Show 1462: Using Focused Ultrasound Against Parkinson Disease and Tremor

Most medical interventions are either pharmacological–prescribe a drug–or surgical–remove or repair the offending body part. If those approaches are inappropriate, doctors long for a different technology. In this episode, we discuss the development of a relatively new noninvasive technology, focused ultrasound. Doctors use it to treat conditions such as Parkinson disease or essential tremor. It may also be used for tumors in other parts of the body.At The People’s Pharmacy, we strive to bring you up‑to‑date, rigorously researched insights and conversations about health, medicine, wellness and health policies and health systems.

Using Focused Ultrasound: Most people are familiar with ultrasound being used as a diagnostic tool. They also know about using a magnifying glass to focus a ray of sunlight. With the proper technique, this could light a small fire. In focused ultrasound, the surgeon uses an acoustic lens to target ultrasound waves very precisely inside the body. Dr. Neal Kassell, our guest expert in this episode, is a neurosurgeon. He has used focused ultrasound primarily to treat brain tumors. Treatments require from several hundred to several thousand ultrasound waves. But doctors have used focused ultrasound to treat over 180 medical conditions. Regulatory authorities around the world have approved its use to treat 35 different conditions. The first to get such approval was uterine fibroids. This technology has been used to offer noninvasive interventions for 22 years. Now, people with Parkinson disease could choose focused ultrasound as an alternative to deep brain stimulation. There are approximately 250 sites in the US that are able to offer this technology to patients. How Focused Ultrasound Works: Dr. Kassell described how ultrasound works for problems as dissimilar as liver tumors or essential tremor. There are multiple mechanisms, but scientists have concentrated on three: First, the beams of ultrasound generate heat that can destroy tissue where they are focused. So, tumor or tissue destruction is the first mode of action. Second, ultrasound involves the use of very tiny bubbles. These can be created to hold drugs. If a doctor were treating cancer, that might be a chemotherapeutic agent. But rather than exposing the entire body to the same level of medication, with focused ultrasound the microscopic bubbles trap the drug and release it only when exposed to the targeted beams. That means a high concentration of medicine where it is needed and very low concentrations elsewhere. Third, focused ultrasound appears to have an impact on the immune system. As a result, patients being treated with immunotherapy such as Keytruda get a much better result when it is combined with focused ultrasound. This approach has been shown to improve the response rate. Adopting Focused Ultrasound May Lag: Doctors and healthcare systems have customary patterns of practice, referral and reimbursement. Introducing focused ultrasound into the mix may disrupt these. Insurance companies might save money over the long run if they covered this long-lasting intervention. Perhaps they will find before long that they get a better outcome for a lower cost. Where focused ultrasound is finding more purchase is among veterinarians treating companion animals (dogs and cats) who also suffer from hard-to-treat malignancies. With the OneHealth approach, veterinary medicine shares what it learns from such treatments with healthcare providers treating humans. One might not imagine essential tremor as responding to this type of treatment, but 25,000 patients have already been cured. This entails separate treatments on two different sides of the brain, with the sessions separated by six to nine months. The durability of the effect is very good. Bobby Krause Describes His Patient Experience: Bobby Krause was dismayed to be diagnosed with young-onset Parkinson disease at the age of 42. The drugs his doctors prescribed had intolerable side effects, and he felt depressed at not being the father he wanted to be for his young sons. He was excited to learn that focused ultrasound treatments have been delivered to about 30,000 Parkinson disease patients around the world. At least 75 percent have experienced significant improvement that lasts at least five years. Although he was not eligible for the first clinical trial he heard about, he jumped at the chance to be treated a few years later at the University of Pennsylvania. In 2022, his doctors delivered three sonication treatments in one day. The results were amazing; among other visible effects, he regained an inch of height that had been compromised by the tight spasms of his back muscles. This is a story you will want to hear! This Week’s Guests: Neal F. Kassell, MD is the founder and chairman of the Focused Ultrasound Foundation. https://www.fusfoundation.org/ This is a unique medical research, education, and advocacy organization created as the catalyst to accelerate the development and adoption of focused ultrasound and thereby reduce death, disability, and suffering for patients. He was a Professor of Neurosurgery at the University of Virginia from 1984 until 2016 and the co-chairman of the department until 2006. He has contributed more than 500 publications and book chapters to medical literature and is a member of numerous medical societies in the United States and abroad. In April 2016, Dr. Kassell was appointed by Vice President Joe Biden to the National Cancer Institute’s Cancer Moonshot Blue Ribbon Panel. Dr. Neal Kassell, director of the Focused Ultrasound Foundation Bobby Krause is the founder of the Be Still Foundation, a nonprofit dedicated to empowering patients and families affected by Essential Tremor and Parkinson’s disease. Inspired by his own journey with tremors, Bobby champions awareness, advocacy, and financial support for life-changing treatments like Focused Ultrasound, helping restore hope and dignity to those in need. https://youtu.be/LWOEwfcmLzk?si=hsB78j1BixZXBplY Bobby Krause, director of the BeStill Foundation Listen to the Podcast: The podcast of this program will be available Monday, Feb. 23, 2026, after broadcast on Feb. 21.

Show 1461: How Patients Are Using Technology to Heal Healthcare

Medicine has changed enormously over the last several decades. As with other parts of society, digital technology has disrupted previous practices. Clinicians can now care for patients at home, monitoring them with sophisticated sensors for oxygen saturation, heart rhythm, blood pressure and much more. Even more significant, patients now have greater access to medical knowledge as well as to the state of their own bodies, measured through wearable tools such as smart watches or continuous glucose monitors. With the internet, they can connect with patient groups that offer valuable information as well as emotional support. Find out how patients are using technology to heal healthcare. At The People’s Pharmacy, we strive to bring you up to date, rigorously researched insights and conversations about health, medicine, wellness and health policies and health systems. While these conversations intend to offer insight and perspective, the content is provided solely for informational and educational purposes. Please consult your healthcare provider before making any changes to your medical care or treatment.

How Technology Is Transforming Healthcare: When we spoke with Dr. Marschall Runge, we reminisced about the changes in medical care that have taken place since the time of his grandfather, a general practitioner. There is quite a contrast. While his grandfather made house calls, few doctors today would do so. However, some very modern medical centers now offer patients the option to recover at home from a major procedure. Dr. Runge describes his personal experience with at-home recovery following hip replacement surgery. The clinical staff was able to keep close tabs on his progress with the help of a variety of monitors, and a nurse was available to answer questions or provide advice until he was back on his feet. There are distinct advantages to the patient to be able to recover at home; among other things, he could sleep much better in his own bed. What other digital technology will healthcare employ? One possibility is using AI conversational agents to assist with differential diagnosis. Some devices can detect depression based on a patient’s speech. Others can pick up heart rate variability, an important parameter of heart health. Dr. Runge does not expect that robots will replace doctors. They could be very helpful in certain situations, though. How Patients Are Using Technology: We turn next to Susannah Fox, author of Rebel Health. She has been studying how patients are using technology to improve their health for decades. We first met Susannah through our mutual friend, Dr. Tom Ferguson. He was a staunch advocate for self-care and excited about the prospects for the internet. (His white paper, “e-Patients: How they can help us heal health care” is a classic. Look for it at the website of the Society for Participatory Medicine.) Not only do patients everywhere now have access to PubMed (the National Library of Congress), they can also connect with each other. Peer-to-peer advice and care is a topic Susannah knows well. In some cases, patients have conducted research that is focused on the questions crucial to their lives; these are not always the same things that researchers want to study. One shining example of patient-initiated research is a paper in Nature on long COVID by the Patient-Led Research Collaborative (Nature Reviews Microbiology, April 17, 2023; initial publication Jan. 13, 2023).  This paper has been downloaded 2 million times, illustrating the value of patient-led research. In addition to this outstanding example, some journals have adopted a policy of disclosing patient input into the research. Although very few studies report patient input, setting the expectation that they might make valuable contributions could help shape the perception of who ought to be involved in developing research protocols. Patients Using Technology to Access Medical Knowledge: PubMed is an impressive collection of published medical information because it is an online index of important research publications. Some of the journal articles could be difficult for patients to understand, however, as researchers are writing for other scientists and may often use specialized or complicated language. Now people are using LLMs like ChatGPT or Claude to summarize the articles in language they can understand. Indeed, these AI agents can translate articles into a different language if necessary for comprehension. With this technology, patients are better able to determine if their diagnosis makes sense and to search for potential interventions that might be useful in their specific case. Imbalances of Power and Attention: Despite these changes, there are still many medical systems that resist potential input from patients. Power is not evenly distributed, and Susannah Fox has found that many people are furious about it. We asked her to describe the schematic from Rebel Health that epitomizes where most attention is needed. It has two axes, one running from visible to invisible and the other from needs not met to needs met. A lot of medical care is devoted to the upper right quadrant–visible needs that are being met. The lower left quadrant, where the needs seem invisible and are not being met, is where patient frustration comes to a head. Rare diseases often fall into this category. Researchers and physicians need to know about patients’ lived experiences so that invisible needs not being met can be addressed. Using Technology to Repurpose Old Drugs: One of the ways in which AI is contributing to important changes in medical care is the search for medicines that can treat inadequately treated diseases. Susannah Fox praised the efforts of Dr. David Fajgenbaum, whose EveryCure organization is using AI to uncover how old drugs can be used to treat cancers, rare diseases, immunologic disorders and other problems that don’t yet have effective standards of care. Other patients who are showing the way to using AI for improving patient experience and patient health are Dave deBronkart (epatient Dave) and Hugo Campos. They have found that using an agent like ChatGPT in a dialog can help them move forward a lot more quickly in solving patient problems. Online Prescribing and Dispensing: Around the turn of the 21st century, Joe and Dr. Tom Ferguson had a heated ongoing disagreement about the concept of online prescribing. Tom was enthusiastic and Joe was skeptical, to say the least. Susannah Fox weighs in on this argument supporting Tom’s side at this point. With wearables like smart watches or continuous glucose monitors to track important markers of health, we see some patients using technology to follow up on how well their prescriptions are working, regardless of whether they were prescribed in the office or online. We also asked Susannah to provide advice for how we can successfully advocate for our own health. Her most important nugget: ask good questions! Clinicians appreciate good questions that help them re-think the patient’s situation or explain it more clearly. This Week’s Guests: Marschall S.

Show 1363: Defeating Seasonal Affective Disorder (Archive)

This week, we interview the doctor who first identified seasonal affective disorder (back in 1984!) and went on to develop treatments. You may want to listen to it through your local public radio station or get the live stream at 7 am EDT on your computer or smart phone (wunc.org). Here is a link so you can find which stations carry our broadcast. One of the most effective treatments for SAD and the similar but less severe winter blues is bright light therapy. Not all sufferers respond to light therapy alone, however. Dr. Rosenthal describes the additional approaches that improve people’s response. If you can’t listen to the broadcast, you may wish to hear the podcast later.

What Is Seasonal Affective Disorder? By now, many people are aware that some individuals have a hard time with short days and long nights. Their appetites and sleep patterns may change, and they may retreat from social activities because they can’t get energized. They have trouble concentrating and may become irritable. It’s as if they get depressed every year at the same time, on cue. Psychiatrists estimate that about 5 percent of the population experiences seasonal affective disorder, or SAD. That could be as many as 10 million Americans. At times, physicians may prescribe antidepressants, but usually the treatment that works best for SAD is light. Evidence suggests that the lack of sunlight, especially when someone feels stressed, is a prime trigger for seasonal affective disorder. Is SAD Linked to Latitude? The further from the equator you get, the more pronounced are seasonal differences in daylight. Think of a place above the Arctic Circle, for example, like Tromsø, Norway. In the summertime, they celebrate the midnight sun. In the winter, however, people in Tromsø see very little daylight. Unless they are uncommonly resilient, they could be susceptible to SAD. Light for Seasonal Affective Disorder: The principal treatment for SAD is light therapy, usually utilizing a light box. This must be a minimum of one foot square and supply at least 10,000 lux. That is the equivalent of being outside on a cloudy day. Generally, the prescription is for 20 to 30 minutes of exposure every morning. People who would rather not use a light box might be able to spend that time outdoors under the dome of the sky. A roof, awning or umbrella would undermine the treatment. Approximately 30 to 40 percent of people with seasonal affective disorder do not respond completely to light therapy. They need additional help beyond light exposure alone. Exercise has been shown to benefit them, especially if it is conducted outside. Cognitive behavior therapy is also extremely helpful, as is meditation. Lastly, people with SAD may want to pull back from their usual social activities. If they can maintain their social connections, this is very therapeutic in the effort to defeat seasonal affective disorder. The Autumn Checklist for Defeating Seasonal Affective Disorder: Those who know that they often experience SAD should get ready before winter. Dr. Rosenthal recommends addressing the following questions: 1. Have I purchased a light box for the winter? 2. Do I have at least one bright, inviting room in my home? 3. Have I made plans for at least one winter vacation in the sun? 4. Should I check in with my doctor since I am entering my season of risk? 5. Have I notified close family members and friends that I may need extra support? 6. Do I have a physical fitness program in place? (It’s easier to keep exercising than to start.) 7. Could I reframe my attitude and look at winter as a challenge instead of an affront? 8. How can I find beauty in the colorful season of autumn, here and now? This Week’s Guest: Norman E. Rosenthal, MD is a psychiatrist and scientist who first described SAD in 1984 and pioneered light therapy as a treatment. Dr. Rosenthal is currently Clinical Professor of Psychiatry at Georgetown University School of Medicine.

Show 1460: Calming Chronic Inflammation Without Medication

Inflammation is a double-edged sword. When you have a sudden injury or infection, your body responds by calling immune cells to the site of the problem. It may become red, swollen and painful, but all that is supposed to be part of the healing process. What happens with chronic inflammation is more insidious. Many serious diseases, such as diabetes, depression or heart disease, feed off chronic inflammation. Anti-inflammatory drugs can control the problem temporarily, but they have drawbacks if they must be used continuously. How can we go about calming chronic inflammation without medication? At The People’s Pharmacy, we strive to bring you up‑to‑date, rigorously researched insights and conversations about health, medicine, wellness and health policies and health systems. While these conversations intend to offer insight and perspective, the content is provided solely for informational and educational purposes.

How Inflammation Works: One of the hallmarks of modern life is the impact of stress on the digestive tract. Excess weight, unrelenting stress and environmental toxins can all contribute to an immune system that goes into overdrive. Sometimes the consequence will be an imbalance in the microbiota, with the result that the tight junctions of the gut are disrupted. That can lead to “leaky gut,” more respectably termed “intestinal permeability.” When pathogens or toxins that should be confined to the gastrointestinal tract start circulating elsewhere, the immune system reacts. If the process continues, the consequence is chronic inflammation. Are there natural approaches to calming chronic inflammation? Calming Chronic Inflammation: When we want to help our immune system so that it doesn’t have to be hypervigilant all the time, we should start with our diet. If dysbiosis contributes to leaky gut and inflammation, the best approach might be to feed our gut microbes what they need. In most cases, that means increasing our fiber. Gut microbes thrive on fiber, and most Americans don’t get close to eating enough. Another important aspect, of course, is to avoid foods that might cause trouble. According to Dr. Low Dog, fructose degrades tight junctions in the intestines and could contribute to intestinal permeability and inflammation. To reduce fructose, we just need to cut back on sweets Finding Fiber in our Food: Where can we find fiber in our diet? Starting with breakfast, a lot of folks enjoy cold cereal, pancakes or pastries. There’s not much fiber in any of those, unless you’ve chosen bran cereal. But even a choice as simple as eating an apple with the skin on can provide a good amount of fiber. Do you like salmon for breakfast? That’s a very anti-inflammatory choice. One worrisome development is the spread of microplastics throughout our diet. As a result, most of us have microplastics in our bodies. Some of the compounds in these little particles of plastic are endocrine disruptors that contribute to inflammation. Maintaining Healthy Barriers: The colon is not the only part of the digestive tract that provides an important barrier. The mouth is also susceptible. Brushing, flossing, dental care and a low-sugar diet are important steps to protecting our bodies against chronic inflammation. Periodontal disease contributes in a major way. To maintain good tight junctions, we need to eat about 20 grams of insoluble fiber and 8 grams of soluble fiber daily. Beans and vegetables are great sources of both. Nuts and seeds like sunflower seeds or walnuts are also good sources. So are whole grains. And if we have any trouble reaching our fiber goals with diet, there is nothing wrong with adding a daily dose of psyllium, which is mostly soluble fiber. It lowers cholesterol and can reduce the risk of diabetes as well as promote regularity. Herbs to Ease Inflammation: In addition to paying attention to a high-fiber anti-inflammatory diet, we can benefit by using certain herbs or spices to calm chronic inflammation. Green tea, garlic, onions, hot peppers and other flavorings all have anti-inflammatory power. Turmeric, the yellow spice in curry, is a potent anti-inflammatory. To get the best benefit from adding turmeric to food, it should be used to spice a meal with some fat in it. Black pepper as part of the spice profile also helps with the absorption of compounds from turmeric. Dr. Low Dog cautions us all to vet our turmeric carefully, though. Some brands are high in lead. She suggests that Simply Organic and McCormick are both brands that were relatively free of lead when tested by ConsumerLab.com or Consumer Reports. One supplement that may be unfamiliar to most listeners is nattokinase. It is derived from natto, a fermented soybean dish that is very popular in Japan. People who are taking anticoagulants should probably avoid nattokinase, even though it has anti-inflammatory activity. It could interact with anticoagulants and increase the danger of bleeding. We would add that precaution should also hold for curcumin supplements derived from turmeric. They should not be taken by anyone on an anticoagulant. Other Natural Approaches to Calming Chronic Inflammation: When we asked Dr. Low Dog about her favorite way to calm chronic inflammation, she mentioned walking in nature. High cortisol levels drive chronic inflammation, but green spaces reduce stress and help bring cortisol down. Other marvelous approaches include seeking out ways to embrace contentment and joy and humor. For some people, that will mean meditation. For others, it will mean hanging out with good friends or going for a run. Nourishing our mental and spiritual health with art and poetry help connect us with meaning and purpose in our lives.

Show 1459: Food Is Medicine: Should Your Doctor Be Prescribing Produce?

One of the most basic pillars of health is good nutrition. A range of eating patterns might all be considered balanced diets, but in general people do better when they eat less processed foods and more whole foods. Vegetables and fruits play a starring role in at least two diets that have been studied extensively, the DASH diet and the Mediterranean diet. Americans might be healthier if we followed these eating plans, but fresh veggies can be pricey. If your doctor were prescribing produce, would your insurance plan cover it? Might this make healthful eating more of a practical possibility? At The People’s Pharmacy, we strive to bring you up to date, rigorously researched insights and conversations about health, medicine, wellness and health policies and health systems. While these conversations intend to offer insight and perspective, the content is provided solely for informational and educational purposes.

Food Is Medicine: Increasingly, healthcare providers are recognizing the critical role of diet in the development of chronic disease. An entire movement is organizing around the concept of Food Is Medicine, both for prevention and for treatment of conditions like diabetes, obesity and heart failure. Scientists have shown that diet makes a difference. Studies have confirmed what many of our grandparents or great-grandparents intuited. On the other hand, translating that knowledge into action that benefits patients has been difficult. One important barrier is the cost of fresh fruits and vegetables. Doctors Prescribing Produce: People could get healthful food in a variety of ways. Past generations often had gardens and grew much of their own produce. That’s not always practical in urban settings or for families with multiple jobs struggling to make ends meet. Our guests today have tested two ways to get fresh food into people’s hands. One is a debit card that can be used to buy any WIC-approved food at more than 66,000 retail outlets across the country. WIC is the USDA supplemental nutrition program for Women, Infants and Children. WIC-approved foods include fresh fruits and vegetables with no added sugar or salt. In this model, the healthcare provider arranges for certain patients to get access to this debit card, providing $40 worth of purchasing power for healthy foods each month. They are essentially prescribing produce. The idea is to use a business model that supports good food and saves the health system money. This is termed a healthy food subsidy. The other approach is a food box. This includes vegetables and fruits, and possibly other foods, that providers decide the patients should get. In some initiatives, the person or agency deciding what goes in the food box might also take into account what is available from local farmers. The box may be distributed weekly, every two weeks or every month, but the individual who is going to be eating the food does not choose what is in it. How Does a Healthy Food Subsidy Compare to Food Boxes When Providers Are Prescribing Produce? When people don’t know if they will be able to pay for the groceries they need, they are said to be “food insecure.” This complicates a range of chronic conditions, making diabetes more challenging, for example. People with food insecurity have a harder time keeping their blood pressure under control. Our guests collaborated with other colleagues on a recent comparing the food box approach to the healthy food subsidy among North Carolina resident with high blood pressure and food insecurity (JAMA Internal Medicine, Dec. 1, 2025). The study enrolled 458 individuals. Everyone in the study had a provider prescribing produce. Half the volunteers got the food subsidy debit card and half were provided with food boxes. Those getting the food subsidy had moderately lower blood pressure after six months compared to those getting food boxes. Their blood pressure was also lower after a year and a half. Food insecurity decreased in both groups over time. Tackling Food Insecurity: One of the outcomes of food insecurity is that people are more likely to need emergency department services. This costs the insurance company dearly. If improving food security and diet quality could reduce ED visits, insurers might become quite interested in the food subsidy approach. This is currently being tested for participants with heart failure. Special Populations Who Might Need Providers Prescribing Produce: During this conversation, we expressed concern about vulnerable populations that might suffer especially from cuts in government spending. We asked about school lunches and we learned about pilot programs focusing on expectant mothers. Children in foster care are especially vulnerable; a food subsidy program taking a Food Is Medicine approach could be helpful for them. This Week’s Guests: Seth A.
