Migraine Aura

What Migraine Aura Is

Aura shows up across several sensory domains. Visual aura, the most common form, is described as bright lines, geometric shapes, scintillating (shimmering) spots, or areas of vision loss that move across the visual field.^[1] Sensory aura is tingling or numbness that spreads through a limb or across the face, and aura can also affect language or hearing, producing word-finding difficulty or ringing in the ears.^[1] The research distinguishes positive symptoms, like the shimmering lines of visual aura, which come from active neural firing, from negative symptoms, like vision loss or numbness, which come from a loss of function in that same circuit.^[1]

The proposed mechanism behind aura is cortical spreading depression, a self-propagating wave of neuronal and glial depolarization that moves slowly across the outer surface of the brain.^[1] A widely cited review of migraine pathophysiology describes that wave as capable of activating the trigeminovascular pathway, the nerve network thought to connect brain-surface events like aura to the headache phase that often follows.^[2]

How It's Logged

There's no device that detects aura. It's a self-reported, dated log: which type of aura happened, roughly how it presented, and whether a headache followed, which turns a fast, disorienting event into a record you can look back on.

Why People Track Migraine Aura

Aura is easy to log in the moment and easy to forget the details of later, since it typically resolves within the hour and doesn't leave a physical mark. A dated record of what type of aura happened and when keeps that detail rather than relying on memory weeks later.

Aura is also logged separately from headache and migraine intensity, so the two can be looked at both together and apart. For how headache and migraine timing relates to the menstrual cycle, see the headaches & migraine entry.

How Go Go Gaia Tracks Migraine Aura

Go Go Gaia has a dedicated 1-click log for aura symptoms, kept separate from the headache and migraine severity logs. Every entry is charted against your cycle phase alongside everything else you track, so a pattern in aura timing becomes visible as a repeating shape across cycles.

What the Research Shows

Overall migraine prevalence is estimated at 12% to 15% of the general population, with a marked gender gap: roughly 17% of women versus 6% of men report an attack in a given year.^[1] Aura accompanies an estimated 25% of migraine cases, and onset tends to increase up to ages 35 to 39 before declining.^[1]

For how the timing of migraine attacks, aura included, relates to the menstrual cycle, see the research summarized in the headaches & migraine entry, which covers the estrogen-withdrawal research behind menstrual migraine in more depth.

Frequently Asked Questions

What is migraine aura?

Migraine aura is a fully reversible set of neurological symptoms that develops gradually, typically over minutes, and usually lasts under an hour.^[1] It can happen before or alongside a migraine headache, and research estimates it affects close to a quarter of people with migraine.^[1]

What does visual aura look like?

Visual aura is the most common type, described in the research as bright lines, shapes, scintillating (shimmering) spots, or areas of vision loss.^[1] It typically develops gradually and moves across the visual field before resolving.

What causes migraine aura?

The proposed mechanism is cortical spreading depression, a self-propagating wave of neuronal and glial depolarization that moves slowly across the surface of the brain.^[1] That wave is thought to activate trigeminal nerve fibers, which is part of the broader picture connecting aura to the headache phase of migraine.^[1]
