"Zigzag migraine" is not a recognized medical term. However, it's likely you're referring to a specific type of migraine aura known as fortification spectra.
What are Fortification Spectra?
Fortification spectra are visual disturbances that occur before or during a migraine attack. They are often described as:
- Zigzag lines: These lines appear to be jagged or wavy and may move across the field of vision.
- "Fortifications": This term refers to the way the lines often resemble a series of ramparts or fortifications.
- Expanding or shrinking: The lines may appear to expand outward from a central point, or shrink inward.
- Flickering or shimmering: The lines may also flicker or shimmer, and their appearance can change rapidly.
How do Fortification Spectra Feel?
People experiencing fortification spectra often describe them as:
- Seeing "stars" or "sparkles"
- Feeling like a "wave" is moving across their vision
- Having a blind spot in their vision
- Experiencing a temporary loss of vision
What Causes Fortification Spectra?
Fortification spectra are thought to be caused by abnormal electrical activity in the visual cortex of the brain. This activity can disrupt the normal processing of visual information, leading to the distorted visual perceptions.
Are Fortification Spectra Serious?
Fortification spectra are not usually a cause for concern and are a common symptom of migraine with aura. However, if you experience any of the following, it's important to seek medical attention:
- Sudden onset of fortification spectra
- Fortification spectra that last longer than an hour
- Fortification spectra that are accompanied by other neurological symptoms, such as weakness, numbness, or difficulty speaking
What Can I Do if I Experience Fortification Spectra?
If you experience fortification spectra, it's important to:
- Rest in a dark, quiet room
- Avoid bright lights and loud noises
- Take over-the-counter pain relievers, such as ibuprofen or acetaminophen
If your symptoms are severe or persist, consult with your doctor. They can help you determine the underlying cause of your migraine and recommend appropriate treatment options.
