I always loved the start of a new school year—the crisp notebooks, freshly sharpened pencils, new teachers, new classmates, and the excitement of discovering something new every day. But what if going back to school wasn’t exciting anymore? What if returning to the classroom felt harder than it used to? What if this school year is different because you’re different?
For many children recovering from a traumatic brain injury, that’s exactly what happens. Even after the bruises have healed and the headaches have faded, they may struggle with attention, memory, mental fatigue, emotional regulation, or keeping up with schoolwork. These challenges are often invisible to others, but they can have a profound impact on a child’s education, friendships, confidence, and future.
Keep reading to learn what research tells us about pediatric brain injury, and why returning to school is about much more than simply showing up on the first day.
Long-Term Neurodevelopmental Outcome of Children With Mild Traumatic Brain Injury
A new study published in Pediatric Neurology followed children for more than three years after a mild traumatic brain injury and found that some continued to experience subtle but meaningful difficulties with attention, thinking, behavior, and school performance long after the initial injury.1
Researchers followed 89 children who had sustained a mild traumatic brain injury and compared them with 89 healthy peers of similar age, sex, and socioeconomic background. The encouraging news is that overall intelligence remained within the average range for children who had experienced a concussion. However, the study also identified several significant differences.
Compared with their peers, children who had received a mild TBI were more likely to experience challenges that affect learning and everyday functioning, like difficulties with attention and concentration, increased hyperactivity and impulsivity, reduced information processing speed, weaknesses in visual memory, and lower reading performance for up to two years after injury. One surprising finding was that traditional clinical factors, such as the characteristics of the initial injury, did not reliably predict which children would experience long-term difficulties.
The effects identified in this study are often subtle. A child may no longer complain of headaches or dizziness but still struggle to keep up in the classroom, stay organized, complete assignments, or regulate attention. Because these difficulties may emerge months after the injury, or become more noticeable as school demands increase, they can easily be mistaken for behavioral problems, lack of effort, or attention disorders unrelated to the concussion. If these issues become concerning, a comprehensive evaluation—including neuropsychological, occupational therapy, speech-language, or educational assessments—may help identify the appropriate intervention to help children receive the educational accommodations and rehabilitation services they need to reach their full potential.
Are Pediatric Biomarkers a Thing?
Diagnosing and predicting recovery after brain injury has always been a challenge, but with children it can be especially tough. Two children with similar injuries can have vastly different recoveries, making it difficult for families and healthcare providers to know what lies ahead. But now, researchers at the University of Pittsburgh have identified a unique biological “signature” in children with moderate to severe TBI that could one day help doctors better predict recovery and customize treatment. 2
Researchers studied blood samples from children who had never experienced a brain injury or neurological disorder before sustaining a TBI. The samples were collected at different points during recovery—from the first few hours after the injury through the following year—and compared with blood samples from children who had orthopedic injuries, such as broken bones, but no brain injury.
The researchers discovered that children with a brain injury had a unique biological pattern in their blood shortly after the injury. Over time, these changes gradually returned to levels like those seen in children without a brain injury, suggesting that the biological changes may reflect the brain’s healing process. Another important finding was that these biological changes did not match the child’s score on the Glasgow Coma Scale (GCS), a tool commonly used in emergency departments to assess the severity of a brain injury. This suggests that traditional measures of injury severity may not tell the whole story about how a child’s brain is recovering.
Because things change over time, researchers believe the biomarker may eventually become a useful way to monitor recovery and even evaluate how treatments such as rehabilitation, physical activity, nutrition, or other therapies support the brain’s healing process. While much more research is needed before this can influence everyday clinical care, it opens the door to precision rehabilitation—tailoring treatment to each child’s unique biology rather than relying solely on the initial injury severity.
The Association Between Sleep and Emotional Functioning in Pediatric Mild Traumatic Brain Injury: A Scoping Review.
When a child sustains a mild TBI, parents often focus on headaches, dizziness, or getting back to school and sports. But one symptom is frequently overlooked: sleep. The findings of a scoping review from the Journal of Neurotrauma highlight the importance of addressing sleep as an important part of supporting both the brain and emotional well-being after injury. 3
Researchers reviewed nine studies involving more than 1,250 children with mild traumatic brain injury. Across the studies, one finding was consistent: children who experienced poorer sleep were also more likely to experience emotional difficulties, including symptoms of anxiety, depression, irritability, and mood changes.
During sleep, the brain restores energy, consolidates memories, regulates hormones, and supports emotional processing. Emotional distress such as anxiety or depression can make it harder to fall asleep or stay asleep, creating a cycle in which sleep and emotional symptoms may reinforce one another. Disrupted sleep after a concussion can make it more difficult for children to regulate their emotions, manage stress and frustration, concentrate in school, remember new information, and participate in daily activities.
Researchers have not yet determined whether sleep problems lead to emotional symptoms, emotional symptoms disrupt sleep, or whether both processes occur simultaneously.
But what we do know is that helping children recover from mild traumatic brain injury requires a whole-child approach. Good sleep habits can play a key role in concussion recovery. Maintaining a consistent bedtime, limiting screen time before bed, creating a quiet sleep environment, and following healthcare providers’ recommendations may all help facilitate sleep and support healing.
Parental Observations of Concussion: The Hidden Impact on School Performance
When a child sustains a concussion, the immediate focus is often on physical recovery—headaches, dizziness, and when it’s safe to return to sports. But for many children, the biggest challenges don’t appear on the field. They show up in the classroom.
A recent study in the Journal of School Health found parents frequently report ongoing academic issues after their child’s brain injury, even once the physical symptoms improved, which reinforces the importance of keeping an eye on school performance and learning long after the concussion occurs. Early support can prevent children from falling behind academically while their brains continue to heal.
Many children are medically cleared to return to school before their brains have fully recovered. As classroom demands increase, lingering cognitive symptoms may become more noticeable. A child who once excelled academically may suddenly struggle to focus, organize assignments, or complete tests within the allotted time. These changes can be frustrating for both children and families, especially when the injury itself appears to have healed. The study highlights that recovery should be measured not only by the absence of symptoms but also by a child’s ability to participate successfully in everyday activities, especially learning.
Successful recovery often requires collaboration between families, healthcare providers, and schools. Parents should let teachers know if their child is experiencing ongoing symptoms, and schools should be prepared to provide temporary accommodations when needed. These may include:
- Reduced homework or shortened school days
- Extra time for tests and assignments
- Scheduled rest breaks
- Reduced screen time
- Modified workloads during recovery
If academic problems continue for several weeks—or new challenges emerge after returning to school—it may be time for additional evaluation. Occupational therapists, neuropsychologists, speech-language pathologists, and educational specialists can assess cognitive functioning and recommend strategies to support learning.
Pediatric Brain Injury At Trial: Why “Mild” Doesn’t Always Mean Minor
When a child suffers a traumatic brain injury (TBI), the visible signs often fade quickly. The emergency department visit is over. The child returns to school. Brain scans may even appear normal. To an outside observer, it may be that the injury is behind them.
But an increasing body of scientific research tells quite a different story—one that is especially important in the courtroom. Today’s evidence demonstrates that pediatric brain injuries, even those classified as mild, can produce subtle but lasting changes that affect learning, emotions, behavior, and everyday functioning for years after the initial trauma. For attorneys, juries, and families, these findings reinforce an important truth: the absence of visible injury does not mean the absence of significant harm.
While many children recover quickly, not every child follows the same path. Research tracking children for more than three years after a mild TBI has shown that some continue to experience difficulties with learning skills and behavior long after headaches and other physical symptoms have resolved. Grades may decline, homework may take longer to complete, mental fatigue can interfere with learning, and standardized testing may become more difficult. Teachers and parents may notice changes in attention, organization, or classroom behavior that were never present before the injury.
Recovery involves more than cognitive skills. Sleep disturbances are common after pediatric concussion and are closely linked to emotional health. Children who struggle with sleep are more likely to experience anxiety, depression, irritability, mood swings, and difficulty regulating their emotions. These changes can affect relationships with family and friends, participation in school, and overall quality of life.
Importantly, these emotional and behavioral changes should not automatically be dismissed as reactions to the injury or typical childhood behavior. Growing evidence suggests they may reflect ongoing changes in the recovering brain.
One of the greatest challenges in pediatric brain injury litigation is that the most significant impairments are often invisible on routine imaging. The diagnosis of “mild traumatic brain injury” refers to the severity of the initial injury—not the severity of its long-term consequences. Every child deserves to be evaluated based on how the injury affects their ability to learn, develop, build relationships, and reach their full potential.
Academic records, report cards, teacher observations, neuropsychological evaluations, Individualized Education Programs (IEPs), Section 504 plans, and testimony from parents and rehabilitation professionals can provide powerful evidence of how a brain injury has changed a child’s daily functioning and future opportunities.
At Cantor Grana Buckner Bucci, we understand that pediatric brain injuries are rarely defined by what appears on a CT scan or MRI. Our goal is to present the complete story of how a brain injury has affected a child’s life, education, relationships, and future. We collaborate closely with medical specialists, rehabilitation professionals, educators, neuropsychologists, and families to document the full impact of a child’s injury, not just in the days after the accident, but over the months and years that follow. Because when a child’s future is at stake, understanding the science behind pediatric brain injury is essential to achieving justice.
