Fetal Alcohol Syndrome (FAS) is a preventable condition that occurs when a fetus is exposed to alcohol in the womb, causing problems with learning, behaviour, and mental and physical health that can last throughout a person's life. While there is no specific medical test for FAS, diagnosis in adults is similar to diagnosis in children, and a doctor may refer a person for a neuropsychological assessment. This assessment will consider various factors, including abnormal facial features, growth deficits, neurological and behavioural characteristics, and the presence of other health conditions such as bone and joint problems, kidney and liver issues, and mental health concerns.
| Characteristics | Values |
|---|---|
| Facial features | Abnormal facial features, such as a smooth philtrum |
| Growth | Restricted growth, including height and head size |
| Neurological aspects | Brain abnormalities, problems with attention, distraction, learning and memory |
| Behavioral aspects | Problems with behaviour, internalizing problems such as depression, anxiety, social anxiety and obsessive-compulsive disorder |

Neuropsychological assessment
The neuropsychological assessment aims to evaluate the cognitive and behavioural consequences of prenatal alcohol exposure. This includes assessing overall intellectual performance, executive function, learning and memory, language, visual-spatial ability, motor function, attention, and activity levels. The assessment also considers behavioural problems, such as adaptive dysfunction, academic difficulties, and increased rates of psychiatric disorders.
The diagnostic process for FASDs involves a multidisciplinary approach, including medical evaluations and neurodevelopmental assessments. The neurodevelopmental assessment process may include specific tests such as the Beery-Buktenica Developmental Test of Visual-Motor Integration, the Brief Visuospatial Memory Test, and the Auditory Comprehension Test. These tests help identify neurobehavioural deficits and provide a comprehensive understanding of the individual's neuropsychological status.
Additionally, the assessment team must explore other possible explanations for the observed deficits, including genetic or medical conditions, developmental level, familial background, and environmental factors. This "differential diagnosis" approach helps rule out other potential causes of the individual's symptoms. Ultimately, the diagnosis of FASDs relies significantly on evidence of a history of maternal alcohol use during pregnancy.
It is important to note that the diagnostic guidelines for FASDs may vary internationally, and there is ongoing development in this field to improve the accuracy and specificity of recommendations, criteria, and clinical cut-offs.

Multidisciplinary team evaluation
A multidisciplinary team evaluation is crucial for diagnosing Fetal Alcohol Spectrum Disorder (FASD) in adults, as it involves a comprehensive assessment of various factors and symptoms. This evaluation process typically includes medical professionals from different specialties, such as family physicians, obstetricians, pediatricians, geneticists, and psychiatrists and psychologists.
The multidisciplinary team approach ensures that FASD diagnosis is not made in isolation by a single healthcare provider. Primary care providers play a crucial role in recognizing the signs and symptoms of FASD and making appropriate referrals for further evaluation and management. They should keep FASD in their differential diagnosis and collaborate with specialists to ensure accurate diagnosis and comprehensive care.
The evaluation process typically involves a physical examination, a neurobehavioral assessment, and a review of the patient's medical history. The physical examination focuses on identifying any growth deficiencies, facial features associated with FASD, and other physical abnormalities. The neurobehavioral assessment evaluates cognitive, behavioral, and neurodevelopmental impairments, including learning difficulties, impulsivity, and problems with social integration and independent living.
Additionally, the multidisciplinary team will consider the patient's history of prenatal alcohol exposure, which is a critical factor in FASD diagnosis. Confirmation of prenatal alcohol exposure is not always required, especially if the individual exhibits other characteristic features of FASD. However, a detailed understanding of the patient's medical history, including maternal alcohol consumption during pregnancy, can aid in the diagnostic process and guide appropriate interventions.
In some cases, early childhood photographs may be necessary to confirm the diagnosis, as the facial characteristics associated with FASD may become less pronounced in adulthood. The evaluation may also include assessments of the patient's neuroanatomy, neurophysiology, and motor skills, as alcohol exposure during pregnancy can impact the development of the brain and other critical organs.

Facial features and growth analysis
Facial analysis is a critical component of diagnosing Fetal Alcohol Syndrome (FAS) in adults. While there is no single medical test for FAS, healthcare professionals rely on a combination of interviews, examinations, and medical tests to make a diagnosis. Facial features are one of the key indicators of FAS, and they can help distinguish it from other syndromes and disorders.
Abnormal facial features are often a tell-tale sign of FAS. These may include a smooth philtrum, small eye openings, a thin upper lip, and a short nose. These features are indicative of the growth deficits associated with FAS. In addition, the eyes may appear small, and the ears may be malformed or misshapen. The mouth area may also be affected, with the upper lip appearing thin, and the philtrum, which is the groove between the nose and the upper lip, appearing smooth or flattened.
When evaluating an adult for FAS, healthcare professionals will carefully examine these facial characteristics. They may use specialised tools and techniques, such as dysmorphology assessments, to analyse the facial features in detail. This involves measuring and comparing the proportions of the facial features to identify any abnormalities.
In addition to the physical characteristics, the timing of growth and development is also considered during the diagnostic process. Adults with FAS may have experienced growth deficits, resulting in shorter stature or smaller head circumference. Growth charts and developmental milestones can provide valuable information about the individual's growth pattern and whether it aligns with the typical trajectory associated with FAS.
While facial features and growth analysis are crucial aspects of diagnosing FAS in adults, they should be considered alongside other factors, including neurological and behavioural characteristics, as well as the individual's medical history and exposure to alcohol during pregnancy. A multidisciplinary team, including a dysmorphologist, clinical geneticist, and mental health professional, may be involved in the evaluation to ensure a comprehensive assessment and accurate diagnosis.

Educational and vocational assessment
When diagnosing fetal alcohol syndrome (FAS) in adults, there is no single medical test available. Instead, a combination of interviews, examinations, and medical tests are used by healthcare professionals. An FAS evaluation may include a review of medical history, behavioural assessments, physical examinations, and genetic testing.
The assessment process may include gathering information on an individual's school reports and academic achievements, as well as any difficulties they experienced in a learning environment. This can include problems with attention, memory, learning, and internalizing issues such as anxiety or depression. By understanding the specific educational challenges, healthcare professionals can tailor interventions and provide the necessary support to improve the individual's overall functioning.
Vocationally, the assessment may explore an individual's employment history and job performance, along with any difficulties they have encountered in the workplace. Adults with FAS may struggle with various aspects of employment, including learning new skills, adapting to routines, and interacting with colleagues. Understanding these challenges is essential to develop strategies that can enhance their vocational capabilities and overall job satisfaction.
The results of the educational and vocational assessment, along with other evaluations, contribute to the diagnosis of FASD and help healthcare professionals create personalized treatment plans. These plans may include behavioural interventions, educational support, and medical management tailored to the unique needs of the individual. The goal is to empower them to succeed in their educational pursuits and achieve meaningful vocational opportunities.

Medical tests and interviews
Diagnosing Fetal Alcohol Syndrome (FAS) in adults can be challenging due to the lack of a direct medical test. However, medical professionals employ various methods to make an accurate diagnosis. Here are the key components of medical tests and interviews used in the diagnosis of FAS in adults:
Medical History Review
This involves evaluating the individual's medical records, including prenatal care records, to identify potential risk factors or exposures during pregnancy. Information about the birth parent's alcohol consumption during pregnancy is crucial for this assessment.
Developmental and Behavioral Assessments
These assessments observe and test cognitive abilities, motor skills, language development, and behavior. They help evaluate any learning, attention, communication, or behavioral difficulties the individual may be experiencing.
Physical Examination
The physical examination checks for characteristic facial abnormalities associated with FAS, such as a smooth connection between the nose and upper lip, a thin upper lip, and small eyes. It also assesses growth deficiencies, including smaller-than-expected head size and height.
Neurological Assessment
This evaluation focuses on brain function, including reflexes, coordination, and sensory processing. It helps identify any central nervous system problems, such as problems with attention, hyperactivity, or poor coordination.
Interviews with Parents or Caregivers
Gathering information from parents or caregivers about the individual's early development, behavior, and exposure to alcohol during pregnancy is essential. It provides valuable insights into the individual's history and potential prenatal alcohol exposure.
Educational and Vocational Assessment
For adults, assessing educational and vocational history helps understand their current functioning and support needs. It provides context for any learning or behavioral difficulties they may have experienced and continues to experience.
It is important to note that FAS diagnosis in adults may also involve referring individuals to specialists, such as pediatricians, psychiatrists, or psychologists, for further assessments and evaluations. While there is no single diagnostic test, combining these evaluations and interviews helps healthcare professionals make an accurate FAS diagnosis and develop tailored treatment plans.
