NEW YORK (Reuters Health) – Patients diagnosed with migraine are at increased risk of experiencing tinnitus, according to Taiwanese researchers.
In a paper online July 12 in JAMA Otolaryngology-Head & Neck Surgery, Dr. Hwang of Dalin Tzu Chi Hospital stated that in such patients “a history of migraine might lead to inner ear symptoms, especially tinnitus, later in their lifetime, even though they do not have episodes of migraine anymore.”
in Chiayi, and colleagues stress that “migraine” is not a synonym for “headache.” That’s simply one of many symptoms and they sought to determine whether cochlear disorders might be another.
The team examined a Taiwanese insurance database and identified 1,056 patients with migraines diagnosed between 1996 and 2012. They were compared with 4,224 propensity-matched controls from the same database.
Subgroup analysis showed that after adjustment, the hazard ratio for tinnitus was significantly higher among people with a history of migraine. There was no significant increase in the risk of sudden deafness or sensorineural hearing impairment.
In light of these findings, Dr. Hwang continued, “inner ear symptoms might be a variant of migraine presentation” and he and his colleagues “propose a new diagnosis of ‘cochlear migraine’ for this situation.”
Richard katesmark from the Surrey headache & migraine clinic in Ewell comments;
” Migraine has long been known to often be associated with dizziness and balance symptoms, & I have also noticed that tinnitus seems to be present more often than one would expect in Migraine patients ( as are other other neurological symptoms ), this report provides a very high level of evidence that confirms what I have suspected : that there is a relationship between migraine activity and the development of auditory (hearing) symptoms, including tinnitus .”
The following was taken from Reuters Health –
Even when a headache specialist refers migraine patients for proven behavioral treatments like biofeedback, relaxation training or cognitive behavioral therapy ( C.B.T) , barely half of them go, suggests a recent U.S. study.
Of 69 migraine sufferers treated at a large academic headache practice and referred for behavioral therapy, just 57 percent got as far as making an appointment with the behavioral practitioner, researchers found.
The patients who ignored their doctor’s recommendation cited time limitations as the main barrier to treatment. Concerns about cost and insurance coverage were also an issue. And some were skeptical about whether the treatment would work; others worried about the potential stigma of seeing a psychologist, the study team reports in the journal Pain Medicine June 5.
Opioids are still being prescribed as the first line of treatment for migraines when evidence shows that behavioral therapy is more effective and safer in treating migraines
“I don’t think that people realize that behavioral therapy alone can result in a 50 percent reduction in headache days. It’s not only effective alone, but when combined with medications it can have a synergistic effect. Behavioral therapy improves patients’ quality of life : they perceive less pain, miss less work and can enjoy their activities again,” said Dr. Nauman Tariq, director of the Johns Hopkins Headache Center in Baltimore, who was not involved in the study.
Richard katesmark comments. “ It is not a great surprise that many people do not try behavioural approaches to help with their headpain, In my opinion this is either because they are simply unaware of the benefits or because they are under the impression that ‘talking’ therapies are only for ‘mad’ people. It is important to realise that from a brain perspective they can change the perception of pain & may be very effective for many chronic migraine sufferers . Therefore C.B.T. is just one of the therapies that may be recommended at the Headpain relief clinic here in Surrey “
Good news ; Cheyham Lodge headache & Migraine clinic is now open all day Saturday & sunday.
As the initial appointment is for 2 hours I realise it can be difficult to fit this in during the working week . Therefore appointments can now be made at weekends .
Hopefully this will be valuable to headpain sufferers locally in Ewell, Epsom, Banstead, Chessington , Cheam, Kingston plus other areas of Surrey and beyond.
Once again new research has confirmed what most headache specialists already knew anecdotally; For patients with migraine, repetitive yawning may accompany or precede a migraine attack.
The study was published in the February issue of Headache.
It involved a cross-sectional study of 339 patients with long-standing migraine (mean age, 35.5; 301 women), 154 (45.4%) reported repetitive yawning during migraine attacks: 11.2%, in the premonitory phase; 24.2%, during headaches; and 10%, both in the premonitory phase and during headaches.
Why is this useful?
Firstly it further illustrates that migraine is more than just a headache disorder, that various parts of the brain are affected in different ways & at different times throughout the migraine ‘experience’.
Secondly it can be a valuable early signal to the patient to identify an impending attack so that they may take appropriate actions to treat/manage their migraine early, whether it be via medication &/or behaviour ( change environment, rest, relax, eat, drink etc ).
It is well recognised that early interventions have a much better chance of preventing a full blown migraine attack.
The problem is that early symptoms/signs, including yawning, that may accompany/ precede a migraine attack may be subtle, and patients may misattribute these symptoms to other causes, for example, too little sleep or too little caffeine. Patients therefore need to be vigilant in order to notice them.
Fortunately there are usually ‘groups’ of subtle warning signs that occur together, making them easier to identify as warnings of an impending migraine, for example;
Changes in level of energy.
Pins & needles, tingling, numbness( usually head/face/arms, but can be anywhere).
Sensitivity to light/sound/touch.
Aching/pain in the neck, face, jaw etc.
Hunger pangs or loss of appetite.
Unpleasant ‘tastes’ in the mouth.
Mood changes/ irritability / depression etc.
Digestive discomfort/ nausea.
Changes in bowel or bladder function/frequency.
So my advice to patients is: If you find yourself experiencing any of the above at odd times, you should take note because it’s possible that a headache is oncoming, and you may want to be prepared with your medication or make behavioral changes that you know have helped in the past.
However it is worth stressing that not all migraines have accompanying symptoms such as those mentioned above.
Also if you have had migraines before without the above symptoms, but then start to develop them, it is important to seek the opinion of a headpain specialist.
Menstrual migraines that occur in the days following menstrual bleeding may be related to low ferritin caused by blood loss rather than to estrogen fluctuations according to research led by Anne H. Calhoun, MD, from the University of North Carolina and Carolina Headache Institute–Research, Durham. As she states;
“End menstrual migraine (EMM) is a common complaint in women evaluated for menstrual related migraine, yet these migraines occur many days after the estrogen withdrawal that precipitates menstrual-related migraine,”
“[We] believe that end menstrual migraine is not hormonally mediated, but rather that it is causally related to menstrual blood loss, resulting in a brief relative anemia with consequent migraine,” the researchers add.
Menstrual Blood Loss
The study was prompted by the researchers’ clinical observations that some patients being treated for regularly occurring menstrual migraine experienced the migraines at the end of menstruation.
“We suspected a relationship to menstrual blood loss and have been routinely checking ferritin levels for this complaint for a few years,” they report.
They evaluated data on 119 consecutive patients seen over 6 weeks at the clinic.
Among 85 women with regular menses who were appropriate for evaluation, 30 (35.3%) had EMM. Their mean EMM duration was 2.6 days, with the headache graded as severe on at least one day.
Of the 30 patients, as many as 28 (93.3%) showed levels of ferritin, an intracellular protein that stores iron and releases it in response to tissue demand, to be below the generally accepted lower desirable limit of 50 ng/mL (mean, 21.9 ng/mL). Of those women, as many as half had levels below 18 ng/mL, the established minimum for women.
“While adequate iron levels are certainly important, adequate iron stores are equally important, [and] with inadequate ferritin, these iron stores can quickly be depleted,” the authors note.
The researchers also note that chronic headache is a recognized symptom of low ferritin levels.
The authors call for larger epidemiologic studies to confirm the prevalence of EMM and to better characterize the disorder.
They recommend the following diagnostic criteria for EMM: (1) predictable migraine headache (with or without aura) that (2) occurs immediately after or toward the end of menstrual bleeding.
Richard Katesmark comments ; “ Various mineral & vitamin deficiencies have been identified over the years as potential causes, or contributors, to migraine. Intuitively it would make sense that regular post-mentrual headpain may be related to iron levels. So if you fit the above criteria for EMM it may be worth trying a good quality ferritin supplement for a few months & see if it helps “

Results of a new study presented at the international congress of Headache & migraine has found that people with migraine who exercise can reduce the frequency of their attacks, but doing so requires a really good workout a couple of times a week for the most benefit.
Researchers at the University of Basel, Switzerland, report that both moderate continuous exercise (MCT) and high-intensity interval training (HIT) resulted in a significant reduction in migraine days among migraineurs, with HIT being associated with the highest reduction.
“HIT is a safe training modality for migraineurs showing more pronounced effects on migraine attack reduction, cerebrovascular health indices and maximal oxygen uptake compared to MCT,” the researchers, with lead author, Alice Minghetti, MSc, Department of Sport, Exercise and Health, University of Basel, Switzerland, concluded. “Thus, supervised aerobic exercise should be considered a complementary preventive and treatment strategy for migraineurs.”
To test the efficacy of exercise in reducing migraine frequency, the researchers randomly assigned migraineurs to a 12-week regimen of HIT (n = 8), MCT (n = 8), or a control group with no exercise training (n = 8).
The HIT and MCT groups participated in exercise twice a week for 12 weeks. HIT consisted of 4 consecutive sets of running exercise for 4 minutes at 95% of maximal heart rate followed by 3 minutes at 75% of maximal heart rate, for a total exercise time of 28 minutes per session.
MCT consisted of running for 45 minutes at 70% to 75% of maximal heart rate.
Richard Katesmark comments; “It has been known anecdotally for sometime that regular exercise is often beneficial for migraine sufferers, so some research confirming this is welcome.
Of course there will be exceptions as some types of migraine can be triggered by vigorous exercise.
Also it is very important people should gradually build their fitness levels (taking professional advice where necessary), & not suddenly launch themselves into intensive exercise programmes.”
I have already discussed the possible links between migraine & low Vit D levels ( see winter Migraines below ). A possible Link between low Vit D & chronic headache has now been suggested.
Researchers from the University of Eastern Finland have now published a study investigating the relationship between vitamin D status and the risk for frequent headache.
They assessed 2601 men, aged 42-60 years in 1984-1989, from a population-based cohort derived from the Kuopio Ischemic Heart Disease Risk Factor Study.
They made cross-sectional associations of self-reported frequent headache, defined as weekly or daily headaches and blood vitamin D levels.
In those with frequent headache, the average serum vitamin D concentration was 38.3 nmol/L; while in those without frequent headache, the average vitamin D concentration was 43.9 nmol/L.
Those in the lowest serum vitamin D quartile had 113% higher odds for frequent headache compared with those in the highest quartile.
The authors concluded that low serum vitamin D concentrations are associated with a markedly higher risk for frequent headaches in men.
Richard Katesmark suggests reading below post on winter migraines for further advice & info on importance of Vit D.
Added Sept 2017 -Post script; Yet another bit of research ( this time from India ) has found that Patients suffering from chronic tension type headaches are more likely to have low blood levels of Vit D than non-headache controls.
Whenever there is a heatwave, such as the one where having a moment, there is always an increase in the number of referrals to my clinic. I would like to comment on some of the reasons for this.
• Sunlight & reflected glare; One of the commonest reasons for increased headache/migraine frequency in summer. Wearing a brimmed hat/baseball cap to shield the eyes from direct sun and a pair of effective sunglasses (making sure their dark enough and of decent quality) are obvious precautions, not to mention keeping to the shade when possible.
Less obvious but also important is reflected light on computer screens, desks
and other surfaces. Use of blinds/curtains can clearly help as can repositioning office
& home furniture.
N.B; there is a brand of sunglasses called `Migralens` (http://www.migralens.com/) which are designed specifically for migraine sufferers which specifically cut out the type of light thought to trigger migraines.
• Dehydration; This is a common cause of headaches in summer. Most people underestimate the extra fluids they need to drink during hot weather especially if taking even gentle exercise.
Exact amounts are difficult to give as it varies with age, activity levels and the environment, but here are some guidelines;
In `normal` weather; Men should drink at least 3 litres/5 pints (about 13 cups) per day. Women- at least 2.2 litres/4 pints (about 9 cups)per day.
In `hot` weather these amounts should be increased by a minimum 1.5 to 2 litres, ie an extra 2-3 pints every day that it is hot. This needs to be even more if exercising, where you may be losing as much as 2 litres per hour as perspiration!!
Note that thirst can be a relatively late sign of dehydration, so drink before you become thirsty! And remember the extra fluid should not be taken in the form of drinks which contain caffeine (coffee, tea & certain soft drinks -always check the label)
Whilst on the subject of drinking it is worth noting that in the hot weather people’s consumption of alcohol also often increases. Needless to say if, like many people, alcohol is one of your triggers this would cause an increase in headaches/migraine.
• Mineral losses; Linked to fluid loss/ dehydration is loss of minerals (electrolytes) leading to changes in concentration ratios between certain important body chemicals. In some people this might increase the tendency to headaches/migraines. Therefore it may be worth taking extra mineral supplements such as dioralyte during particularly hot weather.
• Heat and humidity; Clearly difficult to influence, but the judicious use of fans/dehumidifiers/portable air conditioning units can help.
• Sleep disturbance; In my opinion this can be a very important factor in `heatwave headaches`. We all know it is hard to sleep when it is hot at night and the sleep we do get is often disturbed and therefore of poor quality. Again there’s little one can do about this apart from using fans etc as mentioned above. However if you notice you are waking earlier it may also be due to the increased morning light in which case the fitting of `blackout` curtains /blinds is advisable.
• Missing meals/ change of diet; Most people eat less when it is hot, perhaps even skipping meals, this can lead to low blood sugar levels which ( as discussed in another blog below ) is often a factor in causing headaches/migraine. So try to eat regularly despite the heat.
• Hay fever ; Generally this tends to be worse in the spring and summer and occasionally it will trigger/aggravate headaches if originating in the sinuses( see earlier blog below for info on sinus headaches)
So if you are one of those people whose headaches seem worsen as soon as the Bar-B-Q weather arrives, one or more of the above could be the cause. Try making a few changes as mentioned and see if it helps.
As winter draws in it would seem an opportune moment to discuss vitamin D and migraines.
Some of you maybe aware that it has been estimated that between 10 & 20% of people in the UK may have lower than ideal Vitamin D levels in their bodies (indeed some studies suggest it may be as high as 60-70% during the winter months).
In addition to this some research has shown a possible link between low Vitamin D & chronic migraine. Furthermore individuals with low vitamin D have been shown to be more likely to suffer chronic pain in general and to be less responsive to many common pain relievers.
Vitamin D is vitally important too many of the bodies metabolic pathways (the most well known being ensuring bone health). Some is obtained Directly from the diet (egg yolks, cheese, oily fish, mushrooms), but most is synthesised from x which can be converted into Vitamin D In the skin when is it exposed to UVB rays in bright daylight.( it does not have to be direct sunshine)
It is thought that the combination of poor diet (low in vitamins), wearing high factor suncream, and covering up during the summer, combined with short daylight hours in the winter, is resulting in chronically low vitamin D levels in a large percentage the population ( especially those who live in the northern hemisphere).
Therefore if your migraines/Chronic headaches seem to be worse during the winter months it may be worth considering whether you are vitamin D deficient.
What are the signs?
General symptoms associated with low vitamin D status Include:
Lack of energy and fatigue
Headaches and migraines
Poor immune system/Vulnerability to infections(colds/flu etc)
Generalised muscle aches and pains
( n.b. Clearly the above are all non-specific symptoms and can have many other causes.)
It is possible to have your Vitamin D status checked via blood tests, however you could simply try taking vitamin D supplements for a few of months & see if you feel any better.
Needless to say it also makes sense to ensure your basic diet is healthy. In addition during the darker months try and get out to ensure as much daylight as possible (or if this is not possible purchase a decent lightbox -use of which helps replace UVB rays).
For vitamin D, the recommended intake is 600-800 IU daily for adults ( 400- 600iu for children), not exceeding 4000 IU daily. Assuming no problems ( see below) it should be taken for at least 3 months
Always buy a good make of supplement ( I recommend Solgar) . I prefer Vit D3 ( cholecalciferol ) which is the natural form of Vit D.
Vitamin D Warnings.
Vitamin D could cause an allergic skin reaction..
This vitamin may also affect your blood sugar levels. If you have diabetes, your Dr may need to monitor you while you’re taking vitamin D.
Also, tell your doctor if you currently have, or have ever had, or take medications for any of the following:
High or low blood pressure
Kidney problems and kidney stones
An immune disorder
Heart disease or other heart problem
Check with your doctor if you have any misgivings about taking this or any other supplement.
Possible Signs of overdose
Confusion or disorientation
Weight loss or poor appetite
Nausea, vomiting, or constipation
As its the new year I thought I’d give you a brief summary of what has happened in headache research in 2016 in the medical world.
A large research program reanalyzed the results of 20,000 patients included over a number of different randomized trials, to compare triptans with placebo and other treatments. The rate of being pain-free after triptan intake was only somewhere between 18% and 50%. Although this seems rather unimpressive, the triptans were still superior in comparison with other migraine medications.
Clearly better medications need to be developed (especially for patients who have contraindications for triptans or for whom side-effects are unacceptable)
The most promising new drugs in the pipeline for migraine and cluster headache has been in the use of antibodies against calcitonin gene-related peptides. When the results of phase 2 trials in episodic migraine and chronic migraine were published the responder rate, defined as a reduction of migraine frequency of at least 50%, was achieved by one half of the patients.
Importantly the tolerability so far appears to be excellent. and there have basically been almost no side effects. All of these drugs are now in phase 3 randomized trials for episodic and chronic migraine, & also for episodic and chronic cluster headache. Hopefully next year, further information will be published to confirm how effective and well tolerated these new drugs are.
Another interesting study investigated the optimal duration of botulinum toxin for the treatment for chronic migraine. Investigators treated patients for 1 year and then stopped the treatment. It turned out that about one half of the patients did so well that they no longer needed botulinum toxin, whereas the other half deteriorated again and treatment had to be continued.
(nb there has also been some data showing that botulinum toxin might also be effective in patients with trigeminal neuralgia. If confirmed by further trials this has the potential to help sufferers who cannot use or tolerate the usual medication)
There was a new published paper on closure of patent foramen ovale (PFO) in patients who have migraine and migraine with aura, suggesting it had little, if any, benefits.
There was also an interesting but small study in cluster headache to treat acute attacks with a civamide nasal spray, which seemed to be effective. A phase 3 trial is now ongoing.
Further trials have had positive results for transcutaneous stimulation of the vagus nerve in cluster headache.This method is safe and well tolerated, and is now being investigated in frequent episodic migraine, chronic migraine, and cluster headache, compared with sham stimulation.
