History of the definition process
Dr. John Caffey started defining Shaken Baby Syndrome (SBS) and Abusive Head trauma (AHT) in 1946 when he described the association of subdural hemorrhages with long bone fractures. In 1972 and 1974, he published the seminal article describing the clinical features with the radiologic findings associated with shaking injuries. The term ‘ Shaken Baby Syndrome’ was first used by Ludwig and Warman in 1984 when they reviewed 20 infants and toddlers injured from being shaken. It was Duhaime et al in 1998 who provided evidence that the shaken babies could also have injuries related to blunt force trauma. Some researchers today believe the models and theories are incomplete in their ability to completely understand the components of Abusive Head Trauma and Shaken Baby Syndrome.
The American Academy of Pediatrics believes AHT in infants and young children is a settled scientific fact. According to the AAP
The scientific support for the diagnosis of AHT comes from over 40 years of research in a broad array of clinical and basic science disciplines, including pediatrics, neurosciences, ophthalmology, orthopedics, radiology, pathology, epidemiology, and biomechanics.http://www.ncsl.org/Portals/1/Documents/fsl/Understanding_AHT_Infants_Children_AAP_FINAL_6-15.pdf
Components of Abusive Head Trauma
Severely shaking an infant can cause neurologic injury. Blunt force trauma to the head can cause additional injuries including superficial injury, cranial fracture, etc. Abusive head trauma (AHT) is considered to include both components: forcible shaking of an infant or toddler (Shaken Baby Syndrome) and blunt force trauma from hitting or slamming an infant or child’s head against something hard.
The CDC and others consider Shaken Baby Syndrome as a subsidiary of AHT.
