Alcohol consumption during pregnancy may produce permanent brain damage in the fetus and is associated with the development of a life-long behavioral, social, and cognitive disorder now known as fetal alcohol spectrum disorder (FASD). The most clinically recognizable form of FASD is fetal alcohol syndrome (FAS) which is characterized by specific features including facial dysmorphogenesis, mental dysfunction, growth retardation, and cardiovascular and limb defects.
