Alcohol is a recognized human teratogen that can produce FAS and a variety of alcohol-related effects. The fetal brain is particularly sensitive to alcohol during the period of rapid growth in the third trimester. After exposure, the cerebral cortex exhibits abnormal patterns in the distribution of neurons and abnormal neurotransmission. The hippocampus and cerebellum have decreased cell numbers and altered neurochemical activity. The corpus callosum appears to be absent or poorly developed in many children, as shown by MRI testing. The size and volume of the cerebellum and basal ganglia are reduced.
There are many long-term effects of FAS. The majority of children who have been followed into adulthood have problems leading independent lives. Many young adults who do not receive appropriate support are unable to maintain employment and relationships with family, friends and partners. Many have legal problems.
FASD
Fetal Alcohol Spectrum Disorders (FASD) is an umbrella term describing the range of effects that can occur in an individual whose mother drank alcohol during pregnancy. These effects may include physical, mental, behavioral, and/or learning disabilities with possible lifelong implications. The term FASD is not intended for use as a clinical diagnosis.
FASD covers other terms such as fetal alcohol syndrome, alcohol-related neurodevelopmental disorder (ARND), partial fetal alcohol syndrome (PFAS), alcohol-related birth defects (ARBD) and fetal alcohol effects (FAE). People affected by FASD can have brain damage; facial deformities; growth deficits; mental retardation; heart, lung and kidney defects; hyperactivity; attention and memory problems; poor coordination; behavioral problems; and learning disabilities.
