Plan for Europe's huge new particle collider takes shape

Europe's CERN laboratory revealed more details Monday about its plans for a huge new particle accelerator that would dwarf the Large Hadron Collider (LHC), ramping up efforts to uncover the underlying secrets of the universe.

If approved, the Future Circular Collider (FCC) would start smashing its first particles together around the middle of this century -- and start its highest-energy collisions around 2070.

Running under France and Switzerland, it would be more than triple the length of CERN's LHC, currently the largest and most powerful particle accelerator.

The idea behind both is to send particles spinning around a ring to smash into each at nearly the speed of light, so that the collisions reveal their true nature.

Among other discoveries, the LHC made history in 2012 when it allowed scientists to observe the Higgs boson for the first time.

But the LHC, which cost $5.6 billion and began operating in 2010, is expected to have run its course by around 2040.

The faster and more powerful FCC would allow scientists to continue pushing the envelope. They hope it could confirm the existence of more particles -- the building blocks of matter -- which so far have only been theorised.

Another unfinished job for science is working out exactly what 95 percent of the universe is made of. About 68 percent of the universe is believed to be dark energy while 27 percent is dark matter -- both remain a complete mystery.

Another unknown is why there is so little antimatter in the universe, compared to matter.

CERN hopes that a massive upgrade of humanity's ability to smash particles could shed light on these enigmas and more.

"Our aim is to study the properties of matter at the smallest scale and highest energy," CERN director-general Fabiola Gianotti said as she presented an interim report in Geneva.

The report laid out the first findings of a FCC feasibility study that will be finalised by 2025.

$17 billion first stage

In 2028, CERN's member states, which include the UK and Israel, will decide whether or not to go through with the plan.

If given the green light, construction on the collider would start in 2033.

The project is split into parts.

In 2048, the "electron-positron" collider would start smashing light particles, with the aim of further investigating the Higgs boson and what is called the weak force, one of the four fundamental forces.

The cost of the tunnel, infrastructure and the first stage of the collider would be about 15 billion Swiss Francs ($17 billion), Gianotti said.

The heavy duty hadron collider, which would smash protons together, would only come online in 2070.

Its energy target would be 100 trillion electronvolts -- smashing the LHC's record of 13.6 trillion.

Gianotti said this later collider is the "only machine" that would allow humanity "to make a big jump in studying matter".

After eight years of study, the configuration chosen for the FCC was a new circular tunnel 90.7 kilometres (56.5 miles) long and 5.5 metres (feet) in diameter.

The tunnel, which would connect to the LHC, would pass under the Geneva region and its namesake lake in Switzerland, and loop round to the south near the picturesque French town of Annecy.

Eight technical and scientific sites would be built on the surface.

CERN said it is consulting with the regions along the route and plans to carry out impact studies on how the tunnel would affect the area.

Orlando, Fla - More than two in five U.S. adults suffer from obesity, an epidemic that continues to trend upward. While bariatric surgery is an extremely effective treatment option, a new national survey by Orlando Health reveals common stigmas that may deter those who qualify for surgery from pursuing the treatment they need.

“Treatment plans for obesity are tailored to each individual patient based on things like body mass index and existing medical conditions and may include medication, lifestyle changes, counseling and bariatric surgery,” said Andre Teixeira, MD, medical director and bariatric surgeon at Orlando Health Weight Loss and Bariatric Surgery Institute. “By taking this personalized approach, we are extremely successful in reversing health issues caused by obesity, from diabetes to heart disease. But if someone’s decision is affected by those who think they don’t need surgery or that make them feel like a failure if they have surgery, that greatly diminishes their chances of losing weight and maintaining a healthy lifestyle long term.”

The survey, conducted by Ipsos, found 79% of Americans believe weight loss surgery should only be pursued as a last resort, and 60% agree that bariatric surgery is a shortcut to shedding pounds, something Dr. Teixeira says couldn’t be further from the truth.

“Bariatric surgery is by no means an easy way out. If you have the courage to ask for help and commit to doing the hard work of changing your diet and improving your life, you’re a champion in my book.” Dr. Teixeira said. “Surgery is simply a tool to jumpstart that change. After surgery, it is up to the patient to learn how to eat well, implement exercise into their routine and shift their mindset to maintain their health for the rest of their lives.”

Guidelines by the American Society of Metabolic and Bariatric Surgery (ASMBS) and International Federation for the Surgery of Obesity and Metabolic Disorders (IFSO) were recently updated for the first time since 1991 to expand access to bariatric surgery, which is less invasive and safer than ever, thanks to advancements in laparoscopic and robotic surgery techniques. Yet only 1% of those who are clinically eligible undergo surgical treatment for obesity.

The survey also found that 61% of respondents believe exercise and diet should be enough.

“Because of the stigma around obesity and bariatric surgery, so many of my patients feel defeated if they can’t lose weight on their own,” said Muhammad Ghanem, MD, a bariatric surgeon at Orlando Health Weight Loss and Bariatric Surgery Institute. “But when I tell them obesity is a disease and that many of its causes are outside of their control, you can see their relief. They often even shed a tear because they’ve struggled with their weight all their lives and finally have some validation.”

That was the case for Maritza Cruz Rivera, 64, who lived with pain and fatigue for years and finally hit a breaking point during a routine visit to her primary care physician.

“When they weighed me before my appointment, I looked at the scale and started to cry. There it was: 227,” Cruz Rivera said. “Something triggered in me in that moment to finally do something about my weight and get some help.”

Upon learning that bariatric surgery was a good option for her, she spoke with friends and family. While many supported her decision to undergo surgery, she also heard a lot of misconceptions. She says it’s best to get the facts from your doctor and make a decision based on what is best for your health.

Following surgery, Cruz Rivera changed her relationship with food and began prepping healthy salads and soups that she enjoys. A year later, she is at a healthy weight and is living the life she’s always strived to live, riding her bicycle with her grandchildren, going for long walks in her neighborhood and even doing one of her favorite things: dancing.

“I haven’t been able to dance like this in 20 years. I didn’t go into this to look like Barbie, I just wanted to live a healthy life with my family, and now I can do that,” Cruz Rivera said. “For anyone struggling with obesity who feels depressed or stuck like I did, don't bury yourself in that dark hole. Understand and know that there's always a solution.”

Advisory panel issues field-defining recommendations for investments in particle physics research


Argonne is set to contribute to the realization of the recommendations, which will shape the next decade of discovery in particle physics


Reports and Proceedings

DOE/ARGONNE NATIONAL LABORATORY




Contributions from Argonne will drive innovation in particle physics and shed light on outstanding mysteries in the field.

Yesterday marked the release of a highly anticipated report from the Particle Physics Project Prioritization Panel (P5), unveiling an exciting new roadmap for unlocking the secrets of the cosmos through particle physics.

The report was released by the High Energy Physics Advisory Panel to the High Energy Physics program of the Office of Science of the U.S. Department of Energy (DOE) and the National Science Foundation’s Division of Physics. It outlines particle physicists’ recommendations for research priorities in a field whose projects — such as building new accelerator facilities — can take years or decades, contributions from thousands of scientists and billions of dollars

The 2023 P5 report represents the major activity in the field of particle physics that delivers recommendations to U.S. funding agencies. This year’s report builds on the output of the 2021 Snowmass planning exercise — a process organized by the American Physical Society’s (APS) Division of Particles and Fields that convened particle physicists and cosmologists from around the world to outline research priorities. This membership division constitutes the only independent body in the U.S. that represents particle physics as a whole.

“With our state-of-the-art facilities and community of dedicated scientists, Argonne’s contributions are shaping the global trajectory of high-energy physics.” — Rik Yoshida, Argonne High Energy Physics Division Director

“The P5 report will lay the foundation for a very bright future in the field,” said R. Sekhar Chivukula, 2023 chair of the APS Division of Particles and Fields and a distinguished professor of physics at the University of California, San Diego. ​“There are extraordinarily important scientific questions remaining in particle physics, which the U.S. particle physics community has both the capability and opportunity to help address, within our own facilities and as a member of the global high energy physics community.”

The report includes a range of budget-conscious recommendations for federal investments in research programs, the U.S. technical workforce and the technology and infrastructure needed to realize the next generation of transformative discoveries related to fundamental physics and the origin of the universe. For example, the report recommends continued support for the Deep Underground Neutrino Experiment (DUNE), based out of DOE’s Fermilab in Illinois, for CMB-S4, a network of ground-based telescopes designed to observe the cosmic microwave background (CMB), and for the planned expansion of the South Pole’s neutrino observatory, an international collaboration known as IceCube-Gen2, in a facility operated by the University of Wisconsin–Madison.

Researchers at DOE’s Argonne National Laboratory stand at the forefront of high energy physics and are poised to contribute significantly to the advancement of the field over the next decade. They are exploring the fundamental nature of the universe and pioneering innovative technologies with far-reaching implications. In particular, Argonne’s High Energy Physics (HEP) division leverages the laboratory’s suite of multidisciplinary facilities and equipment — including world-class scientific computing capabilities — to further scientific discovery and advance accelerator technology. For example, Argonne’s contributions to key high energy physics collaborations include the design and fabrication of components for DUNE, the development of cutting-edge detectors for CMB-S4 and more.

“With our state-of-the-art facilities and community of dedicated scientists, Argonne’s contributions are helping to shape the global trajectory of high-energy physics,” said Rik Yoshida, director of Argonne’s HEP division. ​“This report reflects the collective wisdom of the high energy physics community, and we look forward to leveraging our expertise and capabilities here at Argonne to help uncover the mysteries of the universe, drive innovation, inspire future generations of scientists and bolster our nation’s vital role in the future of particle physics.”

“In the P5 exercise, it’s really important that we take this broad look at where the field of particle physics is headed, to deliver a report that amounts to a strategic plan for the U.S. community with a 10-year budgetary timeline and a 20-year context. The panel thought about where the next big discoveries might lie and how we could maximize impact within budget, to support future discoveries and the next generation of researchers and technical workers who will be needed to achieve them,” said Karsten Heeger, P5 panel deputy chair and Eugene Higgins Professor and chair of physics at Yale University.

New knowledge, and new technologies, set the stage for the most recent Snowmass and P5 convenings. ​“The Higgs boson had just been discovered before the previous P5 process, and now our continued study of the particle has greatly informed what we think may lie beyond the standard model of particle physics,” said Hitoshi Murayama, P5 panel chair and the MacAdams Professor of physics at the University of California, Berkeley. ​“Our thinking about what dark matter might be has also changed, forcing the community to look elsewhere — to the cosmos. And in 2015, the discovery of gravitational waves was reported. Accelerator technology is changing too, which has shifted the discussion to the technology R&D needed to build the next-generation particle collider.”

The U.S. participates in several major international scientific collaborations in high energy physics and cosmology, including the European Council for Nuclear Research (CERN), which operates the Large Hadron Collider, where the Higgs boson was discovered in 2012. The P5 report recommends that the U.S. support a significant in-kind contribution to a new international facility, the ​“Higgs factory,” to further our understanding of the

WASHINGTON, D.C.—The High Energy Physics Advisory Panel (HEPAP) to the High Energy Physics program of the Office of Science of the U.S. Department of Energy and the National Science Foundation’s Division of Physics has released a new Particle Physics Project Prioritization Panel (P5) report, which outlines particle physicists’ recommendations for research priorities in the field. The 2023 P5 report was posted online yesterday and was voted on and accepted by HEPAP today.

The 2023 P5 report represents the major activity in the field of particle physics that delivers recommendations to U.S. funding agencies.

“We welcome the P5 report recommendations, which define a strong and balanced U.S. particle physics program based on input from the Snowmass community-wide process,” said Brookhaven National Laboratory Director JoAnne Hewett. “Building on our decades of expertise in high energy physics and facility design and operation, we are eager to actively engage and lead in developing, constructing, and operating the next generation of facilities and experiments to explore the Quantum Universe.”

The report includes a range of budget-conscious recommendations for federal investments in research programs, the U.S. technical workforce, and the technology and infrastructure needed to realize the next generation of transformative discoveries related to fundamental physics and the origin of the universe. For example, the report recommends continued support for the high-luminosity upgrades at the Large Hadron Collider (LHC), based in Europe, for the Deep Underground Neutrino Experiment (DUNE), based out of Fermilab in Illinois, for CMB-S4, a network of ground-based telescopes designed to observe the cosmic microwave background, and for the planned expansion of the South Pole’s neutrino observatory, an international collaboration known as IceCube-Gen2, in a facility operated by the University of Wisconsin–Madison.

It also recommends that the United States study the possibility of hosting the next most-advanced particle collider facility, to reinforce the country’s leading role in international high energy physics for decades to come.

DOE’s Brookhaven National Laboratory contributes to many of the projects highlighted in the P5 report, including these major efforts:

Brookhaven Lab serves as the U.S. host laboratory for the ATLAS experiment, one of four major detectors at the LHC. ATLAS has opened new frontiers of knowledge about elementary particles and their interactions, including the 2012 discovery of the Higgs boson. Brookhaven Lab scientists contributed to that groundbreaking discovery and subsequent studies of Higgs properties, as well as ATLAS project management and experiment operations. They also run a state-of-the-art computing center for storing and sharing ATLAS data with collaborators around the world. Brookhaven physicists, engineers, and technical staff also helped design and build the magnets that steer the LHC’s beams of protons and other ions into collisions—including magnets enabling drastically increased collision rates for future discoveries.

In addition, the Brookhaven team has proposed ideas for and is dedicated to working closely with international and U.S. partners to develop a Higgs factory and its associated detectors. This facility, as recommended in the P5 report, would create copious numbers of Higgs particles and allow detailed, precision studies of their properties—potentially opening the door to discovering discrepancies between theory and experiment that could reveal new physics. The P5 panel also recommends dedicated R&D to explore a suite of promising future projects, including colliders that can reach even higher energies than Higgs factories. Brookhaven scientists are actively engaged in the development of technologies for one such approach—a machine that could collide particles called muons, heavy cousins of electrons.

Brookhaven Lab is also playing a leading role in DUNE. This Fermilab-based experiment will send beams of elusive subatomic particles called neutrinos hundreds of miles through Earth’s crust to detectors deep underground in South Dakota. Understanding how neutrinos change as they travel may help unravel mysteries about how our universe evolved, including potentially an asymmetry between matter and antimatter that accounts for our universe being composed mostly of matter. Brookhaven physicists and staff helped develop the methods for creating neutrinos, simulations for testing and controlling characteristics of the beam, specialized electronics and other detector materials needed to study key neutrino characteristics, and the software and computational tools that will be used to capture neutrino signals and process vast quantities of data. Brookhaven scientists are leading the design of a third underground detector module for DUNE, highlighted in the P5 report as part of a re-envisioned second phase of this project.

Going beyond the secrets of the matter that makes up our world and its scantly present antimatter partner, Brookhaven scientists seek to explore the unknowns of so-called dark matter and dark energy, which are highlighted among the scientific drivers for new discoveries by the P5 panel and together make up more than 95% of our universe. One tool for this research is a telescope that will be housed at the Vera C. Rubin Observatory high on a mountaintop in Chile. The DOE-funded effort to build the camera for the telescope was managed by SLAC National Accelerator Laboratory. Brookhaven Lab led construction of the camera’s 3.2 gigapixel “digital film”—the biggest charge-coupled device (CCD) array ever built—and will support the telescope’s Legacy Survey of Space and Time (LSST). LSST will be an unparalleled wide-field astronomical survey of our universe—wider and deeper in volume than all previous surveys combined.

Brookhaven Lab is also actively engaged in developing small- and medium-scale facilities and experiments and in building capabilities in machine learning/artificial intelligence, quantum information science, and microelectronics that will help to push the frontiers of discovery in high energy physics with potential benefit for other fields. The Lab is also committed to attracting, building, and supporting a diverse workforce to carry out these ambitious research programs, and to fostering a climate of innovation.

Mysterious cosmic ray observed in Utah came from beyond our galaxy, scientists say

KATIE HUNT CNN

Few things in space are as bright as a supernova, but recently astronomer captured a flash out in the cosmos so great their instruments had trouble measuring it. Gamma ray burst GRB 2210099A, which was so bright not only was it named, but it’s what experts believe is also the birth of a black hole.

Space scientists seeking to understand the enigmatic origins of powerful cosmic rays have detected an extremely rare, ultra-high-energy particle that they believe traveled to Earth from beyond the Milky Way galaxy.

The energy of this subatomic particle, invisible to the naked eye, is equivalent to dropping a brick on your toe from waist height, according to the authors of new research published Thursday in the journal Science. It rivals the single most energetic cosmic ray ever observed, the “Oh-My-God” particle that was detected in 1991, the study found.


An artist's illustration of the extremely energetic cosmic ray observed by the Telescope Array Collaboration led by the University of Utah and the University of Tokyo. It's been named the "Amaterasu particle."

Cosmic rays are charged particles that travel through space and rain down on Earth constantly. Low-energy cosmic rays can emanate from the sun, but extremely high-energy ones are exceptional. They are thought to travel to Earth from other galaxies and extragalactic sources.

“If you hold out your hand, one (cosmic ray) goes through the palm of your hand every second, but those are really low-energy things,” said study co-author John Matthews, a research professor at the University of Utah.

“When you get out to these really high-energy (cosmic rays), it’s more like one per square kilometer per century. It’s never going through your hand.”

Despite years of research, the exact origins of these high-energy particles still aren’t clear. They are thought to be related to the most energetic phenomena in the universe, such as those involving black holes, gamma-ray bursts and active galactic nuclei, but the biggest discovered so far appear to originate from voids or empty space — where no violent celestial events have taken place.

Tracking high-energy cosmic rays

The recently discovered particle, nicknamed the Amaterasu particle after the sun goddess in Japanese mythology, was spotted by a cosmic ray observatory in Utah’s West Desert known as the Telescope Array.

The Telescope Array, which started operating in 2008, is made up of 507 ping-pong table-size surface detectors covering 270 square miles.

It has observed more than 30 ultra-high-energy cosmic rays but none bigger than the Amaterasu particle, which struck the atmosphere above Utah on May 27, 2021, raining secondary particles to the ground where they were picked up by the detectors, according to the study.

“You can look … (at) how many particles hit each detector and that tells you what the energy of the primary cosmic ray was,” Matthews said.

The event triggered 23 of the surface detectors, with a calculated energy of about 244 exa-electron volts. The “Oh My God particle” detected more than 30 years ago was 320 exa-electron volts.

For reference, 1 exa-electron volt equals 1 billion gigaelectron-volts, and 1 gigaelectron volt is 1 billion electron volts. That would make the Amaterasu particle 244,000,000,000,000,000,000 electron volts. By comparison, the typical energy of an electron in the polar aurora is 40,000 electron volts, according to NASA.

An ultra-high-energy cosmic ray carries tens of millions of times more energy than any human-made particle accelerator such as the Large Hadron Collider, the most powerful accelerator ever built, explained Glennys Farrar, a professor of physics at New York
 University.




“What is required is a region of very high magnetic fields — like a super-sized LHC, but natural. And the conditions required are really exceptional, so the sources are very very rare, and the particles are dissipated into the vast universe, so the chances of one hitting Earth are tiny,” said Farrar, who wasn’t involved in the study, via email.

The atmosphere largely protects humans from any harmful effects from the particles, though cosmic rays sometimes cause computer glitches. The particles, and space radiation more broadly, pose a greater risk to astronauts, with the potential to cause structural damage to DNA and altering many cellular processes, according to NASA,.

Mysterious source

The source of these ultra-high-energy particles baffles scientists.

Matthews, a co-spokesman for the Telescope Array Collaboration, said the two biggest recorded cosmic rays appeared “sort of random” — when their trajectories are traced back, there appears to be nothing high-energy enough to produce such particles. The Amaterasu particle, specifically, seemed to originate from what’s known as the Local Void, an empty area of space bordering the Milky Way galaxy.

“If you take the two highest-energy events — the one that we just found, the ‘Oh-My-God’ particle — those don’t even seem to point to anything. It should be something relatively close. Astronomers with visible telescopes can’t see anything really big and really violent,” Matthews said.

“It comes from a region that looks like a local empty space. It’s a void. So what the heck’s going on?”

An expansion to the Telescope Array may provide some answers. Once completed, 500 new detectors will allow the Telescope Array to capture cosmic ray-induced particle showers across 2,900 square kilometers (about 1,120 square miles) — an area nearly the size of Rhode Island, according to the University of Utah statement.

Extremely energetic cosmic ray detected, but with no obvious source

An extremely energetic cosmic ray – an extragalactic particle with an energy exceeding ~240 exa-electron volts (EeV) – has been detected by the Telescope Array experiment’s surface detector, researchers report. However, according to the findings, its arrival direction shows no obvious source. Ultrahigh-energy cosmic rays (UHECRs) are subatomic charged particles from space with energies greater than 1 EeV – roughly a million times as high as the energy reached by human-made particle accelerators. Although low-energy cosmic rays primarily emanate from the sun, the origins of rarer UHECRs are thought to be related to the most energetic phenomena in the Universe, such as those involving black holes, gamma-ray bursts, and active galactic nuclei. Yet much about the physics and acceleration mechanisms of these particles remains unknown. Because arrivals of the most energetic UHECRs are so infrequent – estimated to be less than one particle per century per square kilometer – their detection requires instruments with large collecting areas. Here, members of the Telescope Array Collaboration report the detection of an extremely energetic cosmic ray observed by the Telescope Array (TA) experiment, a surface cosmic-ray detector array located in Utah, USA, that has an effective detection of 700 square kilometers. According to the findings, the unusually high-energy cosmic ray arrived on 27 May 2021 and had a calculated energy of about 244 EeV. Given the particle’s exceptionally high energy, the authors note that it should only experience relatively minor deflections by foreground magnetic fields, and thus, its arrival direction should be expected to be more closely correlated to its source. However, the findings show that its arrival direction shows no obvious source galaxy, or any other known astronomical objects thought to be potential sources of UHECRs. Instead, its arrival direction points back to void in the large-scale structure of the Universe – a region where very few galaxies reside. The authors suggest that this could indicate a much larger magnetic deflection than is predicted by galactic magnetic field models, an unidentified source in the local extragalactic neighborhood, or an incomplete understanding of the associated high-energy particle physics.

Survey finds most Americans are unaware of many signs that someone is having a seizure


Seizures don’t always look how they’re portrayed in movies, and knowing the more subtle signs like laughing or lip-smacking behavior may lead to diagnosis and effective treatment for epilepsy

Orlando, Fla - If you’ve ever seen a movie or TV show in which a character has a seizure, you probably have a fairly standard mental picture of someone falling to the ground in full body convulsions while foaming at the mouth. But that doesn’t necessarily reflect reality. A new national survey by Orlando Health finds that while most Americans recognize those classic symptoms of what’s called a generalized tonic-clonic seizure, the majority fail to recognize the subtle signs, all of which can be dangerous and have a profound impact on the lives of those suffering from them.

“Anything that interrupts your brain’s circuit can cause seizures, from tumors, infections and strokes to high or low blood sugar or glucose levels to inherited genetic features. And different types of seizures can present with dozens of different symptoms,” said Dipali Nemade, MD, MPH, an epileptologist and neurologist at the Orlando Health Neuroscience Institute. “But because they often look different than those ‘cinematic seizures’ we see in movies and television, they can go undiagnosed for a long time.”

The survey, conducted by Ipsos, found less than half of Americans believe numbness or tingling (32%), blinking rapidly (35%), crying out or screaming (13%) and laughing (6%) are signs of a seizure, but Dr. Nemade says it’s important to pay attention to any odd or out-of-place behaviors and address them with your doctor.

“Even seizures with these less dramatic symptoms can make everyday activities like driving and cooking dangerous. For some people, their seizures present outwardly with very subtle signs like smacking their lips, picking at their clothes or just staring into space, and it’s important to recognize when you or someone around you is experiencing them so they can be accurately diagnosed and treated,” Dr. Nemade said. “By looking at their brainwaves (EEG), we can see if those behaviors are being caused by seizures.”

For Mike Sail, seizures start with a flushed feeling that travels from his abdomen to his throat, followed by raised arm hair causing his condition to initially be misdiagnosed as acid reflux. It wasn’t until he lost his memory of an entire week that he was finally referred to Dr. Nemade, who diagnosed his condition as epilepsy. 

“I kept saying that it can’t be acid reflux because that doesn't cause the hair on your arms to stick up,” Sail said. “For the most part, these episodes were not very disruptive. They only lasted a minute or two and usually only happened once every few weeks. Sometimes I’d have them while I was doing things like playing golf, and afterwards I would just go about my business. So, I was shocked to find out they were seizures because it wasn’t what most people think a seizure looks like.” 

Like most cases, Sail’s epilepsy is well-controlled with anti-seizure medication, lifestyle changes and adequate sleep, and he no longer fears that uneasy feeling he gets before having what he now knows were seizures. Dr. Nemade says education is needed to help others like Sail raise a red flag when they’re having unexplained symptoms on a regular basis.

“If people don’t know that these symptoms can be caused by epileptic seizures, their condition will be misdiagnosed or ignored and it will continue to affect their quality of life. That can be very isolating and frustrating, which is why many people with uncontrolled epilepsy experience anxiety and depression,” Dr. Nemade said. “Too many people never go to the doctor because they don’t feel like it is profoundly affecting their lives, or they don’t know how to explain what they’re feeling.”

For rare cases of epilepsy that are resistant to anti-seizure medication, there are some advanced treatments that Dr. Nemade and her team offer at the Orlando Health Neuroscience Institute’s epilepsy center, such as intracranial monitoring (sEEG/subdural) and mapping the brain to find the exact spot where seizures are originating and removing a small piece of tissue. If they are not able to remove the tissues safely, then neuromodulation options like responsive neurostimulation, deep brain stimulation and vagus nerve stimulation are effective palliative options. It’s effective treatments like these that are not only improving lives, but also saving them by preventing sudden unexpected death in epilepsy, or SUDEP, which claims about 3,000 lives in the U.S. each year. But Dr. Nemade says they can only help if symptoms are recognized and action is taken.

If you suspect someone is experiencing a seizure, sit them down in a safe place without any sharp or heavy objects in their surroundings and ensure they can breathe freely until symptoms subside. If a seizure lasts more than five minutes, call 911. Those who have never received an epilepsy diagnosis or another explanation for their seizure should follow up with their doctor or a neurologist.

Mike Sail plays a board game with his wife, Ann, while hooked to an IV treatment as part of his seizure care plan. Hair standing up on his arms and a flushed feeling that starts in his abdomen were misdiagnosed as acid reflux until he underwent testing at the Orlando Health Neuroscience Institute to determine that, for him, these were symptoms of seizures.

Dipali Nemade, MD, conducts a neurological examination on a patient at her clinical office at the Orlando Health Neuroscience Institute. The exam tests behavior, movements and mental function to assist in diagnosing seizures. A national survey by Orlando Health found that most people are unaware of many of the subtle signs of a seizure.
