When families receive a HIE diagnosis in the NICU, the early conversations often center on survival, potential outcomes, and immediate medical needs. But for many families, especially those whose children were initially classified as having "mild" HIE, a different set of challenges can emerge a few years after birth.
Behavioral challenges are prevalent in our community. While early identification is possible between the ages of 3-5, most children are not identified until ages 5-8. The incidence is estimated roughly between 40-60% of those who do not develop cerebral palsy, and may be classified as having "mild HIE" from birth. Children with HIE are also more likely to develop anxiety disorders. As with all differences, early identification is key, and there are many strategies and accommodations that can be taught and implemented.
There is growing recognition that behavioral and mental health challenges are prevalent among children with HIE. What remains less understood is why these challenges emerge, how early they can be detected, and which interventions are most effective for this specific population.
Behavioral health outcomes, including anxiety, attention differences, and emotional dysregulation, have been identified as a priority area in the patient-centered research agenda shaped in part by our community. Families have consistently reported that these challenges often feel invisible to the medical system, particularly for children who appear to be developing typically in early screenings.
One promising area of emerging research involves earlier identification tools, such as the Babyscreen app developed by researchers at the Infant Centre of Ireland, that may be able to flag cognitive and developmental differences in HIE-affected children before school age, potentially enabling earlier and more targeted intervention.
The Neonatal Seizure Registry (NSR) represents another important vehicle for advancing our understanding of long-term outcomes. Registries like the NSR help researchers build the evidence base needed to characterize neurodevelopment trajectories across HIE populations over time, including behavioral and pyschiatric profiles.
There is hope with these differences and difficulties as well. Many children learn strategies to work around their differences and important skills such as self-advocacy, and there are many different accommodations that can be written into educational plans to help students adapt.
For children with a history of HIE, clinicians and researchers increasingly recognize the value of a comprehensive neuropsychological evaluation around school age. This type of evaluation can provide a detailed picture of how your child processes information, where their strengths lie, and what areas may benefit from support. Having access to this information can offer guidance for both your family and your child's educational team.
If your child's pediatrician has not yet raised this, you can ask for a referral. You may also request an evaluation through your school district.
For behavioral and mental health concerns, a child psychologist with experience in neurological differences can be a helpful support. Some providers specialize in pediatric neuropsychology, anxiety, or ADHD and many work in collaboration with school teams and can help both your child and your family build effective strategies.
Research increasingly supports the role of parent-mediated interventions in improving outcomes for children with neurodevelopmental differences. Parent coaching (working with a trained therapist or behavior specialist to develop strategies for supporting your child at home) can be one way to put that into practice.
The Child Mind Institute is a leading independent nonprofit dedicated to transforming the lives of children with mental health and learning disorders. Their website offers evidence-based information on anxiety, ADHD, learning differences, and emotional dysregulation, written in accessible, family-friendly language, as well as a directory to help connect families with qualified providers.
If your child has HIE and you've noticed behavioral or emotional challenges emerging, know that what you're observing is recognized in both the clinical setting and among HIE families and you're not alone. Connect with other families who understand and access resources through HIE.Support.
