Can Cannabis Help Prevent Dementia?

By Pat Anson, PNN Editor

People use cannabis for a variety of reasons. Some use it to relieve pain. Others use it to help them sleep, improve their appetite, or reduce anxiety and stress. Still others use cannabis because it makes them feel good.

A new study suggests there’s another unexpected benefit from consuming cannabis, especially when it’s used recreationally: It may help middle-aged adults ward of dementia.

Researchers at SUNY Upstate Medical University looked at health survey data that assessed the subjective cognitive decline (SCD) of over 4,700 U.S. adults between the ages of 45 and 64. Memory loss and confusion are symptoms of SCD, which is considered an early sign of dementia.

To their surprise, researchers found that participants who only used cannabis recreationally had significantly lower risk of SCD – as much as 96% less risk compared to non-users. Those who used cannabis for medical reasons or combined it with recreational use also had lower odds of SCD, but the difference was not statistically significant.

“We found that non-medical cannabis use was significantly associated with reduced odds of SCD in comparison to non-users. Several factors might explain this observation. Non-medical use of cannabis often contains THC, which has a psychoactive component that creates the ‘high’ sensation. Whereas CBD is non-psychoactive and often used for anxiety and chronic pain management,” the SUNY research team recently reported in the journal Current Alzheimer Research.

One likely reason for the disparity in SCD between recreational and medical users is that those who consume cannabis for health reasons may have comorbid medical conditions – such as diabetes, hypertension, cardiovascular disease and musculoskeletal disorders -- that raise their risk of dementia.

Another consideration is sleep. One of the primary reasons people use cannabis is to help them fall asleep faster and stay asleep longer. Recreational use of cannabis has the added benefit of improving sleep quality. A recent study found that insomnia is associated with a 51% higher risk of dementia risk.

The frequency of cannabis use and whether it was smoked, vaped or ingested had no significant connection to SCD risk.

Although the study found no direct cause-and-effect relationship between cannabis, SCD and dementia, researchers think it’s worth exploring further. More than six million Americans have Alzheimer’s disease or some form of dementia, a number that’s expected to double by 2050. 

“Despite the advancement of medicine and technology, dementia remains incurable and non-preventable. While some medications can slow symptom progression, they are only effective if started during early stages and cannot reverse its course,” SUNY researchers concluded. “Given the widespread use of cannabis in the U.S., it is imperative to pursue further research to understand the mechanism underlying the reduced odds of SCD among non-medical cannabis users.”

There’s an App for That

By Barby Ingle, PNN Columnist

Have you noticed that many healthcare companies, medical providers and support groups now have apps for patients?

A recent survey found that about 40% of U.S. adults use healthcare apps and 35% use wearable devices to track their fitness, sleep, diet and other health-related activities. The market for healthcare apps was estimated to be worth $10 billion in 2022 and is expected to grow to $41 billion by 2030.

There are some great “patient-centric” apps. Patient-centric or "person-centered care" means the technology approaches healthcare in a manner that directly involves patients. I have used apps to track my eating, hydration, movement, medications, sleep time and more. Some apps can also help you organize your medical care and recognize issues or changes needed in your medical records.

Patient Portal Apps

The patient portal apps I suggest below are typically set up by the provider, and then the patient can log in and check their records, set up appointments, and access other resources. There are many choices for medical providers to use for patient portals, but these seem to be the ones used the most:  

• HealthTap: This telehealth app connect patients with primary care doctors for online care. Patients can use HealthTap for checkups, prescriptions, lab tests, treatment plans, and specialist referrals. They take patients with and without insurance. Costs start as low as $15 a month, making this affordable for even those without insurance.

• MyChart: This one is my personal favorites and I use it often, as do most of my providers in Arizona. I used MyChart this morning to check on my appointments and to pay an outstanding balance. This app can also give friends and family access to your medical records if you choose. It is excellent for parents to take care of their children and other family members from one account. It will store your medical and lab records, and even some images from MRIs, x-rays, etc. There is transparency in who has accessed your medical records, so you will know which providers have this information.

• FollowMyHealth: This app allows patients to access their medical records, request prescriptions, schedule appointments, and send messages to medical providers and staff. FollowMyHealth can also connect with medical devices such as glucose, heart and blood pressure monitors, and digital scales.

Apps for General Health 

There are many apps for overall general health, with the most popular ones being Headspace, Talkspace, Doctor on Demand, Sleep Cycle, My Fitness Pal, Fooducate, Teladoc, Fitbit, Noom, mySugr, and WebMD.  I have used many of them, but I will focus on my top three:  

• Fitbit: I never considered using a Fitbit watch until I won one from the WEGO Health Awards (now Health Union). I quickly got more involved in tracking my life by using the device. I loved how it could track my movement, sleep and stress levels, and allowed me to put in notes on things such as hydration, migraines and gastrointestinal challenges. I also like Fitbit’s PurePulse, which tracks blood flow and heart rate. FitBit devices range from $80 to $300 each.

• Noom: This is a subscription-based app that helps users track their food intake and exercise. Noom uses psychology to help users develop healthy eating and physical activity habits to lose weight. It takes a lot of dedication and focus to use Noom successfully. I lost over 20 pounds using it. I am not very active physically, and they considered that in developing an individualized program for me as a chronic pain and rare disease patient. The app encourages you to think about food differently and change your eating habits so your body works better for you. The average subscription is $60 monthly.  

• Sleep Cycle: This app tracks and analyzes your sleeping patterns. It was helpful for me to take sleep data from the app to my primary care provider so he could better understand why I have trouble sleeping. I do not sleep consistently through the night, especially on high-pain days. It’s a good tool to figure out why you are struggling to sleep and how pain is affecting your internal clock or waking you up. The Sleep Cycle app is free to download, but a premium subscription costs $40 per year. I used the free accessible portions of the app at no cost.

Chronic Pain Apps

There are many apps that can help a patient track their pain levels, types of pain, whether treatment options are helping or hurting, and more. I used to do this the old-fashioned way with a journal, but having digital data to break it down scientifically for my providers was helpful once I started using pain-tracking apps. I have tried a few and heard others find them helpful as well.  

• PainChek: This app uses artificial intelligence (AI) and facial expressions to assess pain in people who cannot reliably communicate their pain levels, such as those with dementia or young children. PainChek uses a smartphone camera to analyze a person's face. The AI system then automatically recognizes and documents facial movements that indicate pain. It’s more of an objective tool for me, since I can speak about my pain, but for those who are voiceless, it could help their daily life and individualize their care. 

• Vivify:  This is a 28-day program for people with chronic back or neck pain that includes pain education, meditation, exercises, and guided walks through an app or website connection. Vivify also monitors patients remotely, allowing providers to create and manage wellness programs for their patients. Although the goal is to “overcome or remove chronic pain entirely,” I see this app as more of a tool for people to assist in their daily activities and motivate them to move.

• My Pain Diary:  This pain-tracking app reminds me of when I used to manually keep track of my pain before apps were available. It gives patients a way to document and track their pain triggers and symptoms. You can also use the data to print detailed reports that are easy to share with your providers. I like the color-coded calendar, graphs and searchable history. The app looks at the data and sees trends you may not notice yourself. The Gold Edition of My Pain Diary costs just $5.

• PainScale: This app was recommended to me by a friend. PainScale is made by Boston Scientific and helps users track their pain, suggests treatment options, and generate reports to providers. It can also provide information from the Mayo Clinic, WebMD and other trusted pain resources to help patients manage chronic pain triggers. This app is free to download.  

The apps mentioned above are some of the most used and trusted apps by patients and providers. Patient-centric apps have become an essential part of the healthcare industry. As technology and AI continue to advance, we can expect to see more of these innovative patient apps in the future.

Cannabis Helps Relieve Cancer Pain

By Pat Anson, PNN Editor

Good news for patients suffering from cancer pain or side effects from cancer treatment. Two new studies found that medical cannabis helps relieve cancer pain, and offer some lessons to non-cancer patients about which cannabis products might work best for them.

The first study involved 358 adult cancer patients enrolled in a cannabis registry created by the Quebec Medical College. The patients were being treated for a variety of different cancers and were referred to the registry by their doctors. The primary complaint of most was pain (72%), with others experiencing symptoms such as nausea, anorexia, weight loss, anxiety and insomnia.

Participants were assigned to one of three groups, using cannabis products that were high in tetrahydrocannabinol (THC), high in cannabidiol (CBD), or a balanced blend of THC and CBD. The cannabis was ingested orally, through inhalation or a combination of the two. Patients were monitored and assessed every three months for a year.

The study findings, published in the journal BMJ Supportive & Palliative Care, show that pain levels dropped significantly after 3, 6 and 9 months, with pain slightly worsening after 12 months. Patients using balanced THC-CBD products reported the most pain relief, and many were able to reduce their use of opioids and other medications.

A small percentage of patients suffered adverse events from cannabis, such as sleepiness, dizziness and fatigue. Only 5 patients had side effects so severe that they stopped using cannabis.

Researchers concluded that medical cannabis should have a role as a complimentary pain management option in cancer patients who don’t get adequate relief from conventional analgesics.

“We found MC (medical cannabis) to be a safe and effective treatment option to help with cancer pain relief. THC:CBD balanced products appear to perform better as compared with THC-dominant and CBD-dominant products. Furthermore, we observed consistent decreases in medication burden and opioid use in our patient population,” researchers said.

Less Pain = Better Cognition

The second study, by researchers at University of Colorado Boulder, involved 25 cancer patients being treated by oncologists at the CU Anschutz Medical Campus. The patients’ pain levels, sleep patterns, cognition and reaction times were assessed at the start of the study; and they were asked to select edible products from a cannabis dispensary, such as chocolates, gummies, tinctures and baked goods containing different ratios of THC and CBD.

After just two weeks of regular use, patients reported less pain, better sleep, and the unexpected benefit of improved cognition – they were able to think more clearly.

“When you’re in a lot of pain, it’s hard to think,” said senior author and cancer survivor Angela Bryan, PhD, a professor of psychology and neuroscience at CU Boulder. “We found that when patients’ pain levels came down after using cannabis for a while, their cognition got better.”

The improved cognition didn’t happen right away. Patients who used edibles rich in THC got high from it and their cognition initially decreased. But after a few days of regular cannabis consumption, a new pattern emerged. Patients reported improvements in pain, sleep and cognitive function, including reaction times.

“We thought we might see some problems with cognitive function,” said Bryan. “But people actually felt like they were thinking more clearly.”

Patients who ingested edibles high in CBD reported bigger improvements in sleep quality and pain intensity.

Bryan’s study, published in the journal Exploration in Medicine, is one of the first to assess the efficacy of cannabis purchased at dispensaries — rather than less potent government supplied cannabis or synthetic cannabis medications that are primarily used to treat nausea.

Bryan had just begun studying medical cannabis in 2017, when she was diagnosed with breast cancer. After surgery and chemotherapy, she looked to cannabis for pain relief as an alternative to opioids. Neuropathic pain is a common side effect from chemotherapy.

Bryan used her own customized regimen of potent THC products when pain was intense and took mostly CBD products when the pain was more manageable. She was not completely pain-free, but she didn’t take a single opioid during treatment. She hopes others will learn from her experience.

“I was extremely lucky because I had some knowledge about this. Most patients don’t,” Bryan said. “People are open to trying whatever they think might be useful, but there's just not much data out there to guide them on what works best for what.”

As many as 40% of U.S. cancer patients use cannabis, but only a third of doctors feel comfortable advising them about it.

Melatonin and Cannabis Products Often Mislabeled

By Pat Anson, PNN Editor

If you use cannabis for pain relief or take melatonin to help you sleep at night, you may want to check the label and ask the manufacturer just how accurate the list of ingredients is.  Or think twice before buying it.

Two more studies are raising doubts about the accuracy of label claims on cannabis products and melatonin supplements, which are often marketed with unsupported claims about their health benefits.

In the first study, published this week in JAMA, researchers analyzed 25 melatonin gummy products, including 5 gummies that also contained cannabidiol (CBD). Melatonin is a natural hormone produced by the brain at night to help induce sleep. Supplements containing synthetic melatonin and/or CBD are often marketed as products that improve sleep, reduce anxiety, and promote relaxation.

Researchers found that only 3 of the 25 gummies contained enough melatonin to be within 10% of the labeled amount – with one product containing 347% more melatonin than what was listed, a potentially dangerous amount. Another gummy contained no melatonin at all, just CBD.

“The great majority of melatonin gummy products were inaccurately labeled, with most products exceeding the declared amount of melatonin and CBD,” wrote lead author Pieter Cohen, MD, an associate professor at Harvard Medical School and an internist at Cambridge Health Alliance. “Given these findings, clinicians should advise parents that pediatric use of melatonin gummies may result in ingestion of unpredictable quantities of melatonin and CBD.”

Pediatric use is concerning because calls to U.S. Poison Control Centers about children ingesting melatonin have increased five-fold over the past decade, resulting in nearly 28,000 emergency room visits, over 4,000 hospitalizations and two deaths.

Researchers say it takes just 0.1 mg to 0.3 mg of melatonin to increase plasma levels beyond the normal nighttime range in young adults. The amount of melatonin found in the gummies was much higher, including one product containing 13.1 mg of melatonin.

“Consuming melatonin gummies as directed could expose children to between 40 and 130 times higher quantities of melatonin,” they said. “With respect to CBD, the drug is FDA approved to treat refractory seizures caused by 3 rare genetic disorders, but the FDA has not approved the use of CBD for any indication in healthy children.”

The JAMA report is believed to be the first U.S. study to quantify the amount of melatonin in over-the-counter supplements. A 2017 Canadian analysis of melatonin products had similar findings, with the actual dose of melatonin ranging from 17% to 478% of the amount listed on the label. Neither the U.S. or Canadian studies identified the melatonin brands that were tested.

Too Little THC

It wasn’t too much, but too little tetrahydrocannabinol (THC) that University of Northern Colorado researchers found in 23 cannabis flower products purchased at state-licensed dispensaries. The study findings, recently published in the journal PLOS One, show that nearly 70% of the flower samples had THC levels at least 15% lower than what was listed on their labels.

Inaccurate labeling has long been a problem in the cannabis industry. Some growers and merchants resort to “lab shopping” to seek out product testing laboratories that generate the most desirable results – which means inflated levels of THC.  There’s a financial incentive to do so, because cannabis products containing high amounts of THC usually sell at a higher price.

One of the flower samples, purchased at a Denver dispensary and sold under the brand name “OG Kush 2,” had only half the amount of THC listed on its label.  

“Given our results it is urgent that steps are taken to increase label accuracy of Cannabis being sold to the public. The lack of accurate reporting of THC potency can have impacts on medical patients controlling dosage, recreational consumers expecting an effect aligned with price, and trust in the industry as a whole,” researchers said.

“Although we have no power to change the current system, we hope highlighting this issue and educating consumers will affect the change needed to remedy inflated potency of flower products. Addressing this discrepancy will require both changes to the regulatory system and consumer awareness that reported THC potencies are frequently inflated.”

Although 38 states and Washington DC have legalized medical or recreational cannabis, there is little consistency in labeling, regulating or testing cannabis. The researchers called for more regulatory oversight of cannabis and standardized testing protocols.

UK Study Shows Chronic Pain Patients Benefit from Cannabis

By Pat Anson, PNN Editor

Chronic pain patients who used a variety of cannabis products experienced less pain, better sleep and improved quality of life, according to a new UK study that found the most improvement in patients who used oil-based cannabis products.

Researchers at Imperial College London assessed the safety and efficacy of cannabis in over 700 pain patients enrolled in the UK Medical Cannabis Registry. Participants were divided into three groups that used either oil-based cannabis, smoked or vaporized dried flowers, or a combination of both (CBMP) for six months. The oil-based products included extracts, lozenges and capsules.

The study findings, published in the journal Expert Review of Neurotherapeutics, show symptom improvement in all three groups, with patients using cannabis oil either alone or in combination with dried flower reporting the most improvement.

Researchers think the CBMP group derived the most benefit because the cannabis was ingested through two different administrative routes, one absorbed straight into the blood stream through inhaling (dried flowers) and the other slowly absorbed through the digestive system (oil-based cannabis).

“The findings in this study demonstrate treatment with oil-based, dried flowers, or a combination of both CBMPs are associated with statistically significant improvements in pain relief and sleep quality after 6 months in chronic pain patients,” researchers reported.

“Additionally, patients prescribed oils or both types of CBMPs experienced reduced anxiety and an improvement in their ability to perform daily activities. Patients prescribed a combination of both CBMPs recorded improvements in their self-care and mobility abilities. Collectively, this evidence signals that initiation of CBMP treatment is associated with improved HRQoL (health related quality of life).

In addition to symptom improvement, participants in the CBMP group reported a small reduction (3.28%) in their use of opioid analgesics.

About one in every four patients had an adverse side effect, such as fatigue, somnolence and dry mouth. Adverse events were more common in females, former cannabis users and cannabis naïve (new) users.  

A previous study of patients enrolled in the UK Medical Cannabis Registry found significant improvement in their pain, discomfort and sleep quality after using cannabis oil.

A recent survey of U.S. adults with chronic pain found that nearly a third have used cannabis for pain relief. Over half of those who used cannabis said it also enabled them to decrease their use of opioids and other pain medications.

Most Americans Losing Sleep Due to Pain

By Pat Anson, PNN Editor

Does pain keep you awake at night? A new survey found that a surprising number of Americans are unable to get a full night’s sleep because of “painsomnia.”

Almost 98% of U.S. adults surveyed by the Sleep Foundation say they experience pain at least one night a week. About 85% said pain costs them at least two hours of sleep each night, with the average respondent losing six hours of sleep per week.  

Back pain was the most common reason for painsomnia (56%), followed by neck pain (41%), head pain (32%) and knee pain (29%).

“Pain does not have to be extreme to keep us awake,” says Alex Dimitriu, MD, founder of Menlo Park Psychiatry and Sleep Medicine, and a member of the Sleep Foundation's medical-review board. “Even milder forms of pain can result in varying degrees of insomnia, resulting in trouble falling or staying asleep.”

Adults who live with pain average just 6.7 hours of sleep per night, below the recommended 7 to 9 hours. A recent meta-analysis of 31 studies found that sleep loss increases our perception of pain and creates a vicious cycle. Poor sleep leads to more pain and vice versa.

“When you can’t sleep well due to pain, this leads to more pain,” said Medhat Mikhael, MD, a pain management specialist and medical director of the Spine Health Center at Orange Coast Medical Center in Fountain Valley, CA. “You also become anxious about not sleeping enough, so you don’t sleep. Then you’re fatigued, so you feel a lot more pain.”

When asked to rate their pain on a zero to ten scale, 73% of respondents with chronic pain said their nightly pain was at level 5 or higher. Over half (57%) said they wake up at least three times during the night, and 41% say they wake up earlier than they’d like.  Experts say fitful sleeping is less restorative and heightens pain sensitivity.

“Sleep is as much about quality as it is about quantity,” Dimitriu says. “Falling asleep too late can push circadian rhythms into a delayed sleep-phase cycle. And waking too early can result in an advanced sleep phase cycle, where you get tired too early in the evening.”

What are people doing about their poor sleep? Over half of respondents (56%) who lose sleep to pain have taken sleep aids in the past month. Melatonin was the most popular (49%), followed by Benadryl (diphenhydramine) (23%).

A surprising number said connecting with others in pain support groups helps them sleep. Although only 1 in 5 pain sufferers say they’ve participated in support groups, 91% of those who did say interacting with other painsomniacs helped them learn how to better manage, understand or improve their sleep.

This Sleep Foundation survey was conducted online in June, 2022. Results are from 1,250 participants aged 18 and older who lived in the United States.

Study of Fibromyalgia Drug Continues Despite Disappointing Results

By Pat Anson, PNN Editor

New Jersey-based Tonix Pharmaceuticals says it will proceed with a Phase 3 study of a drug to treat fibromyalgia, despite disappointing results that caused the company to stop enrolling new patients.

Based on an interim analysis of the first 337 participants enrolled in the RALLY study, an independent data monitoring committee found that TNX-102 SL was unlikely to demonstrate a statistically significant improvement in pain compared to placebo. No issues were reported on the safety of the drug.

The finding of the monitoring committee is somewhat surprising, because Tonix recently reported results from another Phase 3 study, which found that TNX-102 SL significantly reduced pain compared to placebo and also improved sleep, fatigue and function in fibromyalgia patients.

“We are surprised and disappointed that the interim analysis did not support continued enrollment in this Phase 3 RALLY study, especially considering the previous Phase 3 RELIEF study, which had a similar design and achieved statistical significance on the primary endpoint,” said Seth Lederman, MD, President and CEO of Tonix. “These results underscore the difficulty in managing and treating fibromyalgia.”

Lederman said the company would continue its Phase 3 trial with the patients who are already enrolled and report the results in the fourth quarter of 2021. It will then determine its next steps.

TNX-102 SL is a sublingual tablet formulation of cyclobenzaprine hydrochloride, a muscle relaxant and anti-depressant that’s being evaluated as a daily bedtime treatment for fibromyalgia. The goal is to see if TNX-102 SL helps fibromyalgia patients sleep better.  In addition to fibromyalgia, TNX-102 SL is also being considered as a treatment for post-traumatic stress disorder (PTSD), alcohol use disorder and agitation in Alzheimer’s disease.

Fibromyalgia is a poorly understood disorder characterized by widespread body pain, fatigue, poor sleep and depression. The National Institutes of Health estimates about 5 million Americans have fibromyalgia. Most people diagnosed with fibromyalgia are women, although men and children can also be affected.

The FDA has approved only three drugs to treat fibromyalgia; the antidepressants duloxetine (Cymbalta) and milnacipran (Savella), and the anti-seizure medication pregabalin (Lyrica). Many fibromyalgia patients say the drugs are ineffective and have unwelcome side effects. A recent analysis found little evidence to support the long-term use of any medication or therapy to treat fibromyalgia.

Insomnia Drugs Risky When Taken With Opioids

By Pat Anson, PNN Editor

Medications commonly prescribed to treat insomnia significantly increase the risk of death for older adults if the drugs are taken with opioids, according to new study.

Zopiclone, zaleplon and zolpidem – collectively known as “Z-drugs” – are sold under brand names such as Ambien, Lunesta and Sonata. Z-drugs are sedative-hypnotics and act in a similar way as benzodiazepines, but are considered safer because they belong to a different class of medication.

But after reviewing the medical records of over 400,000 Medicare patients aged 65 and older, researchers at Vanderbilt University Medical Center found that Z-drugs are nearly as risky as benzodiazepines. Patients using benzodiazepines and opioids had a 221% higher risk of death from any cause, while those taking z-drugs and opioids had a 68% increased risk of dying.

Benzodiazepines such as Xanax and Valium are primarily used to treat anxiety. Until recently, benzodiazepines were often co-prescribed with opioids to pain patients, a practice that is now discouraged because both drugs suppress respiration, which can lead to an overdose.

"Our findings indicate that the risks of benzodiazepine-opioid use go well beyond the recognized hazards of overdose. They also suggest that the z-drugs, thought to have better safety than the benzodiazepines, in fact are dangerous when prescribed in combination with opioid pain medications," said Wayne Ray, PhD, professor of Health Policy at Vanderbilt and lead author of the study published in PLOS Medicine.

"Our findings add urgency to efforts to limit concurrent prescribing of benzodiazepines and opioids. They also suggest that targeted warnings are needed to advise older patients and their providers regarding the potential risks of taking z-drugs with opioids."

Last year the Food and Drug Administration ordering drug manufacturers to update warning labels for benzodiazepines to strongly caution patients and providers about the risk of abuse, addiction, dependence and overdose, particularly when the drugs are used with opioids or alcohol.   

In 2019, the FDA also ordered stronger warning labels for Z-drugs, but in that case it was to caution people about rare side effects such as sleepwalking, sleep driving and other risky behaviors.  

Study Finds Regular Exercise Reduces Migraine Triggers

By Pat Anson, PNN Editor

Two-and-a-half hours of moderate to vigorous exercise a week can significantly reduce migraine triggers like stress, depression and poor sleep, according to a new survey that found more than two-thirds of migraine sufferers do not get enough exercise.

“Migraine is a disabling condition that affects millions of people in the United States, and yet regular exercise may be an effective way to reduce the frequency and intensity of some migraines,” says lead author Mason Dyess, DO, a Senior Fellow at the University of Washington School of Medicine.

“Exercise releases natural pain killers called endorphins, helps people sleep better and reduces stress. But if people with migraine are not exercising, they may not be reaping these benefits.”

The survey involved 4,647 people diagnosed with migraine. About three-fourths of participants had chronic migraine, meaning 15 or more migraines a month. The others had episodic migraine, or up to 14 a month.

Participants completed a questionnaire about their migraines, sleep, depression, stress, anxiety and the amount of exercise they get each week.

Researchers then divided them into five groups based on their level of exercise: those who did not exercise; people who exercised up to 30 minutes per week; those who exercised 31 to 90 minutes; people who exercised 91 to 150 minutes; and participants who exercised more than 150 minutes per week.

Types of exercise that qualified as moderate to vigorous included jogging, very brisk walking, playing a sport, heavy cleaning and bicycling.

Researchers found that only 1,270 participants – about 27 percent -- reported the highest level of exercise. Those who got less than 150 minutes of exercise had increased rates of depression, anxiety and sleep problems:

• Depression was reported by nearly half of people who got no exercise, compared to 25% of those that exercised the most.

• Anxiety was reported by 39% of people in the no exercise group, compared to 28% of people in the high exercise group.

• Sleep problems were reported by 77% of people in the no exercise group, compared to 61% in the high exercise group.

Researchers also found an association between exercise and increased frequency of migraines. Among people in the no exercise group, nearly half had 25 or more headache days per month. That compares to only 28% of people in the high exercise group.

“There are new therapeutics available for migraine, but they are very expensive. People with migraine should consider incorporating more exercise into their daily life because it may be a safe and low-cost way to manage and minimize some of the other problems that often accompany migraine,” said Dyess.

Two-and-a-half hours a week of moderate to vigorous exercise, or 150 minutes, is the minimum amount recommended by the World Health Organization.

The study findings, which will be presented at the annual meeting of the American Academy of Neurology in April, have not yet been peer-reviewed or published. One weakness of the study was that participants self-reported their exercise minutes, rather than having their activity monitored with a device. It also only shows an association between exercise and migraines, and does not prove cause and effect. 

Tolerance Reduces Sleep Benefits of Medical Cannabis

By Pat Anson, PNN Editor

Getting a good night’s sleep can be a godsend to someone suffering from chronic pain. That’s why many pain patients are experimenting with medical cannabis to help manage their sleep problems.

But a small new study found that while cannabis initially helps with sleep, regular use leads to drug tolerance that causes even more sleep problems. A second study raises doubts about the use of cannabinoids in treating cancer pain.

Researchers at the Rambam Institute for Pain Medicine in Israel enrolled 129 volunteers over age 50 with chronic neuropathic pain. About half used medical cannabis for at least a year, either by smoking (69%), oil extracts (21%) or vaporizers (20%). The other half did not use cannabis.

Sleep problems were common among both groups of patients, with about 3 out 4 having trouble falling asleep or staying asleep.

Researchers found that cannabis users were less likely to wake up during the night, compared to those who did not use the drug. But over time the benefits of cannabis were reversed, and frequent users found it harder to fall asleep and woke up more often during the night.

The findings are published in the British Medical Journal's Supportive and Palliative Care journal.

“This study is among the first to test the link between whole plant MC (medical cannabis) use and sleep quality. In our sample of older (50+ years) chronic pain patients we found that MC may be related to fewer awakenings at night. Yet patients may also develop tolerance to the sleep-aid characteristics of MC,” researchers wrote.

“These findings may have large public health impacts considering the ageing of the population, the relatively high prevalence of sleep problems in this population along with increasing use of MC.”

The study was observational and did not establish a direct causal link between cannabis and sleep.  Another weakness is that the specific timing of cannabis use by participants was unknown. Taking cannabis before bedtime may have a stronger association with sleep. The researchers said their findings were preliminary and more larger studies were needed.

Cannabinoids Not Recommended for Cancer Pain

Another study published in the same medical journal found that cannabinoids do not reduce pain in patients with advanced cancer.

Researchers at the University of Hull in the UK reviewed data from five high-quality clinical studies involving 1,442 cancer patients and found that pain intensity was no different between those taking cannabinoids and those given a placebo.

Patients using cannabinoids also had nearly twice the risk of short-term side effects such as dizziness, drowsiness, nausea and fatigue. They were also more likely to drop out of studies.  

“For a medication to be useful, there needs to be a net overall benefit, with the positive effects (analgesia) outweighing adverse effects. None of the included phase III studies show benefit of cannabinoids,” researchers concluded.

“When statistically pooled, there was no decrease in pain score from cannabinoids. There are, however, significant adverse effects and dropouts reported from cannabinoids. Based on evidence with a low risk of bias, cannabinoids cannot be recommended for the treatment of cancer-related pain.”

The American Cancer Society takes a different view, pointing out that studies have found marijuana smoking can be helpful in treating nausea from cancer chemotherapy.  Other studies have also suggested that THC, CBD and other cannabinoids slow the growth of cancer cells in a laboratory setting.

Medical marijuana is legal in 33 In U.S. states and cancer is recognized as a qualifying condition in many of them.

Can Melatonin Put Your Chronic Pain to Sleep?

By A. Rahman Ford, PNN Columnist

Melatonin is popularly known as the sleep hormone. Less known is its potential to alleviate chronic pain and inflammation.

Melatonin is a natural hormone produced by the pineal gland in the brain. During the day the pineal gland is inactive, but at night it begins to produce melatonin and helps us sleep.

As a supplement, melatonin is widely promoted for its efficacy as a sleep aid. However, its role in reducing inflammation – a major contributor to chronic pain – may be much more important. Many chronic pain conditions are a result of underlying inflammation.

In a recent Nature article, melatonin was called a “master regulator” of inflammation. Several studies have shown that melatonin can regulate activation of the immune system, reducing chronic and acute inflammation.

Research shows that melatonin supplements can modulate inflammation by acting as powerful antioxidants and free radical scavengers. Uncontrolled free radicals in the body can lead to oxidative stress, which can cause inflammation and culminate in diseases that cause chronic pain.

There is a large body of evidence that melatonin is a potent antioxidant, even more potent than vitamins C and E.  It’s been successfully used to treat fibromyalgia and irritable bowel syndrome, diseases associated with high levels of oxidative stress.

Melatonin is also a strong antimicrobial, and emerging research shows that some chronic inflammatory conditions may be caused by infections. One study found melatonin effective in treating certain drug-resistant bacteria such as Staphylococcus aureus, Pseudomonas aeruginosa and Acinetobacter baumannii. Similar results were found when testing ten different pathogens, including Escheria coli and Salmonella typhinurium, with melatonin.

Melatonin and Chronic Pain

A therapeutic role for melatonin in the treatment of painful autoimmune conditions has been theorized.  A 2013 study noted that melatonin plays a role in the pathogenesis of conditions such as multiple sclerosis and systemic lupus. In animal models of these diseases, melatonin supplements were found to have protective effects. A 2019 review concurred, concluding that melatonin can serve as a new therapeutic target in treating autoimmune diseases.

A review of the scientific literature on chronic pain syndromes found evidence of melatonin’s efficacy as an analgesic in several conditions including fibromyalgia, irritable bowel syndrome and chronic back pain. Studies also showed melatonin’s effectiveness in treating cluster headaches ad tension headaches.

A small clinical trial of 63 females with fibromyalgia found that melatonin, alone or in combination with the antidepressant amitriptyline, significantly reduced pain when compared to amitriptyline use alone. The authors concluded that the melatonin treatment had a direct effect on the regulation of pain.

There has been some evidence that melatonin supplements can help reduce lower back pain. In a 2015 study, researchers found a significant reduction in pain intensity during movement and at rest in patients with back pain.

Melatonin has also been successful in treating migraines. In an open-labeled clinical trial of 34 patients suffering from migraine, 30 mg of melatonin given 30 minutes before bedtime was found to reduce headache intensity as well as frequency and duration, with significant clinical improvement after one month.

Although the scientific evidence is only slowly emerging, melatonin is a widely-available, inexpensive and safe supplement that may aid you in your fight against chronic pain.

How CBD Helped End My Insomnia

By David Eaton, Guest Columnist

Due to a decrease in my opioid pain medication (to fall within the CDC guideline), my pain level increased to the point that I was unable to sleep. Of course, lack of sleep affects your overall health and so I began a downward spiral and needed something to break that cycle.

My son, who has been suffering acute pain from scoliosis in his neck, was having similar insomnia issues. He tried CBD oil and recommended that I do the same.

I knew little about CBD, so I talked to the very knowledgeable and helpful manager of a local CBD store. His recommendation was that I begin by researching CBD myself and then talk about it with the doctor at my pain clinic -- advice that impressed me as being very responsible.

After spending a day or two reading online articles, including some here on Pain News Network, I ran the idea past the physician’s assistant at my pain clinic.  She thought it was a great idea and asked me to try it before my next appointment with her in 4 days.

I placed another call to the manager at the CBD store and he recommended starting with a CBD infused "candy bar." My wife went there the next day and paid $25 for a white chocolate, peach and hazelnut flavored candy bar containing 120 mg of CBD.

The chocolate bar was scored in such a way that it can be divided into 4 servings, each with 30 mg of CBD. The manager’s suggestion was for me to try a single piece the first night and then take one and a half sections the following 2 nights. So that's what I did. 

Prior to trying the CBD, I had experienced a lot of pain-induced insomnia and found it difficult to sleep for more than an hour at a time.  It was not uncommon for me to wake up 10 times during a 12-hour effort to sleep. 

Most people do not realize how important a good night's sleep is to your health and well-being.  After my insomnia got severe, I installed an app on my phone (Sleep as Android) to track how much I slept each night.

After taking my nighttime meds and my last "dose" of CBD chocolate, I fell asleep around 8 pm.  According to the sleep app, which amazed me by its accuracy, I slept until 3 am, waking up feeling very rested and refreshed.

I decided to stay awake long enough to write this article before going back to sleep at 4 am. I slept until 10:45 that morning.

In all, I got about eleven and a half hours of deep sleep over the course of about 13 hours!   

As far as I am concerned, the use of CBD to reduce my pain and promote relaxation is an overwhelming success. I will be investing in a bottle of CBD oil on my next trip to town.

A Day in the Life of a Chronic Pain Sufferer

By Katie Burge, Guest Columnist

My day usually begins around 3 a.m., whether I want it to or not.  No matter what time I went to bed or how tired I am, I wake up in those pre-dawn hours, overwhelmed by excruciating pain and trembling from a panic attack caused by the pain. I wake up because I hurt too bad to stay asleep.

Don't get me wrong. I'm happy enough just to wake up at all - but what I wouldn't give some time to actually get a good night's sleep.

I grab a cup of coffee and debate whether or not I can "afford" to take a pain pill that will give me some modicum of relief. I have to be extremely careful with my medication.  I can't just take a dose because I'm in agony and need it. I don't get enough to allow myself that luxury. My monthly prescription for pain medication allows me to survive semi-comfortably for just over half the month.

It feels like I'm on an evil roller coaster ride, where my pain levels off for 3 or 4 hours, then spikes exponentially over the next few hours until I can take another dose.

As my day progresses, I try to choose the optimum time to take my pain medication, depending on what I need (or attempt) to accomplish for the day.  I struggle to take a shower, do the dishes or fix something to eat. Some of my time is spent writing.

One of the most important things in my life right now is advocating for better treatment for all chronic pain patients. I would like to be physically able to go to the state capitol or even to Washington DC to lobby for more compassionate treatment and to convince the bureaucrats there that pain patients are not to blame for the "opioid epidemic."

But that will have to wait until I can get my own pain reliably controlled.

When I do sleep, I dream about being able to do theater again, travel somewhere other than to a doctor's appointment or to run -- do any of a hundred things I’d like to do if I could exist away from the recliner that I essentially live in. It's the only place where I can find some degree of comfort.

For the past 20 years I have been dealing with increasingly severe chronic pain from a plethora of conditions like degenerative disc disease, failed back syndrome, spinal stenosis, spondylolisthesis, osteoarthritis, myofascial pain syndrome and fibromyalgia.

Any one of these conditions can generate enough pain to make a grown man cry like a little girl.  Combined, they can transform a normally relaxing shower into a study in torture -- where the droplets of water hitting my skin feel like daggers.

KATIE BURGE

Over the years, I think I've tried every treatment offered by medical science, as well as many alternative treatments - anything that might have the potential to take my pain down a notch or two. Once, I even started studying medical texts, trying to gain enough of an understanding of the logistics of pain that I could design a visualization exercise that would help me control it.

I never wanted to end up taking opioids. The pain medication I take is what's known as a "short-acting" or "immediate release" opioid, a type of drug that's actually designed for temporary acute pain, not round-the-clock chronic pain like I have.

Unfortunately, doctors are afraid to use the extended release medications that were actually designed for continuous pain.  This is the result of legal and political pressure from politicians who think they can solve the opioid epidemic by torturing pain patients. Somehow, they believe they can keep recreational drug users from overdosing by denying pain sufferers the legitimate medical use of opioids.

Short-acting opioids offer pain relief for a period of about four hours.  I am expected to make it a full 8 hours inbetween doses. That's where the evil roller coaster comes in. I take my medication, which gives me up to 4 hours relief, and then the pain spikes over the next 4 hours — making me feel worse than I did to start with.

It's up and down, up and down all day long and it's exhausting! If I was allowed to take the medication as it was made to be taken (every 4 hours), it would afford me more enough pain control that I could build a more normal life for myself. Doctors used to say it was safer and better that way, but that was before they became so afraid.

When it starts getting dark each day, I can feel the panic rising in my chest because soon it will be time to sleep and that means more pain. The depression and shame tend to crop up when it gets dark as well. The depression comes from being so isolated. As a person in pain, you spend a lot of time alone.

The shame comes from just being in pain in the first place, as society seems to tell us that we should be able to control our pain mentally, without medical or pharmaceutical intervention.

This is my day... EVERYDAY.

It's starting to get dark now, and the panic is boiling up again.

Why a Bad Night’s Sleep Causes More Pain

By Pat Anson, PNN Editor

It’s no secret that chronic pain makes sleeping difficult. And lack of sleep often makes pain worse.  But how exactly does poor sleep cause more pain?

For the first time, scientists at the University of California, Berkeley, have identified neural glitches in the sleep-deprived brain that can intensify and prolong pain. Their findings, published in the Journal of Neuroscience, help explain the self-perpetuating cycles that contribute to pain and sleep loss.

“Anyone who has had persistent back pain knows that they don’t sleep well when they are in pain. They also know that when they don’t sleep well, it hurts more the next day,” said senior author Matthew Walker, PhD, a UC Berkeley professor of neuroscience and psychology.

"If poor sleep intensifies our sensitivity to pain, as this study demonstrates, then sleep must be placed much closer to the center of patient care, especially in hospital wards.”

In a small study involving 25 healthy young adults, Walker and his colleagues found that nerves that process pain signals and activate the body’s pain relief hormones are disrupted by insufficient sleep. Study participants were given MRI brain scans twice – once after a good night’s sleep and once after a night of no sleep – and then subjected to a thermal pain test in the laboratory  

“We found some surprising changes. The sleep-deprived brain seems to let more pain in,” Walker said.

Brain imaging showed increased activity in the brain's somatosensory cortex, but there was less activity in the nucleus accumbens, a region of the brain's reward circuitry that increases dopamine levels. Dopamine is a neurotransmitter that’s been called the “feel-good hormone” because it is associated with feelings of euphoria and happiness.

Another key brain region found to slow down in the sleep-deprived brain was the insula, which evaluates pain signals and prepares the body to respond.

"This is a critical neural system that assesses and categorizes the pain signals and allows the body's own natural painkillers to come to the rescue," said Adam Krause, lead author of the study and a doctoral student in Walker's Center for Human Sleep Science lab at UC Berkeley.

To further test the sleep-pain connection, researchers surveyed more than 230 adults of all ages nationwide. Respondents were asked to report their nightly hours of sleep, as well as their day-to-day pain levels. The results showed that even minor shifts in sleep patterns were correlated with changes in pain sensitivity.

"The results clearly show that even very subtle changes in nightly sleep -- reductions that many of us think little of in terms of consequences -- have a clear impact on your next-day pain burden," Krause said.

"The optimistic takeaway here is that sleep is a natural analgesic that can help manage and lower pain," said Walker. "Yet ironically, one environment where people are in the most pain is the worst place for sleep -- the noisy hospital ward."

Walker's goal is to work with hospitals to create more sleep-friendly patient facilities.

"Our findings suggest that patient care would be markedly improved, and hospital beds cleared sooner, if uninterrupted sleep were embraced as an integral component of healthcare management," he said.

Several previous studies have found that getting a good night’s sleep helps reduce sensitivity to pain. Researchers in Norway measured pain sensitivity in more than 10,000 adults and found a strong link between pain and insomnia.

Another study in Norway found that women who have trouble sleeping are at greater risk of developing fibromyalgia – although it’s not clear if there’s a cause and effect relationship between the two symptoms.

Pain Researchers Say Let Sleeping Dogs Lie

By Pat Anson, PNN Editor

Most people with chronic pain recognize the importance of good sleeping habits. A night spent tossing and turning can mean a day full of aches and pains.

For that reason, dog lovers are often told they shouldn’t sleep with their pet. One survey of pet owners found that over half said their dogs tend to wake them at least once during the night. Sleeping with a pet can also be unsanitary and lead to behavioral problems.   

"Typically, people who have pain also have a lot of sleep problems, so usually if they ask their healthcare provider about a pet, they're told to get the pet out of the bedroom. But that standard advice can actually be damaging," says Cary Brown, PhD, a Professor of Rehabilitation Medicine at the University of Alberta.

Brown is co-author of a small study, published in the journal of Social Sciences, in which seven chronic pain patients who slept with their dogs were asked about their pets’ impact on their sleep. Brown said the response was "overwhelmingly positive."

"They liked the physical contact with their dogs—cuddling before bed, and how it distracted them from feeling anxious about being alone at night. They felt more relaxed and safer, so they weren't anxious as they were trying to sleep," said Brown.

"A sense of relaxation and caring are emotions that release positive hormones in our bodies that will help us sleep better."

Having our pets sleep with us can also help ward off loneliness. A dog can take on a significant role for the chronically ill when friends drift away and social circles shrink.

“I’ve got my buddy and I’ve got my companion hanging out with me and I don’t get that loneliness,” one patient said.

“I always have got somebody to cuddle and make me feel loved when I am lonely and in pain and when I am trying to sleep,” said another.

Researchers say doctors need to have deeper conversations with their patients before suggesting that a pet sleep somewhere else.

"When you ask people to remove an animal they are in the habit of co-sleeping with, it could have consequences the health-care provider hasn't considered," Brown said. "For some people with chronic pain, their relationship with their pet could be the only one they have and the comfort that dog or cat produces would be lost."

For some patients, it’s also a reciprocal relationship. They try to help their dogs sleep and comfort them when they have pain.

“She [the dog] has days when she experiences lots of pain, I make myself get down on the floor at her level …. I will sit with her and talk with her and very softly, very calmly, I make a point of massaging her ever so gently,” one woman said. “I find this brings down her heart rate, she’s not in pain, the pain is starting to go down. I can physically see the changes in her and eventually she nods off to sleep.”

Although dogs have been living with people for thousands of years – and often sleeping with them – surprisingly little is known about the emotional and physical benefits of sharing a bed.

“This small study shines a light on this important and yet neglected area of research. It reveals that for these participants their dog appears to enhance their sleep in many ways. Further research is warranted to explore more fully the ways in which pet dogs influence sleep for people with chronic pain,” said Brown.
