Early identification of neurodevelopmental disabilities (NDDs) is critical to a good prognosis. Several factors such as overlapping diagnoses can complicate this process and thus delay access to services. This study sought to identify meaningful clinical profiles, beyond diagnostic labels, in 194 children with NDDs referred to an assessment clinic. Cluster analyses were applied to eight selected behavioral and cognitive variables. Results suggested a cluster structure in which three homogenous groups differed significantly from one another: children who presented either (1) heterogeneous diagnoses and ambiguous profiles, (2) a clinical profile closely aligned to a classic presentation of ASD, and (3) emotional and behavioral challenges. These distinct profiles may have implications for assessment and clinical practices.
