Mild Traumatic Brain Injury & Concussion in Children & Adolescents 

Are you worried about a child, adolescent or young adult, who has suffered a mild traumatic brain injury or concussion, or repeated concussions over time?

Traumatic Brain Injuries are diagnosed as mild, moderate or severe. Mild Traumatic Brain Injuries  (mTBIs) or concussions are more common in children, adolescents or adults than moderate or severe traumatic  brain injuries. Both concussions and mTBIs involve injuries to the brain which are considered mild and non-life threatening.

Have you been told, or do you believe, that there is nothing to worry about, that the effects of a mild traumatic brain injury or concussion are likely to be relatively benign and short lived?

Unfortunately, this is not always the case. Some young people who suffer a mild TBI or concussion will exhibit long term negative effects. These can contribute to behavioral and/or academic and learning problems. This is true even when brain imaging scans show no sign of a brain injury, or when the young person has recovered from the primary symptoms associated with the acute injury stage. Brain imaging techniques may not reveal the varied, severe and complex injuries that can result from a TBI or concussion, and that can contribute to learning and behavioral problems in young people. 

While concussions and mTBIs are considered mild because they are not life threatening,   research indicates that 40% of children with a history of  mTBI or concussion exhibit a range of long term negative effects. 

(Brownwell, 2024) reported that " 70 to 90 % of reported TBI cases are categorized as "mild" yet as many as 90% of mTBI cases go undiagnosed", even though their effects can be serious and last for years. These can show up as neurocognitive impairments, such as memory, attention, processing speed and executive function problems. Cognitive impairments like these are often at issue in the persistent academic difficulties that these children may show following  a concussion or mild TBI.

What Are Your Concerns?

 Is a young person who suffered a mild traumatic brain injury or concussion failing to show signs of recovery? Is he or she exhibiting persistent long-term negative effects, or what the literature describes as post concussive symptoms.

If so, you are likely discouraged and unsure of how to help, and there is little guidance to assist you.  MTBI's, for example, do not typically show up on brain scans, so it is difficult to determine the extent of the injury or its existence.

In addition, our understanding of traumatic brain injury in children, especially a mild TBI or concussion is limited. Most studies of traumatic brain injury have focused on adults. Research, although sparse, suggests that the outcome of a brain injury may be worse in children, than adults. 

Furthermore, we know more about moderate to severe brain injuries in young people, than we do about mTBI or concussion. We also know more about the effects of mTBI in adults, than we do about the effects of mTBI in children and adolescents.

Moreover, the effects of a brain injury in children differs from its effects in adults. These effects are thought to be more detrimental and long lasting in children and adolescents due to the developing nature of the immature brain. This applies to a mild brain injury or concussion, as well as to moderate and severe traumatic brain injuries.

No two brain injuries are alike, and multiple risk factors contribute to the course a mild TBI or concussion will take in each individual case. While many will move on after a mTBI with no lasting ill effect, numerous others will continue to struggle, long after the onset of the injury?

Help for Mild Traumatic Brain Injury

Dr. O'Connor offers comprehensive in depth school neuropsychological assessments.

School neuropsychological assessments are recommended when a young person with a past or recent head injury, or repeated head injuries, shows academic or behavioral difficulties. It is also not unusual for children who have suffered a brain injury, including a mTBI to show signs of recovery and  normal functioning, only to exhibit learning and/or behavorial problems later as their brains mature.

Consequently, it is important to monitor young people with a known or suspected head injuries for future academic and behavioral problems.  A school neuropsychological re-evaluation can help when this is the case.

Understanding a traumatic brain injury and its effects on a child or adolescent's school functioning  is critical. This applies to young adults who are pursuing post secondary education.  A school neuropsychological assessment increases understanding of how a brain injury, or series of head injuries, has impacted the young person's behavioral and academic functioning, and provides evidence based solutions to address these concerns.

A school neuropsychological assessment can assist when a young person has suffered a mild TBI or concussion, and is showing concerns. School neuropsychological testing quantifies the severity of the child's impairments and provides objective, valid and reliable measures of cognition, emotions, personality and behavior. These results can also help inform an effective , evidence based intervention program.
