Fetal Alcohol Syndrome (cont.)
What causes fetal alcohol syndrome?
The ultimate cause is alcohol intake by the pregnant mother. However, alcohol itself may not be directly responsible for all (or any) of the features of FAS. What may be responsible are byproducts generated when the body metabolizes ("burns") alcohol. The end result is a decrease in the number of brain cells (neurons), abnormal location of neurons (due to disturbance of their normal migration during fetal development), and gross malformation of the brain.
