There's some relief, however slight, available for migraine sufferers -- a recent study has shown experiencing migraine headaches does not affect cognitive health in the long term.

In the most recent issue of the British Medical Journal, a study out of Brigham and Women's Hospital found no evidence of faster cognitive decline among women who suffered from migraines versus those who did not.

The findings, which were based on a study following more than 6,300 women, will come as a relief to those who experience the debilitating headaches. In 2007, one study found a correlation between migraines and "tiny transient strokes," a finding that could mean oxygen and blood stopped flowing to the brain for periods of time, killing brain cells and leaving long-term effects.

Confusing the matter is where migraines come from -- while there is no one cause, it's possible brain chemicals could be behind the pain, according to the Mayo Clinic.

Other studies have even found those who experience migraines have better memories as they age, Time magazine reported, possibly thanks to habits formed to combat the ailment. So the news out of Brigham and Women's hospital is undoubtedly welcomed by the approximately 17 per cent of the population for whom migraines recur.

"This is an important finding for both physicians and patients. Patients with migraine and their treating doctors should be reassured that migraine may not have long-term consequences on cognitive function," said Pamela Rist, a research fellow in the Division of Preventive Medicine at BWH, and the study's lead author.

14 types of headaches, their causes and how to make them go away:

  • Rebound Headaches

    Much like overuse of nasal decongestants can lead to a perpetually stuffy nose, rebound headaches are chronic headaches caused by medication overuse. <br><br> How often is too often? Regularly taking any pain reliever like acetaminophen (Tylenol), aspirin or ibuprofen (Advil, Motrin) more than twice a week, or taking triptans (migraine drugs) for more than 10 days a month, can put you at risk for rebound headaches in just a few months. <br><br> Don't try to treat these on your own. A doctor can help you stop the culprit drug, using alternatives until it's out of your system. <br><br> <strong>More from Health.com:</strong><br> <a href="http://www.health.com/health/gallery/0,,20537878,00.html" target="_hplink">18 Signs You're Having a Migraine</a><br> <a href="http://www.health.com/health/gallery/0,,20567687,00.html" target="_hplink">Headache-Proof Your Home</a><br> <a href="http://www.health.com/health/gallery/0,,20306955,00.html" target="_hplink">The Top Migraine Triggers</a> <br><br> <em>Flickr photo by <a href="http://www.flickr.com/photos/kickthebeat/5366862660/" target="_hplink">kickthebeat</a></em>

  • Tension Headaches

    This is the most common type of headache, which usually feels like a constant aching or pressure -- rather than throbbing -- on both sides of the head or at the back of the head and neck. <br><br> Triggers can include stress, anxiety, bad posture and clenching your jaw, and these headaches can become chronic, although they usually aren't severe. Experts aren't sure of exact cause, although it may be due to altered brain chemicals or mixed signals in the nerves leading to the brain. <br><br> These usually respond to over-the-counter pain relievers, such as aspirin, ibuprofen or acetaminophen. Stress-relief may help.

  • Dental Headaches

    There are dental-related conditions that can trigger headaches or face pain, such as bruxism and temporomandibular joint disorder (TMJ). <br><br> Bruxism is grinding your teeth at night, while TMJ affects the joints, located just in front of your ear, which connect the jaw to the skull. <br><br> TMJ can be caused by bad jaw alignment, stress, poor posture (like sitting at a computer all day) or arthritis, which affect the cartilage, muscles or ligaments in the jaw. <br><br> Your dentist can help diagnose these types of headaches, and treatment includes stretching the jaw, hot or cold packs, stress reduction and bite guards. <br><br> <em>Flickr photo by <a href="http://www.flickr.com/photos/usarmyafrica/5725063775/" target="_hplink">US Army Africa</a></em>

  • Cluster Headaches

    These one-sided headaches are short-lived (15 minutes to 3 hours), but excruciating. These are so painful they're sometimes called the suicide headache. <br><br> Cluster headaches recur regularly, even multiple times daily, over a certain period of time and then may be followed by a headache-free period of months or even years. There may be redness and tearing in one or both eyes. More common in men than women, cluster headaches can be treated with triptans or oxygen (OTC painkillers may not help). Triggers can include alcohol, cigarettes, high altitudes and certain foods.

  • Migraines

    Migraines are severe headaches that are three times as common in women as men. The cause isn't clear, but genes do play a role, and brain cell activity may affect blood vessel and nerve cell function. <br><br> One common migraine trigger is change, including hormones, stress and sleeping or eating patterns. <br><br> "If you know skipping meals is a trigger, don't skip meals while menstruating and having a late night," says Peter Goadsby, M.D., director of the Headache Center at the University of California, San Francisco. Treatment can include acetaminophen, ibuprofen or triptans (such as Imitrex or Zomig), which are drugs that help treat or prevent migraines. <br><br> <em>Flickr photo by <a href="http://www.flickr.com/photos/sashawolff/3108464695/" target="_hplink">SashaW</a></em>

  • Caffeine Headaches

    You love your coffee, but it can be a cruel companion. For example, if you have two cups of coffee every day at 9 a.m., and then miss those cups when you oversleep on Saturday -- boom! -- you can end up with a caffeine withdrawal headache. <br><br> You will be more likely to have them, though, if you drink a lot (say, five cups of coffee a day), then go cold turkey. <br><br> You have two options, Goadsby says, "You can take caffeine when you normally do and feed the addiction, or quit altogether." <br><br> <em>Flickr photo by <a href="http://www.flickr.com/photos/qmnonic/5602335734/" target="_hplink">qmnonic</a></em>

  • Orgasm Headaches

    Orgasm-induced headaches are caused by, well, having an orgasm. <br><br> These are relatively rare and are more common in younger people, particularly men, Flippen says. They usually start shortly after intercourse begins and end in a "thunderclap" headache at climax. <br><br> A dull headache can often linger for hours or a day. Flippen says that there is often no known cause for these headaches and they usually go away on their own. He does recommend seeing a doctor, however; in rare cases they can be a sign of something more serious. A dose of pain reliever before sex may help ease the pain.

  • Early Morning Headaches

    If you're waking up in pain, there are several possible culprits. Migraines are more likely to happen in the morning, or medication may be waning in your body as you sleep, which causes a rebound headache, Goadsby says. <br><br> Sleep apnea sufferers may also be more prone to headaches early in the day, as are those with dental headaches. <br><br> Finally -- and this one is the least likely, so relax all of you hypochondriacs out there -- it could be a symptom of a brain tumor, Goadsby says. <br><br> <em>Flickr photo by <a href="http://www.flickr.com/photos/pyxopotamus/2575024540/" target="_hplink">me and the sysop</a></em>

  • Sinus Headaches

    These types of headaches win the gold medal for overdiagnosis, according to Goadsby. <br><br> People with migraines often mistake them for sinus headaches. (One study found that 88 percent of people with a history of sinus headaches probably had migraines instead.) Symptoms like sinus pressure, nasal congestion and watery eyes can happen in both types. <br><br> A true sinus headache is related to an infection and comes with nasal discharge that is green or tinged with red, says Goadsby. Sinus infections often resolve with time or antibiotics, if necessary, and shouldn't cause nausea or light sensitivity, which are migraine symptoms. <br><br> <em>Flickr photo by <a href="http://www.flickr.com/photos/tanj/238445815/" target="_hplink">tanjila</a></em>

  • Ice Cream Headaches

    Brain freeze! Most people have experienced the shooting head pain that can occur while enjoying a icy cold drink or treat on a hot day. People with migraines may be especially prone to them. <br><br> They have an impressive medical name -- sphenopalatine ganglioneuralgia -- but they're not all that serious. Experts think a cold sensation on the roof of the mouth can cause an increase in blood flow to one of the brain's arteries. <br><br> The cure? Take a momentary break from the frosty goodness until the pain subsides, or sip warm water to help constrict the brain artery. <br><br> <strong>More from Health.com:</strong><br> <a href="http://www.health.com/health/gallery/0,,20537878,00.html" target="_hplink">18 Signs You're Having a Migraine</a><br> <a href="http://www.health.com/health/gallery/0,,20567687,00.html" target="_hplink">Headache-Proof Your Home</a><br> <a href="http://www.health.com/health/gallery/0,,20306955,00.html" target="_hplink">The Top Migraine Triggers</a> <br><br> <em>Flickr photo by <a href="http://www.flickr.com/photos/stevendepolo/3796415185/" target="_hplink">stevendepolo</a></em>

  • Chronic Daily Headaches

    If you have a headache at least 15 days per month for more than three months you're considered to have chronic daily headaches, says Goadsby. <br><br> These could be caused by overuse of pain medications (ie, rebound headaches), head injury or, in rare cases, meningitis or tumors. <br><br> If there is no obvious cause, it could be because your body's pain signals are heightened or not working properly. <br><br> These headaches may respond to antidepressants; beta blockers like atenolol, metoprolol or propanolol (used to treat high blood pressure and migraines); anti-seizure medications like gabapentin or topiramate; pain relievers like naproxen (Aleve); and even Botox injections.

  • Menstrual Headaches

    As if PMS wasn't bad enough, the sudden drop in estrogen right before your period can sometimes trigger migraines, Flippen says. <br><br> These usually occur between three days before and two days after your period has started. Other women may have PMS-related headaches that aren't migraines. <br><br> These arrive about six days or so before your period, at the same time as any moodiness, cramping or other PMS symptoms. Flippen recommends over-the-counter headache remedies; magnesium supplements may also help PMS-related head pain.

  • Weekend Headaches

    Some people may experience headaches that mainly show up on the weekend. These are thought to be caused by oversleeping on weekend mornings, going to bed later at night or caffeine withdrawal. <br><br> Also, if your stress level is high all week, the weekend release may trigger a headache. <br><br> Over-the-counter pain medications can be helpful, as can sticking to your regular sleep-wake schedule. <br><br> <em>Flickr photo by <a href="http://www.flickr.com/photos/barkbud/4132495426/" target="_hplink">bark</a></em>

  • Emergency Headaches

    Most headaches aren't an emergency, but there are a few symptoms that warrant rapid attention, says Flippen. One is a sudden onset headache that is quickly "explosive." Another is when a headache comes with a fever or extreme rise in blood pressure, or if it occurs after a blow to the head or exertion. <br><br> Other problematic symptoms include vision or speech change, neck stiffness, dizziness, loss of sensation or muscle weakness on one side of the body. Call 911 if you have these worrisome symptoms in addition to headache. <br><br> <strong>More from Health.com:</strong><br> <a href="http://www.health.com/health/gallery/0,,20537878,00.html" target="_hplink">18 Signs You're Having a Migraine</a><br> <a href="http://www.health.com/health/gallery/0,,20567687,00.html" target="_hplink">Headache-Proof Your Home</a><br> <a href="http://www.health.com/health/gallery/0,,20306955,00.html" target="_hplink">The Top Migraine Triggers</a> <br><br> <em>Flickr photo by <a href="http://www.flickr.com/photos/paulbeattie/3328164623/" target="_hplink">Paul Beattie</a></em>
