5 things pediatricians should know about seizures

Seizures can bring up a lot of worries and unknowns, especially when it comes to children.

One percent of the population has epilepsy, which puts the estimated number of children with epilepsy in Orange County alone at about 7,500. It is estimated that one in five people will have a seizure at some point—whether it develops into epilepsy or not—making seizures a more common neurological condition than multiple sclerosis, Parkinson’s and Alzheimer’s disease combined.

There are many common misconceptions about seizures, even within the medical community. Dr. Mary Zupanc, pediatric neurologist and epileptologist and co-medical director of CHOC’s Neuroscience Institute, points to five important points pediatricians should consider when seeing a patient who has had one or more seizures.

  1. There should be zero tolerance for seizures.

    Seizures are considered epilepsy when a child has had two or more unprovoked seizures—seizures that are not tied to a different underlying condition.

    When epilepsy is diagnosed, treatment should be initiated early. Some families are reluctant to treat their child’s epilepsy, often fearful that antiepileptic medication is worse than epilepsy itself. They worry about the side effects — that it will cause their child to have cognitive impairments and slow them down. However, repeated seizures can translate into progressive injury to the brain, with a decline in cognitive abilities and frequent psychosocial co-morbidities, including anxiety and depression. Furthermore, even if seizures are infrequent, there is a loss of independence for children and adolescents. An example would be an adolescent’s inability to obtain his/her driver’s license.

  2. Epilepsy is progressive.

    “Brain cells that seizure together network together,” Dr. Zupanc says, forming neuronal circuitry that hardwires the brain for continued seizures. Over time, there can be brain cell loss, cognitive decline, and important psychosocial consequences. Furthermore, when seizures continue, there is increased risk among those with epilepsy of sudden, unexpected death or other progressive neurological issues over the subsequent 20-30 years.

  3. Encourage parents to act quickly.

    Recurrent unprovoked seizures is the definition of epilepsy. Epilepsy should be treated and not ignored, for the reasons outlined above. Approximately 60-70% of epilepsy can be completely controlled with antiepileptic medication. Thirty percent of patients with epilepsy have intractable seizures, i.e. a failure to control the seizures with antiepileptic medications. These patients require more comprehensive care, including an evaluation for epilepsy surgery — at a Level IV Epilepsy Center, which is a designated center given only to those centers who provide multidisciplinary care with cutting-edge technology. Some parents fear that epilepsy surgery will cause serious neurological deficits. Most epilepsy surgeries are highly successful without detrimental effects to cognitive or motor functions. With epilepsy surgery, the risk of a severe and permanent injury is under 1%, and the risk of a minor or temporary injury is under 5%. Compared to the risks associated with years of recurrent seizures, the risks of epilepsy surgery are much lower than the risks of continued epilepsy.  

    The effectiveness of epilepsy surgery decreases significantly over time, especially for children who have had epilepsy for seven or more years. In addition, the plasticity of younger brains allows a transfer of functions to other parts of the brain — something adult brains cannot do as readily, Dr. Zupanc says.

    Because of this, she strongly encourages epilepsy surgery early, not waiting until a child is older.

  4. Delay in seizure treatment affects long-term psychological health.

    The psycho-social components of seizures are oftentimes just as important as the physiological ones, says Dr. Zupanc. Depression and anxiety occur in 50- to 60% of children with epilepsy, and there is also a notable increase in suicidal risk.

    These effects are increased when families wait to pursue recommended surgery, she says. Later in life, the surgery may remove the seizures, but the psychological effects are already deeply embedded.

  5. Seizure history should affect your referral choice.

    “It is so important for pediatricians to know that if a child’s epilepsy has not come under complete control after trying two or more antiepileptic medications, he/she should be referred to a higher level of epilepsy care, specifically a Level III-IV Epilepsy Center, as designated by the National Association of Epilepsy Centers,” says Dr. Zupanc. If the child is a young baby, the referral is even more urgent. “If a baby continues to have seizures after just one drug, he/she needs a referral to a Level III-IV epilepsy center immediately.”

    The care plan should include pediatric epilepsy specialists, epilepsy-trained neurosurgeons, state of the art neuroimaging tools, nurse practitioners, pharmacists, dieticians, social workers and neuropsychologists.

    “At CHOC, we treat epilepsy with a multidisciplinary team approach,” says Dr. Zupanc. Additional diagnostic tests are usually necessary to diagnose the appropriate epilepsy syndrome, determine if epilepsy surgery is an option, and/or outline an individualized, optimal treatment plan.

    Furthermore, all of those involved in the child’s care hold a comprehensive epilepsy conference to discuss complex cases and lay out the best possible strategy for achieving a seizure-free outcome.

CHOC Children’s leaders observe International Women’s Day

As the world celebrates International Women’s Day, we turned to CHOC Children’s female physicians and nursing leaders for insight and words of encouragement to other women pursuing healthcare careers.

Melanie Patterson, vice president, patient care services, and chief nursing officerWhen beginning your career in medicine, don’t focus on one trophy. The fields of medicine and nursing have so many opportunities within them; be courageous and try new things. The most important aspect of leadership and of career success is to be kind. Remember to form your own opinion — go into every relationship with your eyes open and stop looking through others’ eyes; they don’t always have 20/20 vision.

Dr. Mary Zupanc, pediatric neurologist and epileptologist & co-medical director of the CHOC Children’s Neuroscience Institute

When I went to medical school, women were not encouraged, and it was hard. There were a lot of things that happened that made it very difficult, but medicine is truly one of the most gratifying professions you will ever have. Every patient is different. I believe that if you really and truly listen, a patient and their family will give you the diagnosis you’re searching for. Everyone’s story is so fascinating, and that makes our work like being a detective. Sometimes I feel like Sherlock Holmes searching for answers. Then once you do find an answer, you need to work with the family to make sure the treatment works for their lifestyle, culture and religion. That makes the work challenging, fun and meaningful.

The best piece of advice that I’ve ever received is to never apologize for excellence. Anyone would want their doctor to strive for excellence – and that goes for any profession.

Amy Waunch, nurse practitioner and trauma program managerNever underestimate your capabilities. Do not shy away from opportunities and always take on new challenges. Believe in yourself but don’t be afraid to ask for help. You may not have all of the answers all of the time, but you do have the ability to learn and grow.

Spot growth opportunities when they present themselves because they are the key learning opportunities. You will know because they make you uncomfortable and your initial impulse will be that you are not ready.

Dr. Azam Eghbal, medical director, radiologySince I was 7 years old, I wanted to be a doctor and becoming one has been the best decision of my life. As a female immigrant, I was told that I could never get to medical school, which, of course, motivated and challenged me even more to do so. The best advice I’ve gotten is don’t be discouraged about all your falls and obstacles. Think how you can succeed to get where you want to be.

Dr. Amber Leis, pediatric plastic surgeonMy advice for women pursuing a career in medicine is to trust yourself! Early on in your career, it’s easy to be overcome by feeling like you are not up to the task ahead of you. Your unique qualities will become your greatest strengths, so just keep chasing your passion.

I have great faith that if I stay true to my core principles, the right path will open in front of me. I try not to set specific goals for the future and instead I give my best to where I am. It keeps me focused on what I am doing now, and not distracted by trying to maneuver into some future place.

The best piece of career advice I’ve ever gotten has been, “You get to choose what kind of person you will be.”

Dr. Jasjit Singh, medical director, infection prevention & controlMy advice for women pursuing a career in medicine is to follow your passion! There are few other careers that offer the personal satisfaction and the intellectual rigor that medicine does. Find a good mentor early in your career. Later, make sure your practice partners have abilities that you respect, and the talent to make your shared time together meaningful.

I learned early on that delegation and time management are important, particularly if you want to balance a medical career and family. You can’t always do it all, and prioritization is tantamount to success in all the different spheres of your life.

One of the best pieces of advice that I got was from a mentor during fellowship, who told me, “It’s not enough to just be a good clinician.” He showed me the importance of asking good research questions and pursuing new knowledge. He also encouraged my love of teaching upcoming generations of pediatricians!

Dr. Katherine Williamson, pediatricianI love being a pediatrician. I help take care of kids every day and partner with their parents to help keep them healthy. To me, being successful is loving what you do, because then working hard and being motivated to do well doesn’t feel like work – it’s fulfilling a passion.

When asked to give advice, I always say these three things: be yourself, don’t rush, and follow your heart every step of the way. Be yourself, always. No matter how busy or loud life gets, never lose sight of you who you are and what you want to do.  Don’t be in a rush. Enjoy the journey because that is where you learn who you truly are. Lastly, follow your heart in every decision you make. When I look back on what got me to where I am in my career, I realize that it was not one or two big decisions that were the deciding factor, but instead it was a million little decisions along the way. And with each of those decisions I followed my heart and my passion.

Seizure-free after a rare epilepsy diagnosis

Thanks to the expertise of a CHOC Children’s epileptologist, a 12-year-old boy diagnosed with a rare type of epilepsy is seizure-free and has a bright future ahead – the significance of which is underscored in November, Epilepsy Awareness Month.

Gabriel Lucak had been a healthy, normally developing child until age 3, when he suddenly began experiencing seizures.

What began as a tonic-clonic seizure in May 2008 rapidly progressed to include myoclonic, atonic, and atypical absence seizures. On his worst days, Gabriel experienced up to 50 seizures a day.

“It was like living out a surreal nightmare,” said his mother, Nicole.

Gabriel was initially diagnosed with myoclonic-astatic epilepsy, also known as Doose syndrome. His seizures were difficult to control, and doctors attempted many different treatments, including eight months on a ketogenic diet. During this time, Gabriel was hospitalized numerous times to modify his medication and control his seizures.

Searching for answers

A low point for the Lucak family came about nine months after the seizures began. While hospitalized for respiratory syncytial virus, Gabriel’s seizures increased significantly. An electroencephalogram (EEG) recorded seizures occurring about once a minute and a slowing brain wave frequency. Magnetic resonance imaging (MRI) revealed decreased brain volume. Gabriel’s health was rapidly deteriorating.

Joe and Nicole desperately began looking elsewhere for help, and in March 2009 found a beacon nearly 1,400 miles away in Dr. Mary Zupanc, a pediatric neurologist and one of the nation’s leading epileptologists, who was then practicing in Wisconsin.

Under Dr. Zupanc’s care, Gabriel was placed on a new treatment program. He stopped following the ketogenic diet and began taking a new antiepileptic medication. He underwent a two-week long-term video EEG monitoring study, which revealed he was experiencing a fifth type of seizure – tonic – during sleep.

A new diagnosis

Dr. Zupanc then knew that Gabriel’s epilepsy had evolved into a more severe form called Lennox-Gastaut syndrome (LGS). This rare type of epilepsy is marked by seizures that are difficult to control, and typically persist through adulthood.

In addition, Dr. Zupanc diagnosed Gabriel with cerebral folate deficiency, a rare metabolic condition, following a spinal tap and extensive testing on his cerebral spinal fluid. He immediately began taking a folinic acid supplement and following a strict dairy-free diet.

Under this new treatment plan, Gabriel was seizure-free within two months. A second spinal tap showed a normal level of folate, and another MRI had normal results. The Lucaks were thrilled.

“Gabriel could have suffered severe brain damage, or he might not have survived at all,” Nicole said. “That’s how critical it was for us to have found Dr. Zupanc when we did.”

A bright future

Today, Gabriel is an intelligent, creative and artistic 12-year-old who dreams of being a paramedic when he grows up.

He remains under Dr. Zupanc’s care, traveling from San Diego to the CHOC Children’s Neuroscience Institute and its level 4 epilepsy center for appointments and annual long-term EEG monitoring.

Gabriel is also under the care of Dr. Jose Abdenur, chief of CHOC’s metabolics disorders division. Gabriel, his younger brother, Nolan, and his parents have all participated in several research studies involving genetic testing for both epilepsy and cerebral folate deficiency.

Recently, Gabriel was weaned off the antiepileptic medication and continues to be seizure-free.

“He has the opportunity to live a full life in good health, thanks to an amazing series of events that led to experienced doctors, correct diagnoses and effective treatment,” Nicole said.

Infantile Spasms: What Pediatricians Should Know

Though seizures in children are always worrisome, pediatricians should be especially watchful for infantile spasms, a type of epilepsy that occurs in young infants typically between ages 3 and 8 months, a CHOC Children’s neurologist says.

These seizures should be considered a medical emergency due to the potentially devastating consequences on the developing brain, Dr. Mary Zupanc says. Many children with infantile spasms go on to develop other forms of epilepsy because a developing brain undergoing an epileptic storm essentially becomes programmed for ongoing seizures and cognitive/motor delays.

To that end, here’s what pediatricians should look for:

  • Infantile spasms often occur in clusters, with each spasm occurring every five to 10 seconds over a period of minutes ranging from three to 10 minutes or longer.
  • Though there is almost always a cluster of spasms in the morning when the child awakens from sleep, infantile spasms can occur at any time during the day or night.

Infantile spasms can be easily missed because they can mimic common symptoms and conditions such as sleep disturbances, gastroesophageal reflux, startle and shuddering attacks.

Diagnosis, treatment

If infantile spasms are suspected, a pediatrician should quickly refer the child to a pediatric neurologist. CHOC neurologists admit these children urgently for long-term video electroencephalogram (EEG) monitoring to confirm the diagnosis.

Infantile spasms are diagnosed on the basis of clinical spasms, in association with a markedly abnormal EEG showing a hypsarrhythmia pattern. A hypsarrhythmia pattern is characterized by very high amplitude electrical activity and multifocal areas of the brain demonstrating epileptic discharges.

High-dose adrenocorticotropic hormone, or ACTH, is CHOC neurologists’ first line of treatment for infantile spasms, per the American Academy of Neurology’s 2004 practice parameter. Vigabatrin (Sabril), the parameter states, is probably effective in the treatment of infantile spasms, especially in children with tuberous sclerosis and infantile spasms.

If started within four to six weeks of seizure onset therapy has better success at stopping spasms, eliminating the hypsarrhythmia pattern and improving developmental outcomes regardless of etiology.

The course of treatment is approximately six weeks. During this time, and for two to three months after the ACTH course, immunizations should not be administered. The effectiveness of ACTH may be as high as 85 percent, though a recent published study placed the efficacy at a slightly lower percentage, regardless of etiology.

Side effects, causes

Side effects of ACTH, a steroid, include high blood pressure, increased appetite and weight gain, increased sugar in the blood, temporary suppression of the immune system, and sometimes gastritis. All side effects are monitored during the time of the ACTH, and they disappear after the course of treatment.

Successful therapy is marked by two achievements: the cessation of the infantile spasms and the elimination of the hypsarrhythmia pattern. But because clinical spasms can be very subtle and the hypsarrhythmia pattern may sometimes only be seen during deep sleep, therapy’s success can only be confirmed through objective long-term video EEG monitoring.

The etiologies for infantile spasms can include:  tuberous sclerosis; cortical dysplasias; stroke; infection including meningitis and encephalitis; hypoxic-ischemic injury; trauma; or genetic conditions such as Down syndrome and metabolic disorders.
