Abusive head trauma refers to head, neck or brain injury that happens when someone shakes or hits a baby on their own purpose and it can easily hurt a baby. It only takes 1 or 2 hard shakes to seriously hurt a baby’s brain that result in development of shaken baby syndrome,a type of abusive head trauma.

Babies have large and heavy heads in comparison with their bodies, and their necks remain vulnerable to getting injured easily.They can’t have the full control over their head movement as easily as older children or adults do.If you shake a baby,it can vigorously move their head backward and forward in a very quick succession.

  • History of prematurity or low birth weight
  • Multiple births like tweens,triplets births.
  • Unplanned pregnancy together with social and emotional difficulties.

Caregiver and family-related factors may also augment the risk of happening of abusive head trauma in children who are still very young.These comprise young parents with limited social support, low socioeconomic status, low self-confidence, limited education, or lack of prenatal care with additional risks that may arise from limited childcare experience, difficulty managing stress or frustration.

Mental health challenges, substance use, single-caregiver situations, or previous involvement with child protective services also assist in the happening of abusive head trauma. Certain community-level factors that have the close association for further increased vulnerability are:

  • Social isolation with restrictive access to amusing spaces.
  • Poverty along with Unemployment. 
  • Exposure to domestic violence that comprise partner violence
  • Lack of adequate community support services. 

Incidence rate of abusive trauma to the child

The accurate proven rate of determination of abusive head trauma in children remains challenging and this is due to the absence of a centralized reporting system.It also accumulates the variability of clinical presentations.That is why there is frequent underrecognition of abuse in the family. Abusive head trauma often results from uninterrupted maltreatment rather than it generally having the association of a single acute event. 

In the United States (US), the approximate evidence based incidence of acute head trauma in children who are younger than 1 year generally calculates from 25 to 35 per 100,000 in each year.Abusive head trauma (AHT) is the most common cause of fatal physical abuse in children and the infants are the most vulnerable group who account for the majority of related deaths.

Age Variation who possess acute head trauma

The incidence of abusive head trauma in children actually has a peak age between 6 and 8 weeks and it lines up with the period of excessive infant crying, namely “purple crying period.” The report of mortality rates due to abusive head trauma in families ranges from 10% to 20% and it has a significant drop rate after 1 year of age.Thereby it makes the overall count approximately 3.8 per 100,000 annually.

Geographical distinction of abusive head trauma

Geographic distinction of abusive head trauma in children has been perceived within the entire US.The experts counted the highest incidence based on evidence in the Midwest and the lowest in the Northeast of the country. There is no clear or conclusive explanation that has been notified for these regional variations across the country. 

Sentinel Injuries of the child to cause abusive head trauma

Sentinel injuries frequently antecede a formal diagnosis of child ill-treatment.Consequently it almost counts nearly 25% of children who are later diagnosed with abuse present with previously unacknowledged injuries.Among the findings,bruising and intraoral trauma are the  common ones and it is more particularly in children younger than 3 years of age.As many as 20% of these cases may go unrecognized during initial medical evaluations.  

Variation in Clinical Practice

Clinical practice variation further has the effects on diagnosis of abusive head trauma in children and this is due to biases on caregiver demographics and socioeconomic status.Moreover ethnicity may also affect assessment verdicts.Standardized screening protocols can enhance the identification of abusive head trauma (AHT) and thereby help ensure more consistent evaluation and treatment when ultimately reduce variations and disparities in patient care. 

How abusive head trauma affects a child’s brain and bodily systems 

The factors like biomechanical forces are closely involved in AHT typically include combinations of rotational along with translational, and impact forces. These injury processes may be the outcome of violent shaking, blunt impact, or both simultaneously. Experimental studies comprising computational models, human surrogates together with animal research, and postmortem analyses have emerged the concept of how such forces injure your child’s brain. 

Infants are particularly more susceptible due to close associations of several anatomical and physiological features that favours the occurrence of head trauma.Thereby this also includes a relatively large head-to-body ratio, immature neck musculature,excessive ligamentous laxity, partially ossified skull, and higher intracranial fluid content. These characteristics help amplify the impacts of acceleration-deceleration and rotational forces and thus end up with increasing the risk for diffuse brain injury as well as making them prone to get abusive head trauma in children.

Possible outcomes of abusive head trauma to the child 

Constant shaking can cause the head and neck to move rapidly back and forth which thereby can help stretch and damage your child’s brain blood vessels.After that this may lead to bleeding such as subdural hematoma, subarachnoid hemorrhage, and brain swelling inside your baby’s skull. As pressure inside the skull increases, blood flow to the brain may fall than normal level and also cause injury. Similar to traumatic brain injury, diffuse axonal damage can also affect a baby’s brain function and result in fluctuation in coordination. Direct impact may also cause fractures or concussions.
