Children who suffer from strokes cost the US healthcare system at least $42m for their initial care, according to a new report in Stroke: Journal of the American Heart Association.

Researchers analysed data from US children aged zero to 20 who used hospital inpatient services to determine the costs of paediatric strokes in the US.

The lifetime costs of childhood stroke are probably more than that for adults because of longer life expectancy, which emphasises the greater need for preventing and treating stroke in children, researchers said.

The study found that costs were higher at government or public hospitals and urban teaching hospitals, as well as varying from region to region.
