Researchers will use advanced brain imaging and blood tests to explore biological markers—changes in blood pressure, heart rate and pupil reactivity—that could predict which children will develop persistent symptoms after concussion.

The National Institute of Neurological Disorders and Stroke has awarded a $10-million grant to the Four Corners Youth Consortium, a group of academic medical centers studying concussions in school-aged children. Led in part by the Safe Concussion Outcome Recovery and Education (SCORE) program at Children’s National Hospital, the project is named Concussion Assessment, Research and Education for Kids, or CARE4Kids.

Researchers will use advanced brain imaging and blood tests to explore biological markers—changes in blood pressure, heart rate and pupil reactivity—that could predict which children will develop persistent symptoms after concussion. The five-year CARE4Kids study will enroll more than 1,300 children ages 11-18 nationwide.

The five-year study will be led by Gerard Gioia, Ph.D., division chief of Neuropsychology at Children’s National Hospital, Frederick Rivara, M.D., M.P.H., at Seattle Children’s Center for Child Health, Behavior and Development and University of Washington’s Medicine’s Department of Pediatrics, and Dr. Chris Giza at University of California, Los Angeles (UCLA).

“We will be gathering innovative data to help answer the critical question asked by every patient: ‘When can I expect to recover from this concussion?’” said Dr. Gioia. “We have a great team and are excited to have been selected to study this important issue.”

Christopher G. Vaughan, Psy.D., neuropsychologist, and Raquel Langdon, M.D., neurologist, both at Children’s National, will join Dr. Gioia as principal investigators of the study at this site.

Every year, more than 3 million Americans are diagnosed with concussions. Symptoms continue to plague 30 percent of patients three months after injury—adolescents face an even higher risk of delayed recovery. Chronic migraine headaches, learning and memory problems, exercise intolerance, sleep disturbances, anxiety and depressed mood are common.

“Providing individualized symptom-specific treatments for youth with a concussion has been a longstanding aim of the SCORE program,”Dr. Vaughan said. “This project will lead to a better understanding of the specific markers for which children may have a longer recovery. With this knowledge, we can start individualized treatments earlier in the process and ultimately help to reduce the number of children who experienced prolonged effects after concussion.”

The grant was announced on September 9, 2021.

In Washington, D.C., an estimated 240 children ages 11 to 18, will participate in the study.

The study will unfold in two phases. The first part will evaluate children with concussion to identify a set of biomarkers predictive of persistent post-concussion symptoms. To validate the findings, the next stage will confirm that these biomarkers accurately predict prolonged symptoms in a second group of children who have been diagnosed with concussion. The goal is to develop a practical algorithm for use in general clinical practice for doctors and other health professionals caring for pediatric patients.

Institutions currently recruiting patients for the study include Children’s National Hospital, UCLA Mattel Children’s Hospital, Seattle Children’s, the University of Washington, University of Rochester, University of Texas Southwestern Medical Center and Wake Forest School of Medicine. Indiana University, the National Institute of Nursing Research, University of Arkansas, University of Southern California and the data coordinating center at the University of Utah are also involved in the project.

Earlier research conducted by the Four Corners Youth Consortium that led to this project was funded by private donations from Stan and Patti Silver, the UCLA Steve Tisch BrainSPORT Program and the UCLA Easton Clinic for Brain Health; Children’s National Research Institute; as well as from the Satterberg Foundation to Seattle Children’s Research Institute; and an investment from the Sports Institute at UW Medicine.

Researchers awarded $3.5 million to study brain and cranium development in children

Currently, studies on typical brain and cranium development are limited. One reason for this is that imaging techniques are optimized to best visualize either bone or soft tissue, but not both.

With prevalence of developmental disorders on the rise, the need to understand brain development has never been more critical. Development of the brain is strongly influenced by the cranium, but this relationship has not been adequately studied because of limitations in imaging technology. Now, researchers from Children’s Hospital Los Angeles and Children’s National Hospital are working together to develop techniques that will provide greater insight into this relationship. Their studies will be funded by The National Institute of Dental and Craniofacial Research, which has awarded them $3.5 million.

Natasha Leporé, Ph.D., of Children’s Hospital Los Angeles, studies methods to interpret brain imaging data. “There’s a lot of interaction between the skull and the brain,” she says, “and we want to better understand how they grow together.”

Currently, studies on typical brain and cranium development are limited. One reason for this is that imaging techniques are optimized to best visualize either bone or soft tissue, but not both.

The brain — mostly composed of water, protein and fat — doesn’t show up well on computerized tomography (CT) scans, which use X-ray images. In addition, radiation exposure limits the amount of CT scan data available in children. On the other hand, magnetic resonance imaging (MRI) scans are excellent for brain images but are not optimal for surrounding bone.

This presents researchers with a dilemma if they want to see the brain and the skull together in one image. Fortunately, research barriers like these are often overcome by collaboration.

Leporé will work with Marius George Linguraru, D.Phil, M.A., MS.c., principal investigator in the Sheikh Zayed Institute for Pediatric Surgical Innovation at Children’s National Hospital.

Linguraru works on a set of tools for cranial phenotyping, using existing CT images from typically developing children. In their collaboration, Leporé and Linguraru will extend the tools to MRI scans, allowing the team to analyze the brain and cranium simultaneously. The pair has received a $3.5 million award over 5 years.

“The tools we develop together will help us to better understand the healthy growth of children,” says Linguraru. “We will have the ability to analyze the joint cranial and brain development from large medical image datasets of pediatric patients.”

This, the team says, will be invaluable to the medical community.

“These tools will help clinicians to better assess, diagnose and plan treatment for infants with cranial deformities,” says Linguraru.

Collaborations like this allow expertise to be shared across specialties, ultimately benefiting children in need. Exceptional pediatric care is a result of teamwork; not only doctors, nurses and clinical staff, but also biomedical research, which arms clinicians with the information they depend on.

“We need to have a clear idea of what is expected in normal development,” says Leporé. “This allows doctors to detect and better understand differences in development.”

Other members of the research team include: Vidya Rajagopalan, Ph.D.; Marvin Nelson, M.D.; Alexis Johns, Ph.D.; Niharika Gajawelli, Ph.D. (from Children’s Hospital Los Angeles and University of Southern California); Robert Keating, M.D. (Children’s National Hospital); Yalin Wang, Ph.D. (Arizona State University); Antonio Porras, Ph.D. (University of Colorado); Sean Deoni, Ph.D. (Rhode Island Hospital and Brown University).
