of anticoagulation in paediatric ischemic stroke
  • Dose-finding and safety of tPA in childhood stroke
