Fetal alcohol spectrum disorders (FASDs) are a group of conditions that can occur in a person whose mother drank alcohol during pregnancy. Symptoms can include an abnormal appearance, short height, low body weight, small head size, poor coordination, behaviorial problems, learning difficulties and problems with hearing or sight. Those affected are more likely to have trouble in school, legal problems, participate in high-risk activities and have problems with alcohol or other drugs. The most severe form of the condition is known as fetal alcohol syndrome (FAS). Other types include Partial Fetal Alcohol Syndrome (pFAS), Alcohol-Related Neurodevelopmental Disorder (ARND), Static Encephalopathy, Alcohol-Related Birth Defects (ARBD), and Neurobehavioral Disorder Associated With Prenatal Alcohol Exposure (ND-PAE). Some accept only FAS as a diagnosis, seeing the evidence as inconclusive with respect to other types.
