Rebounding Back to Life, Dominic Perseveres Past Pediatric Stroke

Dominic Donati, then 9, eating for the first time six days after he suffered multiple strokes.

Sometimes it is the simplest of moments that can bring a family with a child in the hospital the most hope. For Tony and Laurie Donati, such a moment occurred when a neurologist at Seattle Children’s Neurosciences Center handed their son Dominic Donati a pen and paper and asked him to write a sentence only days after suffering multiple strokes.

Unable to speak at the time, Dominic, then 9, wrote, “Hi. My name is Dom.”

“It makes me cry every time I think about him writing this incredibly simple sentence,” Laurie, his mom, said. “Dominic’s stroke was the most awful thing that has ever happened to our family. I think everyone in the room felt excited because it was the first time we knew that he could still communicate with us.” Read full post »

When Rare Epilepsy Struck Toddler, Diet Paved Road to Recovery

Our son, Sam, goofing around at home days before he developed a life-threatening form of epilepsy known as febrile infection-related epilepsy syndrome.

Parents David and Jennifer Cowan share how the rapid initiation of a special medical diet known as the ketogenic diet helped their son recover by leaps and bounds after he suffered from a rare, life-threatening form of epilepsy known as febrile infection-related epilepsy syndrome (FIRES). For more about how the ketogenic diet is used to treat epilepsy, please see a Q&A with the ketogenic diet team from Seattle Children’s Neurosciences Center.

Over the summer of 2017, our 4-year-old son Sam came down with a high fever that lasted about a week. Seemingly recovered, a day or two later he awoke as normal, snuggled and watched morning cartoons. But shortly after, and completely unexpectedly, Sam began to seize uncontrollably and stopped breathing. Read full post »

Food as Medicine: High-Fat Keto Diet Prescribed to Treat Epilepsy

Neurologists at Seattle Children’s prescribe the ketogenic diet for the treatment of epilepsy and other neurological conditions.

Doctors first started using the ketogenic diet to treat patients with epilepsy in the 1920s. While the diet has evolved over the decades to include less strict versions, and is gaining mainstream popularity for weight loss, children with epilepsy and other neurological conditions continue to benefit from its seizure-controlling effects.

The ketogenic diet team at Seattle Children’s Neurosciences Center takes a modern approach to help families use food as medicine. Here, ketogenic diet team members, neurologist Dr. Christopher Beatty; advanced practice provider Haley Sittner; clinical dietitian Marta Mazzanti; and nurse Deborah Rogers discuss how the diet works and how the team sets families up for success on the ketogenic diet.

Out of Breath? Braking Neurons Play Surprising Role in Rapid Breathing

New research from Seattle Children’s offers fresh insight into how the brain sets the pace of breathing.

Next time a workout has you winded, the inhibitory neurons in your brain may be to blame. This is according to new research from Seattle Children’s Research Institute that offers fresh insight into how the brain sets the pace of breathing.

In a study published in the journal Nature Communications, researchers used laser light to manipulate very specific classes of neurons responsible for breathing. The technique, known as optogenetics, helps scientists isolate neurons in the brain to study their function.

When stimulated in the lab, the researchers found excitatory neurons – the brain’s go signal – actually slow breathing, while inhibitory neurons – the brain’s stop signal – intervene to make breathing more rapid. In addition to explaining how the brain adapts breathing in response to everyday cues, the finding could lead to more precise treatments for neurological conditions that frequently involve breathing abnormalities.

Study Finds Neuron Inhibition May be Key in New Treatments for Addiction

New research suggests inhibiting one group of neurons’ activity may prove to be a highly effective treatment for reducing relapse in recovering addicts.

A new study published by researchers from Seattle Children’s Research Institute reveals how neurons in the brain fuel drug-seeking behavior following compulsive drug use. Their findings, published online in Addiction Biology, suggest inhibiting one group of neurons’ activity may prove to be a highly effective treatment for reducing relapse in recovering addicts.

While the science of addiction is beginning to show how pathological drug use causes the brain’s “go” pathway to become overactive, little is known about what renders some individuals vulnerable to developing addiction and what protects others against it. There are also few effective treatments available to people who develop a drug addiction, or the approximately 90% of individuals who relapse following addiction treatment.

Dr. Susan Ferguson, a principal investigator in the Center for Integrative Brain Research at Seattle Children’s and senior author on the study, describes how her team used an experimental approach called chemogenetic inhibition to probe the relationship between brain activity and behavior in drug addiction.

A New Approach to Caring for Kids with Tuberous Sclerosis Complex

Luke Avansino, now 8, was diagnosed with tuberous sclerosis complex, a rare genetic disorder, as an infant.

Eight years ago, Dr. Jeff Avansino, a surgeon at Seattle Children’s, and his wife, Dr. Amy Criniti, welcomed their third child – a boy named Luke.

For the first few months of Luke’s life, he developed as expected. At about 6 months old, he started having spells of irritability. Avansino and Criniti, both physicians, thought it was likely due to a virus. But Luke’s spells continued.

“My wife has good intuition and knew something was wrong,” Avansino said. “She started looking into his symptoms and thought he might be having infantile spasms, or seizures.”

They took Luke in for tests and Criniti was right – Luke was having seizures. Doctors also found light colored patches on his skin. Further testing confirmed that Luke has a rare genetic disorder called tuberous sclerosis complex (TSC). Read full post »

Discover the Seattle Children’s Stories You Might Have Missed in 2017

With 2018 in full effect, On the Pulse is taking a moment to hit rewind to share five stories that might have floated beneath the flurry of headlines in 2017.

We invite you to take a look back at some of last year’s stories that inspired us and gave us hope.

1. A Mother’s Intuition Leads to Picture-Perfect Treatment of Eye Cancer

Amanda De Vos, a professional photographer, was reviewing shots she took of her 15-month-old identical twin daughters, Julia and Jemma, when a photo of Julia caught her attention.

De Vos would learn that the photo she took of Julia would help to identify a rare eye cancer, retinoblastoma, that was stopped in its tracks with an innovative treatment at Seattle Children’s.

With a Genetic Answer, Parents Find Comfort in Son’s Rare Epilepsy

Genetic testing helped diagnose Nolan Wood, 3, with KCNQ3 epilepsy.

Even though Nolan Wood hadn’t experienced a seizure in more than two years, his parents still had questions about their son’s future.

“We wondered if there were others out there that have what Nolan has,” said Emily Wood, Nolan’s mom. “If so, what does their life look like?”

The Woods’ search for answers began when Nolan, 3, was diagnosed with infantile spasms and regression of his motor skills when he was 6 months old. Before receiving seizure medications, Nolan had hundreds of daily subtle, reflex-like seizures. Due to the regression of his motor skills, he had stopped rolling over, smiling and crying. A condition known as cortical visual impairment had also rendered him legally blind. Read full post »

Surgery Frees Lillee from Seizures Medication Couldn’t Stop

Lillee Haynes, 4, surrounded by her three older brothers.

When 4-year-old Lillee Haynes runs through the doors of Seattle Children’s South Clinic for her speech therapy appointment and heads straight for a table covered in crayons, it’s hard to imagine that nearly two years ago she faced hundreds of epileptic seizures each day.

“Her seizures happened so often that I installed a camera above her bed to record any she had at night,” said Aimee Haynes, Lillee’s mom. “One night the camera recorded 200 movements. I was shocked to see how many seizures disrupted her sleep.”

Lillee’s brain didn’t rest until she underwent not one, but two neurosurgeries at Seattle Children’s to remove the diseased area of her left brain, allowing her healthy brain to grow and develop.

“You could say Lillee is most definitely right-brain dominant,” laughed Haynes. “That might explain why she has such a spicy personality.” Read full post »

Researchers Put Youth Sports Safety and Concussion Awareness Ahead of the Game With Novel Program

Seattle Children’s researchers will launch an innovative program in early 2018 aimed at shifting the culture of safety in youth sports and building concussion awareness during competitive play.

The program, called One Team, emphasizes community engagement in conducting brief pre-game safety huddles involving coaches, officials, parents and athletes, with a goal of addressing both sportsmanship and the importance of removing an athlete from play if they potentially have a concussion.

Dr. Sara Chrisman and Dr. Emily Kroshus, both members of the Seattle Pediatric Concussion Research Collaborative and Seattle Children’s Center for Childhood Health, Behavior and Development, designed the program.

“We want to change how children, parents and coaches relate to injuries, and reinforce a line in athlete safety that shouldn’t be crossed, even in a competitive atmosphere,” Chrisman said.
