Even the best migraine medications work for only about half of the people who try them. In the next decade or so, advances in pharmacogenomics, neuroscience, and artificial intelligence will allow us to predict who is going to respond to which drug. This will eliminate the trial-and-error approach we have to use now.
German researchers led by Dr. Uwe Reuter just published a study that attempts to predict who is going to respond to injections of CGRP monoclonal antibodies (mAbs) that are used for the prevention of migraines. These drugs include erenumab (Aimovig), galcanezumab (Emgality), and fremanezumab (Ajovy). The fourth drug in this family that is given intravenously, eptinezumab (Vyepti) was not available in Germany at the time of the study.
They compared super-responders (patients with 75% or greater reduction of monthly headache days) with non-responders (patients with 25% or lower reduction of monthly headache days after trying all three mAbs). Of 260 patients with chronic and episodic migraine they evaluated, 11% were super-responders, and 10% were non-responders.
Non-responders were more likely to have chronic migraines. Super-responders were significantly more likely to report good improvement of their acute migraine headache with a triptan. Non-responders were more likely to have depression and overuse acute medications.
It was interesting that only 10% of patients were non-responders. The authors explained this by the fact that they had to fail all three mAbs to be considered non-responders. An earlier German study showed that one-third of patients who did not respond to erenumab did respond to galcanezumab or fremanezumab.
The low number of super-responders to mAbs could be due to the fact that the German government pays for this treatment only if there is treatment failure or intolerable adverse events with all first-line preventives (beta-blockers, topiramate, flunarizine, amitriptyline and for chronic migraine, also OnabotulinumtoxinA, or contraindications to those. In the large clinical trials that led to the approval of mAbs, there was no such requirement and the results were much better.
Another study recently published by Sait Ashina and others in Rami Burstein’s group at Harvard showed that people who have increased skin sensitivity between migraine attacks (allodynia) are more likely to respond to galcanezumab.
These studies describe only trends and at this time have limited practical application. Patients who are depressed, overuse acute drugs, suffer from chronic migraines, or have interictal allodynia may still respond to mAbs. This information, however, may lead to more accurate prediction models when it is combined with genetic, imaging and other new data.
Read MoreOn March 10, I will be speaking on the Treatment of a Refractory Headache Patient at the annual meeting of HCNE in Greenwich, CT. One of the seven broad strategies I will be speaking about is trying multiple drugs within each therapeutic category. For example, if you did not respond to one beta-blocker, a different one might work better or have fewer side effects. Here is a part of a recent email from a former patient that supports this idea.
“For over fifty years, I have had migraines. Ever since Imitrex came out and I started to take it, I would get a migraine every day! We thought it might be rebound headaches from the Imitrex, but it was not. I tried every kind of medicine, and I mean EVERY. Nothing worked, and I just figured this was the way it would be until I died.
This summer, my hand was hurting and the doctor prescribed Celebrex. It did not help my hand, but my migraines WENT AWAY!!! Yes, after 50 some-odd years, no migraines. I thought it was a fluke, but no… my migraines are gone.
I take a Celebrex every morning after breakfast. If I even start to feel a headache, I take 2 Advil, and the headache is gone for the day. Every once in a while, I do get a migraine and I will take sumatriptan, but it is rare.”
Celebrex, or celecoxib, belongs to the NSAID family. It is somewhat different from other NSAIDs in that it is a selective COX-2 inhibitor. This means that it has fewer gastrointestinal side effects (ulcers, heartburn, etc.). Many people find that one NSAID works for an acute migraine much better than another – naproxen is better than ibuprofen, or diclofenac is better than naproxen, etc. This also holds true for the use of NSAIDs in the prevention of migraines. Meloxicam, indomethacin, aspirin, mefenamic acid, and others have been reported to be uniquely effective for some of my patients.
You can read about almost every drug in every category in the second edition of my latest book, The End of Migraines: 150 Ways to Stop Your Pain.
Read MoreIn a recent blog post, I wrote about the benefit of different types of exercises for the relief of migraines and other types of headaches. It mentioned that strength training may be more beneficial than aerobic (cardio) exercise. A study just published in Nature Communications suggests that the time of day when you exercise also matters. Not specifically for headaches but for “all-cause and cardiovascular disease mortality”.
This was a very rigorous study of 92,139 UK participants over an average of 7 years of follow-up which added up to 638,825 person-years. The timing of exercise was recorded by an activity tracker (accelerometer). Moderate-to-vigorous intensity physical activity at any time of day was associated with lower risks for all-cause, cardiovascular disease, and cancer mortality. However, the morning group (5:00 – 11:00), midday-afternoon (11:00 – 17:00), and mixed timing groups, but not the evening group (17:00-24:00), had lower risks of all-cause and cardiovascular disease mortality.
This study suggests that exercising before 5 PM has more health benefits than exercising after 5. It is likely that this may also apply to the relief of migraines and other headaches.
Read MoreIn a post last August, I mentioned that zinc could possibly extend the duration of the effect of Botox. A new report by Chinese neurologists in Headache describes their findings of an inverse association between dietary zinc intake and the occurrence of migraine in American adults.
The researchers used the data from a five-year study conducted by the CDC to assess the health and nutritional status of Americans. Data were collected using a computer-assisted dietary interview system which proved to be very reliable. Over 11,000 adults were included in the analysis of zinc intake. These subjects were divided into quintiles, according to their zinc intake. The data were adjusted for various confounding factors. These included age, sex, race, ethnicity, smoking status, body mass index, and others.
People in the lowest quintile were at least 30% more likely to suffer from migraine compared to people in the other four quintiles. Associaion does not mean causation and this study does not prove that taking zinc will prevents migraines. However, a few small studies did show the benefit of taking a zinc supplement in migraine patients.
Checking your blood for zinc levels before taking a supplement would be ideal. However, there is very little downside to taking 10-25 mg of zinc daily even if you don’t know your zinc level.
Zinc is very important for the normal functioning of the immune system, it possibly prevents macular degeneration, and has many other benefits. Taking too much zinc can cause serious side effects. The effects of zinc toxicity are mostly due to the lowering of copper levels.

Thank you, Lisa Robin Benson for a kind review of my book. This is a video review on the Migraine.com website.
Many of my colleagues have written very positively about my book. It is even more gratyfing to hear that patients and patient advocates also find it useful.
Read MoreInsomnia is a very common problem. Sleep aids, over-the-counter and prescription have been proven to be harmful if taken long-term. They even raise the risk of Alzheimer’s.
A small dose of melatonin (300 mcg, or 0.3 mg) can help better than the usual 3 mg dose sold in most stores. You can also try valerian root and definitely adhere to sleep hygiene. This includes no reading or watching TV in bed, no screens for at least an hour before bedtime, no eating or exercising within two hours of going to bed, and sleeping in a cold room (65 to 68 degrees). Going to bed at the same time also helps.
If you still can’t fall asleep, try visualization. Actually, you don’t just use your visual memory but engage all the senses. This post was prompted by a WSJ article on this topic, A Happy Memory Can Help You Fall Asleep, if You Know How to Use It.
I usually imagine myself on a beach in a hammock under a tree, feeling a warm breeze on my body, seeing a beautiful view of the beach and the ocean, smelling fragrant flowers, and hearing the sound of waves lapping at the shore.
Once you find your happy place and can vividly recreate it, always use the same setting without variation. This way you will fall asleep within minutes.

Migraine surgery is controversial. I would not consider it until most of the less invasive options have been tried. In my latest book, I give migraine surgery a score of 3, on a 1 to 10 scale. This rating may not be fair because clinical trials suggest that it can be very effective for some patients.
So, when is a referral to a surgeon warranted? Dr. Lisa Gfrerer is highly qualified to address this topic. She will speak on January 25th at a dinner of the NY Headache Club, an informal gathering of headache specialists who practice in the greater NYC area. If you are a headache specialist and would like to attend, send me a message. The meeting is not open to the lay public.
Here is Dr. Lisa Gfrerer’s short bio.
Dr. Gfrerer is an Assistant Professor in Plastic and Reconstructive Surgery at Weill Cornell Medicine (WCM). She received her MD degree at the Medical School of Vienna prior to completing a PhD in Genetics at the Harvard Stem Cell Institute. She graduated from the Harvard Integrated Plastic Surgery Residency Program and completed the Advanced Peripheral Nerve and Microsurgery at the Massachusetts General Hospital (MGH). Clinically, her focus is peripheral nerve surgery including headache surgery, treatment of nerve pain and compression, breast reinnervation, as well as advanced nerve reconstruction for restoration of motor and sensory function after an iatrogenic and accidental injury. She has built a multi-institutional and multidisciplinary research program for headache surgery, breast/chest reinnervation, as well as functional nerve disorders and nerve pain. As an affiliate of the Massachusetts Institute of Technology (MIT) she has further focused on innovation and device development to enhance peripheral nerve regeneration.
Read MoreDaily multivitamin use was compared to cocoa extract in more than 2,200 people over 65. After three years, taking a cocoa extract had no benefit while taking a multivitamin led to a significantly slower age-related cognitive decline. This included measures of global cognition, memory, and executive function.
Many physicians discourage their patients from taking a multivitamin. They should stop. There is little downside to taking a multivitamin. It is very inexpensive and safe. Many people also feel that if they eat a well-balanced healthy diet they should not need to take vitamins. Unfortunately, that is not the case. Even foods that are considered healthy are often processed, stored for a long time, or grown in depleted soil. Another problem is that as we age our body loses its ability to absorb vitamins and minerals (as well as protein, which is a different topic).
Taking a multivitamin should be a standard recommendation for those over 65. Many younger individuals need supplements as well. Ironically, a healthy diet (especially vegan or vegetarian) is often deficient in vitamin B12. Many young people whom I see for migraine headaches are deficient in vitamin D and magnesium. The role of vitamin D is also often underappreciated by primary care doctors. Multiple studies have shown that your vitamin D level should be not only within the normal range but in the upper half of the normal range for your brain to function normally. Most people who died of COVID had low vitamin D levels. And I’ve written many times about the importance of magnesium – just search this blog.
Ideally, to approach this problem scientifically, you should have your vitamin and mineral levels checked. This will allow you to take only those vitamins that you are deficient in. the difficulty is that there are too many vitamins to check and the insurance companies often refuse to pay for these tests. Taking at least a multivitamin is a reasonable alternative.
Read MoreOpportunities & Challenges in the Management of Headache is one of the two annual courses organized by the Diamond Headache Clinic Research & Educational Foundation. This year, it will be held in San Diego from February 16th through February 19th.
The other annual event, Headache Update 2023 will be held in Orlando, Fl from July 13th through July 16th. Both courses have been always well attended and have been receiving very high marks from the attendees.
It’s been my privilege to participate in these annual courses over the past 25 years. This year I will be speaking on February 17th on Nutritional Approaches and Alternative Therapies in Migraine.
Read MoreHolidays are again upon us. There are many reasons why people experience more migraines this time of year. Family drama, all the delicious unhealthy food, and alcohol. A report just published in the journal Headache brings some good news. Scientists proved that alcohol does not trigger migraines.
The researchers evaluated the digital diaries of 493 migraine sufferers who reported drinking alcohol. They used sophisticated statistical analysis including standard deviations, Bayesian statistics, Markov Chain Monte Carlo simulations, and the like, to show that there was no correlation between drinking alcohol and developing a migraine the next day.
If you still insist that alcohol gives you migraines, to paraphrase Groucho Marx, who are you going to believe, the scientists or your own lying eyes?
Another amusing paper comparing red wine with vodka as a trigger of migraines was published years ago by British researchers in The Lancet
Migraine patients who believed that red wine but not vodka triggered their attacks were challenged either with red wine or vodka. It was a blinded study – patients were not told what they were drinking. Vodka was diluted to equivalent alcohol content, and both were “consumed cold out of dark bottles to disguise colour and flavour”. And indeed, only wine triggered a migraine attack. A group of French doctors responded to this study in a letter to the editor. They stated that the only thing this study proved was that the Brits can’t tell wine from vodka.
Read MoreMultiple posts on this blog have described clinical trials that prove the benefit of exercise for the prevention of migraine headaches.
Simplifying the statistics, compared to no exercise, strength training was 3.55 times more effective, high-intensity aerobic exercise was 3.13 times more effective, and moderate-intensity aerobic exercise was 2.18 times more effective.
For general health and for the prevention of migraines, 2-3 weekly sessions of strength training and 2-3 sessions of aerobic exercise would be an ideal regimen. As I mentioned in a recent post, an additional benefit of exercise is a larger brain volume. The only other intervention that has been shown to expand the brain and prevent its shrinkage with age is meditation.
Exercise and meditation are the first two recommendations on my list of top 10 treatments described in my latest book, The End of Migraines: 150 Ways to Stop Your Pain.
