Pediatric Traumatic Brain Injury

Signs and symptoms of TBI vary, depending on the site and extent of injury to the brain, the age at which the injury occurred, premorbid abilities, and functional domains affected (e.g., physical, cognitive, language, sensory). The effects of TBI can be temporary or permanent, and no two children present with the same pattern.

Some young children with TBI may demonstrate relatively typical developmental progression after the initial stages of recovery. Others continue to have long-term difficulty learning new information and negotiating more complex social interactions due to impairments in cognitive functions (Anderson, Godfrey, Rosenfeld, & Catroppa, 2012; Turkstra, Politis, & Forsyth, 2015).

The functional impact of TBI in children can differ from that in adults because the pediatric brain is still developing. For example, sensory systems and the frontal lobes of the brain continue to develop past late adolescence (S. J. Taylor, Barker, Heavey, & McHale, 2013). Therefore, some children may not present with immediate effects of TBI, but will experience challenges later in their development, particularly as academic  demands increase (Gerrard-Morris et al., 2010; H. G. Taylor et al., 2008). These difficulties can affect educational and vocational outcomes; friendships; participation in home, school, and community; and overall quality of life (Catroppa & Anderson, 2009; Gamino, Chapman, & Cook, 2009).

The full sequelae of pediatric TBI can emerge and/or persist well into adulthood, lending to the perspective that TBI in children is a chronic disease process rather than a one-time event (DePompei, 2010; DePompei & Tyler, in press; Masel & DeWitt, 2010).

Signs and symptoms may co-occur with other existing developmental conditions such as attention-deficit/hyperactivity disorder, learning disabilities, autism spectrum disorder, intellectual disability, childhood apraxia of speech, childhood fluency disorders, late language emergence, spoken language disorders, written language disorders, and social communication disorders.

Considerations for Infants and Toddlers With TBI

Infants and toddlers may lack the communication or developmental skills to overtly report the signs and symptoms of TBI noted above. Clinicians and families need to be aware of the following signs that may be initially observed after TBI for this age group:

  • Changes in the ability to pay attention
  • Changes in eating or nursing habits
  • Changes in play (e.g., loss of interest in favorite toys/activities)
  • Changes in sleeping habits
  • Irritability, persistent crying, and inability to be consoled
  • Lethargy
  • Loss of acquired language
  • Loss of new skills, such as toilet training
  • Sensitivity to light and/or noise
  • Unsteady walking, loss of balance

In cases of abusive head trauma such as shaken baby syndrome, sometimes there are no apparent external physical signs to indicate a TBI. Attention to behavioral symptoms such as those listed above is critical (Cox, 2016).

For infants and toddlers, acute deficits following TBI tend to be in skill areas that are developing at the time of injury. Lack of overt deficits in these very young children just after TBI does not mean that they will not require services later. For skills that are not fully developed at the time of injury, later-onset symptoms can arise, including memory and attention deficits, language delay or deficits, and behavioral problems. These younger children are also more likely to have difficulties academically compared with children who were injured at later ages (Anderson, Catroppa, Morse, Haritou, & Rosenfeld, 2005). The full extent of deficits may become evident only as the child's brain matures and expected skills fail to develop or emerge more slowly (McKinlay & Anderson, 2013).
