Consensus statement on abusive head trauma in infants and young children

Area of Science:

• Pediatrics
• Neurology
• Forensic Medicine

Background:

• Abusive head trauma (AHT) is the primary cause of fatal head injuries in children under two years old.
• Diagnosis relies on a multidisciplinary approach, integrating patient history, physical examination, imaging, and laboratory results.
• The term AHT encompasses multifactorial injury mechanisms, including shaking, impact, or combined forces.

Purpose of the Study:

• To provide a consensus document clarifying the medical diagnosis of AHT.
• To differentiate evidence-based medical findings from speculative theories presented in legal contexts.
• To equip judges and jurors with tools to assess medical evidence accurately.

Main Methods:

• Review of medical literature and clinical findings related to AHT.
• Identification of diagnostic components of AHT, such as subdural hematomas, retinal hemorrhages, and fractures.
• Exclusion of medical conditions that mimic AHT.
• Analysis of proposed but unsubstantiated etiological theories for AHT.

Main Results:

• AHT diagnosis is supported by specific injuries inconsistent with reported trauma mechanisms.
• Medical evidence does not support cerebral sinovenous thrombosis, hypoxic-ischemic injury, lumbar puncture, or dysphagic choking/vomiting as causes of AHT.
• There is no evidence that asymptomatic birth-related subdural hemorrhages cause rebleeding and collapse later in life.

Conclusions:

• AHT is a medical diagnosis based on objective findings, not a legal determination of intent or murder.
• Distinguishing between genuine medical evidence and unsupported etiological speculations is crucial in AHT cases.
• This consensus aims to reduce confusion and promote evidence-based decision-making in legal proceedings involving AHT.
