An aura is a sensory perception experienced by some people before a seizure. It is a warning sign that can affect the individual’s vision, touch, smell, sound, or taste. It is sometimes called an “alarm bell” warning of an impending seizure.

The exact cause of an aura is unknown, but it is believed to be related to the brain’s electrical activity. Some researchers believe that it is caused by abnormal electrical activity in the brain that produces a feeling of unease or a warning sign. This abnormal electrical activity may be related to an imbalance in the brain’s neurotransmitters, such as serotonin or dopamine.

Aura is a common symptom of epilepsy but can also occur in those without epilepsy. In addition, it can occur in people with other neurological conditions, such as migraine. However, it is essential to note that not everyone with epilepsy will experience an aura.

Auras can be described in many different ways. Individuals need to be aware of their aura and how it feels. Common descriptions of an aura include fear, apprehension, uneasiness, a tingling sensation, or a feeling of déjà vu. Some individuals may also see lights or shapes, feel a sense of numbness, or experience auditory or olfactory (smell) hallucinations.

If you are experiencing an aura, it is essential to reduce the seizure risk. This can include avoiding triggers that may cause the aura, such as stress, lack of sleep, or certain medications. In addition, it is crucial to speak with your doctor if you are experiencing auras, as medications can help prevent or lessen the severity of seizures.
