Prodrome
Pronunciation: PROH-drohm
Early warning symptoms that may occur hours to days before a seizure, distinct from the immediate aura.
Full Definition
A prodrome refers to subtle behavioral, emotional, or physical changes that can precede seizures by hours or even days. Unlike an aura, which is technically part of the seizure itself and occurs immediately before or at seizure onset, prodromal symptoms are not considered part of the seizure. Common prodromal symptoms include mood changes, sleep disturbances, headaches, or increased irritability. Recognition of prodromal patterns can help patients and caregivers prepare for potential seizures and implement safety measures. Not all patients experience prodromal symptoms, and they are more commonly reported in complex partial seizures.
Usage
Usage note: Distinguish clearly from 'aura' which is part of the seizure itself.
