What is an aura?

• A. Foreknowledge that a seizure is going to occur
• B. A sensation that immediately precedes sleep
• C. A post-seizure state of confusion
• D. A general feeling of fatigue

Answer: (A)

An aura is a warning sign that occurs right at the start of a seizure. It’s a subjective experience that the person feels or notices before the seizure fully begins—often a strange smell or taste, a unusual sensation in a limb, or a feeling of déjà vu. This foreknowledge helps distinguish an aura from other states because it signals the upcoming ictal event. It isn’t a sensation that happens before sleep, which would be more like a hypnagogic moment. It isn’t the confusion or disorientation that occurs after a seizure (post-ictal state), and it isn’t simply fatigue.
