Childhood stroke affects up to 13 out of every 100,000 children a year in the UK.
The Stroke Association funded Dr Finbar O'Callaghan to conduct research into childhood stroke, which was recently published in the medical journal, Lancet Neurology.
The study looked at how often arterial ischaemic stroke (AIS) occurs in children. AIS happens when the blood flow to the brain is blocked. This could be because an artery becomes too narrow or because a blood clot forms, blocking the supply of blood to a part of the brain.
The researchers compared different groups of children to investigate whether the risk of AIS was different between them and why this may be.
They found that the age of a child and their racial group were both factors that affect the risk of AIS.
Black and Asian children were found to be at a higher risk when compared to white children, and the highest risk was found in babies under a year old. They also found that the risk was the same in both male and female children.
We hope this important study will lead to further research to explain what factors increase the risk of childhood stroke and what may be done about them.
In collaboration with the Evelina London Children’s Hospital, the Stroke Association also runs the Childhood Stroke Project to support families affected by childhood stroke.
