Prince George’s County Installs Advanced Concussion Management System, XLNTbrain Sport™

“There’s No Such Thing as a ‘Concussion-Proof’ Helmet,” Neurologist Says”

NATIONAL HARBOR, MD (September 29, 2014) — Responding to the growing concern over the short and long-term effects of sports-related concussions, Prince George’s County Public Schools System (PGCPS) has implemented an advanced concussion management system called XLNTbrain Sport™ to aid in the prevention and detection of concussions, as well as guiding the return-to-play and return-to-learn decisions resulting from mild traumatic brain injury.

Prince George’s county is the second largest school district in Maryland and one of the top 25 largest school districts in the nation. According to Earl Hawkins, director of athletics for PGCPS, approximately 8,000 athletes are using the new concussion protocol, making it the largest installation for XLNTbrain in the country.

Hawkins said initially, he selected XLNTbrain because he wanted every athlete to undergo cognitive baseline testing, which the system provides an advanced version, and to provide the latest in concussion management technology to assist with student-athlete safety.

“Baseline testing is the starting point to help determine if an athlete has a concussion and it helps the medical professionals with their evaluation,” Hawkins said. “But XLNTbrain is more than baseline tests, it’s very comprehensive,” he said, referring to the system’s compliant education program, sideline assessment tool, and recovery program and reporting capabilities.

“I like it because I can print reports by team and individual so I can track their progress on testing, education and concussion recovery,” Hawkins said. “Knowing it was created by a neurologist with expertise in this area is also a plus.”

Harry Kerasidis, MD — based in National Harbor — is the neurologist behind XLNTbrain Sport™. The system combines technology and neurology to create the first all-inclusive, single-platform concussion management protocol for all sports and all levels. XLNTbrain provides compliant education, baseline neuro-cognitive testing, identification of concussion using the XLNTbrain mobile app, and a progressive exertion recovery program based on Dr. Kerasidis work with hundreds of concussed patients.

“There’s no such thing as a ‘concussion-proof’ helmet,” said Dr. Kerasidis, the Medical Director of the Center for Neuroscience at Calvert Memorial Hospital. “The brain is vulnerable and until now there hasn’t been a single platform concussion protocol that meets and exceeds guidelines set by the National Athletic Trainers Association, the American Academy of Neurology and other medical organizations, as well as the NFL, meeting my clinical approval. It’s like having a virtual neurologist on the sideline.”

The Centers for Disease Control and Prevention estimates between 1.6 and 3.8 million sports and recreation-related concussions occur in the United States each year. The CDC says that 10 percent of all college players and 20 percent of all high school players sustain concussions in any given season, with high school athletes three-times more likely to sustain a second concussion.

XLNTbrain Sport™ is also being used by the following Maryland and DC athletic programs:

Gilman School
Towson Sports Medicine
Concordia Academy
Maryvale Preparatory School
Prince Georges County (DC suburbs)
Salisbury University
St. Mary's College (Southern Maryland)
