Aura is the term used to describe symptoms that may occur before a seizure. An aura may include:
Visual changes. Examples include:
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.
