Auras, when they occur, allow some people who have epilepsy time to prevent injury to themselves and/or others when they lose consciousness.

The differential diagnosis of patients who experience symptoms of paresthesias, derealization, dizziness, chest pain, tremors, and palpitations can be quite challenging.

[2] An epileptic aura is the consequence of the activation of functional cortex by abnormal neuronal discharge.

[4][5] The most common auras include motor, somatosensory, visual, and auditory symptoms.

Complex visual auras can include people, scenes, and objects which results from stimulation of the temporo-occipital junction and is lateralized to one hemifield.

Auditory auras can also be simple (ringing, buzzing) or complex (voices, music).
