Co-Occurring Neurodevelopmental Disorders in Military-Connected Children with Fetal Alcohol Spectrum Disorders, 2016-2023
This study of military-connected children with Fetal Alcohol Spectrum Disorders (FASD) from 2016 to 2023 reveals that the vast majority have at least one co-occurring neurodevelopmental disorder, particularly ADHD, and that factors like male sex and non-parental guardianship significantly increase the risk of multiple co-occurring conditions, underscoring the need for routine FASD screening during neurodevelopmental evaluations.

Every child develops at their own pace, but for some, the path is marked by conditions that affect how they think, learn, and behave. One such condition is fetal alcohol spectrum disorder, a group of lifelong challenges that occur when a pregnant person drinks alcohol. This exposure can alter a child's physical growth and brain development, leading to difficulties with memory, attention, and social interaction. Because these symptoms often look like other common childhood conditions, such as attention deficit hyperactivity disorder or autism, doctors sometimes miss the underlying cause. When a child is diagnosed with one of these other conditions, it is crucial to consider whether prenatal alcohol exposure might also be part of the picture, as this changes how they are treated and supported. Understanding how these conditions overlap is essential for ensuring that children receive the right care at the right time.
Researchers recently turned their attention to a specific group of children to see how often these overlapping conditions appear together. They looked at medical records from the United States military health system, which covers the children of service members, retirees, and reservists. The study focused on nearly 1,500 children who had been diagnosed with fetal alcohol spectrum disorder between 2016 and 2023. The team wanted to know how many of these children also carried diagnoses for other neurodevelopmental disorders, which are conditions that affect the nervous system and brain function. They sorted these additional diagnoses into broad categories, including autism, intellectual disabilities, learning disorders, and attention problems, to get a clear picture of the complexity these children face.
The findings revealed that the vast majority of these children were dealing with more than just the effects of alcohol exposure. More than eight out of ten children in the study had at least one additional neurodevelopmental diagnosis. For nearly half of the children, the situation was even more complex, with three or more different categories of conditions present at the same time. The most common additional diagnosis was attention deficit hyperactivity disorder, which appeared in about two-thirds of the children. Following closely were intellectual disabilities, autism spectrum disorder, and communication disorders, each affecting roughly one-third of the group. The researchers found that while some combinations of conditions were common, the specific mix of challenges varied greatly from child to child, with most unique combinations appearing in very few individuals.
Beyond the medical diagnoses, the study looked at the family and social circumstances of these children to see if certain factors made it more likely they would have multiple conditions. The data showed that boys were significantly more likely than girls to have these co-occurring diagnoses. The family structure also played a role; children who were stepchildren or those living in guardianship, such as foster or pre-adoptive care, were much more likely to have multiple diagnoses compared to children living with their biological parents. The researchers also noted that children of Black race were diagnosed with these additional conditions less frequently than White children, a pattern that mirrors findings in the broader civilian population and may reflect differences in how and when children are evaluated by the healthcare system.
The study also examined how the military branch a parent served in and their rank influenced these outcomes. Children whose parents served in the Marine Corps or who held junior enlisted ranks were less likely to have co-occurring diagnoses compared to their peers in other branches or with higher ranks. The authors suggest this might be because junior enlisted service members often have younger children who have spent less time in the medical system, giving them fewer opportunities to be diagnosed, or because of differences in socioeconomic status. Ultimately, the research highlights a critical gap in care: because most children with fetal alcohol spectrum disorder also have other conditions, doctors should be screening for the alcohol-related disorder whenever a child is diagnosed with something like autism or attention problems. Catching the full picture early could lead to better support and improved lives for these military-connected children.
