Scientists have discovered a pattern of molecules that appear in the blood before seizures which may lead to the development of an early warning system for epilepsy patients. FutureNeuro and Royal College of Surgeons in Ireland (RCSI) researchers have discovered molecules in the blood that are higher in people with epilepsy before a seizure happens. These molecules are fragments of transfer RNAs (tRNAs) a chemical closely related to DNA that performs an important role in building proteins within the cell. As per researchers involved in this study which was published in the Journal of Clinical Investigation tRNAs are cut
