[Diagnosis of fetal alcohol spectrum disorders].

Prenatal alcohol exposure may cause decreased growth of the child, congenital abnormalities, specific facial characteristics, and, most importantly, mental retardation and behavioural disorders, all known as fetal alcohol spectrum disorders (FASD). A significant number of pregnant women in the Netherlands drink alcohol, but the prevalence of FASD in our country is unknown. Repeated and high peak blood alcohol concentrations, for example in the case of binge drinking by the mother, result in more severe abnormalities; a safe limit for alcohol consumption in pregnancy cannot be defined.
