Glossary

Fetal Alcohol Spectrum Disorder (FASD)

An umbrella term that describes a continuum of conditions that result from prenatal alcohol exposure. FASD is not a diagnostic term.


The specific diagnoses within the spectrum include*:

Fetal Alcohol Syndrome (FAS) with Confirmed Maternal Alcohol Exposure

Diagnostic criteria include: Confirmed prenatal alcohol exposure, the presence of all 3 characteristic facial features (short palpebral fissures, smooth philtrum, thin upper lip), growth deficiency, and evidence of impairment in 3 or more of the following central nervous system (CNS) domains: hard and soft neurologic signs; brain structure; cognition,; communication; academic achievement; memory; executive functioning and abstract reasoning; attention deficit/hyperactivity; and adaptive behaviour, social skills and social communication.


FAS without Confirmed Maternal Alcohol Exposure

The diagnostic criteria are the same as above however the presence of prenatal alcohol exposure is unconfirmed.


Partial Fetal Alcohol Syndrome (pFAS)

The diagnostic criteria include: Confirmed prenatal alcohol exposure, the presence of 2 of the characteristic facial features, and evidence of CNS impairment as above.


Alcohol Related Neurodevelopmental Disorder (ARND)

The diagnostic criteria include: Confirmed prenatal alcohol exposure and evidence of CNS impairment as above.


Alcohol Related Birth Defects (ARBD)

This term should not be used as an umbrella term or diagnostic term. ARBD constitutes a list of congenital anomalies including malformations and dysplasias and should be used with caution.



Fetal Alcohol Effect (FAE)

FAE was a term formerly used to describe the impairment to a child exposed to alcohol prenatally, however the impairment was not sufficient to satisfy the criteria for a diagnosis of FAS.
