Shaken baby syndrome

Shaken baby syndrome is a constellation of medical findings: subdural hematoma, retinal bleeding, and brain swelling from which physicians, consistent with current medical understanding, infer child abuse caused by violent shaking. In a majority of cases there is no visible sign of external injury. The Centers for Disease Control and Prevention identifies SBS as "an injury to the skull or intracranial contents of an infant or young child (< 5 years of age) due to inflicted blunt impact and/or violent shaking".
