The team involved scientists from the Royal College of Surgeons in Ireland (RCSI) and FutureNeuro, the SFI Research Centre for Chronic and Rare Neurological Diseases.
During the study, researchers found a pattern of molecules in blood that are higher in epilepsy patients before a seizure happens.
The molecules comprised fragments of transfer RNAs (tRNAs), which play a key role in building proteins within the cell.
