Fetal Alcohol Syndrome
Mary Rachel Bell
NSCI 5373
Why is it a Problem?
It is the leading cause of non-hereditary
mental retardation & number one cause of
mental retardation in the United States
One of the top three leading causes of birth
defects
Out of 1000 live births in the United States0.5 to 3.0 have FAS
Every year- over 40,000 babies are born with
some degree of alcohol-related effects in the
United States
Why is it a Problem?
One-third of babies born to mothers
who drink heavily during pregnancy
have FAS
Lifetime healthcare costs of a child born
with FAS in 2000 is estimated at
$588,000
History of FAS
First described in France in 1968
Described in United States by KL Jones
and DW Smith in 1973
Judges 13:3-4: “Behold, thou shalt
conceive and bear a son; and now drink
no wine or strong drink…”
Aristotle described children of foolish,
drunken women as foolish
Alcohol Consumption among
Pregnant Women on the Rise
Since 1991, the proportion of pregnant
women drinking at least one glass of
wine per day has quadrupled
Alcohol use among pregnant women:
1988-
22.5%
1992- 9.5%
1995- 15.3%
Alcohol Consumption
Recent survey on Babycenter.com
revealed :
51%
stopped drinking completely
30% still had a few sips
11% drank once per month
7% drank once per week
1% drank regularly- several times a week
4374 Participants
Alcohol Consumption among
Pregnant Women on the Rise
2000- 1 out of 29 pregnant women
report “risky” drinking
At
least half of these report “binge drinking”
Binge drinking- consuming more than five
drinks on one occasion
Type & extent of damage is due to pattern
& timing of maternal drinking
Diagnostic Criteria
Slow growth both before and after birth
Consistent pattern of minor structural
anomalies of the face, together with
more variable involvement of limbs and
heart
Deficient intellectual & social
performance, & muscular coordination
Deficient Growth
Involves height, weight & head
circumference
Children
with FAS grow taller at 60% of
normal rate through early childhood
Gain weight at 33% of normal rate
Therefore, FAS children may appear
malnourished
Decreased
head growth indicates
decreased brain growth
Structural Anomalies
Facial features
Small
eyes
Skin folds at corners of eyes
Flattened area between nose & upper lip
(flat philtrum)
Narrow upper lips
Short, small nose
May have drooping of eyes
Structural Anomalies
May have limitations of joint movement
May have deformities of small joints of the hands
May not be able to straighten fingers
May have incomplete elbow rotation
5 to 60 times more likely to get congenital
defects
More susceptible to ear infections
May lead to hearing loss
Reasons for these Anomalies
Alcohol causes premature cell death in
the bones & cartilage of the head & face
Alcohol intake decreases antioxidant
effects, so free radicals damage
mitochondria, which leads to cell death
Deficient Intellectual & Social
Performance
Half of all FAS patients have IQs less
than 70
Infancy:
Feeding
problems
Irritability
Unpredictable patterns of sleeping & eating
Decreases maternal bonding
Deficient Intellectual & Social
Performance
Preschoolers:
Very
active
Easily distracted
Poor fine motor coordination
Deficient Intellectual & Social
Performance
Elementary Children:
Often
diagnosed with ADHD
Increased activity level
Short attention span
Poor short-term memory
Poor communication skills
Speech difficulties
Difficulty
with social interactions
Deficient Intellectual & Social
Performance
Adolescents:
Poor
judgment
Depression
Trouble with abstract thinking
Limited problem-solving skills
Poor communication skills
Difficulty with social interactions- may
worsen as child ages
Reasons for Decreased
Intelligence
Alcohol interferes with nerve cell
development
Causes some regions to die off
Damage to gray & white matter
Failure of some regions to develop
Failure of some cells to migrate properly during
development
Affects left side of brain- like Down’s
Syndrome
Areas of the Brain Affected
Cerebellum
Smaller in FAS children
Due to tissue death
Responsible for movement & cognitive processessuch as attention
Basal Ganglia
Smaller in FAS children
Responsible for voluntary movement & cognitive
functions- such as perception, thinking, memory
Leads to Problems with…
Language
General intellectual functioning
Controlling precise movements
Attention problems
Impaired social functioning
Disturbed behaviors
Mental retardation
Psychiatric disorders
Psychiatric Disorders
94% had history of mental health
problems
61% had attention-deficit problems
52% of FAS adults had depression
Preschool & school-aged children show
autistic characteristics
Higher prevalence of eating disorders
Possible Nutrition Links
Mother may not consume enough
nutrients
Alcohol may impair placental transport
May receive less thiamin and folate due
to decreased intestinal absorption of the
mother, and due to decreased transport
across the placenta
Phillips et al
Possible Nutrition Links
Animal studies have shown alcohol intake
(acute and chronic) leads to the decreased
placental transfer of amino acids
Zinc Deficiency (Beattie)
Can occur in chronic alcoholics- zinc levels are
lower in alcoholic women
Associated with congenital malformations in
humans
Animal studies have revealed FAS-like anomalies
Studies have shown decreased zinc transport
across the placenta
Possible Nutrition Links
Glucose (Phillips et al)
Alcohol
impairs glucose placental transport
Alcohol impairs enzymes needed for fetus
to make glycogen
Glucose is needed for proper brain growth
May be why FAS babies have decreased brain
growth
Feeding FAS patient
Follow same rules as feeding mentally-
handicapped patient
Have set expectations at mealtime
Decrease distractions
Don’t
have television on during mealtime
Serve lots of finger foods
Feeding FAS Patient
Feed child several meals a day-
especially infants (increased needs)
May have sucking problems
May
try feeding spoon or cup
Be aware of possible development of
eating disorders among adolescents
Questions?!?!?
