What are aura spots in migraine?

Aura spots in migraines are visual phenomena that often precede a migraine attack. These neurological symptoms manifest as flickering lights, zigzag lines, blind spots or colour changes in the visual field. Aura spots typically last 5 to 60 minutes and can be a warning signal for an approaching migraine headache. This type of migraine is also called migraine with aura.

What exactly are aura spots and how do you recognise them?

Aura spots are visual disturbances that arise from temporary changes in brain activity. These phenomena usually start small and gradually spread across the visual field. The most common forms are flickering zigzag lines (also called fortification spectrum), blind spots, bright light flashes or coloured spots.

The symptoms can manifest in different ways. Some people see sparkling lights at the edge of their visual field, whilst others experience a growing blind spot that partially blocks vision. These visual phenomena may be accompanied by other aura symptoms, such as numbness in hands or face, speech problems or concentration difficulties.

Recognising aura spots is important because they are often a reliable predictor of an approaching migraine attack. By learning to recognise these migraine triggers, you can better prepare for the coming headache.

Why do you get aura spots before a migraine attack?

Aura spots arise from a neurological process called cortical spreading depression. This is a wave of electrical activity that slowly moves across the cerebral cortex and temporarily disrupts normal brain function. This electrical wave particularly affects the visual cortex, the part of the brain responsible for processing visual information.

During this process, blood flow and oxygen supply to certain brain areas change. The nerve cells respond by interrupting their normal activity, which results in the characteristic visual phenomena. These neurological changes then activate pain receptors and inflammatory processes that lead to migraine headache.

The exact mechanism of why some people experience aura with migraine whilst others do not is not yet fully understood. Genetic factors, hormonal changes and various migraine triggers may play a role in the development of this type of migraine.

How long do aura spots last and when do they disappear?

Aura spots typically last 5 to 60 minutes, with most episodes lasting between 15 and 30 minutes. The symptoms usually begin gradually, reach their peak and then slowly disappear again. In most cases, the visual phenomena completely disappear before the headache begins.

The progression of aura spots often follows a predictable pattern. They usually begin as a small disturbance in the visual field and spread out in a characteristic shape. The zigzag lines or light flashes often move from the centre to the outside of the visual field. Some people experience multiple aura episodes in succession before the headache develops.

After the aura spots disappear, there may be a period of 15 minutes to an hour before the headache begins. In some people, the headache occurs simultaneously with the aura, whilst others experience only aura without subsequent headache.

What can you do when you experience aura spots?

When you experience aura spots, it is important to rest and prepare for a possible migraine attack. Find a dark, quiet room and avoid bright lights or screens. Stop driving or other activities that require sharp vision until the aura has completely disappeared.

Practical migraine tips during an aura episode:

• Take preventive pain relief if this has been advised by your doctor
• Drink sufficient water to prevent dehydration
• Apply relaxation techniques, such as deep breathing
• Avoid known migraine triggers, such as strong odours or noise
• Note the time and characteristics of the aura for future recognition

Keeping a migraine diary can help recognise patterns and identify triggers. This makes it possible to take preventive measures and reduce the frequency of migraine attacks.

How chiropractic care helps with migraine and aura phenomena

Chiropractic treatment can be a valuable addition in reducing the frequency and intensity of migraines. Through spinal correction and improvement of nerve communication between brain and body, the body’s natural self-healing ability is supported. This holistic approach focuses on addressing underlying causes rather than just symptoms.

• Improvement of blood circulation to the brain
• Tension reduction in neck and shoulder muscles
• Preventive care to minimise migraine triggers
• A holistic approach to the nervous system

Many people experience a reduction in the frequency and intensity of migraines after regular chiropractic care. Through restoration of natural balance in the nervous system, aura phenomena can occur less frequently.
