What Are The Types Of Headaches What Type Of Headache Is A Migraine

What Happens In Your Body During Migraine | WebMD

There are over 150 types of headaches, divided into two categories: primary headaches and secondary headaches. A migraine is a primary headache, meaning that it isnt caused by a different medical condition. Primary headache disorders are clinical diagnoses, meaning theres no blood test or imaging study to diagnose it. A secondary headache is a symptom of another health issue.

Can Poor Eyesight Trigger Migraines

Poor eyesight is not commonly a trigger for migraine. Although it can cause eyestrain and headaches in some people. Poor eyesight isnt even in the top 10 most common causes of headaches!

Refractive errors, like astigmatism, myopia, hyperopia or presbyopia when uncorrected or under corrected can cause muscle tension. If you squint to see better, you are tensing the muscles in your forehead and around your eyes. Or you may find you lean closer to your computer screen, or lift your chin to try and see through the bottom of your spectacles. These changes to posture and muscle tension around the head, neck and shoulders is a very common cause of headaches. So, having up to date and properly fitting spectacles can actually reduce your muscle tension.

Despite this, when looking for the underlying cause of your headaches or migraines, having a full and thorough eye examination is still high on the list of priorities. Refractive errors may not be a common cause of headache or migraine, but they can contribute to the frequency and intensity of the head pain. There are also other eye related conditions that can cause visual disturbances or headaches such as Angle Closure Glaucoma and Age Related Macular Degeneration.

What about in children?

If you experience migraine headaches, we recommend consulting your doctor and/or eye care professional. They can help you get to the cause and come up with a treatment plan.

When To Get Medical Advice

If your eyesight suddenly deteriorates, make an emergency appointment to see an optician trained to recognise eye abnormalities and signs of eye disease , your GP, or contact GP out of hours service.

It’s important to see an optometrist or doctor urgently if your eyesight suddenly gets worse, particularly if it occurs for the first time.

There are other more serious causes of sight loss that doctors will want to rule out.

Whats Really Happening Inside Your Head

Medical professionals, including Andrew Charles, professor of neurology and director of the UCLA Goldberg Migraine Program, are quick to point out that this type of a migraine is often misunderstood. Internet research and some in the medical field often refer to the condition as an ocular migraine, but Charles said that term is incorrect.

The term ocular migraine is bit of a misnomer because it implies that the problem is in the eye, Charles said. In fact, what causes this is waves of abnormal activity that travel across the surface of the brain in the part of the brain that controls vision. Even though often interpreted by patients and physicians as something happening it in the eye, it is something that is happening in the brain.

These waves of activity that disrupt ones vision can vary in their appearance depending on the person, said Kevin Weber, an assistant professor of neurology in the headache division of the Ohio State University Wexner Medical Center. The auras can appear as a spot in the middle of your vision field, sparking or flashing lights, black or white dots, zigzag or squiggly lines, and in some cases, items may appear disproportionate in size. Those who experience these types of migraines generally notice a change in vision that precedes the onset of a headache.

I had to pull over until I could see again. It was really frightening.

What To Do If You Have A Visual Disturbance

TIL of Silent Migraines, which are migrains that have no ...

If you are suffering from visual disturbances

  • Stop what you are doing. If you are driving, pull over as soon as you can do so safely.
  • Stay calm. Most visual disturbances will pass in 10-30 minutes and are not likely to be a medical issue.
  • Rest, often a cool dark room is most comforting.
  • Take paracetamol, ibuprofen, diclofenac or naproxen whichever painkiller you have previously used comfortably and safely.
  • Record, write down what you feel and see. Take special note of whether or not the disturbance is affecting one or both eyes.

Then, when you get a chance, contact your Optometrist or GP to discuss how soon you should be checked. In most cases these symptoms are not urgent.

But if you have sudden loss of sight in one or both eyes, or in a section of your vision, seek medical advice immediately.

    Why Does A Migraine Affect Vision

    While the exact causes of migraine and aura are not fully understood, we are aware of what happens to the brain after a migraine is triggered. The cortical spreading depression or over-stimulation of the brain has a flow on effect.

    This sudden intense activity in the brain cells is like if all the lights in a city were turned on at once. Then it is followed by a drop-off of activity in that area of the brain. Like a power cut, a blackout in one suburb of the city. The decrease in activity spreads across the top layer of the brain . Like a power outage that gradually spreads from suburb to suburb, until the whole city is in a black out. The drop off starts in the visual areas of the brain , then travels to the body sensation part of the brain , then to the areas important in processing sound .

    If there is a loss of activity in the visual areas of the brain, our eyes will still gather information important for sight, but our brain confuses the information and what we see will be distorted, disrupted and weird! When trying to get a grasp on ideas like this, it helps to remind ourselves that the eyes do not see. The eyes gather visual information about the outside world. This is then packaged into electrical and chemical messages that get sent along nerves to the occipital lobe in the brain. This information is then processed into something our brain can understand like a beautiful sunset or a busy city street.

    Your doctor will try to identify and treat any underlying causes. For example, they may order a blood test to determine the amount of thyroid hormone in your blood if they suspect hypothyroidism is causing your symptoms. They can also prescribe medications to enhance your hormone levels if theyre low.

    If a prescribed medication is contributing to your headache and loss of appetite, talk to your doctor. Dont stop taking your medication until you discuss it with your doctor. They may prescribe other medications known to enhance appetite, especially if youre undergoing cancer treatments.

    What Causes Migraine Pain

    Research is still ongoing, but migraines are thought to likely be caused by a phenomenon called cortical spreading depression . This is a process that happens in the brain, more specifically the cortex, when these brain cells are over stimulated.

    This stimulation affects the production of serotonin and other brain chemicals. Serotonin then stimulates the trigeminovascular system. This system controls the brains blood vessels, causing them to swell.

    Swollen blood vessels do two things:

    • Push on neighbouring nerves causing the sensation of pain.
    • Force the blood to travel through much smaller than normal spaces, making the pulsation of the blood more prominent.

    With changes like this happening to the vessels inside our heads, it isnt all that surprising that people often describe the pain as throbbing or as a feeling of pressure inside their head.

    Symptoms Of Visual Disturbances From Migraine

    Positive symptoms include zig-zag lines which often shimmer and may move across the field of vision, sparkles, dots, stars, spots, squiggles, and flash bulb effects. The classic migraine visual aura consists of an area that is not well seen, surrounded by shimmering zig-zag lines, that gradually enlarges and then breaks up over a period of 15-30 minutes.

    Negative symptoms are blind spots, tunnel vision, complete loss of vision, or loss of all vision to the left or right side.

    Distorted or altered visual symptoms are the sensations of looking through water, heat waves, blurred vision, fractured vision , loss of color vision, objects appearing too large or small, or objects seeming closer or farther than they really are.

    Given the wide variety of visual symptoms that accompany migraine, it is sometimes hard to determine whether ones symptoms are indeed migraine-related, or due to a more serious problem that warrants medical attention. Causes for concern include:

    What Are The Causes

    The exact causes of ocular migraines are not definitively established. However, many scientists think that the symptoms that you experience happen because of reduced blood flow to the brain. Spasm in the blood vessels is what causes a reduction in blood flow.

    The source of visual disturbances in ocular migraines is the retinal blood vessels. Contrarily, the source of migraines with aura is the occipital cortex, which is located at the base of the skull.

    Since the source of the problem in aura migraines is not the eyes but the brain, you will still experience the sensory disturbances even when you close your eyes.

    Tracking Your Migraine Symptoms

    Headaches and Your Vision

    Keeping a record of your migraine symptoms may help you figure out patterns and triggers to your attacks. It may be helpful to record such things as:

    • When and where your pain or symptoms start
    • Whether the pain spreads to your entire head or neck
    • How well and how quickly acute treatment helps reduce the pain or other symptoms
    • How long your pain or symptoms last
    • Whether you experience other symptoms such as vision changes, nausea, or light sensitivity

    What Do Visual Disturbances Look Like

    • Black spots, threads, wiggly lines that float across your vision. We call these floaters. This visual disturbance can occur with or without flashes of light.
    • Patches of shimmering light or flashing lights.
    • Psychedelic colours, distorted colours and shapes, or kaleidoscope vision.
    • Zig-zag patterns or dark spots in your vision.

    These are all associated with visual aura of migraine.

    What Is A Migraine

    A migraine is a recurrent and severe headache which a whopping one in ten New Zealanders suffer from. There are a few different types of migraines which people usually experience:

  • A classic migraine occurs in about 40% of migraine sufferers and has an aura .
  • A common migraine occurs in about 60% of migraine sufferers and has no aura.
  • A silent migraine is when a person experiences the aura, but no headache or pain afterwards.
  • A visual migraine is a silent migraine when the aura is visual.
  • A retinal migraine is very rare and its visual symptoms are the partial or total loss of vision, temporarily in one eye. In recurrent cases, it is most likely to affect the same eye each time. The vision fades out over five minutes, and can be described as a dimming of vision, flashes of light or patches of blank spots that enlarge to block out all sight in that eye. The vision returns to normal within an hour. This loss of vision is caused by reduced blood flow or spasms of the blood vessels in the retina or behind the eye, not in the brain.
  • Migraines might occur rarely, once or twice a year, or they could strike several times a month. The frequency differs drastically between sufferers and is often associated with an underlying cause. Migraines usually run in families as they have a genetic component. People with two parents who suffer from migraines have a 75% chance of having migraines themselves. Women are also three times more likely than men to get them.

    Q What Are The Causes Of Blindness In Children And Infants

  • There are various causes of blindness and visual impairment in infants. Amblyopia, cataracts, congenital glaucoma, and strabismus are some of the problems that can cause blindness in infants. There are certain infections such as pink eye that can cause blindness in infants. Blocked tear ducts often cause blindness in children. Ptosis is another popular cause of blindness in children. Children whose visual system is developed slowly are more prone to blindness. Premature babies whose blood vessels arent completely developed yet can suffer from blindness due to ROP or retinopathy of prematurity.
  • What Is An Ocular Migraine

    How do You Know Your Glasses Prescription is Wrong?

    An ocular migraine is a rare condition characterized by temporary vision loss or even temporary blindness in one eye. Ocular migraines are caused by reduced blood flow or spasms of blood vessels in the retina or behind the eye.

    In an ocular migraine, vision in the affected eye generally returns to normal within an hour. Ocular migraines can be painless or they can occur along with a migraine headache. Ocular migraines are also called retinal migraines.

    Unfortunately, “ocular migraine” often is used to describe a much more common condition called a visual migraine or migraine aura.

    Visual migraines also cause temporary vision disturbances. But the vision problems caused by visual migraines affect both eyes, not just one eye, and tend to be somewhat shorter usually around 20 minutes in duration.

    Now, lets take a closer look at ocular migraines and visual migraines .
