The BREV neuropsychological test: Part II. Results of validation in children with epilepsy.

Abstract

The Battery for Rapid Evaluation of Cognitive Functions (Batterie Rapide d'Evaluation des Fonctions Cognitives: BREV) is a quick test to screen children with higher-functioning disorders and to define the patterns of their disorders. After standardization tests in 500 normally developing children aged 4 to 8 years, validation consisted of comparative evaluation of the specificity and sensitivity of the BREV with a wide reference battery in 202 children with epilepsy (108 males, 94 females; mean age 6 years 6 months, SD 1 year 8 months). Children were divided into 10 age groups from 4 to 8 years of age and represented eight epileptic syndromes. The reference battery included verbal and non-verbal intelligence assessment using the Wechsler scale, oral language assessment with a French battery for oral language study, drawing with the Rey figure, verbal and visuo-spatial memory with the McCarthy scale subtest and the Rey figure recall, and educational achievement with the Kaufman subtests. Every function evaluated with the BREV was significantly correlated with the reference battery testing a similar function (p=0.01 to 0.001). Specificity and sensitivity of the BREV verbal and non-verbal scores were correlated with those of the Wechsler scale in more than 75% of children. The BREV, therefore, appears to be a reliable test which has been carefully standardized and validated and is valuable in screening for cognitive impairment in children.
