Functional MRI (fMRI) studies have shown that people with migraines have altered functional connectivity and activation patterns in pain-processing brain regions like the insula, thalamus, somatosensory cortex, as well as visual cortex. Some patients also have changes in the default mode and salience networks involved in attention and stimulus processing.

A study published this month by Chinese researchers in the Journal of Headache and Pain reports on connectivity changes in people with vestibular migraines.

They found abnormal resting-state functional connectivity in brain regions involved in multi-sensory and autonomic processing as well as impaired ocular motor control, pain modulation, and emotional regulation.

Until now, there has been little practical application for fMRI findings. However, with the help of Omniscient Neurotechnology, we have just started using fMRI data to better target our treatment with transcranial magnetic stimulation (TMS). TMS applied to motor and visual cortices has been reported to help relieve migraine headaches. We have also found it effective in a significant proportion of patients who did not respond to various other treatments. We have not yet accumulated enough data to determine if fMRI-guided TMS treatment is superior to TMS administered over a predetermined set of targets.

The main obstacle to wider use of TMS in clinical practice is the cost. TMS is approved by the FDA and is covered by insurance for the treatment of anxiety and depression, but not migraines or pain. fMRI is an expensive research tool and is also not covered by insurance. Hopefully, the NIH and other research foundations will provide the funds needed to study this promising treatment.

Medication overuse or rebound headaches can occur as the result of excessive intake of caffeine, opioid analgesics, and short-acting barbiturate drug, butalbital (contained in Fioricet, Esgic and similar drugs). These three substances not only worsen migraine headaches, they are also addictive. Two of my patients with medication overuse headaches were able to stop the offending drugs with the help of repetitive transcranial magnetic stimulation (rTMS).

One patient, a 51-year-old man, had his migraines under control with Botox and infusions of eptinezumab (Vyepti) until he sustained a head injury with a skull fracture. His migraines worsened and he became disabled. A variety of therapies failed to reduce his pain. His pain was partially relieved by 60 mg of oxycodone a day, although he still was unable to work. After six weekly sessions of rTMS he was able to start reducing his oxycodone intake and after eight, he completely stopped it. He was able to return to work with the help of injections of fremanezumab (Ajovy).

Another patient, a 50-year-old woman, had been taking butalbital with caffeine and acetaminophen (Fioricet) for 20 years. The number of pills increased over time and for the previous several years, she had been taking 10 to 12 tablets every day. She was also receiving Botox injections, infusions of eptinezumab, and taking rizatriptan (Maxalt), 10 mg three times a day as well as 60 mg of nortriptyline, 12 mg of tizanidine nightly and atogepant, 60 mg. She had tried a wide variety of other treatments but was unable to reduce her Fioricet intake. Despite her persistent migraines, she was able to take care of her family. After three weekly sessions of rTMS she reduced her Fioricet intake to 3-4 a day, by the third month she was taking one a day, and after 6 months she was completely off it. She was also able to stop atogepant and tizanidine and reduced her nortriptyline to 25 mg.

In addition to helping relieve pain and migraines, rTMS has shown promise in the treatment of addiction, particularly in addressing withdrawal symptoms, depression, and cravings. While the use of rTMS for addiction is still relatively recent and not yet FDA-approved, some studies have demonstrated positive outcomes. For instance, a double-blind study showed that individuals receiving rTMS therapy for cocaine addiction had a higher rate of abstinence compared to those who received standard treatment. rTMS for addiction is still considered experimental, and more research is needed to fully understand its long-term effects and optimal treatment parameters.

We now offer transcranial magnetic stimulation (TMS) for migraines and other neurological conditions

Neurologists frequently find themselves managing patients resistant to standard treatments due to limited proven therapies for many neurological conditions. Some patients cannot tolerate or have contraindications to medications, particularly for such common disabling conditions like migraine and chronic pain.

One promising treatment is transcranial magnetic stimulation (TMS). It is a proven procedure for anxiety, depression, obsessive-compulsive disorder (OCD), smoking cessation, and acute migraines. TMS utilizes magnetic fields to stimulate nerve cells in the brain that are underactive or reduce the excitability of overactive cells. TMS can change the flow of information between different parts of the brain in various neurological conditions. Published reports show the potential benefit of TMS in fibromyalgia, neuropathic pain, cluster headaches, facial pain, trigeminal and other neuralgias, back pain, insomnia, memory disorders, tinnitus, post-concussion syndrome, post-traumatic stress disorder (PTSD), restless leg syndrome, and long COVID. The evidence for the efficacy of TMS for these neurological disorders, however, is still limited.

Single-pulse TMS is approved by the FDA for the acute treatment of migraines with aura. The patient uses a portable device during the aura phase to self-administer a single pulse of TMS to the back of the head. This can abort the attack. Repetitive TMS (rTMS) has been studied for the prevention of migraines and other types of pain. It appears effective, but compared to depression trials, migraine studies were relatively small and the FDA has not cleared rTMS for the treatment of migraines. This means that insurance companies are not likely to pay for this “off-label” use of TMS.

rTMS is generally considered safe and well-tolerated, with side effects typically mild and temporary, including scalp discomfort, headaches, and facial twitching. More serious side effects like seizures and mania are very rare.

Before starting TMS, patients undergo a physical and mental health evaluation. The coil placement and dose are determined in the first session. During a TMS session, patients sit in a comfortable chair with earplugs. An electromagnetic coil is positioned near the scalp, delivering short magnetic pulses to specific brain regions involved in processing pain and other information. Patients feel and hear rapid tapping on their scalp that continues, on and off. Patients are awake and alert during the entire procedure. There are no limitations to activities before or after the treatment.

Treatment length varies from 20 to 45 minutes, depending on the stimulation pattern and number of sites stimulated. The frequency of treatments also varies – anywhere from daily for several weeks, to once a week. After the initial period of more frequent sessions, some patients require weekly or monthly sessions to maintain the effect. It may take a few weeks to see noticeable effects.

TMS is a good choice for people who have not responded to multiple standard therapies, people who do not want to take drugs, those who also suffer from depression and anxiety, and pregnant women. Sufficient evidence suggests that TMS is as safe in children as it is in adults, with studies indicating its effectiveness in treating depression in adolescents.

PTSD biomarkers

Researchers have identified four blood biomarkers that show promise in predicting, diagnosing, and monitoring treatment response for posttraumatic stress disorder (PTSD). These biomarkers could lead to more accurate methods of screening for PTSD, allowing for early intervention and prevention strategies. Additionally, they could help monitor treatment progress, identify different subtypes of PTSD, and enhance our understanding of the underlying mechanisms of the disorder.

The study was conducted by the PTSD Systems Biology Consortium, initiated by the Department of Defense, and involved approximately 45 researchers. The team analyzed blood samples from 1,000 active-duty Army personnel from the Fort Campbell Cohort (FCC), who were assessed before and after deployment to Afghanistan in 2014.

The researchers focused on four biomarkers: glycolytic ratio, arginine, serotonin, and glutamate. They categorized the participants into four groups based on their PTSD symptoms, resilience levels, and clinical assessments. The findings revealed that individuals with PTSD or subthreshold PTSD had higher glycolytic ratios and lower arginine levels compared to those with high resilience. Additionally, participants with PTSD exhibited lower serotonin and higher glutamate levels. These associations were independent of factors such as age, gender, body mass index, smoking, and caffeine consumption.

The study results require further validation. The researchers also aim to determine the optimal time to screen soldiers for PTSD, considering the psychological challenges that arise around 2 to 3 months post-deployment. Moreover, they recognize the need for gender-specific biomarkers to improve the clinical assessment of female soldiers, given the increasing number of women serving in combat roles.

Ultimately, these findings may apply to the civilian population experiencing PTSD.

Structural brain connectivity predicts pain

In a recent post, I mentioned a study in which researchers using functional MRI (fMRI) were able to link functional connectivity within the default mode network (DMN) and between DMN and executive control network (ECN) with the degree of disability in migraine patients.

In a new study published in the journal Pain, researchers examined the brains of patients with mild traumatic brain injury (mTBI) using fMRI imaging to understand the brain networks associated with early acute pain following a motor vehicle collision. Here are some key findings:

The properties of the brain’s white matter explained a significant portion of the variation in pain experienced after mTBI. This suggests that certain brain features make patients more likely to report higher levels of pain after the injury.
These white matter connections are associated with physiological and psychological characteristics related to pain sensitivity. The interactions between these connections and parameters of sensory testing and pain sensitivity can explain about one-third of the variability in pain.
The connectivity patterns in the brain’s white matter do not change over time, as observed up to a year after the injury. The same connectivity measures collected shortly after the injury and at six months post-injury can predict the level of pain reported by patients at the six-month mark.
The study further indicates that the strength of white matter connections in the sensorimotor, thalamic-cortical, and default-mode networks is associated with pain severity. These findings highlight the involvement of these brain networks in pain perception and suggest that connections within these networks can influence the experience of pain.

Over the past decade, scientists have been increasingly interested in functional connectivity, which is a way of finding networks in the brain that are related to particular activities, including resting. One of the most prominent networks is the default mode network.

The DMN is most active when the brain is at rest. When the brain is directed towards a task or goal, the default network deactivates. The DMN involves low-frequency oscillations of about one fluctuation per second.

The DMN is thought to be involved in a variety of cognitive functions, including self-awareness, social cognition, memory, thinking about the future, and daydreaming. The DMN is also thought to be involved in some psychiatric disorders, such as depression, post-traumatic stress disorder, obsessive-compulsive disorder, schizophrenia, and others.

The findings of this study suggest that the brain’s white matter networks plays an important role in pain perception, and that understanding these brain-pain relationships may lead to new treatments for pain in individuals with mTBI.

These brain networks are not fixed and we already have tools to improve their function. Meditation is one of the most effective and accessible such tools. Meditation has been shown to increase connectivity between different brain regions, including those involved in pain perception. It has also been shown to reduce the activity of pain-related brain regions. In addition to meditation, other things that people can do to improve the function of their brain networks and reduce pain include exercise and sleep.

Pandemic worsens headaches in children

Worsening of headaches in children is one of many deleterious effects of the pandemic and measures to control it. A survey of children in a headache clinic at the Children’s National Hospital in Washington DC by Dr. DiSabella and his colleagues showed that 46% of children had worsening of their migraine headaches during the pandemic.

They also reported much higher rates of anxiety, depression, and stress. Two-thirds of children reported that they exercised less. This could be one of the contributing factors since exercise has been shown to reduce the frequency and the severity of headaches.

What this survey did not explore is the effect of family stress and the presence of child abuse. Reports of child abuse have actually declined during the pandemic because most of these reports come from teachers. Chronic migraines and chronic pain are much more common in patients with a history of being physically, emotionally, or physically abused. PTSD from other causes has a similar predisposing effect and many children and adults have been traumatized by the pandemic.

Some children (as well as adults) report improvement of their headaches during the pandemic. My patients tell me that because they do not have to commute, they have more time to exercise, meditate, cook healthy meals, and get more sleep. I see this in a small proportion of patients. A larger group did worse with additional factors being worsening of headaches due to COVID and in a very small number, COVID vaccines.

A publication of the American Headache Society, Headache, The Journal of Head and Face Pain, has just published Dr. Allan Purdy’s most generous review of my new book, The End of Migraines: 150 Ways to Stop Your Pain.

I am very grateful to Dr. Purdy and to my many colleagues who wrote endorsements for this book.

Self-publishing allows me to set a low price of $3.95 for the ebook version. It also makes it easy for me to regularly update it. Self-publishing, however, means that, unlike my previous three books, this one does not have the promotional help of a big publisher. If you read the book, please write a review on Amazon and spread the word to other migraine sufferers.

Exercise speeds recovery from a concussion

Researchers at SUNY Buffalo and University of Manitoba studied the effect of exercise on recovery from a sports-related concussion in 103 adolescents. The results were published in JAMA Pediatrics.

The participants were enrolled within 10 days of a concussion. Half of the kids were given a stretching program and the other half, aerobic exercise on a treadmill. The intensity of aerobic exercise was subthreshold, or just below the level where it caused any post-concussion symptoms and was determined individually for each participant. Both stretching and aerobic exercise were performed for 20 minutes every day for a month. Those who did aerobic exercise recovered in 13 days, while those who did stretching exercise, in 17 days. There were no complications in either group.

This was the first randomized controlled trial of exercise, although prior observational studies also showed that early return to physical activity is beneficial for recovery from a concussion.

Cognitive rest is also not necessary after a concussion, but the activities should be also subthreshold and not too strenuous, which can worsen symptoms and delay recovery.

Other useful strategies include intravenous magnesium, cognitive-behavioral therapy, and Botox injections.

FDA approves the first blood test to diagnose concussion

Chronic migraine, Head trauma, post-traumatic headache

The news headlines are filled with stories of professional football players suffering from brain damage, but you do not to have to participate in sports to sustain a concussion – it is an everyday occurrence. In the US, in 2013 there were 2.8 million concussion-related emergency room visits and hospitalizations with 50,000 people dying from brain injuries. Three out of four concussions are mild. However, even mild concussion can cause impaired thinking or memory, poor concentration and emotional problems.

The U.S. Food and Drug Administration has recently approved the first blood test to evaluate concussion in adults. The diagnosis of concussion or in medical lingo, mild traumatic brain injury (mTBI), has been based purely on the description of symptoms by the patient, neurological examination, including the 15-point Glasgow Coma Scale, and brain imaging, such as CT scan to detect brain damage or bleeding. The majority of patients with a concussion have normal MRI and CT scans. This new blood test will help health care providers decide if a CT scan is necessary. This will avoid unnecessary scans which expose patients to radiation. It should also save money.

The Brain Trauma Indicator developed by Banyan Biomarkers, Inc. works by measuring levels of proteins, known as UCH-L1 and GFAP, that are released from the brain into blood and measured within 12 hours of head injury. Levels of these blood proteins after mTBI can help predict which patients may have brain lesions visible by CT scan and which won’t. Test results can be available within 3 to 4 hours.

The FDA based their approval on the data from a study of 1,947 patients with a suspected concussion. The Brain Trauma Indicator was able to predict the presence of intracranial lesions on a CT scan 97.5 percent of the time and those who did not have intracranial lesions on a CT scan 99.6 percent of the time.

It is not clear how this test will be used in the real world. If someone is sick enough to be brought to an ER, they are likely to get a CT scan, which is faster and avoids the 3-4 hour wait for the blood test results and the added cost of the blood test. People with a mild concussion who are not taken to an ER will not need the test because they are very unlikely to have visible brain injury on the CT scan. If symptoms persist for a while and the patient comes to our headache clinic, we obtain an MRI scan, which is more informative and avoids radiation, although it is more expensive.

The effect of post-traumatic headaches on the brain

Alternative Therapies, Botox, Chronic migraine, Head trauma, post-traumatic headache

Chronic pain is known to alter the structure of the brain. Mayo Clinic researchers used MRI scans to examine brains of 29 patients with post-traumatic headaches and compared their scans to those of 31 age-matched healthy volunteers. The average frequency of headaches was 22 days a month. Patients with post-traumatic headaches were found to have thinning of several areas of their cerebral cortex which are responsible for pain processing in the frontal lobes. Cortex covers the surface of the brain and contains bodies of brain neurons. Drs. Chiang, Schwedt, and Chong, who presented their findings at the annual meeting of the International Headache Society held last month in Vancouver, also discovered that the thinning was correlated with the frequency of headaches.

This study did not address possible treatments, but it would make sense that with better control of headaches, this brain atrophy might be reversible. To treat post-traumatic headaches we often use Botox injections, which have been shown to help posttraumatic headaches. Even though Botox is approved only for chronic migraines, many patients with post-traumatic headaches do have symptoms of migraines and can be diagnosed as having post-traumatic chronic migraines (without such a designation insurance companies may not pay for Botox). We also check RBC magnesium, CoQ10 and other vitamin levels, which are often low in chronic headache sufferers and if corrected, can lead to a significant improvement. Epilepsy drugs and anti-depressants can also help.

While the above mentioned treatments can help headaches and potentially could reverse brain atrophy, there is only one intervention that has been shown to increase the thickness of the brain cortex on the MRI scan. This intervention is meditation. And this effect was demonstrated in several studies. An 8-week course of mindfulness-based stress reduction led to a measurable increase in the gray matter concentration of certain parts of the brain cortex. A pilot study of migraine sufferers showed that meditation has a potential not only to restore thickness of the brain, but also to relieve migraines.

In one of my previous blog posts that described a sceintific study of meditation, I mentioned several ways to learn meditation: Free podcasts by a psychologist Tara Brach an excellent book, Mindfulness in Plain English by B. Gunaratana, and several apps – Headspace, 10% Happier, and Calm. You can also take an individual or a group class, which are widely available.
