About migraine with aura

An aura is a set of neurological symptoms you may get as part of a migraine attack. Neurological means it’s related to the nervous system. If you have migraine, you may get migraine attacks with aura or without aura. You can get both types of attacks at different times. Up to a third of people with migraine get migraine attacks with aura.

Aura symptoms

Auras are most commonly to do with your sight. The common symptoms related to your sight include:

• blind spots
• blurred vision
• seeing coloured spots or lines
• seeing flashing or flickering lights
• seeing zig zag patterns.

Other aura symptoms can include:

• numbness or tingling sensation like pins and needles in parts of your body
• problems with speech
• feeling dizzy
• muscle weakness.

Muscle weakness is a less common symptom of aura. If you experience this for the first time, seek medical advice.

Auras usually start happening gradually over about five minutes. Aura symptoms usually last from five minutes up to an hour. The symptoms are temporary, so will wear off after this time. Subtypes of migraine with aura include migraine with brainstem aura, hemiplegic migraine and retinal (or ocular) migraine.

Headache stage in migraine with aura

For most people who get migraine with aura, the aura usually happens just before the main attack stage. This is when you typically get a headache and other migraine symptoms, like sickness and sensitivity to light or sounds.

Some people experience aura symptoms throughout a migraine attack, or after a headache has begun.

Silent migraine

Some people have aura symptoms but don’t get a headache. This is sometimes referred to as a ‘silent migraine’ or as migraine aura without headache.

Silent migraine is more common in older people. You may be more likely to get it if you develop migraine later in life. If you had typical migraine with aura (with headache) when you were younger, you may also progress to silent migraine as you get older.

Causes of migraine with aura

It is not known exactly what causes auras.

Scientists have looked into it and found that it may be caused by a slow wave of altered brain activity called ‘cortical spreading depression’. This leads to temporary changes in the chemicals, nerves and blood flow in the brain that affect how it works and could be related to pain.

Treatment options for migraine with aura

Your treatment options depend on how often you have attacks and how severe they are. It will also depend on other factors such as other illnesses you may have or medication that you take.

Generally, treatment for migraine includes:

• Acute treatment such as over-the-counter painkillers, migraine-specific treatments (triptans) and anti-sickness medication. These treatments aim to help manage the symptoms when an attack comes on. For migraine with aura, you should take them as soon as a headache starts. If you only get aura and no head pain, talk to your GP, as this type of treatment won’t work for you. There are no treatments specifically to help with the aura alone. Be careful not to take certain acute treatments on too many days a month as this can cause medication overuse headache.
• Preventive treatment such as beta-blockers, tricyclic antidepressants or anti-epilepsy drugs. These treatments aim to reduce how often you have migraine attacks and how bad they are. You usually take them every day and build them up to an effective dose. Some people need to try a range of treatments or may be referred to a specialist if the treatments don’t work for them.

Alongside the treatments many people benefit from reviewing whether lifestyle changes can help with their migraine attacks. This can include things like sticking to a routine, waking up at the same time each day, eating at similar times each day and staying hydrated. If there are factors such as alcohol or lack of sleep that seem to trigger your migraine attacks, there might be changes that you can make to help reduce how often you have attacks.
