Alcohol Use and Pregnancy and Fetal Alcohol Spectrum
Disorder
www.faseout.ca 2008
Alcohol is a Teratogen
• A teratogen is a substance that interferes with the normal development of the fetus
• Specifically, alcohol is a neurobehavioural teratogen – alcohol can damage the brain and change behaviour
www.faseout.ca 2008
Teratology:Four Outcomes to Exposure
• Malformations (facial, heart, skeletal)
• Growth Deficiency (small)
• Functional Deficits (learning and behavioural problems)
• Death (stillbirth, miscarriage)
www.faseout.ca 2008
Effects of Alcohol in Pregnancy
• Alcohol freely crosses the placenta
• Adverse effects to the fetus occur at levels at or below those that are toxic to women
• Fetal elimination of alcohol is poor
• Increased risk for low birth weight
• Harm can be caused before a woman knows she is pregnant
www.faseout.ca 2008
First Trimester
• First Month: heart, lungs, limbs, face, ears, eyes, spinal cord, and brain begin to form
• Second Month: toes and eyelids form and brain grows quickly and directs body’s movements
• Third Month: Most major organs and the face are developed. Bones continue to grow and kidneys start to work
www.faseout.ca 2008
Second Trimester
• Fourth Month: The placenta is fully formed and fetal movement may be felt by woman
• Fifth Month: Eyelashes, eyebrows and scalp and hair appear. Fetal heartbeat can be heard
• Sixth Month: Eyes open and close. Lungs, brain and other organs continue to develop
www.faseout.ca 2008
Third Trimester
• In the third trimester, the fetus grows quickly in weight and length
• Lungs and other major organs mature to support life
• The brain continues to grow and develop and remains vulnerable to the damage that alcohol can cause

Drinking in Perspective
In general women:
• may drink alcohol before they realize they’re pregnant
• may not know alcohol is harmful to the developing fetus
• may drink because it is the social/cultural norm
• may drink to self-medicate
www.faseout.ca 2008
No one can predict which infants born to mothers who drink will be affected, nor can anyone predict how severe these effects will be.
www.faseout.ca 2008
Factors Involved in FASD
• The stage in the pregnancy at which alcohol is consumed
• The amount of alcohol consumed during the pregnancy
• Other factors such as maternal age, stress, nutrition, smoking, and the use of other drugs (prescribed or street drugs)
• Fetal susceptibility to alcohol
www.faseout.ca 2008
Standard drinks = 0.5 oz alcohol12 oz (341 mL) can of beer (5% alcohol)
12 oz (341 mL) bottle of cooler (5% alcohol)
5 oz (142 mL) glass of wine (12% alcohol)
1.5 oz (43 mL) distilled spirits (40% alcohol)
3 oz (85 mL) fortified wine e.g. sherry or port (18% alcohol )
www.faseout.ca 2008
Paternal Role
• Effects on the Fetus: the effects of father’s drinking on the fetus are not fully known
• Effects on Pregnancy: Alcohol can result in lower sperm count and abnormal sperm, which may effect fertility. If alcohol-affected sperm does fertilize an egg, the likelihood of miscarriage is higher than if the sperm were not alcohol-affected
www.faseout.ca 2008
Paternal Role: Social Effects
• Women most often drink with their partners
• Men who drink heavily are unlikely to provide the necessary emotional support and care for their pregnant partners
• A man’s drinking after the baby is born could adversely affect the nurturing home environment needed to raise a child

What is Fetal Alcohol Spectrum Disorder?
www.faseout.ca 2008
Fetal Alcohol Spectrum Disorder (FASD)
• FASD is a combination of mental and physical disabilities
• FASD is a lifelong condition
• FASD is caused by maternal alcohol consumption during pregnancy
www.faseout.ca 2008
Diagnostic Terms
• Fetal Alcohol Syndrome (FAS)
• Partial Fetal Alcohol Effects (pFAS)
• Alcohol Related Neurodevelopmental Disorder (ARND)
• Alcohol Related Birth Defects (ARBD)
www.faseout.ca 2008
Fetal Alcohol Syndrome
Recognized and documented in Nantes, France and Seattle, Washington
1968 – 1973
www.faseout.ca 2008
Characteristics of FAS
• Facial anomalies
• Evidence of growth restriction (may be apparent prenatally and/or postnatally), (below the 10th percentile) and microcephaly
• Central nervous system abnormalities
www.faseout.ca 2008
FAS Features
www.faseout.ca 2008
ARND/pFAS: The invisible disability
• Physical characteristics FASD unremarkable
• Disappear: become less prominent over time
• Adolescent & Adult Diagnosis often more difficult
www.faseout.ca 2008
Alcohol-Related Neuro-Developmental Disorder (ARND)
• Individuals with ARND present with neuro-cognitive dysfunction and complex patterns of behaviour, and have a confirmed exposure to alcohol prenatally
• Individuals with ARND may not demonstrate any of the facial features or growth restrictions associated with the full syndrome
www.faseout.ca 2008
Partial Fetal Alcohol Syndrome (PFAS) with confirmed alcohol
exposure
This diagnostic term is used when the person presents with central nervous system dysfunction and most (but not all of the growth and/or facial features of FAS), and has a confirmed prenatal alcohol exposure
www.faseout.ca 2008
Diagnostic Process
• Information is collected regarding the individual – physical, social, academic, and adaptive skill history
• If possible, the physician, along with a psychologist and other specialists, will assess the individual in order to make an appropriate diagnosis
www.faseout.ca 2008
Possibility of Misdiagnosis
• Since FASD is not a mental health diagnosis, it might not be considered or recognized
• The symptom presentation of individuals with FASD is similar to that of many other mental health diagnoses
www.faseout.ca 2008
Possibility of Misdiagnosis
• Individuals may be diagnosed with a mental health disorder without closely examining the total picture
• Even when FASD is recognized, another diagnosis is often used in order to get reimbursement for treatment
www.faseout.ca 2008
Benefits to a diagnosis
Parents and professionals often find their ability to cope improves when they understand problems are most likely caused by brain damage not the person’s choice to be inattentive or uncooperative
www.faseout.ca 2008
Primary Disabilities
• Are the direct result of structural and/or functional damage to individuals
• While they can be evident in certain physical characteristics, it is the direct damage to the brain that has the greatest effect on the person
www.faseout.ca 2008
Primary Disabilities: Organ Anomalies
• Cardiac anomalies • Joint and limb anomalies• Neurotubal defects• Anomalies of the urogenital system • Hearing disorders• Visual problems• Severe dental malocclusions
www.faseout.ca 2008
Primary Disabilities: Central Nervous System
• Tremors
• Poor suck
• Hypotonic/Hypertonic
• Irritability
• Developmental delay
www.faseout.ca 2008
Primary Disabilities: Central Nervous System
• Cognitive problems
• Fine motor issues
• Hyperactivity
• Restlessness
• Poor ability to focus attention
www.faseout.ca 2008
Primary Disabilities
Generalized damage to the brain typically has a significant impact on:
• cognitive processing
• emotional regulation
www.faseout.ca 2008
Primary Disabilities: Central Nervous System
Cognitive problems
–Verbal IQ–Performance IQ–Scatter in Cognitive Skills–Specific Learning Disabilities–Memory Deficits–Executive Functioning

www.faseout.ca 2008
Primary Disabilities: Central Nervous System
• Poor Judgement
• Impulsiveness• Sleep disturbances • Extreme anxiety • Depression• Aggressiveness• Other Behavioural Problems

Executive functions ofthe prefrontal cortex
working memory
planning
time perception
internal ordering
self-monitoring
regulation of emotion
motivation
inhibition
www.faseout.ca 2008
Emotional Regulation
Emotional instability
For example, going from a calm to an agitated state (unexplained anger, laughing, crying) without apparent explanation
www.faseout.ca 2008
Emotional Regulation
• Deficits in emotional regulation are partly explained by poor inhibition and deficits in sensory integration (SI)
• Deficits in SI result in confusion in the interpretation of incoming sensations
• Individuals can become easily overwhelmed by relatively commonplace events/circumstances

Strategies Need to Address the Whole Being
Mental, physical, emotional,
spiritual and sexual well being
www.faseout.ca 2008
Strategies for Success
• Observe patterns of behaviour
• Identify strengths, skills and interests
• Reframe the interpretation of behaviours
• Provide structure rather than control
• Establish routines and consistency
www.faseout.ca 2008
Strategies for Success
• Build transitions into every routine
• Model behaviours
• Provide simple instructions or cues
• Identify behaviours which indicate the accumulation of frustration
• Help develop skills for expressing feelings
www.faseout.ca 2008
Strategies for Success
• Provide specific support for social skill development
• Understand the various forms of communication
• Include as many sensory modalities as possible to facilitate integration of information and experience
www.faseout.ca 2008
Strategies for Success
• Consider information processing abilities
• Re-evaluate expectations and goals for the individual: clarify whose needs are being met by the goals
• Clarify goals and values for education/job training and independence
