What term describes a pre-seizure experience that may warn a person that a seizure is starting?

• A. Aura
• B. Seizure
• C. Postictal confusion
• D. Epilepsy

Answer: (A)

An aura is a brief, subjective sensation that occurs at the start of a focal seizure and can warn a person that a seizure is beginning. Because it arises from electrical activity in a specific brain area, the experience varies: it might be visual changes like flashing lights, a smell or taste that isn’t present, a feeling of déjà vu, sudden fear or nausea, or odd numbness or tingling. For many people, the aura acts as a warning sign they can recognize, allowing them to sit down safely or use prescribed rescue meds. This is distinct from a full seizure, which is the actual event that may involve loss of awareness or convulsions. The postictal period comes after the seizure, during which confusion or sleepiness can occur. Epilepsy is the broader condition characterized by recurrent seizures.
