What statements is false concerning fetal alcohol spectrum disorders FASD?

One false statement concerning fetal alcohol spectrum disorders (FASD) is that FASD can only occur if the mother consumes alcohol heavily during pregnancy. In reality, even low to moderate alcohol consumption can potentially lead to FASD, as there is no known safe amount of alcohol during pregnancy. Additionally, FASD is not always associated with physical features; cognitive and behavioral issues can occur even in the absence of visible symptoms.
