How is fetal alcohol syndrome (FAS) diagnosed?
Making a diagnosis of FAS can be difficult because there are no particular medical tests or procedures available to make such a determination. In addition, some of the symptoms of FAS resemble those found in other disorders such as attention-deficit/hyperactivity disorder (ADHD) and Williams syndrome.
The main clues to the presence of FAS are:
- Abnormal facial features, such as a smooth ridge between nose and upper lip.
- Lower than average height and weight.
- Problems affecting the central nervous system, such as small head size, difficulty paying attention, hyperactivity, and poor coordination.
- Alcoholic beverage consumption by the mother during pregnancy.
