Concussion is a common injury, especially among children. While most recover quickly, some experience symptoms that linger for weeks or even months. A new study suggesting blood protein to detect concussion recovery in children, presented by researchers at the Murdoch Children’s Research Institute (MCRI) has identified a potential tool for early detection of children at risk of delayed concussion recovery. Let’s get into detail about all the possible aspects of this study.
The research, published in the Journal of Neurotrauma, explored the role of a specific blood protein, alpha-1-antichymotrypsin (alpha-1-ACT), in childhood concussion recovery. The study involved children aged 5-18 who presented to the emergency department at The Royal Children’s Hospital within 48 hours of suffering a concussion. Blood samples were collected, and researchers compared alpha-1-ACT levels between children with typical recovery and those experiencing delayed recovery.
Blood Protein to Detect Concussion
The study revealed significantly lower levels of alpha-1-ACT in children with delayed recovery. This suggests that alpha-1-ACT may serve as a biomarker, a measurable indicator of a biological process, for identifying children at risk of prolonged concussion symptoms.
MCRI researcher Ella Swaney emphasizes the importance of early detection in concussion management. “Concussion is a growing public health concern,” she says. “With 25-30% of children experiencing long-term symptoms after a concussion, there’s a critical need for tools to identify those most at risk of delayed recovery.”
Delayed recovery from concussion can encompass a range of emotional, behavioral, physical, and cognitive symptoms. These can significantly impact a child’s well-being, affecting their ability to return to school and sports activities. Early detection allows for the implementation of targeted interventions, leading to faster and more effective recovery.
Findings Improve Clinical Management
Professor Vicki Anderson of MCRI highlights the impact of this research. “This is the first human trial to identify alpha-1-ACT as a possible marker for delayed concussion recovery,” she says. “If validated in larger studies, this finding could significantly improve clinical management by providing doctors with a tool for early identification and potentially guiding more timely and targeted treatments for children most likely to experience long-term problems.”

Critical Case Study: Mackenzie’s Journey to Recovery
The case study features Mackenzie, a 16-year-old who suffered a concussion during a netball game. She describes the initial impact of the injury, including dizziness, confusion, nausea, light sensitivity, memory loss, headaches, and muscle soreness. These symptoms, along with mental health challenges, caused her to miss several weeks of school.
Mackenzie’s story highlighted the benefits of early intervention. She enrolled in MCRI’s Concussion Essentials Plus program, a program specifically designed for children with persistent concussion symptoms. The program involved physiotherapy and psychology treatments, along with education on returning to exercise, school, and sports activities. “It was a slow recovery process,” Mackenzie says, “but the intervention helped me return to my normal self again.”
Karen Payne, Mackenzie’s mother, expresses her hope for the future impact of this research. “The possibility of easily identifying children at risk of long-term symptoms would be a huge relief for families,” she says. “Early intervention can make a world of difference in speeding up the recovery process.” In 2023, a large international study, co-led by MCRI researchers, addressed all aspects of concussion care, including revised exercise and rehabilitation protocols, updated return-to-school and return-to-sport guidelines, and the development of the HeadCheck App. This app, designed by MCRI concussion experts, assists in early concussion recognition and recovery management.

The findings from a study of blood protein to detect concussion add to the growing body of knowledge on concussion management. With further investigation, alpha-1-ACT has the potential to become a valuable tool for identifying children at risk of delayed concussion recovery, paving the way for more effective interventions and improved outcomes.
