title: Growing up with epilepsy: a two-year investigation of cognitive development in children with new onset epilepsy.
abstract: OBJECTIVE
  To characterize patterns and determinants of normal and abnormal cognitive development in children with new onset epilepsy compared to healthy controls.
  
  
  METHODS
  Longitudinal (2-year) cognitive growth was examined in 100 children, age 8-18 years, including healthy controls (n = 48) and children with new onset epilepsy (n = 52). Cognitive maturation was examined as a function of the presence/absence of two neurobehavioral comorbitiies (attention deficit hyperactivity disorder and/or academic problems) identified at the time of epilepsy diagnosis. Groups were compared across a comprehensive neuropsychological battery assessing intelligence, academic achievement, language, memory, executive function, and psychomotor speed.
  
  
  RESULTS
  Children with new onset epilepsy without neurobehavioral comorbidities were comparable to healthy controls at baseline, rate of cognitive development, and follow-up assessment across all neuropsychological domains. In contrast, the presence of neurobehavioral comorbidities was associated with significantly worse baseline and prospective cognitive trajectories across all cognitive domains, especially executive functions.
  
  
  CONCLUSIONS
  The presence of neurobehavioral comorbidities at the time of epilepsy onset is a major marker of abnormal cognitive development both prior to and after the onset of epilepsy.
