Is an aura considered a seizure? Some patients have an unusual sensation or feeling, known as an aura, that alerts them to an upcoming seizure before it happens. The aura is actually a simple focal seizure, also known as a partial seizure. These types of seizures only affect a small part of the brain and only occur in one side of the brain.
Do auras show up on EEG?
Our study showed that EEGs of patients with visual auras had abnormal discharges not only in the occipital lobe but also in the frontal and parietal lobes. This confirmed the findings from previous studies, which suggested that visual auras were suggestive of ictal onset from the occipital or temporal lobe.
What types of seizures have auras?
An ‘aura’ is the term that some people use to describe the warning they feel before they have a tonic clonic seizure. An epilepsy ‘aura’ is in fact a focal aware seizure.

Do auras damage the brain?
The results of the study revealed that those who had migraines with aura showed a 68% increased risk of white matter brain lesions, compared with those who did not have migraines. Patients who experienced common migraines showed a 34% increased risk of brain lesions compared with those not suffering from migraines.

Can memories trigger seizures?
In humans, we propose that such triggering stimuli can be revived by memory alone. Thus, individualized stimuli can trigger partial limbic seizures or seizure-like bizarre episodes with a transient loss of frontal control functions.
Can you fight off a seizure?
In cases where the aura is a smell, some people are able to fight off seizures by sniffing a strong odor, such as garlic or roses. When the preliminary signs include depression, irritability, or headache, an extra dose of medication (with a doctor’s approval) may help prevent an attack.

How common is visual aura?
Visual aura symptoms (VASs) are by far the most common and occur in 98–99% of MAs, whereas disturbances of sensation and language occur in 36% and 10% of auras, respectively . In addition to being the most common aura symptoms, VASs are also the most multifaceted.
What happens in the brain during a migraine aura?
The result: The brain produces an outsize reaction to the trigger, its electrical system (mis)firing on all cylinders. This electrical activity causes a change in blood flow to the brain, which in turn affects the brain’s nerves, causing pain.
