Fetal Alcohol Spectrum Disorder (FASD) is a preventable disorder caused by maternal alcohol consumption during pregnancy, leading to a range of physical and neurodevelopmental problems in the child. The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) is a publication by the American Psychiatric Association (APA) that aims to standardize diagnostic criteria and terminology for behavioral health conditions. The inclusion of Fetal Alcohol Syndrome (FAS) and its related conditions in the DSM-5 has been a subject of debate due to the lack of consensus on diagnostic criteria and terminology. While FASD is not intended for use as a clinical diagnosis, the DSM-5 introduced the term Neurodevelopmental Disorder Associated with Prenatal Alcohol Exposure (ND-PAE) to encompass the spectrum of psychiatric, behavioral, and neurological symptoms associated with prenatal alcohol exposure. This term is included in the DSM-5 as a condition for further study and as a specifier for intellectual disability. The inclusion of ND-PAE in the DSM-5 provides a diagnostic code for individuals exposed prenatally to alcohol and experiencing neurodevelopmental deficits, contributing to a better understanding and management of FASD.

What You'll Learn
Fetal Alcohol Spectrum Disorder (FASD)
The several forms of the condition, in order of most to least severe, are: Fetal Alcohol Syndrome (FAS), Partial Fetal Alcohol Syndrome (pFAS), Alcohol-Related Neurodevelopmental Disorder (ARND), and Neurobehavioral Disorder Associated with Prenatal Alcohol Exposure (ND-PAE). FASD also encompasses other terms such as Fetal Alcohol Effects (FAE), Partial Fetal Alcohol Effects (PFAE), Alcohol-Related Birth Defects (ARBD), and static encephalopathy, although these terms are no longer considered part of the spectrum.
The key signs of FAS required for diagnosis include growth deficiency, congenital malformations of the lips, nervous system damage, small eye openings, and an abnormally increased distance between the eyes. Other FASD conditions are partial expressions of FAS, where the central nervous system shows clinical deficits. People with FAS often have a hard time in school and trouble getting along with others. Those with ARND might have intellectual disabilities and problems with behaviour and learning, and may struggle with math, memory, attention, judgment, and impulse control.
The inclusion of FAS and its associated conditions in the DSM-5 has long been a contentious issue due to a lack of consensus on diagnostic criteria and terminology. ND-PAE was introduced into the DSM-5 in 2013 as a condition for further study and a specifier for intellectual disability. It is included in the appendix and used as an example for "Other Specified Neurodevelopmental Disorder". The DSM-5 criteria emphasise psychometric measurements over features that might be attributed to familial genetics.

Fetal Alcohol Syndrome (FAS)
Fetal Alcohol Spectrum Disorder (FASD) is an umbrella term for a group of preventable conditions that can occur in a person exposed to alcohol before birth. The several forms of the condition, in order of most to least severe, are: Fetal Alcohol Syndrome (FAS), partial fetal alcohol syndrome (pFAS), alcohol-related neurodevelopmental disorder (ARND), and neurobehavioral disorder associated with prenatal alcohol exposure (ND-PAE). FAS is the most severe form of FASD and is characterised by central nervous system (CNS) problems, minor facial features, and growth problems.
The original description of FAS, established in the early 1970s, included growth failure, intellectual disability, and characteristic changes in facial structure. However, as understanding of the effects of prenatal alcohol exposure grew, it became clear that the clinical presentation of FAS was not as straightforward as previously thought. This led to the emergence of the term "fetal alcohol effects" (FAE), which described children whose behaviour and cognitive functioning had been affected by prenatal alcohol exposure but whose growth and facial features were normal.
The inclusion of FAS and its associated conditions in the DSM-5 has been a contentious issue due to a lack of consensus on diagnostic criteria and terminology. ND-PAE was introduced in the DSM-5 as a "condition for further study" and as a specified condition under "other specified neurodevelopmental disorders". The DSM-5 criteria emphasise psychometric measurements over features that might be attributed to familial genetics, such as head circumference, facial dysmorphic features, and body length and weight. However, the criteria are not yet validated and there is still a lack of standardisation in diagnostic tools for FASD.
The diagnosis of FASD and its various forms, including FAS, typically involves a physical examination, the creation of a differential diagnosis, a neurobehavioural assessment, treatment, and follow-up. The diagnostic process requires a multidisciplinary approach and can include clinical assessment tools, neurodevelopmental screening, and a sensitive exploration of a history of prenatal alcohol exposure.

Partial Fetal Alcohol Syndrome (pFAS)
Fetal Alcohol Spectrum Disorder (FASD) is a preventable disorder caused by maternal alcohol consumption during pregnancy, resulting in a range of physical and mental disabilities for the child. The disorder is marked by a broad spectrum of clinical deficits related to prenatal alcohol exposure, with the severity of the condition varying from mild to severe.
The inclusion of FAS and its associated conditions in the DSM-5 has been a contentious issue due to a lack of consensus on diagnostic criteria and terminology. While ND-PAE (Neurodevelopmental Disorder Associated with Prenatal Alcohol Exposure) is mentioned in the DSM-5 under 'Other Specified Neurodevelopmental Disorder', it is included as a condition requiring further study and no diagnostic criteria or detailed description is provided. This means that while there is now a diagnostic code for children, youth, and adults exposed prenatally to alcohol and presenting neurodevelopmental deficits associated with alcohol toxicity, ND-PAE itself is not a recognised diagnosis.
The lack of standardisation in diagnostic tools for FASD has led to variability in research findings, inconsistencies in government messaging, and issues with misdiagnosis and missed diagnoses. The objective measurement of the timing and level of prenatal alcohol exposure is key to addressing these issues, but there is currently conflicting or limited evidence to support this.

Alcohol-Related Neurodevelopmental Disorder (ARND)
Fetal Alcohol Spectrum Disorder (FASD) is a preventable disorder caused by maternal alcohol consumption during pregnancy, leading to a range of physical and mental disabilities. FASD encompasses a broad continuum of clinical deficits, with Fetal Alcohol Syndrome (FAS) being the most severe form. The original description of FAS, established in the early 1970s, included growth failure, intellectual disability, and changes in facial structure. However, as understanding of the disorder evolved, it became clear that the clinical presentation could vary significantly. This led to the introduction of the term "fetal alcohol effects" to describe cases where cognitive functioning and behavior were affected, but growth and facial features appeared normal.
The American Psychiatric Association (APA) has attempted to address the lack of clarity and consistency in diagnosing less severe forms of FASD by introducing new terminology and diagnostic criteria in the fifth edition of its Diagnostic and Statistical Manual (DSM-5). The DSM-5 diagnosis "Neurodevelopmental Disorder Associated with Prenatal Alcohol Exposure" (ND-PAE) acknowledges the range of neuro-disabilities associated with prenatal alcohol exposure, regardless of the presence or absence of physical effects. However, ND-PAE is not listed as a separate diagnosis in the DSM-5 but is included in the appendix as a condition requiring further study.
The diagnosis of ARND is made after birth, as prenatal scans cannot detect FAS or FASDs. Confirmation of maternal alcohol consumption during pregnancy is required for diagnosis. Early diagnosis is crucial for managing symptoms and preventing secondary conditions, such as mental health issues. To prevent ARND, it is essential for individuals who are pregnant or planning to become pregnant to avoid alcohol consumption.

Diagnostic criteria
Fetal Alcohol Spectrum Disorder (FASD) is a group of conditions that can occur in a person exposed to alcohol before birth. FASD encompasses Fetal Alcohol Syndrome (FAS), Partial Fetal Alcohol Syndrome (PFAS), Alcohol-Related Neurodevelopmental Disorder (ARND), and Alcohol-Related Birth Defects (ARBD). FASD can result in a range of neuro-disabilities, including intellectual disability, behavioural problems, and physical abnormalities.
The inclusion of FASD in the Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5) has been a contentious issue due to the lack of standardisation in diagnostic criteria across different systems. However, the DSM-5 has incorporated new terminology and diagnostic criteria to address this lack of clarity and consistency, particularly for less severe forms of FASD.
The DSM-5 introduced the term "Neurodevelopmental Disorder-Prenatal Alcohol Exposure" (ND-PAE) to describe the range of neuro-disabilities associated with prenatal alcohol exposure. ND-PAE is included in the DSM-5 as a condition for further study and is listed under "Other Specified Neurodevelopmental Disorder". While ND-PAE does not have specific diagnostic criteria in the DSM-5, it provides a diagnostic code and triggers access to services and interventions for individuals with neurodevelopmental deficits associated with prenatal alcohol exposure.
The diagnostic criteria for ND-PAE emphasise the measurement and observation of neurocognitive impairments rather than the presence of dysmorphic physical symptoms. Confirmation of maternal alcohol consumption beyond minimal levels is required, typically defined as more than 13 alcoholic drinks per month of pregnancy or more than 2 alcoholic drinks in one sitting. The presence of cardinal dysmorphic facial features associated with FAS may also be assessed during the physical examination.
The diagnostic process for FASD involves a multidisciplinary approach, including a physical examination, differential diagnosis, neurobehavioural assessment, treatment, and follow-up. Clinicians are urged to assess and note any growth issues, but growth restrictions are not included as a diagnostic criterion. An "at-risk" category has been proposed for individuals who do not meet the full criteria for FASD but have prenatal alcohol exposure and related issues.

Frequently asked questions
Fetal Alcohol Syndrome (FAS) is a preventable disorder caused by maternal alcohol consumption during pregnancy. It is marked by a range of physical and mental disabilities, including growth deficiency, intellectual disability, nervous system damage, and characteristic changes in facial structure.
The DSM-5 is the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders published by the American Psychiatric Association (APA). It provides standardised diagnostic criteria and a common language for defining and coding mental health conditions affecting individuals across the lifespan.
Fetal Alcohol Spectrum Disorder (FASD), an umbrella term encompassing all disorders related to prenatal alcohol exposure, is recognised in the DSM-5. However, there is no specific diagnostic code for FAS within the manual.
While FAS is not specifically listed in the DSM-5, the related condition "Neurodevelopmental Disorder Associated with Prenatal Alcohol Exposure" (ND-PAE) is included under "Other Specified Neurodevelopmental Disorder" as a condition requiring further study. This diagnostic code allows for the recognition and diagnosis of neurodevelopmental deficits associated with prenatal alcohol exposure.
The key signs required for a diagnosis of FAS include growth deficiency, congenital malformations of the lips, nervous system damage, small eye openings, and abnormal facial features such as a smooth ridge between the nose and upper lip (philtrum). Individuals with FAS may also experience problems with learning, memory, attention, communication, and social interactions.
