Abstract
Researchers at Departments of Neurology and Speech, University of Campinas, Brazil assessed the auditory processing function in children with language-learning impairment in relation to malformation of cortical development.
Highlights
Thirty-two children (19 males), aged 8-15 years, were divided into three groups: Group I included 11 children with language-learning impairment and bilateral perisylvian polymicrogyria, a malformation shown to be associated with auditory processing disorders; Group II included children with language-learning impairment and normal MRI; and Group III comprised normal children
Groups I and II showed abnormalities in auditory processing when compared with the control group, and children in Group I were more affected than children in Group II
Perisylvian cortical malformation correlates with impairment of auditory processing function
Summary
Researchers at Departments of Neurology and Speech, University of Campinas, Brazil assessed the auditory processing function in children with language-learning impairment in relation to malformation of cortical development. Thirty-two children (19 males), aged 8-15 years, were divided into three groups: Group I included 11 children with language-learning impairment and bilateral perisylvian polymicrogyria, a malformation shown to be associated with auditory processing disorders; Group II included children with language-learning impairment and normal MRI; and Group III comprised normal children. All patients had an IQ>80, only 1 had epilepsy, and 5 had pseudobulbar signs.
