Question
What are possible signs and symptoms of pediatric abusive head trauma (PAHT)?
Answer
e there's no humane way to test pediatric abusive head trauma, the study took car crash mannequins and looked at the force of impact on the spine and the brain. Of the 131 mannequins in the crash simulations, 96% met the criteria for a spinal injury, while only 22% met pediatric abusive head trauma criteria.
As a clinician, I am now much more curious about my kiddos, who I know were involved in stressful early caregiving experiences. They may not have a diagnosis of pediatric abusive head trauma or even some symptoms, but what is the likelihood of some spinal damage that may result in low muscle tone, frustration, or increased pain response? Because of this study, we know that it's highly possible and likely that roughly cared-for babies may experience neck and spinal injuries before any neurological impact or PAHT.
PAHT and Cerebral Functioning
Animal simulations of pediatric abusive head trauma have highlighted a clear connection between subdural hematomas and oxygen loss that occur during shaking or other abusive interventions. The initial cerebral impact can stop oxygen during shaking or other abusive interactions. Loss of oxygen means long-term damage to cells within the brain, which can result in a lack of weight gain, growth restriction, and ongoing respiratory concerns. It can also cause issues with your frontal cortex, which is cause and effect, working memory, reading comprehension, and other things that come much later down the developmental trajectory.
Long-Term Outcomes
Thinking about the long term, pediatric abusive head trauma can cause learning disabilities, fine and gross motor delays, speech delays, cerebral palsy, seizures, and cognitive impairments. Cerebral palsy is a cluster of symptoms that can be diagnosed from a myriad of onsets. Still, it is possible that an event of pediatric abusive head trauma could result in a cerebral palsy diagnosis.
Cerebral Damage
Our brain has three primary regions that impact our social-emotional functioning: the frontal cortex, which sits at the front of your brain, your limbic system, and your brain stem. The frontal cortex supports cause-and-effect, impulse control, and higher levels of thinking. Damage in this area will result in increased impulsivity, difficulty with self-regulation, and learning difficulties. Our limbic system supports access to words and memory. Damage in this area may result in speech delays or speech loss and concerns with long-term, short-term, and working memory. Our brain stem is responsible for heart rate, blood pressure, and body temperature. Damage to the brain stem is generally life-threatening.
