An aura is a perceptual disturbance experienced by some with migraines or seizures.
Up to one-third of people have an aura: typically a short period of visual disturbance that signals that the headache will soon occur.

Epileptic seizure

An aura is a perceptual disturbance experienced by some with migraines or seizures.
Focal seizures are often preceded by certain experiences, known as an aura.

Epilepsy

epilepticseizure disorderepilepsies
The aura stage precedes a generalized or grand mal seizure in epilepsy, as the side-effects of a focal seizure(s) or petit mal(s) which may or may not be followed by a generalized or grand mal seizure or seizures, but can happen at any stage of a migraine.
Focal seizures are often preceded by certain experiences, known as auras.

Acephalgic migraine

migraine aura without headachepersistent visual aura without headachesilent migraine
Some people experience aura without a subsequent migraine or seizure (see silent migraine).
It is a relatively uncommon variant of migraine in which the patient may experience aura, nausea, photophobia, hemiparesis, and other migraine symptoms, but does not experience headache.

Generalized tonic–clonic seizure

tonic-clonic seizuregrand maltonic-clonic seizures
The aura stage precedes a generalized or grand mal seizure in epilepsy, as the side-effects of a focal seizure(s) or petit mal(s) which may or may not be followed by a generalized or grand mal seizure or seizures, but can happen at any stage of a migraine.
This type of prodrome is distinct from stereotypic aura of focal seizures that become generalized seizures.

Scintillating scotoma

Scintillating scotoma is a common visual aura that was first described by 19th-century physician Hubert Airy (1838–1903).

Focal seizure

complex partial seizurepartial seizurepartial seizures
The aura stage precedes a generalized or grand mal seizure in epilepsy, as the side-effects of a focal seizure(s) or petit mal(s) which may or may not be followed by a generalized or grand mal seizure or seizures, but can happen at any stage of a migraine.
When this is the case, the focal aware seizure is usually called an aura.

Scotoma

Scintillating scotoma is a common visual aura in migraine.

Abdominal aura

abdominal sensations
Abdominal aura (also known as visceral aura and epigastric aura) is used to denote a type of somatosensory or somaesthetic aura that typically manifests itself as a rising epigastric sensation.

Generalized epilepsy

The aura stage precedes a generalized or grand mal seizure in epilepsy, as the side-effects of a focal seizure(s) or petit mal(s) which may or may not be followed by a generalized or grand mal seizure or seizures, but can happen at any stage of a migraine.

Absence seizure

The aura stage precedes a generalized or grand mal seizure in epilepsy, as the side-effects of a focal seizure(s) or petit mal(s) which may or may not be followed by a generalized or grand mal seizure or seizures, but can happen at any stage of a migraine.

Panic attack

Auras can also be confused with sudden onset of panic, panic attacks or anxiety attacks, which creates difficulties in diagnosis.

Differential diagnosis

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

Motor cortex

If the motor cortex is involved in the overstimulation of neurons, motor auras can result.

Primary somatosensory cortex

somatosensory cortexAreas 3, 1 and 2Brodmann areas 3, 1 and 2
When the primary somatosensory cortex is activated, more discrete parts on the opposite side of the body and the secondary somatosensory areas result in symptoms ipsilateral to the seizure focus.

Visual cortex

primary visual cortexstriate cortexV1
Simple visual symptoms can include static, flashing, or moving lights/shapes/colors caused mostly by abnormal activity in the primary visual cortex.

Auditory cortex

primary auditory cortexauditoryauditory processing
Simple symptoms can occur from activation in the primary auditory cortex and complex symptoms from the temporo-occipital cortex at the location of the auditory association areas.
