Understanding ND-PAE & Fetal Alcohol Spectrum Disorders (FASDs)
This guide explains how prenatal exposure to alcohol affects brain development, leading to a range of lifelong cognitive, behavioral, and adaptive functioning difficulties.

Neurobehavioral Disorder Associated with Prenatal Alcohol Exposure (ND-PAE) is a condition included in the DSM-5 under “conditions for further study.” It describes a specific pattern of problems in children exposed to alcohol before birth.
ND-PAE affects three major areas:
- Cognitive functioning (thinking, memory, attention)
- Self-regulation (mood, behaviour control)
- Adaptive functioning (daily life skills)
Understanding Fetal Alcohol Spectrum Disorders (FASDs)
FASDs are a group of conditions that occur in individuals whose mothers consumed alcohol during pregnancy. These conditions include:
- Fetal Alcohol Syndrome (FAS)
- Partial FAS (pFAS)
- Alcohol-Related Neurodevelopmental Disorder (ARND)
- Alcohol-Related Birth Defects (ARBD)
- ND-PAE (DSM-5 category)
All FASDs involve brain-based differences. Some also include physical features and growth problems.
Causes: Prenatal Alcohol Exposure
Alcohol crosses the placenta and affects fetal brain development. Key mechanisms include:
- Damage to developing neurons
- Disruption of brain growth and connectivity
- Genetic vulnerability interacting with alcohol
- Impact on placenta and nutrient/oxygen supply
Symptoms of ND-PAE
1. Cognitive Symptoms
- Poor memory and learning
- Difficulty with maths and abstract thinking
- Slow processing speed
- Trouble shifting attention
2. Self-Regulation Problems
- Difficulty managing emotions
- Irritability, tantrums, anxiety
- Impulsivity and poor behavioural inhibition
3. Adaptive Functioning Deficits
- Poor daily living skills
- Difficulty understanding consequences
- Problems with money management, time, and safety awareness
Physical Features (Seen in FAS)
Not all children with ND-PAE or FASDs have physical signs, but FAS may include:
- Smooth philtrum
- Thin upper lip
- Small palpebral fissures
- Growth deficiency
- Microcephaly
Diagnosis: How ND-PAE and FASDs Are Identified
- Clinical interview with caregiver
- Developmental and neuropsychological assessments
- Behavioural rating scales
- Medical examination and growth measurements
- Assessment of prenatal alcohol exposure (when available)
- Evaluation of adaptive functioning
| ND-PAE | FAS / pFAS |
|---|---|
| Focuses on behaviour, cognition, and adaptive skills | Includes behavioural + physical features |
| No physical features needed for diagnosis | Physical features strongly support diagnosis |
Evidence-Based Treatment Approaches
1. Behavioural Therapies
- CBT modified for cognitive limitations
- Behaviour management programs
- Social skills training
2. Educational Support
- IEP / special education services
- Task simplification and structured routines
- Visual supports and step-by-step instructions
3. Skill-Building Interventions
- Executive function training
- Daily living skills coaching
- Occupational therapy for regulation and sensory needs
4. Family Support
- Parent training in behaviour strategies
- Stress management and community resources
- Consistent routines and predictability
5. Medications (Adjunctive)
- Manage ADHD symptoms
- Reduce anxiety or irritability
- Treat sleep problems
Case Example (Child, 7 Years Old)
Background: Child shows impulsivity, learning difficulties, tantrums, and poor adaptive skills. Prenatal alcohol exposure confirmed.
Intervention: Parent training + school-based IEP + visual schedules + simplified instructions + occupational therapy. Behaviour improved and child gained independence in daily tasks.
Practical Tips for Caregivers
- Use simple, consistent instructions
- Build routines and structure
- Use visual reminders and daily planners
- Give extra processing time
- Focus on strengths, not deficits
- Collaborate closely with school and therapists
Key Takeaways
- ND-PAE is a neurodevelopmental condition caused by prenatal alcohol exposure.
- FASDs include a wide spectrum of physical, cognitive, and behavioural impacts.
- Early diagnosis and structured intervention significantly improve outcomes.
- Family education and consistent support are essential for long-term success.
