Fetal alcohol syndrome (FAS), currently considered part of fetal alcohol
spectrum disorder (FASD), was first described in 1973.1 Although
much has been learned in 30 years, substantial challenges remain in diagnosing
and preventing this disorder. Our goal is to summarize what has recently been
reported with respect to fetal alcohol terminology, identification, effects,
prevalence, and prevention of exposure. We will emphasize how fetal alcohol
exposure is routinely underidentified and what is known about who is at risk.
With this knowledge, physicians should be better able to identify at-risk
pregnancies and alcohol-affected individuals and address fetal alcohol exposure
in the clinical setting.
