An aura can be the first sign that an epileptic seizure is about to happen. An epilepsy aura is also called a focal aware seizure. These focal aware seizures, or auras, typically happen less than a minute before a tonic-clonic seizure — auras can develop into a more serious seizure. Focal seizures, such as focal aware seizures, tend to start in one specific area of the brain (even if they spread). This might explain the sensations associated with auras.
