Cognitive impairment in children with benign childhood epilepsy with centrotemporal spikes and attention deficit hyperactivity disorder: a prospective study / 中国当代儿科杂志

ABSTRACT

OBJECTIVES@#To study the difference in cognitive impairment between the children with benign childhood epilepsy with centrotemporal spikes (BECT) and attention deficit hyperactivity disorder (ADHD) and those with BECT or ADHD alone.@*METHODS@#A prospective study was performed on 80 children with BECT and ADHD, 91 children with BECT, and 70 children with ADHD , who were diagnosed with the diseases for the first time. Seventy children of the same age who underwent physical examination were enrolled as the healthy control group. Event-related potential P300, Wechsler Intelligence Scale for Children, and integrated visual and auditory continuous performance test were used to measure and compare each index between groups.@*RESULTS@#Compared with the healthy control group, the BECT+ADHD group, the BECT group, and the ADHD group had a significantly prolonged P300 latency, a significant reduction in the amplitude of P300, and significant reductions in the scores of verbal comprehension index (VCI), perceptual reasoning index (PRI), working memory index (WMI), processing speed index (PSI), full scale intelligence quotient (FSIQ), auditory response control quotient (ARCQ), visual response control quotient, full response control quotient (FRCQ), auditory attention quotient (AAQ), visual attention quotient, and full attention quotient (@*CONCLUSIONS@#Compared with the children with BECT or ADHD alone, the children with both BECT and ADHD have basically the same fields of cognitive impairment but a higher degree of cognitive impairment in some fields.
