RT Journal A1 Albert DM, Blanchard J, Knox BL T1 ENsuring appropriate expert testimony for cases involving the “shaken baby” JF JAMA JO JAMA YR 2012 FD July 4 VO 308 IS 1 SP 39 OP 40 DO 10.1001/jama.2012.6763 UL http://dx.doi.org/10.1001/jama.2012.6763 AB For the past 50 years, the “shaken baby” syndrome has been one of the many terms used to describe a form of abusive head trauma in children. The term now preferred is pediatric abusive head trauma (AHT), which is defined 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.”1- 2 This new term reflects the fundamental construct that certain forms of head trauma are intentionally inflicted. The incidence is estimated to be 20 to 30 cases per 100 000 children younger than 1 year, and the case-fatality rate exceeds 20%.1 Abusive head trauma causes significant disability for about two-thirds of survivors1 and also results in major health care costs.
