Computerized Neuropsychological Testing to Rapidly Evaluate Cognition in Pediatric Patients With Neurologic Disorders

Abstract

Computerized neuropsychological tests represent a viable method for rapidly screening cognition. The purpose of this study was to explore performance on the CNS Vital Signs in a large pediatric neurology sample. Participants included 166 neurology patients (mean age, 13.0 years; standard deviation, 3.2) and 281 controls (mean age, 13.2 years; standard deviation, 3.2) between 7 and 19 years. The neurology sample performed significantly worse on all domain scores and nearly all subtest scores. Cohen d effect sizes were small to medium for verbal memory (d= 0.44), visual memory (d= 0.40), and reaction time (d= 0.48) and very large for psychomotor speed (d= 1.19), complex attention (d = 0.94), cognitive flexibility (d = 0.94), and the overall composite score (d = 1.08). Using the criterion for cognitive impairment of 2 or more scores ≤5th percentile, 36.6% of the neurology sample was identified as having an uncommon cognitive profile. This is the first study to demonstrate the performance of pediatric patients with neurologic disorders on CNS Vital Signs.
