1) Disease Description (Causes and Symptoms)
- Definition summary: Fetal alcohol syndrome (FAS) is a form of congenital malformation and neurodevelopmental disorder that occurs in the fetus due to maternal alcohol exposure during pregnancy and belongs to the category of fetal alcohol spectrum disorders (FASD).
- Cause: Alcohol consumption during pregnancy (maternal drinking) is the main cause. Alcohol crosses the placenta and directly causes toxicity to the fetus. Because a safe amount of alcohol consumption during pregnancy (a harmless lower limit) has not been established, the recommendation is complete abstinence.
- Pathophysiology (brief): Alcohol and its metabolite (acetaldehyde) interfere with fetal cell proliferation, neuronal migration, and synapse formation, and induce oxidative stress and apoptosis, resulting in central nervous system abnormalities and malformations.
- Main clinical symptoms
- Appearance: Short stature and low body weight (prenatal and postnatal growth retardation), characteristic facial features (short palpebral fissures, smooth philtrum, thin upper lip)
- Neurodevelopment: Intellectual disability, learning disabilities, attention-deficit/hyperactivity disorder (ADHD) features, impulsivity, executive function disorder, and problems with social communication
- Associated malformations: Congenital heart defects (such as ventricular septal defect), spinal and limb malformations, and visual and hearing abnormalities
2) Treatment Methods and Precautions
- Treatment principles: There is no fundamental cure. Symptom-specific, multidisciplinary support (including pediatrics, neurology, cardiology, ophthalmology, otolaryngology, psychology, and educational rehabilitation) and early intervention improve the prognosis.
- Specific treatments and interventions
- Early intervention programs (developmental therapy, speech therapy, physical therapy, and occupational therapy)
- Educational support (special education classes and individualized education plans)
- Behavioral and psychological therapy (behavior modification and parent education)
- Pharmacological treatment: Selective use according to symptoms such as comorbid ADHD, depression, anxiety, and sleep disorders (e.g., ADHD medications and antidepressants) — medication selection and monitoring require a specialist
- Correction of malformations: Surgical or medical treatment for structural heart disease, ophthalmic problems, and other conditions
- Family and social support: Caregiver education and coordination with local welfare services and schools
- Precautions and risk of complications
- Early diagnosis is important for the prognosis. Learning and behavioral problems accumulate as diagnosis is delayed.
- Testing is needed to differentiate other causes of malformations besides alcohol, such as chromosomal abnormalities.
- Long-term risks include mental health problems (depression, anxiety, and substance abuse), academic and social difficulties, and legal problems.
- Precautions for self-management
- Abstinence is recommended for women who are planning a pregnancy or are of childbearing age.
- Use a consistent environment (rules and predictable routines) and positive reinforcement for the child’s behavioral and learning problems.
3) Checklist Before an Outpatient Visit (Materials to Prepare and Example Questions)
- Materials and information
- The mother’s pregnancy and delivery records (if possible, including specific details of alcohol use during pregnancy, such as the timing and amount)
- The child’s growth chart (including birth weight and height) and previous medical records
- A list of medications, vitamins, and supplements currently being taken
- Previous test results (such as echocardiography, brain imaging, and genetic testing) and vaccination records
- School evaluation reports and psychological test results (cognitive tests and behavioral assessments), if available
- Family history (intellectual disability, mental illness, and congenital malformations)
- Example questions to ask the doctor during an outpatient visit (related to diagnosis and evaluation)
- “What tests will be performed during this visit? (Echocardiography, hearing test, vision test, neurodevelopmental assessment, etc.)”
- “What information is needed to evaluate the child’s behavioral and learning problems?”
4) Examples of General Questions to Ask the Doctor
- What are the expected benefits and major side effects of this medication (or treatment)?
- What is the expected long-term prognosis for our child (learning and social functioning)?
- What management methods can parents implement in daily life (such as routines and discipline methods)?
- What additional tests or specialist consultations may be needed?
5) Examples of Disease-Specific Questions
- Based on our child’s facial, growth, and neurodevelopmental findings, how likely is it that the child will be diagnosed with FAS (or FASD)? What tests are essential for diagnosis?
- (If diagnosed) Which early intervention programs (such as speech, behavioral, and cognitive rehabilitation) would be most effective, and when and how should they be started?
Additional information: Because any alcohol consumption during pregnancy may be dangerous to the fetus, complete abstinence starting at the pregnancy-planning stage is the most certain prevention. Because the diagnostic and treatment plan varies depending on age, symptoms, and comorbidities, a multidisciplinary evaluation with a pediatrician and neurodevelopmental specialist is recommended.
