Which of the following best describes the aura phase of a seizure?

• A. Alterations in smell, taste, or vision
• B. Loss of consciousness with generalized convulsions
• C. Postictal confusion
• D. Abdominal pain

Answer: (A)

Aura is a sensory warning sign that some people experience before a focal seizure. It commonly shows up as alterations in smell, taste, or vision, which reflect seizure activity in specific brain areas—the olfactory cortex for smells, the gustatory areas for taste, and the visual cortex for vision. This makes the description of sensory changes the best way to characterize the aura phase. It isn’t describing a generalized seizure with loss of consciousness and widespread convulsions, nor the postictal state that comes after a seizure ends. Abdominal sensations can occur in some temporal lobe seizures, but the classic aura is best captured by sensory changes like smell, taste, or vision.
