Fetal alcohol spectrum disorder (FASD) is a term used to describe a number of problems that can result in people whose mothers drank alcohol during pregnancy. FASD includes a variety of mental, physical, behavioural and learning disabilities. If a pregnant woman drinks any alcohol at any time during pregnancy, the alcohol crosses the placenta to the fetus. Alcohol damages the developing cells of the fetus. The brain and central nervous system are particularly sensitive to alcohol and can suffer permanent damage. Any amount of alcohol can have some effect, so there is no minimum amount of alcohol in pregnancy that is safe. The developing fetus can't break down the alcohol as quickly as an adult, so its exposure to alcohol is actually higher than the mother's.
