Aura is the term used to describe symptoms that may occur before a seizure. An aura may include:
- Visual changes. Examples include:
- Bright lights.
- Zigzag lines.
- Slowly spreading spots.
- Distortions in the size or shape of objects.
- Blind or dark spots in the field of vision.
- Hearing voices or sounds (auditory hallucinations).
- Strange smells (olfactory hallucinations).
- Feelings of numbness or tingling on one side of your face or body.
- Feeling separated from your body.
- Anxiety or fear.
An aura is often the first sign that you are going to have a seizure. You may have an aura from several seconds up to 60 minutes before a seizure. Most people who have auras have the same type of aura every time they have a seizure.
