When to see your doctor about headaches



When to see your doctor about headaches


Most of us have experienced a headache at some point in our lives. The occasional headache may be nothing to worry about, but when they are frequent and unmanageable, it may be time to call the doctor.
“It’s extremely common to experience a headache once in a while,” says Dr. Christine Lay, headache specialist and director of the Centre for Headache at Women’s College Hospital.
“However, what’s not normal is to have recurrent, episodic headache that seems to come every week or every month – often with your menstrual cycle – and becomes difficult to manage,” Dr. Lay says. “That’s not something we want people accepting as normal.”
The most common type of headache is a tension-type headache.
“We no longer use the term ‘tension headache’ because it implies the person is tense or under stress or perhaps not managing things as well as they could,” Dr. Lay says. Tension-type headaches are usually fairly mild and manageable, usually with no associated light or sound intolerance or feeling sick, so they generally don’t require a doctor’s attention.
Migraine is the most common headache that brings a sufferer to the doctor for help. However, 50% of sufferers remain undiagnosed or misdiagnosed. In North America, the most common misdiagnosis for migraine is tension-type headache or sinus headache. Many migraine patients have weather-triggered headaches and sometimes they have a runny nose with it, so it gets blamed on sinus headache. You don’t have to have symptoms such as strictly one-sided headaches, vomiting or an aura (a visual or sensory disturbance that may accompany a headache) to be experiencing migraine.
Migraine headaches are usually moderate to severe and make it difficult for people to carry out routine activities. They are usually associated with sensitivity to light or sound, and with nausea, often resulting in a sufferer seeking rest in a dark quiet place.
Dr. Lay identifies several headache scenarios that should prompt a trip to the doctor:
  • a worst-ever headache, or brand new headaches in someone who never had headaches before
  • recurrent headaches
  • headaches that are becoming difficult to manage
  • headaches relieved by over-the-counter medication, but you feel like you’re taking a lot of it
The majority of people seeking help for headaches are those who are having a headache several times a month, they’re taking over-the-counter medicine but not getting the best relief, and the headache is becoming more disabling or starting to interfere with their ability to function, Dr. Lay says.
Your family doctor is a good place to start for headache treatment.
“If you have a family doctor who has understanding of migraine and the appropriate treatments then you’re in good hands,” Dr. Lay says. But if your family doctor is unable to help, you may need to ask for an evaluation with a neurologist or a headache specialist.
You can help both yourself and your doctor by being a well-educated patient. That means you can provide your doctor with the information she may need to treat you:
  • a calendar of your headaches for the last three months
  • medications you’re taking or have tried in the past, and how effective they are
  • any identifiable triggers, such as weather or hormone fluctuations
The calendar you provide should show when you had a headache, how long the headaches last, and when you had your period so you can see whether there’s any association with your menstrual cycle. 
“It’s really looking at how often you’re having a headache and how debilitating that headache is,” Dr. Lay says, adding that studies have shown that at 80 per cent of migraine patients say they can’t function very well when they have a migraine, and 50 per cent say they have a significant degree of disability, leading to decreased work or school productivity.
“Migraine associated disability just keeps getting worse if migraine is undiagnosed or despite a diagnosis it is not effectively treated. It takes over a sufferer’s life.”
Don’t just list your medications: include the dosage you’ve been taking, how often you take it and whether it’s effective.
Finally, Dr. Lay advises patients to make a specific appointment with their doctor to talk about headache – don’t try to make it part of your annual checkup or another appointment.
“Because you really need a dedicated amount of time to talk about it and get a sense of what’s going on in order to develop a plan of management,” she says.

What is the central analgesic mechanism of acupuncture for migraine?

The central analgesic mechanism of acupuncture for migraine remains poorly understood. Acupuncture has been shown to become a recommended treatment for migraine sufferers. However, a single acupuncture stimulus cannot be indicative of the cumulative effects of acupuncture treatment. Prof. Fanrong Liang and colleagues from Chengdu University of Traditional Chinese Medicine recruited migraine sufferers receiving 1 month of acupuncture treatment and explored the central analgesic mechanism of the cumulative effects of acupuncture for migraine. The aim of their study was to examine changes in brain functional activity and central networks in subjects with migraine undergoing acupuncture at Shaoyang uncommon acupoints. This trial has been registered on http://www.clinicaltrial.gov and provides a further explanation of the central analgesic mechanism by which acupuncture at Shaoyang acupoints treats migraine. These findings are published in the Neural Regeneration Research (Vol. 8, No. 28, 2013).

What Not to Do for Migraines




Mary Elizabeth Dallas 

HealthDay - ‎Friday‎, ‎22‎ ‎November‎, ‎2013

Prescription pain medications should not be the first treatment for migraines. And doctors shouldn't routinely order brain scans for patients with these debilitating headaches, according to new guidelines.
Taking a stand on common but often unnecessary or potentially risky tests and treatments for migraine, the American Headache Society published new recommendations in the November-December issue of the journal Headache.
"Our aim is to encourage doctors and patients to think carefully about medical care that can be harmful or unnecessary," said Dr. Elizabeth Loder, president of the American Headache Society. "We didn't approach this with cost uppermost in mind. The goal is to help address the problems of low-value care."

Opioid painkillers, such as OxyContin and Vicodin, and the barbiturate butalbital pose serious long-term risks, the society said.


"The effectiveness of opioids is not the question," explained Loder, chief of the division of headache and pain in the neurology department at Brigham and Women's Hospital in Boston. "The problem is that even if they are effective in a single attack, for many people migraine is a chronic disorder that they will have for many decades."
The risk of dependency associated with these drugs is evidenced by the growing epidemic of prescription painkiller abuse in the United States. Nearly three out of four prescription drug overdoses are caused by opioid painkillers, according to the U.S. Centers for Disease Control and Prevention.
"This ends up being a second problem patients have," Loder noted.
Using too much of these pain medications can also lead to a condition called medication overuse headache, said another expert.
"There is a lot of research that opioids actually increase the sensitivity to pain in the head," said Dr. Rebecca Erwin Wells, assistant professor of neurology at Wake Forest Baptist Medical Center in Winston-Salem, N.C. Medication overuse headaches are difficult to treat, Wells added.
In addition, the guidelines indicate that brain scan studies should not be performed on patients with stable headaches that meet criteria for migraine. And CT scans should not be used in a non-emergency situation as a diagnostic tool for headache patients when MRI is available.
"MRI can diagnose more conditions that may cause headache that CT scans can miss," Loder explained.
Also, unlike CT scans, MRIs use powerful magnets and do not expose patients to radiation. "MRI is better value and safer," Loder concluded.
The headache specialists also said that surgery targeting migraine trigger points is still experimental and not recommended outside of a clinical trial.
"We lack sufficient evidence to say the benefits of surgery outweigh the potential harms or that it is even helpful," Loder cautioned. Before new drugs can be approved for use, they must go through rigorous testing that meets a certain standard, she noted, "and the standard for surgical interventions that are irreversible should not be lower."
Finally, prolonged or frequent use of over-the-counter pain medications for headache is also unwise, the guidelines state. People shouldn't take these drugs more than twice a week, noted Wells.
Loder agreed. "It's not good for the kidneys, liver or stomach to be taking these medications on a daily basis," Loder said. "There are a lot of strategies that can work that are better than just grabbing handfuls of Motrin."

So what does work for most migraine sufferers? Triptans are a family of drugs used to stop migraines once they start, Loder said. And preventive therapies such as biofeedback can be used on a regular basis by people who experience frequent migraines, she added. Biofeedback is a technique that people can learn to use to help change how their body responds to physical symptoms.

Getting enough sleep and not skipping meals can also help keep migraine pain at bay, she suggested.
Migraine treatment and perceptions of the condition itself have changed dramatically over the years. Scientists now believe migraine has a genetic link and that the disorder involves brain chemistry and nerve pathways.
"We understand a lot more about different kinds of headache and have specific treatments that work," Loder said.
It's estimated that 12 percent of Americans get migraine headaches, three times as many women as men.

Migraine-associated brain changes not related to impaired cognition

NIH-funded study tracks nearly 300 people for 9 years

Women with migraines did not appear to experience a decline in cognitive ability over time compared to those who didn't have them, according to a nine-year follow up study funded by the National Institutes of Health.
The study also showed that women with migraine had a higher likelihood of having brain changes that appeared as bright spots on magnetic resonance imaging (MRI), a type of imaging commonly used to evaluate tissues of the body.
"The fact that there is no evidence of cognitive loss among these women is good news," said Linda Porter, Ph.D., pain health science policy advisor in the Office of the Director at the National Institute of Neurological Disorders and Stroke (NINDS), which provided funding for the study. "We've known for a while that women with migraine tend to have these brain changes as seen on MRI. This nine-year study is the first of its kind to provide long-term follow-up looking for associated risk."
"An important message from the study is that there seems no need for more aggressive treatment or prevention of attacks," said Mark C. Kruit, M.D., Ph.D., one of the principal investigators, and a neuroradiologist from Leiden University Medical Center, the Netherlands, which led the study. Dr. Kruit and associates evaluated MRIs for changes in the white matter, brainstem, and cerebellum that appeared on the scans as bright spots known as hyperintensities. Previous studies have shown an association between such hyperintensities and risk factors for atherosclerotic disease, increased risk of stroke and cognitive decline.
The extent of MRI brain findings increased slightly with time, according to the population-based study that tracked 286 men and women with and without migraines.
Men with migraines had no greater incidence of such changes compared with age-and sex-matched controls. Although female participants with migraine in this study were more likely to have hyperintensities, there was no clear relation to the frequency of migraine attacks, the type of migraine or how they were treated.
Standardized measures of cognitive abilities such as memory, concentration, and attention did not show significant losses among people with migraine-associated lesions compared to those without migraine. The brain changes that give rise to the bright spots seen on MRI are unknown. More research is needed to find out if these are related to ischemia and ischemic stroke risk, according to the researchers.

The findings, which appear in the Nov. 14th issue of the Journal of the American Medical Association, update observations from an investigation conducted in 2000 showing that women with migraines were more likely than age-matched controls to have scattered areas of white matter changes on MRI scans. That initial population-based study, known as the Cerebral Abnormalities in Migraine, an Epidemiological Risk Analysis (CAMERA-1), screened and evaluated 295 men and women with migraine and compared them with 140 age- and sex-matched controls. In that study, people who had more frequent migraines also had a higher incidence of changes seen on their MRIs, suggesting that migraine attacks could have a cumulative effect.
In the current investigation, known as CAMERA-2, researchers sought to tease out differences between men and women, and to find out whether the type of migraine was associated with an increase in the volume of new white matter changes relative to that seen in the initial study. Researchers reassessed 286 of the original participants. Among them, 114 had migraine with aura, 89 had migraine without aura, and 83 were controls.

Compared with baseline, women with migraines were twice as likely as those without such attacks to have an increase in the volume of diffuse white matter changes. However, this increase was still very small, said one of the study's investigators, Lenore J. Launer, Ph.D., chief of the Neuroepidemiology Section at the National Institute on Aging (NIA).

CAMERA-2 also showed no correlation between new brain lesions and migraine frequency. This finding may be due to the fact that structural changes to the brain arise not with each new migraine attack, but are the result of an ongoing process that occurs even during periods between attacks, Dr. Kruit said.
The study participants aged, making it difficult to tease out brain changes that are specifically attributable to migraine. That is because age, as well as hypertension and diabetes, are also known risk factors for white matter changes, Dr. Launer explained. Sixty percent of control females without migraine showed progression of white matter lesions as compared to 77 percent of those with migraine.
These findings add to the increasing amount of data that migraine, particularly in women, is progressively related small blood vessel changes, the researchers wrote in the paper.

Depression twice as likely in migraine sufferers

Depression twice as likely in migraine sufferers

Study finds the prevalence of depression and suicidal ideation much higher among individuals with migraine
TORONTO, ON — The prevalence of depression among those with migraine is approximately twice as high as for those without the disease (men: 8.4% vs. 3.4%; women 12.4% vs. 5.7%), according to a new study published by University of Toronto researchers.
In a paper published online this week in the journal Depression Research and Treatment, investigators reported that younger migraine sufferers were particularly at risk for depression. Women with migraines who were younger than 30 had six times the odds of depression in comparison to sufferers who were aged 65 and over, said lead author, Professor Esme Fuller-Thomson, Sandra Rotman Endowed Chair at the University of Toronto’s Factor-Inwentash Faculty of Social Work. Unmarried individuals and migraine sufferers who had difficulties with daily activities also had high odds of depression.
Data drawn from a representative sample of more than 67,000 Canadians, the 2005 Canadian Community Health Survey, were used to examine gender-specific associations between migraine and depression. More than 6,000 respondents reported that they had been diagnosed by a health professional with migraines. Consistent with prior research, the prevalence of migraines was much higher in women than men, with one in every seven women, compared to one in every 16 men, reporting that they had migraines.
The study also investigated the relationship between migraine and suicidal ideation.  For both men and women, those with migraines were much more likely to have “ever seriously considered suicide or taking (their) own life” than were those without migraines (men: 15.6% versus 7.9%; women: 17.6% versus 9.1%). Migraineurs under age 30 had four times the odds of lifetime suicidal ideation in comparison to migraineurs aged 65 and over. Other factors associated with suicidal ideation among those with migraines included unmarried status, lower household income and greater activity limitations.
Co-author and former graduate student Meghan Schrumm commented “We are not sure why younger migraineurs have such a high likelihood of depression and suicidal ideation. It may be that younger people with migraines have not yet managed to find adequate treatment or develop coping mechanisms to minimize pain and the impact of this chronic illness on the rest of their lives. The much lower prevalence of depression and suicidal ideation among older migraineurs suggests a promising area for future research.”
Dr. Fuller-Thomson adds that this study “draws further attention to the need for routine screening and targeted interventions for depression and suicidality, particularly among the most vulnerable migraineurs: Individuals who are young, unmarried and those with activity limitations.”
