How To Tell If Youre Experiencing A Migraine Or A Stroke

How Long Does A Migraine Last 2021 01 28 14 11 56

If you routinely experience migraines with or without aura, its paramount to understand the signs and symptoms of a potential stroke. As previously mentioned, many symptoms are identical across migraines, strokes, andtransient ischemic attacks . These shared symptoms include, but are not limited to, visual changes and disturbances, muscle fatigue, and impaired speech.

Before we dive into;the key differences between migraines and strokes, lets first define positive and negative symptoms. Apositive symptom;is the addition of a symptom, as a result of excess electrical discharges in your central nervous system . Positive symptoms include visual disturbances such as flashing lights, and motor disturbances such as muscle spasms. Conversely, negative symptoms are caused by a loss of CNS function and manifest as a negation of normal functionality. Typical negative symptoms include tunnel vision, hearing loss, and loss of motor control or numbness.

This distinction is important to functionally understand, because strokes normally produce negative symptoms, whereas migraines with aura normally produce positive symptoms. For example, common stroke side effects include numbness in the face or along one side of the body, trouble speaking, loss of balance, andblurred vision,according to the CDC. A migraine with aura, on the other hand, may cause the migraineur to see flashes of light, a visual zigzagging pattern, blinking lights, and dots.

What To Know About Migraine With Aura

Doctors and patients alike have been fascinated and puzzled by how migraine and aura go hand in hand. In fact, when diagnosing an individual with migraine, people may fall into the category of migraine with aura or migraine without aura, or both. Often described as a warning sign, the aura stage of migraine is unique because it is only experienced by 25 to 30% of people with migraine.

Ocular Migraines And Stroke

Henry HoffmanThursday, September 27th, 2018

Today, migraines are considered the most common neurological disorder according to the Journal of Stroke,;and, in the United States alone, about30 million;people suffer from these debilitating headaches. Research has determined that all migraineurs are at a higher risk of suffering a stroke, and this risk factor is potentiallydoubled or tripled;for individuals who suffer from migraines with visual disturbances collectively known as aura.

Unfortunately, migraines with aura exhibit similar symptoms to those associated with certain life-threatening conditions, namelytransient ischemic attacks;and strokes. For this reason, many migraineurs may mistake early stroke warning signs for classic migraine symptoms. Telling the difference and recognizing a medical emergency for what it is can be difficult, but isnt impossible.

    How Do You Treat Visual Disturbance

    Firstly, do not panic; visual disturbances can be frightening, but in most cases are short lived. If you are driving or operating machinery, stop what you are doing and wait for the symptoms to go away. Make a note of your symptoms, how long they lasted and what you were doing just before they began. In most cases, there is a common trigger and keeping a diary of symptoms can help work out what the trigger is. Simply avoiding the trigger, where possible, may be all you need to do.

    Common triggers include:

    What Causes A Migraine

    Can Migraines last for a week ? | Health and Life

    Although migraines are extremely common, their exact cause remains unknown. It appears likely that the visual aura relates to a phenomenon called cortical spreading depression which temporarily affects electrical impulses in the brain. The pain of a migraine headache probably relates to spasm or irritability of blood vessels in the brain, which are sensitive to pain . Beyond these hypotheses, however, the exact mechanism that triggers a migraine remains unknown.

    It is often possible to identify certain risk factors that increase the chance of having migraines. A positive family history is very common, so the doctor will often ask about headaches in ones parents or siblings. Overall, migraines are more common in women than in men. In addition, a persons hormonal status can affect the pattern of migraines they experience; therefore, it is natural for a woman to notice a change in headaches and other migraine symptoms in adolescence or around the time of menopause.

    Many individuals can identify specific triggers for their migraines. These triggers include fatigue, skipping a meal, caffeine withdrawal, stress, and certain foods . For many patients with isolated visual migraines, however, the events can be very infrequent and no definite trigger can be determined.

    Treatment Options For Migraine

    Once youve been diagnosed, there are no special therapies to treat migraine-related visual disturbances, outside of your regular migraine treatments. Since the vision problems usually dont last very long, patients often choose not to treat them specifically. By keeping a record of your migraine attacks and triggers you can learn to recognize when a headache is likely to follow visual problems, and use the onset of these as an advance warning. That could give you the opportunity to take over-the-counter painkillers or migraine medication before the pain strikes, hopefully reducing its intensity.

    If you experience visual disturbances regularly that are not accompanied by a headache, see an ophthalmologist and your primary care doctor to rule out optical or other medical conditions that could be serious.

    What Are The Acute Treatments For Migraine

    An isolated visual migraine, without headache, typically does not require any acute treatment, since the visual symptoms resolve on their own fairly quickly. The first few times someone experiences a visual migraine it usually causes a lot of anxiety. Once someone has become familiar with the symptoms of a visual migraine, new episodes no longer cause the same level of anxiety.

    It can be helpful to try to rest during the episode. Some patients benefit from other strategies, including eating something, having caffeine, or taking an over-the-counter medication such as acetaminophen or ibuprofen .

    Patients in whom the visual symptoms are accompanied by a severe headache often benefit from additional therapies. The goal of these medications is to try to cut short the headache before it becomes too severe. Some patients find naproxen , which is a stronger anti-inflammatory medication, to be helpful. Other patients try a class of medications known as triptans.

    Triptans are specially designed to work on receptors on blood vessels and brain cells in order to halt a migraine at an early stage. Although there are a number of different triptans, made by several different pharmaceutical companies, each of these is approximately equally effective. Triptans are often taken orally, but also come as injections and nasal sprays. These medicines are generally not considered safe in patients with a history of strokes, heart attacks, or other vascular diseases.

    Summary Of Retinal Migraines

    Retinal migraines are a subtype of migraine associated with monocular vision symptoms. Patients suspected of having retinal migraine should be carefully assessed by their doctor for an underlying cause. To help distinguish retinal migraine from migraine with typical aura, it is important that people carefully assess whether there vision symptoms are perceived in one or both eyes by alternating looking through either eye. The distinction between retinal migraine and migraine with typical aura has ramifications for treatment choices as well as prognosis counselling.

    Ocular migraine symptoms;generally include a small blind spot that affects your central vision in one eye. This blind spot gets larger, making it impossible for you to drive safely or read with the affected eye.

    In some cases, the entire visual field of one eye may be affected. Generally, the episode lasts less than an hour.

    Visual migraine symptoms;can vary, and may include:

    Visual migraines often appear suddenly and may create the sensation of looking through a cracked window. The visual migraine aura usually moves across your field of view and disappears within 30 minutes.;

  • A flickering blind spot in the center or near the center of your field of view

  • A wavy or zigzag ring of colored light surrounding a central blind spot

  • A blind spot that slowly migrates across your visual field

  • The symptoms of a visual migraine typically affect both eyes and last less than 30 minutes. A migraine headache may occur shortly after the symptoms of a visual migraine subside or no headache may occur.

    If youre experiencing a blind spot or other visual disturbance and youre not sure if its an ocular migraine or a visual migraine , cover one eye at a time. If the visual disturbance affects just one eye, its probably an ocular migraine. If it affects both eyes, its likely a visual migraine.
