Comparison of Alcohol-Related Neurodevelopmental Disorders and Neurodevelopmental Disorders Associated with Prenatal Alcohol Exposure Diagnostic Criteria

Objective: Recently, increased attention has been focused on the diagnosis of the most prevalent category of fetal alcohol spectrum disorders, alcohol-related neurodevelopmental disorders (ARNDs). In 2013, proposed criteria for neurodevelopmental disorders associated with prenatal alcohol exposure (ND-PAE) were included in the appendix of the latest revision of the Diagnostic and Statistical Manual of Mental Disorders. The concordance of the 2 sets of criteria is unknown. This study examines the overlap in diagnostic criteria for ND-PAE and the ARND Behavioral Checklist in children. Methods: Clinical charts from June 2013 to July 2016 were reviewed to identify patients with an evaluation for ARNDs and where the criteria for ND-PAE were also available. Results: The review found 86 charts with a diagnosis of ARNDs, which included the ARND Checklist and the ND-PAE criteria. We then calculated the sensitivity and specificity comparing the ND-PAE with the ARND Checklist as the comparison standard. The sensitivity was 95.0%, specificity was 75.0%, and the ND-PAE diagnosis correctly classified 89.5% of cases identified as meeting criteria for ARNDs by the checklist. The receiver operating characteristics resulted in a large shared area under the curve of 90.1%. Conclusion: The 2 diagnostic constructs of ARNDs and ND-PAE seem to be very similar. Both the ARND and the ND-PAE variables are written in familiar formats and could be widely used by a variety of health care providers.
