Diagnosing and treating stroke as quickly as possible is important, to minimise avoidable brain damage. Researchers have devised an experimental prototype helmet using microwave technology which can distinguish between bleeds (haemorrhagic stroke) and clots (ischaemic stroke) quickly, so potentially permitting earlier treatment; for example pre-hospital thrombolytic treatment. The accuracy of diagnosis is not yet 100%, so this device needs further development and testing.
