Migraine aura can involve temporary changes in vision, sensation or speech. Some people see flashing lights or zigzag lines. Others notice tingling or difficulty finding words. Aura can happen before a headache, during it or without a headache. A record of the timing and symptoms can help your doctor assess what happened.
Do not assume a new neurological symptom is aura because you have had migraine before. Sudden weakness, trouble speaking or vision loss needs urgent medical assessment. If symptoms could be a stroke, contact local emergency services immediately and do not delay care to complete a diary.
What does migraine aura feel like?
Visual symptoms are common, but aura is not limited to vision. The International Headache Society’s aura criteria include fully reversible visual, sensory and speech or language symptoms, alongside other aura types.
Typical aura often develops gradually. Individual symptoms commonly last 5 to 60 minutes. That timing is one part of a clinical assessment, not a test you should use to rule out an emergency. Several symptoms may occur in sequence. Some aura types have different timing.
A blurry screen alone does not establish aura. Light sensitivity and aura are also different experiences, although they can occur in the same person.
What should you record after a possible aura?
Once you are safe and able to write, note:
- Start and end time. Use approximate times if needed.
- What changed. Describe flashes, missing areas of vision or tingling in your own words.
- How it developed. Did it begin suddenly or spread over several minutes?
- Which areas were affected. Note one side or both sides and whether symptoms seemed to involve one eye or both.
- Other symptoms. Include headache, nausea or trouble speaking.
- How it compares with previous episodes. A new pattern matters even if it later resolves.
Do not try to provoke symptoms or repeat visual checks while driving. Stop driving safely if your vision is affected and get help.
A useful note is more than the word “aura”
An example might read:
Around 10 am, a small zigzag shape appeared in my vision. It expanded over several minutes and faded after about 25 minutes. A headache followed. This looked similar to my previous episodes.
This example illustrates a description. It does not confirm a diagnosis. A clinician can make better use of that account than a label without timing or detail.
If you use Cephala, you can add the description to an attack note once you feel ready. Do not describe an entry as a confirmed aura unless your clinician has assessed it.
When should you seek urgent help?
The NHS migraine guidance lists sudden extremely painful headache, problems speaking, vision loss and other neurological symptoms as reasons for emergency help. New weakness, confusion or a seizure also needs urgent attention.
Symptoms that last longer than your usual episodes or differ from your established pattern deserve prompt medical advice. Do not wait for an arbitrary duration to pass before seeking help. Even symptoms that resolve may need assessment.
Common questions
Can aura happen without headache?
Yes. However, a first episode or a changed pattern should be assessed rather than self-diagnosed from an online description.
Is light sensitivity the same as aura?
No. Light sensitivity means light feels uncomfortable or worsens symptoms. Aura involves temporary neurological symptoms. Read more about migraine and light sensitivity.
Should I time an episode before calling for help?
No. Emergency care takes priority. Write what you remember after you are safe. Our migraine diary guide explains how to mark uncertain details.
