Have you ever been out and about, or just sitting at home, and suddenly your eyes started to see colorful lights and patterns? Did it go away after a while? You might have been a little worried. If so, you might be experiencing a condition called a "silent migraine." In this case, you may not have a severe headache, but you may still experience some of the other symptoms of a migraine. Although it can be a scary experience, if you are aware of it, it is not a big deal to manage. So, let's talk about this in detail.
What is Silent Migraine?
Simply put, a silent migraine is a migraine that occurs without a headache. However, you may experience other symptoms that are common with migraines, especially sensory changes called "auras." "Auras" are unusual changes in your senses, such as vision, hearing, and touch. Imagine, it's like magic.
Some people call this "migraine without a headache," "typical aura without headache," or "acephalgic migraine." Although there are many names, they all mean the same thing. It is said that about 5% of people with migraines may experience this silent migraine. So, even if you don't have a headache, this can still interfere with your daily activities and life. That's why it is very important to be aware of this.
What are the symptoms of silent migraine?
Symptoms of silent migraines usually appear within a few minutes and can last for up to an hour. The most common symptom is vision changes. Let's take a look at what these symptoms are.
Changes in vision come first.
During a silent migraine, you may notice a variety of things. For example:
- Bright lights: You may suddenly see bright lights that make your eyes appear blue, like when you are hit by a flashlight.
- Wavy or jagged lines: It can look like looking at a wave of water, or it can look like jagged, broken lines. Some say it looks like the walls of a castle.
- Flashing dots or sparkles: You may see small dots moving here and there, or things that sparkle like sparks or stars.
These visual disturbances usually start in the middle of your vision and seem to spread to the sides. Sometimes, you may also experience areas of your vision that are dark and not visible (scotomas) , which look like a small black spot in your field of vision.
Could there be other symptoms?
Yes, in addition to changes in vision, there may be several other symptoms:
- Numbness or tingling (Paresthesia): This is a tingling sensation, or a crawling sensation, in an arm, leg, or face. This numbness may start in one hand, move up the arm, and spread to the face, lips, or tongue.
- Difficulty speaking (Aphasia): You may feel like you're slurring your words, stuttering, or having trouble getting your words out. Some may even think they're talking like they're drunk.
- Tinnitus: You may hear a constant "ringing" sound in your ears , or a buzzing sound like bees.
- Dizziness: You may feel dizzy or lightheaded. You may also feel like things are spinning around you.
Important: Some of these symptoms, such as difficulty speaking, numbness, and weakness, can be similar to symptoms of more serious conditions, such as stroke . Therefore, if you suddenly experience these severe symptoms, it is very important to seek medical advice immediately. Don't think twice about it.
Are there warning signs before a silent migraine occurs?
Sometimes a silent migraine can come on suddenly, without any warning. However, for some people, like a migraine that comes with a headache, it can have several phases . Warning signs appear in an initial phase called the "prodrome." This phase can begin about 24 hours before the aura. Symptoms that may occur during the "prodrome" phase include:
- Feeling irritable: Getting angry even when you're alone, and getting upset over small things.
- Feeling depressed: You may feel sad and frustrated.
- Fatigue: Feeling exhausted no matter how much sleep you get.
- Yawning: Just yawning frequently.
- Peeing more than usual: Needing to go to the toilet more often.
- Trouble sleeping: Not being able to fall asleep, or waking up frequently.
- Craving specific food: Craving specific foods .
- Nausea: Feeling like you're going to vomit.
- Increased sensitivity to lights or sound: Even a small amount of light or sound is difficult to tolerate.
- Difficulty concentrating, reading or speaking: Unable to concentrate on anything, unable to read a book.
- Neck pain or stiffness: The neck feels stiff and unable to lift.
- Hyperactivity: Can't sit still, just fidgeting.
The "aura" is the second phase of a migraine. After that comes the "postdrome." Not everyone with silent migraines experiences this. But the "postdrome" phase is like a "migraine hangover." That is, even after the migraine is over, you feel upset and tired, like you've had too much to drink.
What causes silent migraines?
The exact cause of this is still being investigated. But researchers say that the "aura" that comes with migraines is related to a brain process called "cortical spreading depression" (CSD) . Simply put, this is when cells on the surface of the brain (cerebral cortex) suddenly become hyperactive, and then become inactive for a while. This process spreads throughout the brain like a wave. Think of it like ripples spreading when you drop a stone in water. Some genetic mutations have also been found to affect this condition.
Additionally, certain triggers are known to increase the risk of developing silent migraines. Like regular migraines, silent migraines can also be affected by these triggers:
- Emotional stress: Often, things like stress, anger, and sadness that accumulate without us realizing it can affect us. This can sometimes come when we are unable to resolve a major problem.
- Hormonal changes: This condition can be seen especially in women during their menstrual cycle, during pregnancy, or during menopause.
- Changes to your sleep: Not getting enough sleep, staying up late, or sleeping too much can also affect your sleep. Changing your sleep pattern is also not good.
- Weather condition changes: Some people experience this when the weather suddenly changes, such as when the temperature or air pressure changes.
- Exposure to bright lights, loud sounds or strong odors: A sudden bright light, a loud noise, or strong odors such as some perfumes or smoke can cause this.
Can silent migraines cause complications?
Research has shown that people with silent migraines are at a slightly higher risk of a condition called a "transient ischemic attack" (TIA) . A "transient ischemic attack" (TIA) is simply a "mini-stroke." In this, the blood supply to the brain is temporarily interrupted. So it's good to be aware of this as well.
How to recognize silent migraine?
A doctor will diagnose silent migraine by listening to your symptoms and performing a physical exam. They may also perform neurological examinations to rule out other conditions that could be causing your symptoms. Your doctor may ask you questions such as:
- Describe what you saw during the experience. You may also be asked to draw a picture of what you remember seeing.
- When did the symptoms start and how long have they been present?
- How often do you experience these specific symptoms?
Your answers to these questions will help the doctor determine whether this is a silent migraine or something else.
What are the treatments for silent migraines?
The best way to treat silent migraines is to identify your triggers. Your doctor may ask you to keep a diary of what you did and experienced before the warning signs of a silent migraine appeared. For example:
- What did you eat?
- What were you doing at that time?
- Did you feel stressed?
When you note things like this, you'll understand what causes this.
Trying to manage a silent migraine during the prodrome phase can help reduce the duration of the aura and other symptoms. For example, taking pain medication at the first sign of an aura can help reduce nausea, sensitivity to light, and sound. Researchers are also investigating different medications that may prevent silent migraines.
What can you expect if you have silent migraines?
There is no cure for silent migraines. However, knowing what triggers them can help you manage your symptoms and keep them from interfering with your daily life. Don't worry, you can learn to live with it.
Can silent migraines be prevented?
There's no way to completely prevent a silent migraine. However, there are a few things you can do to help relieve symptoms during the "prodrome" phase:
- Take a break: Sit in a quiet, dark room and lie down for a while. This will help you avoid environmental triggers like light and noise. Being relaxed and calm will also reduce stress. This can also cause a silent migraine.
- Stay hydrated: During the "prodrome" stage, you may urinate frequently, so stay hydrated. Try to drink at least 8 glasses of water a day.
- Don't skip meals: If you're feeling nauseous, try to eat smaller meals rather than large meals. But stay away from foods that trigger migraines.
- Manage neck pain: If you have neck pain or stiffness, apply a heating pad . Or you can wrap a hot water bottle in a cloth.
When should I see my doctor?
See your doctor if:
- If you have frequent silent migraines.
- If your symptoms worsen. This includes the symptoms of the "prodrome" phase, as well as the "aura" experienced during a silent migraine.
When should I go to the Emergency Department (ETU) ?
We've already mentioned that some silent migraine symptoms can be similar to those of a stroke . So, if you experience symptoms like difficulty speaking, numbness, or weakness that are more severe than you would normally experience with a silent migraine, go to the emergency room at your nearest hospital right away. Don't put it off, because it could be life-saving.
Imagine this: You're driving, and suddenly you see a bright light or something like that on the road ahead. You blink, but it's still there. You pull over, and your vision returns to normal after a while. If this has ever happened to you, you're probably experiencing a silent migraine.
Silent migraines are migraines that don't cause a headache. They're not life-threatening, but they can be a little scary and can interfere with your daily activities. If you're experiencing these vision changes, or any of the other symptoms we've discussed, be sure to talk to your doctor. He or she can recommend ways to reduce your silent migraine symptoms and reduce the impact they have on your life.
