FASD are a spectrum of disorders linked to prenatal exposure to alcohol including
Alcohol Related Birth Defects (ARBD) Heart and kidney anomalies
Fetal Alcohol Syndrome (FAS) Pathognomonic cluster of
Growth impairment (<10th centile) Small palpebral fissures Thin upper lip Smooth philtrum Cognitive impairment
Partial Fetal Alcohol Syndrome (pFAS) Some facial features associated with severe impairment in 3 domains of
brain function in the presence of prenatal alcohol exposure
Alcohol Related Neurodevelopmental Disorder (ARND) Severe impairment in 3 domains of brain function in the presence of
confirmed prenatal alcohol exposure
Alcohol is a teratogen (Uban et al C5 p73-108 in FASD-management and Policy perpsectives of FASD 2011 Wiley)
Readily crosses placenta and blood-brain barrier
Directly affects fetal growth and development (animal models)
Delays developmental processes and tissue differentiation eg cell division
Affects DNA and protein production esp in hippocampus, amygdala and cerebellum
Disrupts stem cell proliferation- neurons and glial cells
Apoptosis (programmed cell death) increased
Disorganises cortical architecture
Alcohol is a teratogen (Uban et al C5 p73-108 in FASD-management and Policy perspectives of FASD 2011 Wiley)
Indirectly affects fetus
Associated nutritional deficiencies (calories, protein, zinc, folate, vitamin A)
Abnormal calcium signalling
Altered prostaglandin interactions
Placental dysfunction
Interference with growth factors mediating cell proliferation, growth, differentiation and maturation
Oxidative and free radical damage
Disrupted endocrine balance- hypothalamic pituitary axis
Why diagnose FASD?Good question… We have no firm idea how
much of it there is especially in NZ
We can’t fix it
We have very few teams set up to evaluate it
We have no services specifically to support families
We have no education services primed to respond
Diagnosis is made complex due to comorbid conditions and other developmental confounders
Other prenatal risk factors-P, cigarettes, poor maternal nutrition
Post natal environment-abuse , neglect, attachment
Diagnose FASD because Preventable
Likely very common
FASD are a result of brain damage which increase vulnerability to other stressors. FASD is a disability
Secondary disability is reduced with intervention
Social cost is significant and reduced with intervention
Specific assessment and support services are needed
We have to start somewhere

FASD is preventable Children who have not
been exposed to alcohol prenatally do not get FASD
There is no safe amount of alcohol in pregnancy nor safe time to drink
Prenatal alcohol exposure does not always result in FASD (Warren & Foudin 2001)
So why doesn’t everyone get FASD?
Risk factors influencing FASD Alcohol’s teratogenic effect can be moderated or
exacerbated Twin discordance (Warren & Li 2005; Streissguth & Dehaene,1993)
Amount of alcohol consumed in pregnancy and duration strongly linked to severity of FASD (Bonthius &West 1988; Maier, Chen & West 1996) but not a tidy linear relationship
Binge drinking more damaging than chronic exposure (Bonthius, Goodlett &
West 1988)
Higher risk of FASD with binge drinking than chronic exposure (Maier &
West 2001)
Risk factors influencing FASD Critical periods in fetal development influence type of
brain damage
Range of phenotype across FASD (Bertrand et al 2001)
QFT: Quantity, Frequency, Timing
Facial development week 3-4 post conception (day 19-21) (Sulik 2005)
Proliferation, migration and differentiation of cerebral cortex precursor cells in first trimester blocked by alcohol (Miller 1996) versus myelinisation occurring later
3rd trimester specific structures developing- hippocampus, cerebellum, prefrontal cortex (Livy et al 2003)

Risk Factors influencing FASD Genetic factors
Influencing maternal alcohol metabolism (McCarver et al 1997)
Epigenetics (Haycock 2009)
Environmental factors
Prenatal care & nutrition (Morgan & Levine 1988)
Poly substance abuse, maternal age, ethnicity, socioeconomic status (Warren & Foudin 2001)
Post natal environment
Child maltreatment (Oppenheim & Goldsmith 2007)

Drinking in pregnancy (O’Keeffe et al BMJ 2015)
Prevalence and predictors of alcohol use during pregnancy
Multicentre cohort of 18000 from Ireland, UK, NZ and Australia
40-80% reported alcohol exposure in pregnancy (excl Ireland)
All social groups drinking
Less drinking with higher socioeconomic status, having other children, being overweight or obese
Caucasian more likely to drink than other ethnicities
Younger women less likely to drink than older (30-39yrs)
Heightened drinking with smoking
Growing up in NZ (Social Policy Evaluation and Research Unit, 2015)
6800 expectant mothers from GUiNZ study asked to recall alcohol consumption in pregnancy
29% complete abstention (Pacific/Asian/low income/disadvantaged)
43% stopped once they knew and then abstained (European/advantaged)
16% stopped after 1st trimester (younger/ Maori/disadvantaged)
9% stopped and started (European/advantaged)
2% drank continuously at least 1 drink /week (older /Maori/ disadvantaged/ smokers)
Drinking unrelated to whether pregnancy planned
Don’t know? Don’t drink.
Whilst there is awareness of the risk of drinking in pregnancy broadly
We adjust the message to the one we want to hear
There is a disconnect about the period before you know you are pregnant

USA - 0.5-2.0/1000 births (May & Gossage 2001)
South Africa Cape Coloured community – 46.4/1000 births (May et al 2000)
Canada – 0.52-14.8/1000 births (Habbick et al 1996, Williams, Odaibo & McGee 1999)
FASD estimates Canada – 9/1000 births (Health Canada 2006)
USA – in school case ascertainment study 2-5/100 (May et al 2009)
Guestimate in NZ 10 in a 1000 births?
Compare to Down syndrome: 1/1000 (CDC 2015)
Autism: 4/1000 (Baird et al 2006)
Cerebral Palsy: 1.5-4/1000 (CDC 2015)

Modify you approach if the child has FASD Do you work with parents or child or both?
Can you used a language based intervention or do you need to approach it differently?
How can you prevent the child being put in situations they can’t handle?
Supervision (what do the family understand by that)
How do you support them and advocate for them if they do get traumatised or involved with Youth Justice?
FASD specific interventions Need to take into account the differences between brain
injury caused behaviour and attention problems and those caused by attachment or trauma.
Brain damage reduces resilience and impedes recovery from trauma
Treatment approaches need to accommodate the individual brain differences

Hawke’s Bay experience Started recognising FASD
Took training opportunity (Thanks to Alcohol HealthWatch)
Decided FASD was just part of what we do- not new- just not done properly before
Put assessment pathway together (HPA website)
Communicated with our community (a lot)
Continuous service development
FASD education (2 modules)

Process evaluation looking our team’s strengths and challenges Lots of positives but you learn and develop by looking at the challenges
Challenges Waitlist
Lack of post-assessment support for the FASD assessment pathway
Complexity/ length of reports
Maintaining the team
Disconnect between Health and Education approaches
Engaging families
Cultural responsiveness
On the horizon DSM-V: Neurodevelopmental Disorder associated with
prenatal alcohol exposure
New Canadian Guidelines (imminent)
National FASD Action Plan (MoH)
Need for NZ prevalence data to drive service provision
Need to look at interventions that would work well in the NZ context
