Partial Fetal Alcohol Syndrome-is a medical diagnosis used to describe an individual born with permanent brain damage and two of the three facial birth defects found in FAS. Confirmation of maternal alcohol use in pregnancy is required for this relatively uncommon diagnosis.

the primary effects of FASD are those resultant behaviours that most clearly reflect the brain damage caused by the use of alcohol in pregnancy. For example: an inability to effectively use mathematical, time or money concepts.
