Abstract
To characterize the presence and nature of discrete behavioral phenotypes and their correlates in a cohort of youth with new and recent onset focal and generalized epilepsies (YWE).
The parents of 297 YWE (age 8–18; n = 183) and typically developing participants (n = 107), completed the Child Behavior Checklist. The 8 behavior problem scales were subjected to hierarchical clustering analytics to identify behavioral subgroups. Factors examined included: demographics, neuropsychological data, history of academic problems, epilepsy characteristics, parental IQ and education, cortical thickness, daily executive functioning, and number of lifetime-to-date DSM-IV diagnoses.
Hierarchical clustering identified three behavioral phenotypes which included: no behavioral complications (Cluster 1, 67% of YWE), internalizing problems (Cluster 2, 11% of YWE), and combined internalizing and externalizing problems (Cluster 3, 22% of YWE). These behavioral phenotypes were characterized by orderly differences in the factors analyzed. Cluster 1 was most similar to controls across most metrics while Cluster 3 was the most abnormal. Epilepsy syndrome was not a predictor of cluster membership.
YWE fall into 3 distinct behavioral phenotypes associated with a variety of co-occurring features and comorbidities. This approach identifies important phenotypes of behavior problem presentations and their accompanying factors that serve to advance clinical and theoretical understanding of the behavioral complications of children with epilepsy and the complex conditions with which they co-occur.
