Fetal Alcohol Spectrum Disorder (FASD) is a permanent developmental condition caused by prenatal alcohol exposure. Many individuals with FASD also have significant postnatal adversity such as neglect. Postnatal neglect can lead to neurodevelopmental differences that are similar to those seen in FASD. It is therefore important to delineate the impact of neglect from the impact of prenatal alcohol exposure. A study from the UK National FASD Clinic used clinical data assess the association of postnatal neglect with neurodevelopmental outcomes in patients with FASD.
New Insights from a National FASD Clinic
The cohort study analysed data from 99 individuals diagnosed with FASD. Each individual underwent a detailed, multidisciplinary assessment to evaluate their sensory, cognitive, and behavioural skills. These findings have established one of the most comprehensive clinical overviews of FASD currently available in the UK.
The study compared two groups: both groups had neurodevelopmental differences that are associated with prenatal alcohol exposure; however, one group one group also had a history of postnatal neglect, while the other group did not. This design allowed researchers to examine whether neglect altered developmental outcomes.
A Consistent Neurodevelopmental Picture
For practitioners, this highlights the fact that FASD often presents as a condition that resembles other neurodevelopmental conditions. A lack of specialist training and in-depth assessment pathways may lead to these patterns being misunderstood, and therefore misdiagnosis and under-recognition within UK services.
The key finding in this study was the clear lack of difference between the groups. Neurodevelopmental characteristics such as attentional differences (78%) and autistic/social communication profiles (68%), which are commonly associated with FASD, were just as common, despite neglect history.
This challenges the assumption that neurodevelopmental difficulties in individuals with this kind of history would primarily be due to postnatal adversity. However:
- Prenatal alcohol exposure is the primary cause of FASD, rather than experiences after birth.
- The presence of neglect did not influence the outcomes measured in this study.
However:
- This does not mean that neglect should be overlooked or viewed as harmless.
- It means that neglect did not change the presentation of the specific outcomes measure here (ADHD, ASD, sensory processing and adaptive functioning).
This distinction ensures that neglect is not downplayed, but that a common misconception is corrected, which has the power to delay FASD recognition and support.
Developmental Gaps within Daily Functioning
When investigating daily living skills, communication and socialisation, both groups were reported to obtain a lower developmental age than their actual age. Repetitive language was discovered to be an area of difficulty, meaning individuals struggled to comprehend spoken words and instructions, with the group displaying an average developmental age of 3.7 years. This delay of development was also displayed through daily living skills such as household tasks and community skills.
These findings emphasise the importance of early identification and implementing support systems to ensure that individuals with FASD have the opportunity to succeed. However, UK services still have an inadequate number of professionals trained in FASD support and lack the appropriate referral pathways.
Sensory Processing Differences
83% of participants demonstrated sensory processing differences, suggesting that sensory regulation difficulties are a key challenge for individuals with FASD. Interestingly, these differences had a higher prevalence in the group that had not experienced neglect (96% vs 67%). While this suggests that these differences stem from the neurodevelopmental presentation itself and not postnatal experiences, more work will be needed to assess why a group with additional risk factors had an apparently less severe presentation.
Why are These Findings Important for the Future of UK Services?
These findings explain how complex FASD presentations can be. They show that:
- FASD is linked to a wide range of neurodevelopmental differences that impact daily life and functioning.
- These differences remain consistent regardless of neglect history.
- As a result of this, individuals with FASD require specialised, coordinated and FASD-informed support from the services around them.
- Whilst neglect is known to be harmful, this data suggests that the neurodevelopmental characteristics of individuals with both FASD and a history of neglect may be primarily due to prenatal adversity than postnatal adversity. Interventions and support should acknowledge this.
However, support that is available across the UK does not match the level of assistance needed. Diagnostic capacity is limited, training is restricted, and many professionals are unfamiliar with the wide range of presentations detected within this study. For practitioners and academics, an increase in recognition is critical for ensuring that individuals have access to assessments and long-term support tailored towards their needs. The UK can only begin to meet the needs highlighted in this clinical cohort once these issues are addressed.
