aura
A subjective sensory, motor, or psychic phenomenon that precedes or accompanies a seizure, particularly in focal epilepsy.
Full Definition
An aura represents the initial manifestation of a focal seizure, often serving as a warning sign before more obvious seizure activity. Common types include visual auras (flashing lights, scotomas), auditory auras (buzzing, music), olfactory auras (unpleasant smells), gustatory auras (metallic tastes), and psychic auras (déjà vu, fear, euphoria). The specific characteristics of auras can help localize the seizure focus within the brain and guide treatment decisions.
Usage
Usage note: In neurology, distinct from migraine aura; specify type and duration for seizure documentation.
