Apomorphine has a more than 20-year history as a therapeutic adjunct in the management of idiopathic Parkinson disease. And yet, no randomized, placebo-controlled clinical trial to show for it. As of July 2018, now there is. In this week's episode of BrainWaves, Dr. Siegler discusses the relevance, strengths, and weaknesses of the TOLEDO trial.

Progressive weakness can be terrifying for patients. And even more terrifying for clinicians can be the vast number of potential causes to consider. Among them are disorders of muscle inflammation. In this week's episode of the Quanta series, Dr. Megha Dhamne reviews the clinically relevant antibodies and associated phenotypes we see in patients with autoimmune myositis.

Quantum (noun, pl. quanta): The amount of neurotransmitter stored within a single vesicle of a neuron. It is quantitatively the smallest amount of information that can be transmitted between nerves in the human body. We have hijacked this concept to describe the smallest amount of information we can share with you on a neurology podcast. In this series, which we have called Quanta, we'll be discussing the most fundamental neurologic principles so that our main episodes won't have to. Enjoy!

In 2016, the management of patent foramen ovale was “open” for discussion. Now (2017), consider the case closed. Recent data indicate patent foramen ovales should be closed in certain patients with cryptogenic strokes. But some questions remain unanswered. This week's episode is a follow-up discussion on this frequent topic that troubles stroke units.

2019 was a big year. The year of the Mueller report. The American college admissions scandals. Brexit. But it was also the year the US Women's team won the World Cup and lobbied for the equal pay of women and men in sports. It was the year of NMO, in which several pivotal trials showed the benefit of disease-modulating therapy in this condition. The year Will Smith played Genie in Aladdin.
2019 was a great year. And as we wrap up 2019, this week's episode includes some of the highlights. Enjoy!

The FDA label for ACTEMRA® (tocilizumab)--the first medication approved for use in giant cell arteritis in 2017--is 40 pages long. Of the information provided in this document, which includes important dosing information, dose adjustments based on leukocyte count, clinical trial and epidemiologic data, there is a box of text on the first page of the insert. "WARNING: RISK OF SERIOUS INFECTIONS," it reads.
What do you make of this warning? And with such a clear and broad-sweeping statement stamped on the medication, how do you mitigate the medico-legal risk of using this drug?
This week on the program we launch into a two-part series focused on some of the events that follow major clinical trials. In part 1, we cover the three major classifications of FDA alerts for medical treatments using two examples from the neurologic pharmacopoeia. In part 2, we emphasize the importance of post-publication peer review. And both are equally instrumental in our medical decision-making.

Peer review prior to publication of medical data dates back to the 9th century CE but has only really gained steam in the past 70 or 80 years. Ideally, peer review would serve as an initial filter for data that enter a permanent public scientific record. But peer review is not without flaws. In the second installment of the BrainWaves segment, “It’s not over yet…,” we discuss publication as a potential source of bias and highlight the reasons why it should not be the final step of the peer review process.

Since January 1, 2019, there have been nearly 900 confirmed measles cases across 24 states in the United States. This is 10 times greater than the number of cases in the US 3 years ago, and it is the largest outbreak the US has seen since 1994. The month of May also marks the first reported case of measles in the state of Pennsylvania, where BrainWaves is produced. So this week on the program, Jim Siegler speaks with Dr. Erika Mejia (pediatrician) about the medical and sociopolitical triggers for this outbreak, the misconceptions of the measles-mumps-rubella vaccine, and finally, what you can do to keep measles from "going viral."*

Of the "reversible" causes of dementia, normal pressure hydrocephalus may be the most controversial. But there is something to be said about how surgical intervention alters the physiology of patients who present with gait impairment, ventriculomegaly, and normal CSF pressure. This week on the show, we discuss the clinical features and the controversy behind this diagnosis.

A patient comes into the emergency department. They've got a headache. You get some basic labs, a chest x-ray, and a CT scan. And then you get a drug screen. But does this information even help you? And could it hurt the patient?
This week on the BrainWaves podcast, Dr. Emily Rosenthal shares her experience with Dr. Kelley Humbert on the ethics of toxicology "screening" and how she manages patients with a substance use disorder.

As the name suggests, "evidence-based medicine" is dependent on published evidence to support our clinical practice and medical decision-making. Implicit in this is the notion that all published evidence reflects the truth that underlies the biology, pathophysiology, and pharmacology of our health.
This is not the case.
Clinical research and published findings can be extremely limited, and what you read in Lancet and NEJM should be interpreted with caution. In this week's episode of the "I wonder" series, where Jim Siegler speaks with Ali Hamedani on various topics in medicine and neurology, the speakers review the major biases inherent to the practice and interpretation of clinical research.

As a pupil of neurology and medicine, I feel like it is my responsibility to cover this topic at least once on the podcast. This topic came to me in a vision. But not one of phosphenes or impaired stereopsis--both of which we'll cover today. This week, we're discussing inflammation of the optic nerve, from the historical aspects to current concepts. And while you're listening, there's no need to lash out at my puns. You can stop rolling your eyes now.

When it comes to stroke, treatment is dependent on the stroke mechanism. But most patients wind up on aspirin anyway. Or Plavix (clopidogrel). And sometimes both. The question this week is, Why? I hope you're hungry for some fruit because we're comparing a bunch of apples to oranges in this episode of the BrainWaves podcast.

The most common primary brain tumor that occurs in adults, glioblastoma multiforme, comes with a life expectancy shorter than practically every other form of cancer. But thanks to novel treatment strategies, advanced neuroimaging, and biomarker research, we are learning more and more about how to improve the survival and the quality of life of patients who suffer from this terrible illness.

Spinal cord injury can be a devastating problem for patients. There is often significant weakness and loss of sensation and coordination, and some patients may never walk again. Almost everyone knows this. But what about the other spinal cord functions that we don't often talk about? In this week's episode, we review how the spinal cord controls bladder function and why it's important to know what happens when this circuitry is interrupted.

Not all that shakes are seizures. Last week, we talked about what it's like to have epilepsy. This week, I am joined by Dr. Taneeta "Mindy" Ganguly to discuss what it's like NOT to have epilepsy--meaning to have non-epileptic seizures. But sometimes, you can have both. And this is where it gets tricky for the neurologist.

As I'm sitting in a coffee shop in upstate New York this holiday season, procrastinating on the various papers that need writing, bills that need paying, and Christmas cards that need writing, I can't help but feel comforted by the warm relief of a cup of coffee. The rich aroma and jolting heat, which come with the promise of productivity. There's nothing like it. So before resigning to my post-holiday to-do list, I thought I would start the day off re-mastering a prior show we put out in 2017 on the neuroscience behind your morning mocha. Enjoy!

Yes, we have harnessed the power of paralysis. Botulinum toxin, which is produced by a lethal bacterium, Clostridium botulinum, has been bottled and sold to neurologists for decades. And you know this because you've seen people who received Botox to relax their facial muscles. In this week's installment, Dr. Anh-Thu Vu discusses how neurologists utilize this neurotoxic agent.

I can't imagine a better way to celebrate our FIFTIETH episode than to discuss my favorite subject: large vessel disease. Although we only cover one aspect of this stroke mechanism--atherosclerosis--and technically many of these trials may be somewhat outdated, the matter discussed in this episode remains the most up-to-date in the field.

There is nothing mysterious about the chemistry of the cerebrospinal fluid. Cells. Protein. Glucose. But the interplay of these unique components can give you incredible insight into the state of the central nervous system. This week, we revisit a prior episode where Dr. Mike Rubenstein reviews his approach to interpreting CSF results. And then we have an update at the end regarding recent advances in CSF analysis.

Idiopathic intracranial hypertension, also known as the pseudotumor cerebri syndrome, is characterized by elevated intracranial pressure with clinical features of headaches, vision impairment, and occasionally cranial nerve palsies in the absence of a structural lesion on neuroimaging. But that doesn't mean the neuroimaging has to be normal. See what Dr. Anita Kohli has to say about the radiographic correlates of idiopathic intracranial hypertension, their relevance, and their prognostic utility in this week's episode.

In 1959, Adams and colleagues described a few patients who developed a rapid flaccid quadriparesis following fluid resuscitation for malnutrition and chronic alcoholism. Twenty years later, we learned that this occurs as a consequence of rapid correction of hyponatremia. But this isn't the only cause of the osmotic demyelination syndrome. Hear Dr. Joshua VanDerWerf discuss the history and clinical relevance of this unusual critical care scenario.

The request for a consult is like calling in a favor. You shouldn't actually expect the consultant to do it; you should be polite and helpful in all the ways your grandmother expects you to behave. At least, that's the courtesy I've seen from really spectacular providers. In this week's episode, we review the proper etiquette for calling a consult, and you'll also hear some pearls on the workup for altered mental status.

For those of you who've witnessed it, giving levodopa to a patient with idiopathic Parkinson disease is almost a miracle to watch. Unlike practically every other condition afflicting the nervous system, the unmistakable unrest of Parkinson disease essentially surrenders to this tiny tablet. But what did we use before levodopa? In this week's episode of BrainWaves, we recount the history (and serendipity) behind the development of this miracle drug.

Idiopathic Parkinson disease is the second most common cause of neurodegenerative disease following Alzheimer disease. The risk of Parkinson disease increases to nearly 1 in 100 in the elderly, and although we have been pharmacologically treating this disorder since the early nineteenth century, we have no cure and no definite therapy to delay disease progression. In this episode of BrainWaves, Dr. David Coughlin illustrates how some of these therapies have evolved and which classes of medications to choose when managing a patient's symptoms--from tremor to dystonia.

It seems like a new antibody in autoimmune central nervous system disorders is being discovered every day. Well, maybe not that frequently. But autoimmune encephalitis may now be as common as infectious encephalitis. In this week's program, we revisit an episode from 2016 where Dr. Ramani Balu (neurocritical care) shares his experience in evaluating and managing patients with these conditions.

Myasthenia gravis is a disorder characterized by proximal weakness, ptosis, and antibody formation against proteins at the neuromuscular junction. Most commonly, the protein targeted by antibodies is the nicotinic acetylcholine receptor. However, research in the last 2 decades has identified a number of other antibody targets, which we have reviewed here in this BrainWaves brief.

Although physicians use medications to treat headaches, the mind can become tolerant. In fact, many otherwise helpful medications may even aggravate a pre-existing headache syndrome.

Long-term antithrombotic treatment of embolic stroke sounds like a tricky field to navigate. Aspirin is the drug of choice in the acute setting for most patients, but when cardioembolic stroke is suspected, aspirin is inferior to anticoagulation for preventing recurrent stroke. In the age of novel oral anticoagulants, why choose warfarin and risk drug interactions, dietary restrictions, and bleeding risk? In this episode, we discuss the pros and cons of each of the major NOACs for secondary stroke prevention. Enjoy!

The Landry-Guillain-Barre-Strohl Syndrome, aka Guillain-Barre Syndrome, is classically thought of as a painless ascending weakness with areflexia that typically follows an infectious prodrome. But there are a dozen variants with unusual clinical presentations, from back pain to pandysautonomia. And sometimes Guillain-Barre Syndrome follows a vaccination rather than a viral infection. In this BrainWaves episode, we discuss these and other unique facts regarding the history, clinical manifestations, and treatment of this polyneuropathy.

This week, we are taking a break from educational neurology and will be stressing the importance of collaboration between patients and physicians. Physicians are critical to healthcare because of their expertise and experience, but medical management is a team sport. It is equally important to incorporate the patient's needs and opinions into the equation. But this leaves us with the concept of "therapeutic privilege," specifically how much does the physician need to tell the patient about his or her own health? In this episode, Jim Siegler steps into the shoes of one of his good friends who has faced a recent cancer diagnosis.

There's more to epilepsy than AED titration. (Shocking, I know.) Especially in women, management is undeniably complex. For example, the same enzymatic machinery used to metabolize AEDs is also used to break down estrogen-containing oral contraceptives--an interaction that could literally open a Pandora's box of complications. These and other issues affecting the management of women with epilepsy are addressed by Dr. Danielle Becker in this week's BrainWaves podcast.

With the ongoing opioid crisis, not only those using opiates are affected. There has been an exponential rise in the incidence of neonatal abstinence syndrome--the multiorgan dysfunction experienced by newborns of mothers who are using opioid products and other substances. This week, we discuss the manifestations and ramifications of this disease, with a short commentary on the implications of this global epidemic.

Perfusion imaging employs concepts that date back to the early 1830s, and it leverages hardware and software that emerged around the same time as multidetector helical CT scans. But it has only become popular in recent years for thrombectomy decision-making. If I'm being honest, I often never use it for this purpose. So what other purposes might it serve? And how does it work? This week, we review the fundamental concepts of perfusion CT, its utility in stroke care, and how it might prove useful for other neurologic conditions as well.

As my wife and I are raising our 9-month-old daughter, and she is eating more solid food, I can't help but think about how important it is for her to keep an open mind to new food groups. But being open-minded is not just a lesson for toddlers. I emphasize it every day on rounds when seeing patients for a "stroke consult" or a consult for "ICU delirium." If you reduce yourself to the same anchoring biases that you've grown accustomed to, you'll never entertain the possibility of other important and treatable conditions. Or tasty foods. This week on the BrainWaves Podcast, Dr. Brian Jankowitz (Cooper University Hospital Vascular Neurosurgeon) joins Jim in a discussion about a rare but treatable cause of myelopathy. A condition you won't want to miss.

Can you hear that too? You can't? Well, that doesn't mean I'm having auditory hallucinations. It could just be tinnitus, which describes the irritating sound of ringing, buzzing, clicking, or hissing that affects 10% to 20% of the world's population. But is this a ringing in the ears or a ringing in the brain?

Nobody is getting any younger, which is too bad. Muscle cramping...fatigue...stiffness... you'll be dealing with it more and more. “It's probably nothing,” you tell yourself. But what if it's not? Every once in a while, you might come across a case of myotonia. And you won't want to miss it. This week on BrainWaves, Dr. Noah Levinson provides a brief overview of myotonia and the conditions that are associated with it.

Before it was called epilepsy, it was a falling sickness. A disturbance of consciousness summoned by magic or demonic possession. Although it is less of a mystery today, the sacred disease is one neurologic condition that continues to pique our curiosity. Join us as we recount the fascinating history of this mystical malady.

The common teaching is that restricted diffusion on MRI indicates stroke—acute cerebral infarction--when, more specifically, the changes on DWI and ADC indicate impairment in the random movement of water molecules in a given tissue. With slower movement, as in energy-depleted tissues with failing ATP-dependent sodium/potassium channels, high cellularity, or a highly viscous extracellular space, there is restricted diffusion (of water) and a corresponding bright signal on DWI. These and other considerations are the focus of this week's episode of BrainWaves.

Immune checkpoint inhibitors have revolutionized cancer treatment. Unlike chemotherapy, which essentially includes cellular toxins that can cause widespread and unnecessary tissue damage, checkpoint inhibitors are used to train the body’s natural immune system to fight off cancer. And while they are extraordinarily effective options for patients with malignant disease, they are not without risk. Every day, we are learning more and more about the autoimmune side effects of these novel therapies. This week on the BrainWaves Podcast, Dr. Justine Cohen (University of Pennsylvania) shares her experience managing patients with checkpoint inhibitor neurotoxicity.
Produced by James E Siegler and Justine Cohen. Music courtesy of Jon Watts, Kai Engel, and Kevin McLeod--as well as a cameo appearance by the Checkpoints.

Locked-in syndrome is a rare clinical consequence following many types of neurologic injury. In general, the locked-in patient is fully paralyzed, with perhaps minimal function of the fingers, eyes, or mouth. What's more, gross motor dysfunction is enormously disproportional to the cognitive function of the individual. The locked-in patient is conscious and completely aware of their surroundings. They can often hear, see, smell, and feel just as any other person would. But because of their profound physical disability, they have a very limited means of communicating even the simplest thoughts. "I feel hot." "My head hurts." "My cheek itches."
It may surprise you that the patient's perspective of their condition is wholly different from how the healthcare provider or caregiver imagines it to be. This week on the program, Dr. Lauren Elman (Pennsylvania Medical Center ALS Multi-disiplinary Clinic) reviews this discrepancy. Dr. Elman also shares her experience managing this inevitable consequence of amyotrophic lateral sclerosis when all life-sustaining measures are desired.

Unfortunately, stroke is all too common. Nearly 1 million new strokes are diagnosed in the United States each year. And this means that complications of stroke--even if rare--may also be common. One such complication is hemorrhagic transformation. This week, Dr. Ava Liberman reviews a clinical case of hemorrhage following ischemic stroke.

Webster defines “idiopathic” as “arising spontaneously or from an obscure or unknown cause.” By definition, this means idiopathic intracranial hypertension has no proximate cause. But that’s not exactly true. This week on the podcast, we explore the evidence behind the theory that transverse sinus stenosis may contribute to this condition. Disclaimer: No chicken or eggs were harmed in the making of this episode.

The sole FDA-approved indication for clobazam is as a therapeutic adjunct in Lennox-Gastaut syndrome. But as more and more clinicians publish their experience with the off-label success of certain therapies, we may see new indications for this and other pharmacologic agents in the treatment of neurologic disease.

In 2012, more than 13,000 Americans were inadvertently exposed to contaminated medical equipment, resulting in one of the largest fungal outbreaks in United States history. Despite rapid mobilization by the CDC and FDA, 751 patients died from complications of fungal brain infections. But this is more the exception than the rule when it comes to fungal infections of the central nervous system. This week on the BrainWaves podcast, we review the common (and uncommon) clinical, radiographic, and diagnostic features of fungal brain disease. Enjoy!

Even as a medical professional, it can throw you off to be out in public and find someone acutely unresponsive. It's not like being in the hospital. There are no crash carts, no nursing support, and no diagnostic tests--just you and whatever you have around you. So, what can you do? This week, Dr. Ramani Balu discusses the first 5 minutes of this assessment, with a little twist. You're stuck on an airplane.

I shouldn't have to tell you that traumatic brain injury is a major cause of morbidity and mortality. I shouldn't have to. But I will. And it is. In severe cases of head injury, there can be delayed and irreversible deterioration in the nervous system for which there is no treatment, and the prognosis is grim. This week on the program, Dr. Monisha Kumar (University of Pennsylvania) discusses the worst of the worst of these scenarios, what to look out for, and expert recommendations on what to do when it happens.

Machado-Joseph disease, or spinocerebellar ataxia type 3, is one of the few eponyms in medicine whereby the disease is named after the patient and not the physician who originally described it. But someone else's name is missing from the eponym: Thomas. And the alternative title for the condition, "spinocerebellar ataxia," also happens to be a bit of a misnomer. In this week's installment of BrainWaves, we review the history and clinical manifestations of this movement disorder.

A 50-year-old gentleman presents with severe headaches and speech disturbance. The MRI shows acute strokes and multifocal vascular irregularities. Is it reversible cerebral vasoconstriction syndrome or primary angiitis of the central nervous system? Or is it something else entirely?
RCVS and PACNS almost always pose a challenge--even to the most astute neurologist. But, because they are treated entirely differently and their clinical trajectories depend on these treatments, it is worth knowing how experts distinguish the two. This week on the BrainWaves podcast, Dr. Jesse Thon joins Jim Siegler in a discussion about the clinical and radiographic features of these two conditions and shares his experience in managing these patients.

For patients who survive cardiopulmonary arrest but do not wake up, neurologists are called to the bedside to prognosticate. And the question of “How much will this patient recover?” is not unlike “What is the benefit of aggressive therapy to await possible recovery?” In that way, you might consider neurologists to be the actuaries of hospital medicine. In this week's program, we review the clinical and diagnostic data that neurologists incorporate into their model for outcome prediction following anoxic brain injury.

Although he may never have attended university, Leonardo da Vinci (1452-1519) was a true scholar of the Renaissance. His contributions to civil and mechanical engineering, the creative arts, and natural philosophy are nothing short of extraordinary. Less well popularized--although of equal importance--were his accomplishments in the field of anatomy. This week on the BrainWaves Podcast, we delve into his discoveries, his methodology, his handedness, and the message he has left us.

Lesion localization is a critical skill for any neurologist. The so-called "cortical signs" are symptoms or examination findings, which are often associated with cortical neuron injury--aphasia, neglect, gaze preference. But they are also seen after injury to subcortical structures, including white matter tracts, the thalamus, and basal ganglia. In this week's installment of the BrainWaves podcast, we'll attempt to localize subcortical lesions based on these major cortical signs.

Generalized weakness is a common complaint. Much of the time, we as neurologists don’t even see these patients in the hospital or the clinic. But more often than not, “generalized” weakness may be the only way a patient describes difficulty brushing their hair or climbing stairs. In these situations, it’s not exactly generalized weakness. It’s something else. This week on BrainWaves, we review the major patterns of weakness that characterize the most common muscle disorders. With a quick review of EMG findings. Enjoy!

They say the eyes are the window to the soul. Well, maybe. They also happen to be the first organ we (perhaps, unknowingly) examine whenever we encounter a patient. This week on the program, we build on the prior episode about anisocoria (featuring Dr. Ali Hamedani, episode 74) and discuss the examination of the pupil, and all that these 3-5 millimeters of tissue can teach us.
Plus, some Dad jokes at the end...

People fall for a lot of reasons when they get older, but that doesn't mean they should see a neurologist. A person can fall because of weakness, back or leg pain, instability, clumsiness, vision impairment, a sensory disturbance, and a myriad of other causes. Some of these are neurological, and these require special attention. In this week's Teaching through Clinical Cases episode, Dr. Sneha Mantri discusses a patient who presented to her clinic with falls due to rigidity and ocular dysmotility.

In the TV show, HOUSE, it's either lupus or its sarcoidosis. Only, it's never sarcoidosis. That's because sarcoidosis is such a heterogeneous condition and can affect practically any age group. In some patients, this idiopathic inflammatory disorder can also involve the nervous system. Also causing a variety of signs and symptoms ranging from mild headache to a proximal myopathy or even a CNS vasculitis. This week on the BrainWaves podcast, Dr. Jesse Thon reflects on the literature and shares his experience managing patients with this troubling condition.

To quote Donald Rumsfeld, “there are things we know we know…. we know there are some things we do not know... But there are also unknown unknowns—the ones we don't know we don't know…it is the latter category that tends to be the difficult ones.”
In neurology, the agnosias are not that dissimilar from Rumsfeld’s 'unknown unknowns.' In this week’s program, we discuss the nosology and nomenclature for the agnosias, the localization, and the importance of recognizing one.
