Fetal Alcohol Syndrome
Alcohol is a teratogen. A teratogen is an agent that can cause
malformations of an embryo or fetus. Continuous heavy drinking
during pregnancy causes Fetal Alcohol Syndrome (FAS). FAS is the
number one recognized cause of mental retardation. When
expectant mothers drink during their pregnancy, the alcohol
carries to all organs, tissues, and passes through membrane and
fetal blood systems. Because of this, the alcohol goes straight
to the fetus and all its developing tissues and organs. The
amount of alcohol concentration in the fetus is the same amount,
or sometimes more, as the mothers'. The liver of an adult can
process alcohol at the rate of one ounce every two hours, while
the liver of the fetus is not able to process alcohol as
quickly. Sometimes it takes nearly twenty-four hours.
Not all women who drink during their pregnancy give birth to
children with FAS, even those who drank frequently. Some child
that are born to alcoholic mothers appear to be normal as an
infant but develop physical, intellectual, and psychological
problems as they grow older, due to exposure of alcohol as a
fetus. According to most studies, there is no such thing as a
safe amount of alcohol consumption.
The effects of alcohol on the infant vary in each trimester. The
first trimester is the most critical stage. The earlier the
exposure, the greater the risk for FAS. In the second trimester,
miscarriage is a huge risk. In the third trimester, the fetus
normally experiences rapid growth and substantial growth. The
mother's consumption of alcohol could impair the infant's
growth. This is also the time where the most important part of
the brain development occurs. According to research, the brain
and central nervous are at the greatest risk during the third
trimester.
Children born with Fetal Alcohol Syndrome develop symptoms such
as: low birth weight, small head size, narrow eye slits, flat
midface, low nasal ridge, loss of groove between nose and upper
lip, muscle problems, bone and joint problems, genital defects,
heart defects, and kidney defects.
In addition to physical handicaps, FAS also affects the central
nervous system. The child develops symptoms such as mental
retardation, alcohol withdrawal at birth, poor sucking response;
sleep disturbances, restlessness, irritability, and learning
disabilities.
FAS also affects the child's behavior, causing behavioral
impairments. One of the behavior traits effect by FAS is the
child's verbal learning. The child has difficulty with language
and memory. Studies showed that children and teens with FAS
learned fewer words than normal, but were able to recall
information learned. FAS-related learning problems happen during
the initial stages of memory formation. Once the formation is
finished, verbal information can be remembered and subject to
normal rates of forgetting. This helps distinguish FAS from Down
syndrome.
Another behavioral trait affected by FAS is visual-spatial
learning. The child does poor on learning spatial abilities. For
example if the child were to remove an object from somewhere, he
would have great difficulty putting the object back to its
original place.
The next behavioral impairment is attention. Attention problems
happen most often because of prenatal exposure. In several
cases, FAS is often mistaken for attention defect hyperactivity
disorder (ADHD) and treated incorrectly. Children with ADHD have
difficulty focusing and sustaining attention over a certain
period, while children with FAS have difficulty moving their
attention from one task to another.
The child processes information slower than the average child
does. The brain processes slower, less efficient information.
Not all children with FAS have mental retardation. A recent
study showed that sixty-one adolescents and adults with FAS
revealed IQ scores with a range of 20 to 105 with an average of
68. Fifty-eight percent of these individuals had an IQ score of
seventy or below.
There is no cure for Fetal Alcohol Syndrome, but the question
is, Can it be treated? Birth defects related to alcohol use are
permanent. Surgery can repair some of the physical problems, and
school programs can improve mental and physical developments.
How can FAS be prevented? Research has shown that pregnant women
will reduce or cease their alcohol consumption if they are made
aware of the harmful effects of alcohol on their infants.
However, the best way to avoid fetal alcohol syndrome is not to
drink alcohol during any part of the pregnancy. Even small
amounts of alcohol can cause FAS.
